Hi guys....been a while since I have been on here but need some help.
I have a 1985 atc250r that I restored partially last year. I send the top end to Eric Gorr and had him do a number on it, installed ESR reeds, ESR pipe n muffler, 38mm PWK stryker, new clutch, rebuilt forks, new rear shock, new bearings, tires, rebuilt brakes, durablue extended axle, lonestar anti fade axle lock, lonestar double row axle housing.......did alot to it. It was hell changing the axle..the rear end was totally rusted and fused together. I literally had to cut the carrier out with a cutter one little chunk at a time! Very tedious
Anyway..I was so pleased with my trike after all the hard work...it was a monster. Handled like mad on the flat track and the front end would come up at will, even low in 6th. By far the funnest vehicle I have ever owned. Vowed to never sell it. This season I had planned on powdercoating the frame with fresh Honda Red and refinishing the plastic to complete the trike. Then IT HAPPENED....
My brother was opening it up across the front yard and it locked up and skidded to a stop. I was heartbroken....did I catch a ring...did the tranny lock up...was it the crank???? Well, last weekend I took it apart to find a completely blown up crank. This crank was in pieces...with the main failure being right around the big end bearing!!!!!!!!! There was bearing pins in my exhaust pipe this thing blew up so bad!!! The piston skirt was pancaked but amazingly the cylinder is untouched (thank God). So now, I have the motor off and ready to split the cases and do this baby. Good time to strip the rest and get the powdercoat I guess. My questions are:
Aside from gaskets, crank, bearings, piston and rings is there anything else that might need replaced from such a failure? (like counterbalancer etc...)
What crank/bearings are the best?
Should I replace any other components at this time since I have the motor out?
My cylinder looks untouched..do I need to have it honed before a but a new piston/rings in?
Im gonna get the frame powdercoated...can I drop the front end and rear end off in one piece each to minimize work during the frame stripping?
Thanks a ton guys...this sucks but I know if it was screaming with a beat up old 85 lower end (i suppose) that it is going to be amazing with a new setup.
