A friend of mine broke his bike's (Duc 749) engine by the book. Last week he let her loose for bout half an hour. I heard him miss a couple gears and hit the rev limiter another couple time ... but noting criminal.

Latter in the day the bike would not iddle and would die at stop lights. The dealer says he fried the engine. The bike is under guarantee but they making a big fuss saying he may not be covered because he "abused" the bike!?!?! Compresion is less than 40 in one of the pistons.

I've raced cars for a while and have been riding bikes for years now ... and never have seen someone fry an engine that fast unless something failed; specially a new one. Any thoughts?

If you ask me there was something going on on the engine.

 

sounds like he doesnt know how to ride and abused the **** out of it. IMO....why should the stealer pay for a engine he messed up?

 

something internally wrong for the motor to crap out like that. if he had no oil and water in it and was dinging it off the rev limiter and riding the red line for miles then i would say he was abuseing it.

 

Sounds like a defective engine. aslong as there is oil in it(most ducati's don't use water), you can't destroy a new engine in that time frame IMHO. All the motorcycle mag take bikes with less than 100 miles on them, run the **** out of them at the strip and track and they have never had a problem like this.

 

40 psi sucks. If the mileage meets manufacture standards on break in like you mentioned, there should not be a prob.

 

Even if he did race the bike, thats what a warranty is for, to fix it. Otherwise what is the point of having one.

 

its a ducati though, all *** backwards.

 

He finally got the bike back. Apparently he got defective rings in one cylinder (?!?!?). Bike was fixed under warranty and he is working on getting an additional 2-years guaranty on the engine.

Thanks for your answers. The service manager acknowledged that frying an engine with proper lubrication is really really hard.

 

thats cool, glad he got it worked out. hope he gets the warranty deal too.

 

tell your m8 the best thing he can do is dump the crappy ducati and get a real bike lol i suggest a ninja 636 or if he is brave enoughth zx10r [sm=goodidea.gif]..........
