Default Re: Typical top speed......

25 to 30 is about average. You didn't say what rear sprocket size you're using. That will impact top speed as well as rider weight and other factors such as carburetor tuning, exhaust style, etc.
The high 30s and even 40s are possible but you'll need to build for those speeds. If the engine is stock, no modifications such as port work, higher compression and expansion chamber exhaust the 25/30 range is about normal.
