Been ridin' and enjoyin' my 96 Savage this summer. Have it set up pretty much the way I want it. The bike runs good and pulls strong. Only one issue that kinda bugs me; the exhaust backfire. I have several other 500 & 600cc singles and none of them has this annoying issue. Seems like every time that I shift to the next gear the exhause backfires; just one fairly loud pop and then that's it. I usually shift at around 4000 rpm. I don't get any backfire on the over run, just when I'm shifting up through the gears.
I am running the stock carb that has been rejetted as per the recommendations on this forum. Idle mixture plug removed and the mixture screw adjusted to give the best idle. I'm running the stock air box with a K&N filter and no cover. The exhaust is the stock pipe with an extension on the end and a D&D exhaust can. When I got the bike it had a Super Trapp muffler and a from the factory stock carb. It had the same backfire issue set up this way as well. Can this have anything to do with the air cut off diaphragm? I haven't checked this yet. Was just wondering if anyone has a cure for this backfiring issue? Carry on!! wiguzziman
This is probably the TEV
