BansheeBoy17 Posted July 11, 2005 Report Posted July 11, 2005 My engine has decent bottom to mid, then the top just sputters and skips like shit, I checked compression. Its 136 left and 130 right. Thats bored .040 with a milled .030 head. So that seems right. And I have tried jetting , and even different carbs but it doesnt change the problem. What else could it be? I just had my wiring re-done , i guess its a possibility it could be spark, im just wondering.. could an air leak cause this? Quote
Master of Faster Posted July 11, 2005 Report Posted July 11, 2005 Had the same problem with mine earlier this year. Turned out to be a bad spark plug cap Quote
tOj Posted July 11, 2005 Report Posted July 11, 2005 (edited) Please post your ideas guys we've been dealing with this for awhile. Edited July 11, 2005 by tOj Quote
broke Posted July 11, 2005 Report Posted July 11, 2005 It kind of sounds like an ignition issue to me too. Plugs look OK, right? Try to swap out the coil first, they are all the same. It's an easy one to start to rule out what could be the problems. Quote
rebelbanshee2 Posted July 11, 2005 Report Posted July 11, 2005 Is it RPM related or throttle position related? example can it be redlined in first with partial throttle and run clean or does it happen when you are at WOT? If it only does it at a certain RPM it is very likely electrical. Do you know someone with a banshe you can swap CDIs with? Quote

I cut my plug wires a 1/4 inch today im gonna see if that helps any. Havent bought any carbs yet tho, so I kinda need those first Quote

I was thinking that 135 was stock. should be a little higher with milled head and bored cylinders right? Or was 125 stock? TORS are gone right? Quote
wayfst Posted July 12, 2005 Report Posted July 12, 2005 due to the fact that the cdi can't be tested i just change it after everything else is tested. saved me alot of headaches like this. Quote
