Ok so I am new at the whole 2-stroke thing but have learned a lot lately...

here is my problem. I just rebuilt the Top-end of my banshee it is now bored 30 over, I had 290 main jets and replaced with 310 since I was running super lean... This seems to have been the trick. Any comments ??
Also one cylinder does not seem to be firing the same as the other ? I typically am running at sea level. Plus I notice that one seems to blow a little more smoke then the other...

I think most of this is related to the carbs not being synched or something... One Carb Top is slightly damaged from previous owner trying to use a set of pliers to get it off So I dont think that one is gettng a tight seal...

 

The carb top not sealing is bad news... I would get a tors removal kit from toomey. Replace those carb tops before you ride other wise you could be doing another topend really soon.

 

Figured as much ...
The TORS has already been moved...
I think I am just going to get new Carbs
Mikuni ? Keihin ? any suggestions ??

Thanks

 

I run the Mikuni 28mm flatslides. They are great. Much better throttle response and bottom end.
