Re: B50 S*zuki DLS drum brake install

Well, I did finally finish the install of the S*zuki DLS brake after much screwing around. But, the results were more than worth the trouble. The brake is scary good, during my heat race I actually had the rear wheel come up when I grabbed too much brake! :shock: The old B50 did me proud though as I...

Re: B50 S*zuki DLS drum brake install

Hi Tom, It would have been fun having a couple B50's racing together. We never seem to have more than one going at the same time :grin: . I don't remember the exact dimensions of what we removed but we had to shave both the forks and backing plates to make it fit. We did make a new axel but still us...

B50 S*zuki DLS drum brake install

I have been racing my B50 for 7 years and one issue I always had was front brake fade with the original drum. The brake works well but on short tight tracks I would get fade even with better pads. So, a few years ago I purchased a S*zuki dls brake at a local swap meet with hopes of installing it on ...

Re: Broken bearing retaining plate

I don't think the crank ever comes into contact with the retainer plate until it actually fails. The crank bearings are shimmed and there is zero play. Ed built the bottom end both times it failed so I doubt it's an assembly fit issue. I removed the screws that held the bearing plate and under each ...

Re: Broken bearing retaining plate

My theory is the crankshaft flexes putting stress on the bearing transferring it to the plate. Working the plate back and forth eventually breaks the plate.
