MX 250 Resto-Mod to Scrambler Style #1
As mentioned in my introduction post under the "And just who do you think you are?" thread, I pulled this bike out of the woods and am looking to restore it/ update the styling into something that resembles a scrambler, or at least more like the DT enduro bikes.
Here are pictures of the disassembled frame:



A few surface rust spots, but the thing is solid.

I will be adding pictures as I go.

For now, can anyone tell me a good way to adjust the twin shocks in the back? I don't know if they are just locked up, or because they are set to the most compressed setting that they barely budge.

Thanks,
Michael

Forks look mighty nice through the exposed slider areas! Tank looks nice, and not dented, too! Lots of threads here on replacing the seals/fluid in the forks, and lots on getting the rust out of the tank, if it has any rust. Looks like a good skeleton to start with!

Rear shock preload looks set to the softest setting. They also look like they might be from something like a 1000 lb street bike which is likely why they are stiff.

Springs are on the hardest setting [sorry Mark], so let them back, then try to release the spring clips [can be difficult] I grab the top end in the vice 'tightly' & pull hard on the spring to get the clips to drop out. Bottoming out rubber might be in the way so flick it down the shaft a little. Then twirl the shafts to see if revolve straight. Then if any rust give it a clean up best as can so as not to push rust into the seal & shock. Then give them a pump while held vertically. & good luck with all that.

Well actually you’re both right (or wrong) one shock is on the stiffest setting and the other is on the softest

Na--look again i say. Bottom one in the pic is a bit difficult to see but still say its on max--just as the top one in the pic is. I expanded it right up for a good nos. Anyway the distance from the bottom of the shock is a giveaway. Hate being wrong lol--prove me wrong--please don't.

Actually i wonder what shocks they are because originals were reservoir type shocks. These look a bit like TT500 XT500 which will be lightly gas pressurised which--if they are--it'll be obvious trying them minus springs as will return under pressure. Might be a bit short for TT XT.

Wow. I guess I need my eyes checked! Was viewing pics on my phone and looked like was on soft. Thanks for the correction Morley! Those still look like heavy street cruiser shocks to me though. Might be wrong about that too though.

Can confirm, both shocks are at the same setting. I just wanted to see if there was a good way to go about moving them to a softer setting.

I pulled the covers off the engine, and the clutch side is in very good condition:



However, the stator/magneto side had water in it, and it was not pretty. This is what the stator looked like after some light wire brushing and replacing the screws:


The magnet is also rusted to the driveshaft, as it wold not budge, even with a puller cranking down on it and some penetrating oil sprayed on the shaft. The oil seal spring basically flaked off from the indicated position while I tried to remove some of the rust:
