Re: B50 oil pump suppliers?

Are the late 250 and 500 pumps the same? I had some one tell me many years ago that the B44 and B25 pumps had different flow rates due to shell bearings and higher rpm on the 250.

Re: Front Brake Stay/Fork?

I had a old man moment and posted it backwards. It is the early forks the had the rib. I have three stock 1971 250's and 2 spare front ends for them. They all have the "rib". Another set that I have that is the later forks does not have the rib. I will check my stock 1974 TR5T later. At my age, my b...

Re: Front Brake Stay/Fork?

I do not think that the 1971 OLF 250's had the rib on the forks, I think that came on the later models. I was told years ago that was how you could spot the correct forks for the TR5T . " Look for the rib".

Re: B50ss verses B50mx Frame

I think the long bolt that holds the foot pegs on is also bigger. Not sure if they went to a bigger one in 72 or 73. I know the 1973/74 TR5T is bigger then a 1971 T25T. I think they were originally 3/8" and enlarged them to 7/16".

Re: Mystery problem and BP is to blame!

We have had a problem here in the USA with gas, ever since they started mixing 10% ethanol in it. It goes "flat" very fast, I have found any gas that has been sitting for a month or more is suspect. The ethanol suck the moisture out of the air and retains it. Hydroscopic I think is the term.

Re: 1974 Gas tank on Ebay

Did triumph sell a street legal rebadged BSA B50 in 1974 or did they only have the MX model. The MX only had the slim tank on it. So if that is the case then this gas tank would be off the more rare 1974 TR5T. Still not worth $500 USD.
