Default Re: 40mph?????

You can optimize the engine as much as you like BUT the stock gearing on most engine kits is too low to allow for high cruising speeds...The cheapest way to make the bike go faster is to install a smaller rear sprocket....I run a Dax 70 with a 36T and and can max out at about 34.4 MPH...if you want sustained cruise over 30 you may want to go even a little higher (smaller sprocket) since at 34 MPH my engine is screaming pretty high....Of course gearing depends on other factors too like rider weight, terrain and altitude above sea lever etc...
Hope this helps you.
