OSSA gearbox

Not vintage in the slightest. But I have a customer’s 2012 OSSA here that was stuck in gear. (I suspect ‘ham footing’ it.) Here are a couple of pictures.

My understanding is generally, Hy-Vo chains don’t have tensioners. But obviously not always since the Honda 650/4 has one (at last the SOHC- not ...

Re: Benelli 750 sei

I have the original rear wheel apart and the hub 1st go through vaporhone. Looks good, but I’ll do one more time. The sprocket carrier is separate on this bike, so I will vaporhone it and of course replace all bearings. The wheel has 2 double row ball bearings, sprocket carrier another 2 single row....

Re: Benelli 750 sei

Front wheel is done (now clean and finish polish)

I’m trueing the spare rear now- just got in the spokes for the original rear and the 4-shoe drum wheel I’m putting on my 250 SS.

Re: Benelli 750 sei

I have not done anything about the discs yet. Might work fine on the lathe- they really won’t take that much I don’t think.
