Hey guys, My banshee started making a growling sound last ride, you can hear it at idle and gets louder with rpm, definitely a bearing and my guess is one of the crank bearings are on the way out, as it’s a 2002 model and still has stock bearings. And I’d like to fix the issue before it ruins something else. I’m running a cheetah a cub 400 that I had kevin hurr do a mid range dune port on, running single 38mm carb, Paul turner mids, cool head, lockout, and been using on stock crank for years with no issues. Really happy with my setup for the riding I do, and I’ve been really easy on the bike so the crank has never slipped out of phase, still runs great just has a growling noise. years back when I put the cub 400 cylinder on I didn’t weld the crank either. Still has great compression as well…. My question is, what is the best course of action here? Replace the whole crank assembly,? or just do the crank bearings and weld my stock crank up? what brand for aftermarket crank and bearings would you all recommend?
I’ve had all kind of engines apart before but never my banshees (I have 2, one for the wife). They always just work and never let me down so other then top end, I have been into the lower yet . Is there a good how to teardown? Or link to oem service manual.
Looking to spend 500$ or so, all suggestions are appreciated. Thanks for the help
