pinging in exhaust

[Drturbodiesel]

Hey welcome to banshee hq. I'm a new member aswell. I just figured I share my simalar experience. I recently bought one that's doin almost the exact same thing. I determined I have weak compression on the side doin that. Mine is exactly like it came new no mods and never been rebuilt. It doesent matter tho if it's tame mild or wild like some of the other guys said I would chech compression on both sides and compare as a starting point. Then move on to leak down if that's good. If leak down and compressin are good then I woul move on to fuel and spark. Good luck let us know what u find.

I took the bike for a ride today and it wouldnt idle and then it started revving real high on its own at idle. when i would try to ride it would bog and cut out from 0 to about 3/4 throttle then kick in and go sometime wouldnt go at all. i brought it home and pulled the carbs and they arent that dirty but i need info on the jets, the main jet says AB290 and the body of the needle jet says 345 0-8, also the pilot jet is 27.5 is this ok for 2300 elevation and just exhaust and intake?

and it looks like someone took a dremel to the factory reeds

Now it's sounding like an air leak

x2......if it starts reving up on its own then you have an air leak in your motor. 2stroke motors....when leaned out (not enough fuel)....will actually naturally "free-rev" or "run away." This is not a good situation as your fuel and oil is mixed together and when you are not getting enough fuel to your pistons your pistons will begin to scrape on the cylinder walls and cause chaos in your motor. This will cause you to have to rebuild your topend (possibly your bottom end if your bearings cant take the abuse of lack of oil) way way sooner than you ever anticipated....

here is a pic of the reeds

and here is the jet from the right carb

Don't ride your shee no more & yes you have an air leak. Get a leakdown tester & check for leaks. Find the leak & fix it before it cost you alot of money. Speaking from experience.

I took them off for the picture. Thx for the info guys I'll find the leak hopeful this weekend when I have time. Does anyone know if the jet sizes are fine for my elevation?
