Ive got a 5.5 hp Honda Engine from a water pump, plus an unused automatic clutch from a go-kart laying around, I fancy making one, but just dont have the time I might get Junior to make one in his school holidays as a project.
Hardest bike to start I have ever had was a husaberg it was use in single cyclinder racing when we could get it going. We could only start it on car powered rollers with two heavy weights draped over the seat.[/QUOTE]
I broke a kick start lever on mine and had to get a pair of marshalls push me while I dropped the clutch in 3rd, keeping the decompressor in until it started to fire. It kicked back and shot the lever up so hard, it snapped the lever once it hit the stop on the casing!
My teenage son needs an engineering project for school, so his challenge is to design and make a paddock starter. I'm onto something I reckon, child labour and school machine shop time being free.
Basis is to use what I have laying around, which is a 3.5hp (might be a 4.5) Honda engine, centrifugal clutch, go kart rear wheel / tyre. Steel stock I'll buy as it can't be a Scrap heap challenge looking thing.
