I installed my kit last fall, I'm sure we had one o-ring left over from the kit.As long as you replaced all of the obvious seals you will be fine.You will love the kit when you get the jetting sorted out.

While we are here, how about a few reviews on how the BB SXf runs???

I see Travis has a real 350cc kit & my dealer has a leftover 250SXf,,,hmmmmmmmmmm

That new SXf350 couldn't be as light as that modded bike IMO.

Thats a tempting combo, no??? I loved my 07 250SXf, adding gobs of low/mid could only be better IMO. The things gotta have some crazy snap!

How do the 280 & 300 BBs do? I admit I have very little knowledge of them. Ridden a TE310 but its not a huge dif from the regular 250 Husky.
