Good stuff and thanks for sharing. Glad Rob was able to help out the embedding. :woohoo: BR

The air works as a secondary spring, it will effect the full range of travel some, but has the biggest effect on the last portion of travel and can be used to help prevent bottoming. It is a tuning tool and all you need to do is +/- cc's of oil level. :blink:

Jason, Don't worry about it, just ride the thing as you are SO close to perfect as is. We just wanted to see what that small change would do. I just went 100 lbs stiffer and don't see much of a change except maybe gaining some free sag, but I'll have to do a two person re-check of the Ohlins w/1050 lb spring. :blink: I think I'm .925 or .950 w/1150 lb rear now on the street Vtec and .950/1050 on the track Vtec. BR

Sounds good! :fing02: I just installed a Penske on my street Vtec with a 1150 lb spring. With 10mm of pre-load I got 32-33mm Rider sag(in gear) with 9.5mm of free sag, pretty happy with those numbers and I weigh 185-190 at the moment! Finally changed my fork fluid after 40k miles! :blink: Now I just need to got out on it and work of rear shock settings. :wheel: My Ohlins has the a 1050 lb spring and I think I got 10/32mm on it? BR

TC, Looks like it's a good fit for a 5th gen length wise as the VTR shock is listed at 326mm where the 5th gen is 325mm & the vtec is 317mm. Stroke is 63mm vs 58/53mm for the VFR800's. If it's an aftermarket VTR shock like Ohlins or Penske that has ride height adjustment then it might adjust short enough for a 6th gen. :cheerleader: BR

F4/F4i are both 43mm tubes and the 5th gen uses 41mm tubes so no. If your willing to De-Link the brakes then you can just slap a full set of F4/F4i forks on the bike and have fully adjustable forks. The F4/F4i fork lowers do nothing for you! :biggrin:

Worthless w/o pictures! :angry: Congrats, now show us your work! :mellow: BR

Have you check free & Rider sag on your bike since dropping to 145 lbs? I would venture to guess that at 145 the front is too stiff now and the stock 929 shock wouldn't be to far off(check #'s). I would just drop in some .85 in the front and see how the valving feels. Measure the stock 929's free & rider sag and go from there, I would think a 17 kg rear max. If you plan to remain at 145 you won't want the .95's at all IMO & and making the entire bike Too Stiff for balance is not a good approach IMO. BR

Just PM coderighter, he's the man. Avoid your local shop as he's an idiot! :angry: The whole point of autotune is to eliminate the need for a custom map made by a Dyno guy. Makes the dyno guy an un-needed part of the equation. Yes there is two 02 spuds and only one sensor, but I'm not sure what you need to do here. Again PM coderighter. :laugh: PS I think there is a download of the maps coderighter made for his 06 around here somewhere. :fing02: Good Luck BR

"Least Favorite Mods" And all this time I thought this thread was about me, Boy I feel better now! :goofy: BR

No, your right. The rebound valve is attached to the bottom of the tube(hollow) so as long as you use the F4/F4i tube in the VFR cartridge the rebound needle with be right where it needs to be in relation to the rebound valve. :comp13: Was thinking of something else I guess. :wheel: One of the suspension shop guys just modded the top out spring on the F4 cartridge assm in order the make the F4 cartridge work. I guess either way will work if set-up right! :fing02: BR

Thanks BR! I knew a quick answer was out there. Now, if you don't mind, I have a couple of follow-up questions. Do I just swap the F4 tubes into my VFR or do I use the F4 steering stem and the VFR upper triple tree? I thought the F4 tubes are 43mm and the 5th gens are 41mm. Do I need to get a different triple tree? RE: spring rates, I weigh 220+ lbs buck naked so I'm looking at getting a set of Traxxion fork springs to bring the spring rate up into my weight class. What are your thoughts on the steering stem bearings? The bike only has 15k miles and while I have it apart I can replace or upgrade. Also, if I pick-up an F4 rear shock do you think the shorter fork tubes and shorter shock would keep the steering geometry about the same? Thanks for your help... As FM said you would have to use the F4 or Vtec triples for the 43mm tubes. Using F4 triples will change the Trail because the F4 tube to stem off-set is closer than the VFR. This could be good or bad depending on what you want. Trail numbers are Not my expertize! :fing02: Vtec triples will keep factory number much closer or the same vs F4 trees. At 220 lbs you should be running at least .95 kg fork springs and a 1200 lb rear spring, you'll have to decide on what other valving mods you'll want and for sure I would install either the F4/F4i or 929 shock with a 1200 lb spring on it, ideally have that shock revalved to the 1200lb spring if it's in your budget. If you are Inseam challenged(short legged) you could take advantage of this mod to drop your bike, but there's close to a 3 to 1 ratio on the rear so if you installed a F4i rear shock which is aprox. 3/4" shorter it would drop the rear of the bike around 2.250". :wub: That's a bunch and if you didn't drop the forks the same amount(not really possible) the bikes balance & rake would be way off. So if you had the forks 12mm higher in the tubes you would need a shock only 4mm shorter than stock to match it. :biggrin:

Sam, I don't see how it would be possible to Not use the F4/F4i cartridge and expect to have any rebound adjustment as the length of the rebound rod is specific to the length of the cartridge. If you used the longer VFR cartridge the adjusting rod end(needle part) would be no where near the valve orifice it's trying to regulate! :fing02:

YES! It's a basic bolt in swap, with the only concern is the shorter F4 tube length. I run F4/F4i forks on my Vtec track bike and if you run the forks slide up 10mm from stock like I do On my street VFR (for quicker turn in) then you'll have enough fork tube to clamp the clip-ons to. They (tubes)might be slightly lower than the top of the clip-ons but shouldn't be an issue. The F4 happens to run the same fork spring as the stock VFR(.74's) which are too soft if you weigh over 150-160 lbs. Stock VFR wheel and rotors can be used, but you will most likely need to use the F4 axle and play with spacers from both to center up wheel. I think if your planning to De-link it's a great & easy swap. BR

Installing a 6th gen cooler will add an extra row of capacity! :fing02:

I run the 16/43 on my 5th gen and don't see that(raised rear) as an issue. :fing02:

I think there is some question on whether the 950 lb spring is the correct rate for TC's weight! He was able to get desired Rider Sag, but were not sure about it having Any or proper Free sag. We plan on installing a 1200 lb spring on this shock soon and testing results, we'll post Free & Rider sag numbers as soon as we get them. :wheel: BR

I would suggest the 45(ever 46 if you 2-up a bunch) rear for sure and unless your slab the whole way at 90 mph I doubt it will effect mpg much at all! :biggrin:
