Yes they work and store pre-mixed fuel, so when you get on the gas it is just waiting.
A dremel is the way to go....according to most racing sanctions you cant powerport but you can blueprint and clean-up the engine to produce cleaner power.....thanks man yeah i think i will as it does seem a ot of work the guy at polini says that if i get a 40ccc then i can race in two clarssis with two carb set ups is this right? or a lot of work? and also if you could help im going to buy tools tomoz any idears whatwould be a good idear im geting a dremal as a start?
Blueprint is to finetune for velocity and flow by matching ports or reducing flow angles which cause turbulence.....Things may fit together but with the right blueprinting those fit together parts will be alot more better than just assembling alone like the bike manufacturs below the $3500 bike price range do......im not sure but i said i would like to go for the 50cc and he said at the momunt theres not meany people raceing in that clarss in the uk and scottland he said go for the 40cc and two carb set ups then race in two clarsses im guessing with the gp6 is a 17.5 i think but not sure and then a 19mm .................
and yes ill get one tomorrow also when you say blue print a engine what do you mean like pollish it up in side? might as well as im doing a rebild and also any idears of anything eles? and also the fly weel can i maybe drill a cupal holes in it to make it lighter however its like the size of a a 40cc piston in half lol any idears? its heavy as hell but is that to balince the engine? any hellp?
