Re: Basket Cases

Re: Basket Cases

You could of at least put a new nut on the torque arm where it bolts to the backing plate David. Or replated the old one. Looks good though! :Bultaco: :Bultaco: :Bultaco: =D> =D> =D>

Re: Basket Cases

You are right David. They are a 187 (250), 188 (350) and the 189 which was a 175cc one. We didn`t see those 175s over here I think. I think that middle one in Johns photos could be the 175.

Re: TY175B piston recommendations?

I can remember a lot of people were recommending the Wosner piston for the TYs a couple of years ago. I know Wiseco goes up to a 2mm oversize for Bultacos. Contact David Lahey as he is the TY Guru on this site. Graham.

Re: Basket Cases

Cool Greg. Although I have to say Oh Poo!!!!!. I am after a 159 or any other later head for a 350 Sherpa T though if anyone has one laying around in their shed. I plan on making a 340cc engine out of parts I have. It will only be a 5 speed though with a 158 gearbox so it won`t have the lower gear ra...

Re: Basket Cases

So Greg sent me a photo of the frame number on this bike so I know the frame is a M182 which is the model after the M158. It does look like a Bing on it which only came on the 350 Sherpa Ts. So it may have a 350 motor in it. Greg that Frontera you rode in the 70s would of been a M215. They were the ...

Re: Basket Cases

David, I have only ever seen one M187 or M188 and it had a fibreglass tank. The English ones had an aluminium tank which the dealers or the importers had to out on them. In Motion have steel tanks for sale now to go on the last Alpinas. They are even painted.
