bolt on bigger domestic carbs??
been thinking about this so i thought why not see if there is some feedback for demand.crazya posted a pic where i started looking closely at some 42 keihins that were being machined out to 43mm and having the booster tubes removed,that leaves a premade 42mm throttle blade,stock 40mm carbs could be taperbored at the top to port match the f/a base,have the booster bore opened up,and then machine the bottom to accept the 42mm blade.keep the oil injection,keep the stock f/a,use the stock intake ported.if the jetting could be dialed in on a stock setup,you'd be looking at a bolt and go setup.cost wise it wouldn't be cheap,but they made a hell of a difference on the pro,and ask sirhc what bigger carbs did for his slx
