My friend is tricking out his boy's 2000 LT80 for racing. He sent the engine to Trinity Racing to be modified. When he got it back he followed all the break in procedures. First time on the the track the engine siezed. Turns out that he did not put the carb o-ring on correctly. That's what trinity said caused it. They re built it again put it on the bike, break-in, siezed... this time he noticed that Trinity had missed one case bolt next to the cylinder area on the exhaust side. intsalled that, rebuilt, siezed.... It's bored to I think around 110cc. and this engine in the short time it does run gets so hot that you could cook and egg on it. Using 110oc, Maxima Super M @ 32:1 and plug was chocolate brown----running fat
Does anyone with a lot of knowledge on this bike care to offer some info. Their email is glps@airmail.net.

 

Okay we've got to give credit where it's due. The owner of Trinity contacted my friend and acknowledged that everything that was wrong with the engine is their responsibility. He is having the engine shipped back to his shop where he will personally take charge and make it right. It has extensive damage and it just goes to show that a good establishment isn't necessarilly one that never makes mistakes but one that corrects it's mistakes and stands by it's word. Considering the cost, thats something to be said.

 

my friend had a racing lt80 and his was always breaking to. those lt80s are for play riding, i don't think they can stand the abuse of being tricked for racing.

 

well perhaps your right but this really had nothing to do with racing. This engine wouldn't run five minutes and thats after modifications made by one of the best in the business. Apparently everything that could be done wrong was done wrong when they rebuilt the motor. At this point you have an engine that is no longer an lt80 techinically. The shocks, a-arms, rear-end, exhaust, in-take,carb you name is hi-pro aftermarket. If you see my point the only thing left stock is the seat and the frame. So this no longer a trail bike. Anyway the good news is they will honor their work.

 

Has anyone else had major reliability problems when doing standard mods to the Lt80? I'm in the process of boring, porting, milling, piping, carbing...you know the drill, to my sons 80 (the kid needs more power). Is this thing going to die on the first ride? Who's got a hot 80?

 

well greg called several other shops and they all said "something's not right" and of course offered to fix it for him$ As it turns out every single mistake you can make from the a to z was made when they re-engineered this engine. Everything.(including dropping the jug which cracked it) So like I mentioned they owner of this company has assured greg the it will all be done right and he will personnally make sure of it. We will see. Besides the initial cost. Greg was trying to keep his son in the race for his point standings. So he was overnighting the motor back and forth from texas to california. This guy pledged to reimburse that too. I think a head has rolled at this shop over this but thats here nor there.
