Bultaco

Looking for an airbox for a M116....1974 Alpina 350....I'm in the USA

Does any Bultaco expert know if the Matador Mk2 Model 16 (4 speed) CYLINDER is the same as the Sherpa T model 10? My Model 16 cylinder has come to the end of its life. I acquired the bike with a 74mm piston and now it needs another rebore. Unfortunately, the commonly used Wiseco piston (that you need to cut 10mm off the inlet side of the skirt) don't come any larger than 74mm. I contacted Wiseco and could make a batch of 12, but that's more than the bike is worth, and I don't have the upfront cash to hold them and try to sell the extras. Also, I struck out on finding a cylinder liner. So..... I have found a Sherpa Model 10 cylinder or jug as some people call it in g…

I took carb off checked an cleaned it all ok taped up split hoses to airbox and inlet swapped plugs but still doing …

Anyone know if the 4 speed Matador 200 has lower transmission gears (geared slower) than the Matador 250 (MK2/Model 16)? I can't find any specifications (trans gear ratios) on either. If yes, are the transmissions interchangeable? Thanks.

Can old Sherpas be registered for road use in the UK? I guess with frame and chassis numbers a logbook can be requested, I have a lighting coil so could easily fit on a set of high/low front and rear/stop lights. Cant imagine an old Sherpa 250 would be great on the road except for short runs to get to the trails but it would save having to trailer it about. Any thoughts on if you can get them road legal or if it's just daft?

Good Evening All, is there anyone that makes Alloy exhaust systems for 199 325 sherpa?

Hello everyone, I have a 73 Bultaco Alpina M 85 with a Amal carb. The bikes motor has been rebuilt & it has the original Amal carb on it which I have rebuilt with all new gaskets, float, & screens. My problem is the tickler will not tic over. I have talked to Hugh’s Bultaco here in the states & he said the new gaskets are thicker & that might be stopping the plunger from pushing on the float. I’m going to remove the cab & inspect the plunger to see if it comes apart. Has anyone ever had this issue before? Because without the bowl flooding over, these bikes are hard to start. Thanks, Colby

Hi all could someone give me the dimensions for the brake drum insert,I believe cast iron pipe is used? TIA.
