Hi guy's I've been fighting this whole jetting deal and now this.My bike was running really rich and fouling the plug (jet black & full of carbon).I rejetted and decided to change my oil.I know that this is not good for oil to smell like gas.I always checked my oil level and it was always good never high or low so how can fuel be getting into my oil.The oil wasn't really dirty only 8-10 hrs max don't know what's going on so maybe you guy's can help.I'm starting to really regret putting on this pipe and jet kit.

Predator-or-prey this is not good or doesnt sound good. I hate to break it to you but you prolly blew a hole in your piston. Bring it to your dealer as soon as possible to get this fixed. Or if you know how check the piston yourself. Sorry for the bad news.

I really hope that it's not that.I started it up after changing the oil and it sounded fine.I've had problems getting it to rev up in 4th and 5th gear,but after I changed the jetting it seemed to be fine.Then when I changed the oil it really smelled like gas I mean a really strong smell.I will call my dealer tomorrow and see what he has to say.

What's funny is that I have the same problem. Haven't touched the engine yet besides the first oil change and I had that same smell. I was actually wondering if it had something to do with the oil type.

I doubt you have a hole in your piston. I dont think it would run for crap if it did. Hey Clears does yours still run fine?

Pred or Prey, you didn't hole the piston. a single cylinder engine won't run with a hole in the piston. Depending on how rich your bike was running what most likely happened is some blow by. I wouldn't worry about it too much, just keep an eye on it.

If it did have a hole in the piston it still could run pretty good.

With mine, it still runs great. So I am really not too worried. Worst case scenario, I have to make it a 580.

If it was running so rich that it fouled the plug like a two stroke I would correct the jetting problem and take it from there. If there was a hole in the piston the bquad probably would not even start and if it did the blow-by would pressurize the crankcase and either blow out the seals and/or fill the airbox with oil. With the amount of excess gas necissary to foul the plug I'm sure that some sneaked past the rings into the oil.

My dealer said basically the same thing.That because the bike was running so rich that some of the excess gas blew by the rings.That to keep an eye on it and if it starts to run bad then they will tear it down and see what the deal is but that it's probably nothing to worry about.Thanks guy's for your speedy replies
