like i say, i have tons of spark..esp with the new Chinese coil, i considered a pw50 coil,but ended up with the qt50 coil, i was gettting a yellowish spark when i 1st got the bike, then i lost all spark..got new coil and got bright blue arc.. i will check,now that its been running for 20 mins on start mode, to ensure its still a pretty blue.
Den 23, i have tried your advice as well, ive had every combo of harness, plug , wire hooked and unhooked in some fashion! it just wont throttle up!
I find its odd, that it does try once in awhile when i ground the black wire from the bike to the control unit, im sure thats telling me something...ugh... no more Yamahas for me! ( as i look on Craigslist at Yamaha scooters) haha
