So i sold a bike to someone. I put a k star 15mm bing techno boss onto a za-50. The install was perfect flipped clutch nub grinded ring gapped proper timing all that.
She is new to mo-peds. I explained that the bike needs to be broken in take it easy blah blah blah. She takes the bike on a 13 mile ride to and 13 mile ride back with her friend. Bike dies on the way home. Calls me because its running really rough when she gets home.
So heres whats up with it.
I go over and find that her frined has put a o ring infront of the bing to create a better seal?. one of the screws on top of the carb is stripped out and there is a small air leak there. I seal it up. and take care of some other things put in a new kill switch etc.
She changes the exaust pipe and puts allen bolts in to attach it. I get a call again because its weired i go over and find that the gasket and one of the allen bolts is gone and the exaust is loose. The hardware store is closed so i tell her to go buy a new bolt first thing.
The next morning she rides the bike to buy a bolt but cant find one and continues to drive to school with the bike as is. no the bike is running like shit and backfiring. Also not going very fast at all. She buys a allen bolt and puts it in same thing poppy and low speed. I say dont drive the thing anywhere ill come over today.
Before i go see it it seized is there anything else you guys can think of besides maybe a bad condenser. Could that small exaust leak cause the seize. Im also suspect of the gas oil mix. Even though i provided her with all instructions. I have assembeled the same equipment of many bike many times no problems.
