Would think the skirt would be too thin to do that, guess you could try turning a groove to take a ring in an worn out piston to see

It's taken them a long time to get the complete change in design philosophy to work
SO... our friends at Ducati had a "trellis" steel frame for years, it worked well... but they couldn't win races any more so they TOTALLY redesigned the frame as a RIGID aluminum thing THAT NO ONE COULD RIDE.OOPS! (There was NO WAY the trellis frame was going to support a 200HP motor. They HAD to do SOMETHING)... and it's taken YEARS to figure out how to make it work (if Ducati hired a frame guy that KNEW aluminum frames BEFORE they redesigned that frame, things might have been different). If Nickey Hayden or Rossi can't make it work, you've done something wrong... then came Casey Stoner (I don't know if they got it fixed or if Stoner was just that GOOD).
Here's another secret: The trellis frame Ducatis weren't particularly FAST, they were just EXCEPTIONALLY EASY to ride. The "ride" inspired confidence. It's easy to be a HERO on a 900SS.
You might notice: I'm into frames.
I grew up drag racing and learned early that ANYONE with half a brain can make horsepower (that's the easy part)... what is HARD is getting that horse power to the ground.
Tires and suspension (and by extension: Frames) are where it's at.
... and DG swing arms... NO... anything DG made was JUNK. Still is.

if it's not too stupid a question, what do the dividers actually do?
cheers, gil.

I only had 2. this was the 1st one in 2015.
I got lucky.

Forgive me for asking... But what's the reason for neutral at lights on these old bikes? Clutch wear?
Quote from: teazer on February 28, 2021, 10:56:11 PMI would never use a crank that has been metal sprayed, have seen the damage caused by it failing. Much better fix is hard chroming then ground to correct size, I have a crank in 1 of my vmx bikes that has been repaired this way which is the method everyone who deals with these particular bikes agrees is the best longterm solution
Have you tried bearing sleeves? They are thin wall shims. You may have to grind down the shaft to clean it up, and in that case things can start to get complicated, but try that.
You may be able to get a new crank from the UK, Europe or Japan.
If it were really irreplacable you could have the crank ground down and metal sprayed and finished ground to size.
Or just try Loctite bearing fit and see how you get on.
