Engine Kits

Motopsychos505 offers anywhere from just an engine to specialized kits made for speed. Don't see a kit you like? Then start with the BTB (basic kit) and then add the upgrades you are looking for under Upgrades & Parts.

 

We have the Highest Quality Engine Kits available! The most important part of any kit is the crankshaft and our “BE40 Cranks” are better balanced “one piece” cranks. Guaranteed to give you more power, less vibration and less maintenance issues.

– Better balanced crank (machined one piece sides, not bolt on   weights)
– Better carburetor (speed carburetor with better air & fuel intake than stock)
– Better chain (415H for less maintenance)
– Better drive sprocket (41t for faster cruising speed than 44t)
– Better chain guide (4 bolt for stronger support)
