So my little project was going fine untill the ending, Fitted my stage6 streetrace, Unbolted a 70cc parmakit (Very shocked as last owner didn't say) And fitted my stage6 pro replica, ticks over fine but then as soon as I throttle it just goes nowhere and bogs out, I have tryed upjetting, Clutch springs, 4 gram rollers, Even the air screw, What else????? Does anyone think it may be the needle needs adjusting? I have a 12mm carb! Thanks
Yeah, I ordered a dellorto 17.5 and getting it booked in next week when it comes but i need it running for now though
It's not breathing through the 12mm carb, remember every stroke needs 40% more air than a 50cc. You could try removing the snorkel to help get more air in. Mine ran with the 12mm but not very well, fitting the 17.5 dellorto transformed the bike but again without snorkel. As an experiment try putting a short reach plug in it may run as the tip is out of the fuel flow and doesn't wet as easy.
