Hi all, I own two Yamaha TT600's, one in rebuild the other running....well hmm sort of....anyway my issue is this, the bike starts easy,idles perfect but when going over 60km's per hour or when you start gunning it, the bike changes completely, she starts backfiring and gosh knows what else ....it really sounds like a timing issue when you rev itr high... Changed the following : CDI,coil, stator, carbs.....to no avail, i cannot understand this problem...building engines is a walk in the park but this bike is killing me lol Any comments would be highly appreciated..
