Ok new question I am about to put on new rear bearings do I need a press to get them on the right side near the chain it don't seem to want to go on I'm not sure why and thank you aceisback I may do that

 

I've got a 2000 ds650 and it starts great and idles great, but it does not let you open up the throttle. Its like some sort of limiter on the carb and Im not sure how to fix it, anyone have anything that might help? I've owned it for only a few days and i can slowly creep around the yard but that's all the throttle will let me do.
