This cylinder has already been sleeved. I personally would get a new cylinder with Nicasil plating right away. Get a quality piston like Vertex or Wössner at 0,05mm of play and off you go. On HPP engines one good upgrade is to get the HPP valves &

100$ is awesome-congrats on the buy! However-back in the day those KTMs were known to have serious durability issues. You might need some more dollars to get her up and then to keep her running

I just spent the last days of riding in 2018 down in Italy. It's the nearest track from Switzerland, just about 20 minutes across the border. BUT as it turned out during the night before they had -5 degrees Celsius ( 23 F) and so the ground was bonehard

Yes i got it fixed. As i wrote (and also showed) my german Tuner Mr. Tisberger is a old school techinician and a specialist in doing such work. I'm in Switzerland/Europe too so sending parts out to have them fixed would be time consuming and get too

The tank you have there is for a '88 125 ! That's why it's this high on the sides as it's supposed to make room for the exhaust. Those tanks got made to convert 88s to the newer looking 250 plastics which followed the year after on the 89 model.

Just as mark_swart commented above me to i found it's mostly just the stock spring rates that are way too soft for todays tracks and jumps. I personally don't understand guys that put modern suspension on vintage bikes. You either want a vintage bike

No, they're not available separately. And they are a pain to remove too...there is a o-ring underneath which makes it a real pain to remove them. I had one pair re-anodized as they were too scratched. Those first USD forks need a good service as they ... more »

Here's a copy of the '89 Mugen catalogue. Mugen didn't just offer the famous engine kits but also upgrade kits for suspensions. What most people know are the internal kits for the traditional 43mm forks but they also offered the USD setup complete with

That's the '89 Mugen forks which came with that red-anodized collar and with adjustable rebound I have 3 such Mugen forks fiitted to all my 89s. Big difference to those first stock upsidedown forks...and leaps better than the stock conventional forks.

Yes - on my HPP engines i actually prefer the Tomasin R&D exhaust as it revs a little further up than the Messico. I just like that extra overrev paired to that insane pull up the very top it offers. Next in line would be the Messico which is a great

I have best results with a 38mm Keihin PJ. Huge improvement over the stock 34mm ! I combine it with Mototassinari Vforce3 reedblock and also added this spacer to the ATAC chamber for better low-end. I tried a 38mm PWK Air Striker but it's no better,
