nater006 Posted March 10, 2004 Report Share Posted March 10, 2004 I've got the manual... says .028 to .032. I'm running a ported engine with Wiseco pistons and stuff, with the Toomeys and K&N and stuff. Someone mentioned gapping the plug a little narrower to help at higher RPMs and with a modified engine and stuff. The reason i ask is because of the sputtering at high RPM in my quad.. it is probably a jetting/spark issue from the sound of it but.. just trying to figure out all possibilities.

BdBanshee Posted March 10, 2004 Report Share Posted March 10, 2004 Plug gap will remain the same. Sounds like a jetting problem. Quote Link to comment Share on other sites More sharing options...

nater006 Posted March 10, 2004 Author Report Share Posted March 10, 2004 Its sputtering until it gets really warmed up. Then it seems to scream OK... A friend who's been doing the 2-stroke thing for a while mentioned that perhaps the stock gap was a lil too much and that it could be having spark issues at higher rpm, potentially, with a ported engine. Thats why I was asking... Didn't know what people run... or if people use smaller-than-stock gaps. Anyway, the reason I asked is because the high end kinda sucks until it is really warmed up. Mind you I run it really easy for a bit before I crank on it. It does kind of feel more and more like a jetting issue. Gonna go to the Stealership today and pick up lots o' sizes. The lows and mids feel fine.. so all that's left is figuring out the main jet (for now). Quote Link to comment Share on other sites More sharing options...
