Hi all I am new to. All this so please excuse what might be an obvious question I have been looking at the Puma in issue 17 of Classic Dirt Bike and noticed that the rear hub appears to have the 'brake' on the right hand side. I have just bought a 325 and would like to convert to a LH shift and thought that seemed a better solution than running a cable to the standard hub. Can anyone tell me more like what the hub is off and how much hassle it might be to fit it. Thanks .... Rob

Does someone sell rear sprockets on line? I'm told the wheel is from a 1971 Alpina. Chain size is 428. ID about 5.75, 6 bolts, 3 pins about 8mm, bolt/ pin circle about 6.375, shallow counter bore. The wheel is on a BSA C15 and I'm looking for a big sprocket up near 80 tooth. I could even do the ID and bolt circle machining if sprocket blanks were available in that size.

much help needed. ive just finished my 199A and my front sprocket is leaking. so i changed the seal behind the front sprocket and the o ring and the metal bush. i replaced the sprocket and it was still leaking. it is leaking from the final end drive. so i replaced the seal on the end of the gear shaft. it is still leaking slightly but can you advise that this is normal for bultacos?

I just inspected the clutch on my 199A and found that the clutch plates use no friction material, just steel on steel. They were in pretty good shape so I put it back together with 75wt synthetic gear oil and it works well. I'm just wondering if that is the original type clutch and if there are any special oil recomendations for it. I know you guys will know.

Hi Can anyone advise? I am disappointed that the standard Betor fork dust protectors don't really do their job (yes I fitted new ones!). OK, they they stop the majority of the muck getting in but are not as effective as the current design on my Gas Gas. So I have been searching the internet for 35mm x 47mm dust seals (similar to the Gas Gas)to replace the standard fittings. I know from the pictures that the Spanish Puma bikes use this system so I would appreciate help in finding a supplier. I have tried Pyramid Parts without success. Further, due to the nature of the design does this new type dust seal replace the top seal(leaving only 1 seal per leg)or do I need t…

How much different are the engine power characteristics between the earlier & slightly smaller capacity later Bultaco 250 models. In the Bultaco book the earlier 244cc bikes seem to be around 20/21 bhp, the later 238cc engines 14.1 bhp, very odd that they lost 1/3rd their power when reduced by 6cc's.

My Sherpa has run well for a couple of trials but last weekend decided to 'eat' another piston thrust washer. On stripping down it looks as if I will get away with the bore which is +1.00mm (which I think is the limit) but the piston crown has been damaged and needs to be replaced. I am not clear why it has destroyed the thrust washer. Secondly, the conrod has no up or down play but some sideways play and on one side it looks as if it has been scuffed by the flywheels. Is it worth taking the engine down and having the crank rebuilt and could this be why the thrust washers have been failing. Any advice gratefully received from experienced Bultaco owners.
