'86 atc 250r
Awhile back I blew the base gasket on my R, and finally got it rebuilt by a local shop. It's bored .40 over, has a 38mm keihn carb, vforce reeds, port and polished head, and an fmf header now. It fires right up on the first or second kick every time, it idles good and sounds good. But the thing is it feels real boggy and when the powerband kicks in it ain't like it used to be. It barely cuts out when your in the power band its hard to notice but its there. Kinda seems like its loadin up and gettin to much fuel. I've put several new spark plugs it in and it hasn't changed any. So now I'm Feelin like the jetting needs leaned out some but I don't anything bout jetting sizes. I could really use some help on this one and I'd appreciate it, thanks. BTW I always run with just 87 pump octane would 91 make any difference now that its beefed up a little more?
