350 jug on 250?

Hi All I'm sure this has been covered, but searching hasn't been fruitful. I bought what I thought was a 74mm replacement piston/cylinder for my 250 Monza on eBay, and (shocker) it's not as advertised. The setup is 76mm - which I understand is the size of a narrowcase 350 (right?). I also have a 350...

Re: Bronco 98 v. 125 Pushrods

Well some good news is that I figured out that the pushrods are for the 125 - the bad news is I'm building the 98, which has a different pushrod setup: balls on both ends of longer rods and the socket on rocker arm.

Don't suppose anyone has a spare set of 98 rods/rockers? eBay is slim on 98 stuff.

Re: Bronco 98 v. 125 Pushrods

@Craig - thanks for that, I'm in the Pushrods Yahoo group, but just getting radio silence when I ask about pushrod lengths. @dietz - Sorry, I may not have been clear: my 98 engine came in pieces with a single set of pushrods (intake and exhaust are slightly different lengths) - I'm finding that set ...

More Italians in Seattle

Hi All, Have a herd of little Italians that keep me busy, but now starting on a couple Duc projects. My first single was a 160 Monza Jr, but damned if a little manual-referenced tune-up wasn't all it needed to become my favorited little bike - no deep dive was necessary. But now that I've just butto...

Bronco 98 v. 125 Pushrods

Hi All, I'm having a time getting my pile of 98 Bronco parts into a running bike - I've rebuilt the lower end and gotten everything back together up to the top end. Now, unless something has gone horribly wrong, I'm finding the pushrods are about an inch too short for the rockers! I inherited this p...
