I recently purchased a 1981 yz250, looking for some upgrades to the bike. I’m definitely going to do the race tech suspension. I was looking for a top triple clamp that puts the bars in a better riding position with the rubber mounts looking for more of a stock type look.
2. I’ve heard that a swap can be done to make the bike a digital ignition, swapping to a YZ 85 ignition. Does this help? If so, how? What is needed to get the job done.
Thank you!

Reworking the back shock is a good thing and getting the right springs will do wonders. I have a 81 YZ465 with a fox shock and it was great. Even my modified YZ shocks are way better than stock. It was a fun bike.
Maybe an heavier flywheel from an IT ?? may smooth things out, not a lighter flywheel.
On my bike back in the day the cylinder head was modified by the shop, probably squish and maybe shape.
That with Boysen reeds and is was a strong engine, still mid range.
As for the top triple clamp the 1982 YZ490 was rubber mounted and pointed the bars more upright than back.
The Racetech suspension is a great upgrade, especially in the rear.
I also spent money on upgrading to a twin leading shoe front brake, although i never managed to get it working any better than the stocker!
