Thanks, main-175 pilot-48 needle-2 ...... we had pro circuit pipe on before, but we put a FMF GYTR pipe on but didn't change jets. they required 178-50 and 3rd needle position ... bike ran good, so we made no changes. We also run VP 110 "100%" at 30:1 fuel to oil mix.

Yep, find out this week what came apart first. Thank you for watching, this video has about 5 hours of editing ;-/ tried to edit as fast as i could ............ kept seeing flaws after each view, finally just got tired. Thanks motomanfilms, talking to you last week and viewing your channel inspired me to get at it.

Oops, just noticed that wiseco was spelled wrong ...... we fixed it, should we upload the correct one?

Thank you, No, can you give us heads up on that.
