Resurecting a 85 with 457 miles...

scrubby81 · 03-27-2013, 06:45 PM

I just picked up a barn fresh 85 Yamaha maxim 700 with only 457 miles on it. I cleaned all the grime off it that did not blow off in the ride home on the truck. So my idea is to get it going new tires ( org dry rotted to nothing ) run threw the carbs, but what else to look for at? Brakes are good free and not delamating forks are not leaking oil in engine is clean and going to be changed again but is the valve springs ok? timing chain ? ran a bore scope down it and cylinders are very clean no rust! Looking for tips hints or just tell me what to do lol thanks y'all

New battery, clean the carbs, fresh gas, oil change, and I bet you could ride the wheels off it with not a whole lot of work.

would only add a brake flush to that list

I would worry about the valvesprings having taken a set, so don't wind it out to redline. Also, it was parked for a reason. Maybe it needs a 500 mile service (valve adjustment on mine), so do more than just put oil and gas in it and ride it. Check the fuel tank for rust, change the fork, shock, and diff oil, and replace any rubber lines on it such as fuel, vacuum, and brake lines. Check the carb boots for cracks and see if they're still pliable. Make sure the air filter is sound; you don't want a "looks good" air filter to disintegrate on first startup and fill the engine with debris. Also, the cylinder bores may be clean, but the rings may be gummed up, so when you do get it rideable, take it easy until it's fully warmed up.

Check your wheel and suspension bearings to make sure they're smooth. They've been sitting in one spot for 20+ years and may have flat spots. Also, make sure the seat leather is still supple before planting your butt on it. It may need some work before trying to use it.

carb boots are good, bearings are checked and repacked, tires are on order carbs are soaking new air filter oil filter on bench, haven't had to change fork oil before ? Pull forks off or leave them on tree and how is this done? Will order new valve springs in the am when parts houses are open just to be sure, think I should get fork seals at same time?
Thanks alot for the input

That's a Maxim "X". It has a version of the engine right out of the old FZ sport bikes. Once it spins up, it rips pretty good. You will have fun with that one. You don't see very many around.

? A maxim X? not sure what that means other than a package or trim level will this change parts that I should have ordered?

Maybe it is not the X version. My memory of the 80's is not good. The X was water-cooled. Sorry for the mis-information.
