My RM rattles!!

[micah1234]

I was riding my 90 rm125 the other day and i was jumping it then i it just started to rattle. so i rode it back to my trailer and it rattles the whole way until u get to power band but once im in power band the rattling stops. and the motor always vibrates/shakes like crazy. So i took the side cover off and i found a bolt in the water pump, so it had to of went through my radiator hose into it, so i took it out put everything back together and it still does it. If you have any suggestions that would be great. thanks alot

If you took off the right side engine cover and found a bolt in the water pump I don't believe it came through the hose. It sounds like the bolt that holds the impeller on the shaft came loose and was ratteling under the water pump cover. You might want to also check the flywheel and make sure nothing under that cover came loose.

If you installed a new clutch did you remove the basket for any reason? If so make sure the nut on the center of the hub is still torqued and has not come off.
