Alright guys. I have a 2001 440 that I completely built myself. Its got a Namura 440 Kit, HD Studs, 450 Timing chain, Uni filter, 450r Carb. All the good stuff. Well I bought this POS Sparks pipe and fixed it up to the best I could. Got a new cap and core and newly packed it. Well I started the bike up today and it idles, but it pops while it idles. It`ll stay running but it`s like pop-pop-pop-pop-pop. It also smokes pretty damn bad. As well as if I put my hand behind the exhaust pipe, I can REALLY feel the exhaust coming out on my hand, I mean HARD.
It also smokes a very white smoke.
Sometimes it will also rev up really high without me doing anything, then pop and shut off.
Any suggestions as what to do, jetting, or what?
