I'm trying to add heated grips to my 2010 VFR 1200

is there a technical reason you can't use a newer (more available) OEM Honda heated grip?

The Africa twin 2016 OEM heated grips are available and look to have the same hookup for throttle cable and dimensions unless I'm mistaken, the part in uncertain of is it possible?

I'm sure the plug itself is unlikely to simply work but that's an easy enough fix, any help would be appreciated

I'm sure they can be made to work.

Wiring will just require connecting the right stuff and same 7/8" handlebars so should be possible to physically fit them. However, both those tasks may require some thought and modification to make fit. I doubt it will be simply plug and play, but I see no reason why they cannot be made to work.

I seem to have finally been able to change my email address for the forum (so different servers in the route for any notifications to me) and this morning I received a correctly formatted notification from a different thread, so rather looks like one of the intermediate servers used for my former address was having the dmarc problem. However, it does suggest there is an actual problem with this site's email. I've just been able to sidestep it.

Have to see how things continue.

Logged out of the site and back in and I am now able to post without problem. No idea what the actual problem was, but it's specific to this site. As I say, everything else works perfectly. Also cannot really say if this morning's problem is related to the email notification/mime problem which is still occurring.

Nope, same sparse HTML. It's not interpreting the mime format at all.

Also, this morning I was unable to reply to this topic. I click on reply and I see the box to type in the reply but that immediately disappears and back to the original page for the topic. I restarted Safari (I'm on a Mac), but no better. Tried it on another Mac and that worked. Tried Google Chrome on my Mac and seemed to be OK, but not logged in. Logged in and get same problem again. 

Back to main forum page (in Chrome) and then to this topic again (no more login parameters in URL) and it works so I am able to type this.

Since everything else is working perfectly as always, I can only assume that this site has made some changes which are screwing up some users.

Recently, all notifications I receive regarding new messages to a followed thread (may not be limited to just this one thread) are just pages of HTML code, rather than the formatted message. I have not changed anything my end and all other email is working fine, but VFRD notifications are garbage.

Looking at the raw message I see the following:-

X-Spf: ⁨Received-SPF: permerror (smtp04.mailcore.me: error in processing during lookup of domain of vfrdiscussion.com: Could not find a valid SPF record)

and lower down:-

Authentication-Results: ⁨dmarc.icloud.com; dmarc=fail header.from=vfrdiscussion.com⁩
Authentication-Results: ⁨dkim-verifier.icloud.com; dkim=fail reason="key not found in DNS" (0-bit key) header.d=vfrdiscussion.com

I don't know for sure this is new as VFRD notifications have not previously been a problem causing me to check. Have there been any changes to the notification messages that might be causing this? Anyone else seeing it?

Hopefully any reply here will not suffer the same problem.

ahhh, so stock cams? interesting...

If you're referring to Mohawk's bike, then that would be wrong-ish. Their profile is not stock at all (based on RC45), but I seem to recall he had stock cams reground rather than completely new manufactured items. I could be wrong about that last though.

I do however think we are straying way off topic here and we should really be sticking to the WILD exhaust system. I am far from blameless in this I know, but I think we should get back on track and curtail our 'flights of fancy'.

sorry, I'm talking out my ass....I have not ridden one.  just looked at the specs. and also the fuel consumption is apparently not great.  but like I said , in that genre its one of the best looking bikes!

Don't believe everything you read. Fuel consumption of the VFR1200 is not the problem idiot journalists made it out to be. Not a problem at all.

challenge accepted! 🙂

 150hp is needed to match the 1200 power to weight .... assuming a few pounds of weight loss, so yeah thats a tall order and sounds like supercharger territory, Im sure Ive seen 160hp dyno chart somewhere????

 

see, I had an aprilia rsv1000 and I spent a lot of time trying to make that thing comfortable. I decided to sell it and now I have a VFR (3 bikes later)

 

For me at least, I like to modify things. best to start with a bike I really like to ride and mod it....it is MUCH more about the journey and having something unique. sure I can get a K1200 or something but there is a bunch of stuff I don't like about that bike that is insurmountable.

 

I don't want JUST a fast bike. I want all the things the VFR has to offer and then I start modifying it to make it mine, make it special and enjoy the journey. Turn up on a R1 , the guys say "ok cool there is an R1, nice bike" . Turn up on a supercharged VF800 with trick and custom bits all over it and they say "damn, that thing is sick!!!". not that I care, its more about knowing that it is something I have created.

 

But that's just me.

Yes I get the customise thing, as Mohawk will testify, I'm not a standard bike kinda guy either. But trying to extract huge power increases, to me means I started with the wrong bike. Particularly as actual engine performance has virtually nothing to do with how fast I may, or can ride.

yeah it (vfr1200) might have 170hp but its a bit of a pig.  but now I look at it the power to weight is quite a bit higher.  always loved the look.

