Could someone tell me what the standard size bore the lt 80 has?
Cheers
Jason

 

50mm

 

Thanks for that
Strange thing- barrel bored to 51.5,standard size=50 so i should have needed a 1.50 oversize piston, had this fitted and was far too small,ended up with a 2.50 oversize piston to fit.
Was running fine- no spark now :-(

 

2.0 prolly (52mm)....the big bore pistons are 54 and 54.5 which you don't want IMO.
Forget the ground wire to the motor?

 

was def bored to 51.5, and its 2.5 oversize piston that matches
Maybe the uk models have 49mm bore?


Got the spark back, was a faulty stator coil, got one from similair and rigged it up

Seems to be going great now :-) kids happy anyway

Thanks for all your replys to my questions jack, its much apprecieted
