    Tightened springs dont increase compression - what they can do is reduce valve bounce/float at top end which means the engine will rev higher without loosing power - the tradeoff is possibly higher mechanical wear.

    An example is the engine used in the Humber Sceptre and the Hillman Minx. Identical engines apart from the head. The Sceptre used a high output alum head with stronger valve springs so could rev to almost 6k rpm where the Minx motor with a standard steel head would only manage 5k before things started going floaty or in interferance type designs going bashy into important parts of the engine.

    In smaller engines the easiest way of raising compression is to skim the cylinder (much like skimming a cylinder head on a car motor). This will give you a little more power but care has to be taken or piston will say hello to sparkplug with nasty side effects...

    yes i'd say your correct, I guess i don't know how to properly explain, but the point which you made where the troque is carried to a higher rpm is exactly it!!

    you would need to check a local go-kart shop; its off a 144cc honda; the jet is a little bigger to feed the motor more fuel; the stock gxh 50 is ok; but this one give a tad more :)..
