toytech Posted September 2, 2012 Report Posted September 2, 2012 I have a shee with a playdune port, it has a bad miss on the top end, we have changed al the electronics from a perfect running shee onto it .we have been all over the board with jetting,nothing seems to change it. Could the flywheel magnets be bad? runs great on bottom and mid. Starts good to. Any ideas would be very apreaciated. I'm on my phone so I can't use the search on here. Quote
sheerider11 Posted September 2, 2012 Report Posted September 2, 2012 Pull the flywheel and give it a good shake. Stator will also give you a miss Quote
toytech Posted September 2, 2012 Author Report Posted September 2, 2012 Thanks, the flywheel doesn't rattle when you shake it . The stator was swapped with another shee and that one still runs great . I'm confused we have tried everthing I can think of . Quote
toytech Posted September 2, 2012 Author Report Posted September 2, 2012 Would both cyls miss if the crank seal on the stator side was bad ? I havnt done a leak down test since this started missing. This all started when it wouldn't start one day, no spark, tested the stator it had an open circuit, found a wire on one of the coils bad. Also replaed the coil.,and wires and plug boots. Desired the harness and installed a new style cdi. Still have the miss. Quote
bluebanshee98 Posted September 2, 2012 Report Posted September 2, 2012 i had a high end miss on my shee awhile ago. i replaced the spark plug caps ($7) and it screamed since its a high end miss and you have replaced most of the electrical like stator with a know working one i would try that. make suret he spark plugs are on pretty damn tight. i thought mine were tight but they were not so i replaced them with new ones and problem solved. get back to us and let us know if it works Quote
sheerider11 Posted September 2, 2012 Report Posted September 2, 2012 What about the caps? Ohm them out. You can trim the wire back a bit and see if it helps. Edit: didn't see the post above. Quote
toytech Posted September 2, 2012 Author Report Posted September 2, 2012 (edited) Swapped the coils to and the other shee still runs great We did plug chops, looks rich. We jetted down until it wouldn't run and the plug chop still looked rich ? Edited September 2, 2012 by toytech Quote

toytech Posted September 2, 2012 Author Report Posted September 2, 2012 As well as you can with the way it runs. Warn up put new plugs in ,start wot 1-6 shut down Change plugs go read plugs . Quote
toytech Posted September 2, 2012 Author Report Posted September 2, 2012 (edited) Yes, they are good . Replaced them at the begining of the season. Edited September 2, 2012 by toytech Quote
SonOfSand Posted September 2, 2012 Report Posted September 2, 2012 Gap your plugs down to .018 and buy some spark plugs that have solid tips... or at least make sure your screw on tips are on TIGHT! Stator pickup was at spec? Quote

Stator pickup was at spec? I'll try .018 plug gap. the pickup was at spec, I will check it again though. where can I get plugs without the screw on caps? Edited September 2, 2012 by toytech Quote

Probably any checker or autozone... but here is the plug I run and LOVE! Ask them for this plug.. they might have to order it in for you. http://www.amazon.com/NGK-BP8ES-Traditional-Spark-Terminal/dp/B001RMA6SQ Quote
