i have a 96cr250 and it runs great. the only thing that is messed up on it is the scilencer is losing the rivets in it. they wobble loose and the back section of it is loose same w/ the front of it. should i buy a new scilencer($85) or get it weld. i like the way my bike runs now so i dont want to change anything. i thought about getting my friend who works in an autobody to weld it up. not shut but to reinforce where it is riveted together. this would be a temporaty fix but could work i think. id take it apart n clean it up real good then have him possibly weld a collar around it and in it where it bolts together? its aluninum(sp?) so welding is tricky. could i possibly get some steel collars and have them weld on? im new to welding and everything about it so just tell me if this is goofy.
