Engine seems to be locked up

Postby daljaz » Tue Jul 05, 2011 6:05 am



My '84 Aspencade with 60,000 miles has been running great...no noises...no overheating..great performance. I parked it after a ride, and the next day it would not turn over. Starter seems to engage, but the engine will not turn. The battery is fully charged and even with a booster starting unit, engine will not turn over. It is full of oil and the oil looks nice and clean. The coolant is at the proper level. Is it possible the timing belt broke upon shutting it down? ( I have no idea when it was changed...I've only had the bike about a year). Does this happen often? Also, if this is the case is there possible engine damage since it was not running? Could there be another cause for lock-up? I know I've asked a lot of questions, but would appreciate any thoughts. Thanks in advance.

Im no expert (by any means) but I have tackled the timing belts and found it easier than I thought. Your assumption is possibly, but you would have heard something out of the ordinary upon shutting the engine off, even if it was a quicker than usual shut off. Pulling the front timing belt covers off is easy to do in order to verify the belts, and if they are intact, you could put a socket on the main and try turning it by hand, it should turn fairly easy........ and while you got the covers off, change the belts! I believe it's recommended every 30,000 miles.

Unless it's fuel injected,don't get nervous just yet.Pull all 4 plugs out and kill the ignition(kill switch)try to crank the engine over again.DO THIS OUTSIDE.It may be hydro locked with gas. :shock:
Sometimes a needle valve sticks and setting will flood the carb and fill one cylinder with gas.When that happens the engine seems to be locked up.
If that's it.crank it a few times to clear it out,let it set a few hours to evaporate the fuel,put the plugs back in and go.Run some sea-foam in the fuel and shut off the gas when parked.

Thanks for all the help with this problem. Virgilmobile was correct. # 1 cylinder was filled with gas causing a hydro-lock. Engine turns freely with plugs removed...gas shot out of # 1 cylinder. Now the problem is fixing the stuck float if that is the culprit.

Great news...My 1100 will (once in a while) hydro lock if i forget to turn off the fuel.Yea,I know,I really need to tend to it.But in the mean time,I just got in the habit of shutting off the gas when it's not running.Maybe I'll look into a automatic electric shutoff valve.

Good tip! I never had this problem. Ironically my son just asked me the other day why the gas needs to be shut off on bikes, ..........I didn't know. Now I know! Thanks for that.

What about a SilverWing vacume controled petcock? Opens the petcock when running by appying vacume to it and closes without.

Good idea,but what are the vacuum requirements?The wing has a port in each manifold,but it pulses from that cylinder.I wonder if it would be enough to keep the valve open or flutter it open and closed?
Do they make an electric one?I'll check.
