Hey guys first post. I was looking for info on the 1980 XT250. Namely suspension upgrades! Anyone had luck with fork swaps or rear monoshock rebuilds?

TT front forks complete with clamps will help. they a millimeter or two larger but just plain work better. Rear shock complete is the same part number on 'partzilla' but have seen YZ looking rear shock in a TT once but you'd have to be careful because if 'much' longer it'll muck up the rear arm angle & play havoc with chain tension etc. I fitted an "18 rear wheel in mine which i think was from a later single shock TT. If you used a high profile "17 tyre on yours it might help soak up the bumps if you don't pump it up too hard. No easy answer but those shocks used to score up the inside body & let the gas up into the oil & turn them into a Pogo Stick. Did plenty at work in the early "80's but mainly TT's as they're the ones getting beaten up trail riding & club MX etc. You'd soon know if 'that's the case' as will just be 'gas' bouncy at the back rather than feeling controlled if you push down on it. see how ya go.

I wonder if Race Tech can work their magic on both the front and rear. Or is there something on Kedo?

I don't have any guidance on the suspension, but man I really like the bike! I don't remember seeing those, but in a 250 what a great play bike that would be!

Called Race Tech. They are going to rebuild the rear shock for $250! Got a front end of a 1992 RT180. Plan to lace in the front disc eventually. Also want to lace in wider rear rim to fit a 120 rear tire. The swingarm is wide enough to accommodate larger rear wheel with no chain or sprocket adjustment.

Hey um can you guys help with an electrical problem? The previous owner had a LED taillight wired in and it was always wonky... When I hit the footbreak the licence plate light went off instead of the taillight? Sometimes the breaklight would work but not all the time. I thought it was the break light switch but now the taillight does not work at all? Used a volt tester where the braklight switch plugs into the wiring harness and nothing? There are no fuses on the bike so what could be the problem? I know there are issues with running LED's on a 6-amp system. The blinkers are LED as well and they just light up and don't blink. I'm at my whits end.

Hello,

Although this is an old topic, I'd like to introduce new information based on my current TXT250 project.

To begin, the stock monoshock for a 1980-1982 TX250 cannot be rebuilt or recharged. The bump-stop can be replaced by removing the preload-upper eye unit. This is not easy; however, a hardwood vise bushing with a 1/2" bore can be made that will allow the shock shaft to be tightly held so the shock-end can be removed. Use of rock rosin will also be needed.

The monoshock from a TT250 of the same years can be rebuilt. The top seal can be replaced, and the shock can be recharged. Roger Albert in Austin, Texas can do the job. This is a nice upgrade for TX250, and the rear suspension will have more travel. Both the TT and XT monoshock springs are way too soft. Use a RED spring for a 1979 YZ125f with a 1/2" aluminum spacer. This is a stout solution to the bottoming out issue.

If you use a TT250 monoshock on an XT, it would be best to change the front fork to that of a TT250 or something similar. Air caps can help the TT250 fork springs.

Attached are a few photos that might be helpful.
