Super off topic here, but here goes. I got a 1999 Yamaha TTR225 a few months back, and I cannot get it to have power under load. So far, I've rebuilt the carb, replaced the fuel shut off valve, installed an E3 plug, and replaced the battery. I've even tried oversized carb jets, but those didn't help either. It starts up, idles and revs up fine in neutral, but when I put a load on it, it has no power whatsoever. For example, on a straight away, if I bump it into 4th gear and give it full throttle, it'll just sit at the same RPM and not gain any speed at all. I'd like to try to avoid paying a repair shop if at all possible. Thanks for any help or advice!
