1978 38mm Marzocchi's

Does anyone have a good set of fork tubes? I have one that must have a slight bend. I put in new fork seals and can feel a tight spot. Thanks

I have a pair of marzocchis I'll see what size the tubes are today I would sell them as a set of course

Scott if they are 35's or 38's but won't work for Dave I might be interested depending on which length they are.  Thanks!

They look to be 35mm and the length from the top of the tube to the center of the axle hole is 33.5 in they are a little rough but will clean up nice the tubes only have a couple little rust spots size of a pencil tip at the top between the triple clamp area, and the legs will need refinished. you can call me at 937-902-1764 if interested

I have 2-3 sets of 38mm Marzocchi forks with minor pitting above the seal travel area, mostly 79-80 if anyone needs a set. I also have a couple sets of 35mm 76-77 Marzocchi's in similar condition. Mike

When I was younger I took a pair of slightly bent fork tubes to my local H/D, Yamaha, and Penton dealer and asked one of the mechanics in the back if they could be straightened. In ten minutes he was back, the fork tubes were straight and he charged me $20. I was making $2.50 an hour at that time so $20 was a full day's pay.

If your fork tube is binding in the leg at somewhere close to full compression, it's possibly because of a bent tube. You can check to see if the tubes are bent by disassembling the forks. Lay the tubes side by side and hold them together. If they rock when held together, they are bent. A little gap between tube ends, say 0.020 or so should not not matter.

Fork tubes can be easily straightened, all it takes is a couple of v-blocks and a strong press. If you can't find someone to do it locally, mail them to me and I'll straighten them, no charge.

My guess would be a different issue if binding.  Tubes usually bend at the bottom of the lower fork plate, but the part of the tube that slides into the lower leg is usually still straight.  I have found some legs that bind with any tubes.  Try the other tube in the binding slider.  If still binds will need to find and remove area where binding.. i have welded longer rods onto those sandpaper flapper drill wheels. That worked pretty good. Anyone with a press should be able to straighten slightly bent tubes. Just need some V blocks to set them in.  I use to have to do that ALL the time in 76-77 with the 35mm 9 inch travel forks.
