Up a creek

[KicksonR66]

So I went to cross a creek about 12 to 18" deep hit a big rock and fell. The bike was down maybe 10 seconds, went to restart and nothing buddy had to rescue me.

I have removed the stator cover that had a little moisture, checked for spark with plug out and I do have spark. Put plug back in and can't get it to fire, remove plug again and have spark. Decide to check spark with a plug in head and now I cannot get spark. Bike got wet on Sat so plenty of time to dry out.

Any Ideas?

Thanks

I would suggest to pull the front crankcase drain (on the bottom of the engine under the crankshaft-well forward of the oil drain) and kick it through while that is out, Clean and dry the air filter, new spark plug, drain the carb float bowl and either stand it on it's tail to drain pipe well or pull the pipe since you're back home. More than likely you still have water in the engine even though it's been 2-3 days. DON'T FORGET TO PUT THE CRANKCASE DRAIN BACK IN AFTER YOU REMOVE IT ! It would be a perfect time to change the oil also........Good luck

Thanks Fred, will do and will let you know, it may take a day or two before I can get to it. I see your in NW AR, I am near Moyers, OK in the mountains. I suspect our terrain is similar and was wondering what is your rear tire of choice? (Sorry for going off topic)

Thanks again,

Hate to tell you this, but if you have creek water sitting in the lower end for a few days your almost certainly looking at main bearing failure in the very near future.

I could have went all day without you telling me that......5oz of water came out crankcase drain, oil looked good. Your certain of bearing failure?

Update: Pulled pipe, water as well.....oil looks good no separation after approx 45 min.

Glenn is probably right, 5 ozs of water in the crankcase is a very humid environment, not to mention the 'unfiltered' creek water. IF there was terrifc oiling going on you might get lucky though- at this point you have 2 choices- tear it down and look or fire it up and LISTEN CAREFULLY---ALL THE TIME !!! If they start rumbling then get them fixed.

I run any stiff desert rated knobby with TuBliss inserts at 6-8 psi. Tried the trials tire route and it just didn't suit me
