[Jimbo in Thailand]

@toncey - Like jkv45 mentioned, I would definitely check/clean/replace the air filter first. And if the engine is running OK otherwise I would also check the engine's compression as the bike may have had 23,000 hard miles put on it by the previous owner. Regarding top speed, I haven't checked mine in a long time, but my 2014 hit a freckle under 100mph (stock exhaust and gearing) and I'm a fairly heavy guy (200 lbs).

Good luck!