 

Doesn't have to be anything like a pig. My eVo4's plenty nimble and fast enough. Just ask Mohawk. 😀

140....I assume that's supercharged. if not then where do I sign!

Mohawk is not at 140. More like 120 something, I forget exactly what. I've ridden with him and it's a nice quick bike.

I still wonder though at trying to make a bike go faster. Seems a bit of a fool's errand.  Why not just buy the faster bike in the first place. Not like they're in short supply and nothing, I mean NOTHING will ever make a VFR800 go like e.g. a FireBlade. Or a VFR1200 come to think of it.

Flya, you’ve hit on the difficulty in interpreting dyno charts - what do they mean to the way a motorcycle actually rides? If one is lucky enough to take the two motorcycles in question  - Hammerdrill’s 6 gen and Samuelx’s 8 gen - out for a 100 miles or so that includes a bit of city surface streets, a bit of freeway, and healthy helping of one’s favorite twisty roads (I was exactly this lucky), the conclusion drawn would actually be that the 8 gen has more power, and certainly more grunt. This impression comes from the midrange, and my subjective opinion Is that unless we are riding our VFRs on a racetrack or our favorite twisty roads also include 1/2-mile or longer straightaways, we don’t get to tap into the top end power of our motorcycles very often at all. Midrange is where we reside and midrange is what gets us out of a corner. This header project has helped me develop a great respect for torque and hp numbers between 6000 and 10,000 rpms, and it’s taught me the value of professional dyno tuning to precisely and deliberately make both curves - torque and horsepower - smooth and linear so the motorcycle is very pleasantly and eagerly responsive In a predictable manner.

In simple terms, max. power only determines top speed. Torque determines how quickly you get there.

wow. thats good news for crosstourer owners, upgrade headers and remap and bosh massive power increase!

 

does the crosstourer have much more low down torque? in reality all these detuned engines just seem to be completely neutered in all areas. 

Sadly, whenever a manufacturer says they 'retuned' an engine with the implication that they may have dropped power, but increased torque, the reality is usually they simply lopped off the top end, with maybe a slighter fatter torque curve, but rarely is it actually higher.

Don't get carried away with thoughts of the apparent extra power of the 'F' model though. Horsepower only determines top speed. Torque is what gets you there.

1 hour ago, Coxylaad said:

eh?! surely not! so an exhaust change, and ecu flash and you go from 127bhp to 170?!  seems like a massive leap in performance. 

 

 

Well the ECU has complete control, as we know from multiple ride modes on other bikes that can cap the performance. The smaller diam. headers on the CrossTourer will increase torque while restricting top end power and with different ECU mapping that's all that's required to change the engine characteristics. You can check, but I'm pretty sure that when I did I found the pistons, heads, cams and intake stuff is the same on both bikes. Makes huge sense from a manufacturing point of view.

Interesting, I didn't realise how close they were!

Literally the same engine. The exhaust was pretty much the only way they changed the power characteristics - well and the ECU mapping of course. Intake and cams etc are all the same.

I'm not actually sure about the tank mountings. They may even be the same. More likely the front, but maybe even the rear. Don't expect a 'drop-in' replacement on a VFR1200F though. The tank sides are completely different so plastics just wouldn't match up. However, for a one-off naked special that wouldn't be an issue. I considered it for my eVo4, but 180 miles range is enough for me.

Coxy and I have been discussing this since almost the beginning and I truly admire his abilities to create his own frame. But I still wonder, why. Honda did the hard work and made a great frame in cast alloy, why bother with all the effort to make a steel version. But that’s JMO and I still admire his craftsmanship.

Regarding the tank size, I have frequently achieved 180 miles of fast riding (not motorway) on a tankful and to be honest, have no desire to go further without a break. But if you want more, a CrossTourer tank is bigger and an easy swap, but looking at the merged VFR and Yamaha tank makes me wonder if an SP-1/SP-2 tank could be more easily massaged to fit. 
 

Now we just need to crack Honda’s unique and proprietary serial protocol and a better choice of dash would be possible.

Ha, maybe that’s the cause of their recent global hack. Someone was trying to decipher that VFR serial protocol. 😀

I have been following this thread with interest, but have rather lost track of what's available.

I am interested in a system that would fit a 5th Gen 800 motor, with 8th Gen front rads and high level underseat mufflers like the 6th Gen. I expect to have to make my own link pipe to the high level mufflers I will be using. Would I be correct in thinking that this is all possible with one of these systems?

If so, then I'd like to place a deposit for final delivery to the UK.

