I am in (want)/need of a larger carb for an 86 200X.

Hoping to find something about 30 to 32mm and a flat slide.

I can get the new Keihin 30MM 60$ on EBAY.

Cost is not a huge issue, I'd like to find the flat slide but I can't seem to find any models from dirtbike to other that ran one that I can adapt to a 200X.

Any suggestions??

Thanks for any help
