I run VP T4 in my stock fe650 and just started running it in my stock 505XCF. There is definitely some performance enhancement with this fuel.
Interestingly I feel more enhancement in the 650 than the 505.
Has or is anyone running VP U4.4, is it worth it and what jetting changes did you make?
Thanks!
