Hi I’ve got an Lt80 just put
Ebay top end kit cylinder head & piston
new crank seals
Cleaned exhaust threw
Cleaned Carb thoroughly
New air filter
It turns for ages eventually starts and runs great within 5 minutes of running when it gets hot dies and won’t start until cold again

pulled the top end off and it’s scored the piston was the cause just cheap tat off eBay and replace with better quality parts?
Thanks

 

You need to get your OEM cylinder bored to the next size piston.
I can help you with that and the parts if you'd like. I only use Suzuki parts.

 

Hi thanks for your reply I’ve rebuilt the engine it’s now got 120psi got fuel and spark runs for 5 minutes and dies same as before could this be a stator issue? Thanks

 

Ohm the stator. 173+/- 20%

 

Are you in the UK Lt80?
how much would it be for you to rebore the cylinder and a new piston?
thanks

 

Sorry, not in the UK.
