Downshifting Problem?

At a recent trackday I was encountering a a strange feeling during a heavy downshift from 3rd to 2nd gear. I was downshifting at around 12000 rpm and going into 2nd from 3rd for a tight 160 degree turn (The bus stop at Grattan). Within a few seconds after the downshift the engine rev'd a little higher just like another downshift. It was not consistent with every lap only twice during the day. The F4i is an '03 with just over 6,000 miles, stock chain and sprockets, and standard tire sizes. I change oil before each trackday weekend with the HP4 synthetic blend 10W-40. Any ideas on what may be wrong if anything. TIA

Is the tire or clutch slipping?

Twisty, It is just before it hits the rev limiter in second. When is drops into second it is at 12000-13000 rpms.

Jeeps, I thought it was the tire slipping the first time but it is very smooth and did not give the weave that you get when the tire spins.

TIA

About 60-70% of the miles are on the track. Has anyone installed or used a Barnett Clutch Kit. Is it worth the $120.

Not on a bike like yours but I have never had on either.
Barnett is quality stuff.
The spring will be a lot stiffer.
Not to worry on a track bike but a daily rider could be tough.

I like stock clutches the best, a little more money but worth it imo...ive had bad luck with barnett clutches..I fried their kevlar clutch when it first came out after 3 runs on my gsxr11 with nos at the drag strip...never had a problem with stock clutches...

any clutch suggestions for the SV. I don't need one yet, I've got 17,000 hard miles on the original clutch, and clutch wheelies on the time.

Its pretty simple.
If you can take something apart and put it back together and it still work, than I would say yes.
Keep everything in order on dissemble and reinstall with new stuff in reverse order.
If your unsure. Enlist the help of somebody that is sure.

I'm pretty mechanically inclined so I'd say I could do it.

It will let you know usually with enough time to order a set before its gone all the way.
