Ibezy Posted February 2, 2017 Author Report Share Posted February 2, 2017 I've seen them super flooded and take forever to clean out I have opened the carbs up to try different jets, if it was flooded it should be fine by now; I also put in new plugs.

hoppedupandcutdown Posted February 2, 2017 Report Share Posted February 2, 2017 should probably do a real compression and leak down test, that idle screw is a huge air leak Quote Link to comment Share on other sites More sharing options...
phillybuilt Posted February 2, 2017 Report Share Posted February 2, 2017 Just curious, have you looked at the reeds? Maybe one chipped or broke? Could possibly cause what's happening here with no air leaks & seemingly everything else in place Quote Link to comment Share on other sites More sharing options...
RIPPIN' IT UP Posted February 2, 2017 Report Share Posted February 2, 2017 another point, it's been smoking out the exhaust a little more than it used to.Both sides or one? Sent from my ZTE T84 using Tapatalk Quote Link to comment Share on other sites More sharing options...
sleeper06 Posted February 2, 2017 Report Share Posted February 2, 2017 You really need to pressure test it and compression test it at this point. If that air screw cam out while riding you could have damaged the piston on that side. No sense chasing your tail if those two things don't check out Quote Link to comment Share on other sites More sharing options...
Gemeiner Posted February 3, 2017 Report Share Posted February 3, 2017 Sounds like it could be rich to me not sure why itd happen all of a sudden though. Sent from my SM-N920V using Tapatalk Quote Link to comment Share on other sites More sharing options...

Ibezy Posted February 3, 2017 Author Report Share Posted February 3, 2017 (edited) Quick question to everyone, does the bike need to be warmed up for the compression test? I just did it and it came up as 63 psi in both cylinders. The motor was completely cold, I have a feeling the tester might be bad, because the bike ran amazing a couple months ago and it doesn't even have 8 hours on the new top end.

But even cold will give you a rough idea. Also if it's a crap tester from Harbor freight then they all read about 60. Quote Link to comment Share on other sites More sharing options...
sleeper06 Posted February 3, 2017 Report Share Posted February 3, 2017 They always run amazing before they pop. See if you can borrow a known good one or use the one you got on a known good engine. Stock bore, what was the piston to cylinder clearance? 8 times outta 10 stock size pistons won't work and you need to bore it .010. If you just jammed pistons in you could have excessive clearance and it ran good until the rings finally lost there tension. What was the ring end gaps?
