EXACTLY! This thread got me worried as well.Firstly any idea why your smoke test ended up with smoke out your exhaust (with the air injection deleted)? It should stop at the intake or exhaust valve inside the chamber, unless you just happen to catch a smidge of camshaft overlap (seems unlikely).
Mostly from this thread I hope this doesn't happen to me. Last year we drove about 14 hours to get to the mountains for a ride weekend and rode trail systems up to ~10k feet. All of that for this immediate off the trailer outcome would be terrible trip. My completely stock machine was a complete slug, especially ran like complete crap initially but seemed like it "adjusted" to a tolerable state, and I was able to make it mostly work out but was an absolute chore powering up some of the climbs. Once I get this GYTR Turbo kit installed I have no way to test it otherwise as there is no where close to get any elevation around me. That said if you ever figure anything out please circle back, I'll keep the spare parts around just in case.
BUT, after reading through and following along, I really have to believe that what happened is a mechanical issue somewhere. You said it perfectly in your post #38 when you mention something going awry.
I also think that Albas tune allows better tuning because they don’t have to tune around parameters dictated by CARB. Yamaha does and is also working around a restrictive catalytic exhaust.
So, I will go forward with eyes wide open and install my kit at the end of this month and hope for the best. The majority are not having issues.
And I sincerely hope Spotsjd gets this figured out and reports his findings. It ultimately helps out everyone here.
