gas in crankcase, what does that mess up?

Post by ssridesred » Tue Mar 03, 2009 12:06 pm

So I go to start my KLR after a couple months and find in the process of trying to get it running my carb is overflowing. The battery is now dead and some time goes by. For some reason I notice that oil level window is solid/full even with the bike on it's kickstand. Sure enough gas is now in my crankcase. I think the float probably just got stuck from crud in the carb. So I did an oil change. When i changed the oil I notice the o-ring on the oil filter cover is now all stretched out from the gas I assume. After getting fresh oil in it I pushed it down a hill and bump started it. It only wanted to run at idle with the choke on, it didn't like the throttle much and died about a block later. I think I need to clean the carb and that should fix that problem. What else should I think about regarding the gas in the crankcase? Are there other o-rings that will need replacing? I was thinking I'll probaby have to keep an eye on the shifter shaft and counter shaft seals. I do have the petcock upgrade, I think my problems started from carb. Any pointers on the crankcase? Steve

Petcock upgrade? Did you bypass your petcock shut off valve? This may be the reason that you have gas in your crankcase and could have created a fire hazard by overflowing fuel. Do you have an inline fuel filter? Clean your carb and I would recommend going back to the vacuum shut off petcock. If your shift shaft seal, and output shaft seal are not leaking, then I wouldn't change them. Just keep an eye out for any leaks.

I did the Big Cee petcock upgrade and always leave it in the on position. Never had a problem with the factory or Big Cee setup. Seems like once I tried to get the bike running is when the gas started to overflow the carb. Seems like the float got stuck. I am not running an inline filter. When I get the carb apart that should tell more of the story. I suppose while I am at it I'd better investigate for fuel in the airbox. Steve

<><><><><><><><><> <><><><><><><><><> Steve, I haven't seen a reply to your question and thought I'd make a comment or two. I think I'd run the engine for a few miles to get it to operating temperature and then do another oil change while the engine is still warm. I'd also make sure the engine was clean and then watch for leaks. I doubt you get any because of the fuel dilution but could be wrong. I would make sure I was turning the fuel off every time I was not running the engine to keep this from happening again. The engine performance issue sounds like you might have a clogged jet or two in the carb. A good cleaning should take care of that. At the same time you might want to check the needle valve to make sure it doesn't have something stuck it in allowing the flooding issue. Might also be worth keeping your battery fully charged. Storing a discharged battery will reduce it's life even if it can be recharged at a later date.
