Hey man!

That looks great!

The VFR on the very first picture looks exactly as mine now. I am preparing for a RC36 to CBR600RR conversion too! :)

Good luck with your project, looks awesome! ;)

Thanks man. I appreciate it. Here's an update, installed the subframe and exhaust and did most of the wiring. Just need to finish the wiring, make the exhaust hanger and install the fairings to go riding :cheerleader:

Assembled the bike and rode it to work and back yesterday :cheerleader: Here are a couple of pics after.

Did you notice my HRC rear brake reservoir assembly? Looked for it on ebay and took the part numbers from the item picture and ordered the parts cheaper from David Silver spares :laughing6-hehe:

Of course on the way back there were some wet spots and the bike got dirty or should I say even dirtier. There are some little things like the missing center stand to fix up still but it's finally drivable. Also I mean to hook up the lambda sensor to my mixture analyzer to check the jetting.

Oh and by the way, the new exhaust setup improved the sounds quite a bit, it sounds wicked :biggrin: I wish I had a video cam with a mic to make a sound clip for you guys.

So now that I have some kilometers under my belt this summer I thought I'd update a bit. All the mods work great apart from the licence plate hanger which I've had to reinforce a couple of times due to fatique cracks but I think that's sorted now too.

I've also done some performance testing and on the first try I achieved a 0-100km/h time of 3,96s which is 0,3s faster than last summer and it's backed up with a 3,98s and a 3,99s runs. It also picked up 3km/h of more top speed compared to last summer, tested in similar conditions and in the same place.

The jetting seems to be spot on all the way across the rev range according to my LED A/F gauge with factory 132 mains and needles set to 3rd groove, stock slow speed jets and pilot screws 2,5 turns out. The only thing I am wondering is that should the mixture be leaner while cruising at part throttle compared to WOT as with cars to improve mileage? My A/F ratio is the same as WOT while cruising. My mileage hasn't gone worse from last year so I presume it's ok as is.

So all in all I gained a little power and a 25kg (not weighed, calculated) lighter bike and have had a lot of fun building it :cool:

That being said the bike is far from finished as it needs a paint jod and a lighter front wheel (anyone have a spare 5 spoke R1/R6 wheel?) and anything my mind happens to come up with :goofy:

Good work sir!!!!! Love the finished product.

Can you post a YouTube video so we can hear the exhaust???

Thanks. But like you must know these are never really finished are they :biggrin:

That would be difficuIt as I don't have a camera that has a mic. I'll see what I can do though.

EDIT: My cell phone does have one so I give it a try although quality may be poor.

2nd EDIT, sound clip, used max. 5500rpm since the engine wasn't up to normal temp yet:

Turned out very good :cool:

I've now got a 5-spoke R6 wheel and appropriate 03-04 R6 rotors to mount this winter along with a Pilot Power front tyre. The front wheel weight is 4296g including bearings but without rotors and rotor bolts. The rotors weigh 1450g and 1457g, don't know why there's a difference but I don't mind.

Also I been contenplating a 520 conversion to reduce the rotating masses further. Also a Compu-Fire series regulator is on the way. Also thinking about leaving the center stand out as it weighs 3,27kg and not having it installed this summer hasn't been that great a loss.

So stay tuned, the winter is closing in although I did go for a ride last sunday. Currently it's raining and the temp is at about 10ºC so no seat time this week.

P.S. The best 0-100 km/h time is now 3,90s.

Nah, it's too cold here to do that :tongue:

Seriously, someone who could do a proper start on that bike could shave a lot out of that time. I'm only using those times to compare how my mods have paid off. I think it's pretty well for a bike that's seen 106000kms (that's about 66k miles).

I did a similar conversion but with a cbr subframe, used a tail light with intergraded turn signals and some sheet metal for a license plate bracket

Something I decided to see how it'd look:

seat cover

and fitting it:

15042012243

Of course I'd have to chop the stock seat seriously to fit the cover but I like the look :rolleyes: Don't really like the idea of cutting my only seat so if anyone has a cheap spare I'd be interested.

So now it's installed:

Now with a lighter front wheel it's much easier to change line mid corner and the Pilot Power front feels very good too. It was a little tight fit but everything fit with little modifications like shortening the spacers and collars to fill the gap between the R6 bearings and VTR axle. Here's a pic of the collars my dad turned for me in a lathe:

Congrats, looks great!

Thanks. I like the look too. The old wheel is about 5,9kg without bearings according to member VF1000RS's measurements and the new one is about 4,3kg with bearings so the weight saving is more than 1,6kg here. Did a few new 0-100km/h runs this morning and the best was 3,56s carrying the front wheel nearly all the way through the first gear. Wasn't expecting that much improvement but I like it :tongue: Only other change since last summers best run of 3,90s was the Compufire regulator which in theory could help a little but I doubt it would show.

The seat change is going forward. I'll let the pics do the talking:

The paint is just rattle can paint so in reality it's nowhere near as good looking as in the pic. But it'll do till I have time to do the the bodywork properly. A couple more pics are in my gallery.

Here's pic of my 520 conversion with a very dirty rear wheel :goofy: Sprocket is JTR245/3.45 machined for the VFR bolt pattern and lightened BLS style but without lightening holes by my dad.‏ I did ask for him to do the holes too but he did not have the time and thought they weren't that important. The sprocket weighs only 80g more than the aluminium 530 sprocket I previously had on it. The chain is considerably lighter and so is the front sprocket too. No performance figures for this mod yet. Also the seat has been changed to a lighter CBR900RR seat since last runs were made but I'll post the figures once I get around to test that. Right now I'm having too much fun learning to drag my knee and becoming better in it and cornering on the whole.

Nice. Good to hear you are working on the skills :fing02:

I do think it is important :cool: I may have driven bikes since I was young but I do find myself making stupid mistakes from time to time while driving and one can never really be too good a driver to stay safe out there.
