It is best you could tell us how many RPM your bike does at top speed, what your top speed is, and what cc your engine is (a 50, 150, 200, or 250cc?)
If you don't have a tach, you could get one for $15 from ebay, a battery powered, with only one wire that needs to be wrapped around the sparkplug wire; easy on install, but a necessary tool for diagnostics if the bike itself doesn't have a tachometer on board!
