686 running a bit rough
Intalled the 686 kit about 2 months ago and it has been working well since just recently, I havn't been on it in 2 weeks. Took it up to speed wot in 5th and it felt like some what of a missfire or possibly wrong jetting, it was 15 degrees cooler since last ride maybe that was the issue not sure myself, 190/195 jetting at about 1200ft above sea level. Any thoughts? thanks

here is a thing for the 686 kit just so you can double check yourself was it a backfire out of the carb or what was the sound like becuase it may be from downshifting at too high of rpms or the altitude...http://www.raptortranny.com/index.ph...d=20&Itemid=35

Well I just got done re jetting, went with 175/180 mikuni, while I had the plastics off I thought I would readjust the valves since they have not been done since the bore job, plus I was hearing a light tapping from the valve train. So I took it out for a quick ride and see how it worked (still heard the tapping), ran better then before but still up high in the rpm still felt like a miss, and then progressivly got worse (would start sooner in the rev range). So I am pretty much sick of the damn thing, but if anybody has any ideas... thanks.

p.s. I replaced the spark plug, just thought may as well.

Funny you ask that, while I was changing the jets i did notice it looking awful dirty, But i didn't think it could cause such a failure, so I am picking up a filter recharge kit tomorrow and seeing what happens. Do you think that a dirty air filter could cause a sort to say miss like that?? Thanks again.
