Max 4 rebuild

[wildcard]

Hello All,
Well I have finally started rebuilding the 80s max 4 I have , have the frame out of the tub, rusted real bad . My plan is to blast the frame and scab the sides with some 1/8 flat stock, I believe the added 1/4 of frame width will fit back in the tub ( I hope )I disassembled the T20 ( There was no oil at all in it ) but I believe all inside is ok , got a seal kit and two double groove plungers coming and am sending the bands to transcrafters for relining.
all bearings are 62 mm ( had to cut all off the hollow shafts) so looking for a economical source for those.
The oh 160 ignition is shot, but I have a old 1972 Rupp 440 2stroke twin with a clutch( That according to my 16yr old stepson sounds PISSED OFF when it runs ! ) So I think well go back with it.
The frame is what worries me the most with the amount of rust ( part of the side frames flanges are rusted away.

I guess my biggest concern is throwing money into a money pit with no end in sight.
Sorry for the long rambling post.

Hi, I'm in the same situation. I started rebuilding my 1998 Max 4 back in the spring. Had some bad luck with a business venture and have had no money to invest in our Max 4 project lately. Mine was a tadpole pond and in bad shape but not as bad as yours sounds. I sand blasted the frame and coated with POR-15. Installed new bearings and chains. I need clutches and maybe transmission work. Having to wait on those right now. I think that rebuilding one of these is a good investment because if you get it in good shape it will be worth a decent amount of money. Basic Max 4's sell for 4 to 6 grand on Ebay in decent shape. Good luck.