I'm also working on an RC46=>RC45 replica so all info on similar projects is of interest.

However I have NO intention of eliminating the Single Sided SwingArm as that is so much a part of what makes an RC45. Yes I know, they did try double sided at the end of its racing career, but it was never actually produced with that. For me, it has to be SSSA.

…Also, the ZX-10R uses 210mm fork spacing (the triples are 214mm) …

Sorry to dredge all this up again, but just came across this. What the hell does it mean?

I guess 214mm is the forkleg centre spacing and that matches what Honda often use on larger bikes, but what's 210mm? There simply cannot be 2 different fork spacings on the same bike.

????

Only just seen this. It's a while since I did this work, but checking the parts list again shows that as I recall, there is a spring circlip on the end of the shaft as it pushes into the FDU. So to pull the shaft out requires pulling hard enough to overcome the circlip trying to stay seated in its groove. I don't now remember how hard it was, but I'm thinking it will be a fair old tug. That's why trying to push the FDU back onto the installed shaft is basically impossible as the shaft telescopes shorter rather than the circlip allowing the shaft to slide into the FDU. So you need to fit the shaft to the FDU, then install that assembly into the S/A. To have 3 hands would help with that.

Regarding the rear brake binding, I do recall the carrier being very close to the rotor, but as long as it's not actually touching, that's ok. I cannot imagine how it could be assembled with the carrier in the wrong place. Also if the binding occurs after braking, that would suggest it's a problem with the caliper.

Mind you, if yours is DCT, there's 2 calipers and I've never worked on a DCT.

You may of course have sorted it by now, in which case, what was found to be the trouble?

I understand that I might be asking a lot here... but is there a chance of doing a test fit of the new 8th gen header prototype on a 6th gen before they go into production?

I'm with Seb on that.

I sent Simmi/ Jeff an email to see if I could still get a set sent to the US, since I haven't been able to find a supplier over here, but have yet to hear back from them.  If I can get a hold of a set, I plan on getting it on the dyno for tuning.  Might as well do a before and after too  (05 with 7k miles on it at sea level).

 

If anyone needs help with forwarding a system to the US (or elsewhere), I would be prepared to have it delivered here to me in the UK and send it on to the buyer who would have to make the arrangments and any payments as I'm not currently fully mobile. Obviously it would be simpler for the seller to ship it direct, but if that proves impossible I would do what I can to help.

If all goes according to plan, the new 8 gen headers will be the same as the new 5/6 gen headers from the collector exit all the way forward [including the rear primaries] until the front sections of the two front primaries.

 

Ken, yesterday Wade assigned us homework that pertains to your question about 6 gen fitment : to help foresee any fitment issues with the collector exit of the new headers for 8 gen, we are going to attempt to fit OEM mufflers and aftermarket slipons from both 8 gen and 5 gen to both of those bikes - gonna throw a multi-pipe mini-swapmeet party. Four mufflers, two bikes, no rules, best fit takes all. Even if the muffler hanger mount holes/brackets are in different locations, we will get a rough idea of whether collector exit length, angle, and position line up between the two motorcycles. If they line up as expected [Or should I say as hoped?], we can relax a tiny bit.

 

Fitment of 6 gen dual high mount mufflers can be extrapolated from the results of the 8-5 gen muffler exchange matrix because we had to cut 5/8" off the new 5/6 gen header's collector exit before the 6 gen OEM mufflers fit correctly on a 6 gen motorcycle. After the cut, OEM 6 gen mufflers fit perfectly.

I look forward to the results of your 'swapfest' 😀

I am not aware of anyone mounting 6G pipes on an 8G bike,  though I have seen many 5G high mounts (Staintune and others) mounted on the 8G.

 

I dont think the undertail on the 8G would support the weight of hanging the 6G exhaust from it.

I cannot imagine any subframe capable of carrying 2 persons plus luggage would have any difficulty with any relatively minor weight increase due to a high level exhaust. Honda systems may be a bit weighty, but surely not that heavy.

Anyway, my requirements are not for actual standard models, but they will both be using front rads hence the need for splayed front headers while needing the outlet suitable for 6th Gen high level pipes and mufflers. The 5th and 6th Gen both use the same outlet dimensions, so either a 5th Gen low level or 6th Gen high level could be fitted to either (or so I am told), but is that also true for the 8th Gen? Is the collector outlet the same?  There was mention in here that the only difference for the 8th Gen would be the splayed front headers which implies the outlet is the same, but has that been determined?

One of my projects IS using a 6th Gen back end and high level exhaust, but with front mounted rad(s). The other will also be high level, but although not necessarily VFR 6th Gen, makes sense if both bikes use the same system.
