i have an older 110cc lei transformers quad, it ran well for a while then it did a starter motor ( i found this out after trying to jumpstart it and frying all the wiring) i have now replaced everything , BUT the new starter doesnt seem to wind it over fast enough for it to start.... there is a ton of spark but it seems i have recieved a dodgy starter motor and well as it took me 18 months to get aroung to fitting it , its my bad and will have to get another 1..... before that it went like a rocket, i ran it in for 4 tanks of fuel b4 i started giving it hell with my 90 kg plus the weight of whichever child wanted to get on with me... this thing lights the rear tyres in gravel , on grass, you cant keep it str8 in the mud ( much like a dirt track car hehehehehe) and if u keep ur weight over the front it will do circle work on tarmac... i will get her up and running again and have a go at posting some videos from the next time i have her out bush............
