I posted this at ronronmx.com as well. Just trying to get info.
Me and my friend went trail riding (I guess thats what you would call it) a week or so ago and by the time we were done we noticed oil all over his motor (upper half).
Come to find out, he needs a new cylinder. I don't know the details or much about four strokes but the shop told him its from riding wheelies. Sounds like BS but its got me a little worried. All we did that day was pretty much ride wheelies for 5 hours because we were mostly on roads and there was nothing else to do. My friend is a little excessive in the wheelie department. He goes for like 5 minutes at a time (until he runs out of road) . I don't feel so bad anymore for not being as good as him. lol.
Anyways, is this BS? They said its from the oil not being in the right spot for too long. He rides a RMZ-450 and I ride a CRF-450. I just am happy that nothing happened to mine and I was wondering if it has something to do with the different brands. I was pretty much on one wheel most of the time too.
I've heard this about certain street bikes but I just thought it was a myth. Its got me worried. Actually, its got me missing my 2-stroke!
I just remembered some blurry details.
They said something about the front of the head not getting oil because it was tipped backwards. Somewhere around the valves? Not sure. Again, dont know crap about 4 strokes. Something wore out or cracked and its a part of the cylinder. You need the whole thing I guess.
I dunno.... wierd.
Anybody heard of this?
Thanks in advance.
