Re: How many OIF 250's and 500's were made

The 250's used to be common around here. Mostly ridden in the woods or combination of woods road. We had a lot of BSA dealers at the time and a few Triumph dealers. I used to be able to picked up a complete 250 for about $50.00. It was a sure thing that the main bearing would be spun and 2nd gear wo...

Re: How many OIF 250's and 500's were made

I was surprised to see that many 250's, considering they were a one year only model. What is amazing is how many are still around after all of these decades.

How many OIF 250's and 500's were made

How many of the OIF 250's and B50's were produced. I know that the 250 BSA/Triumph were only made for one year and I think they only sold the B50 up until 1972. Then there were the 1973 &1974 500's that were sold as Triumph's. It seems that there are still a lot around considering that they have bee...

The temp going back to the tank is useful but not the whole story. http://www.nortons.dk/doc/lubricants.pdf In summary if you have a hot spot in an engine such as next to the exhaust valve then oil that passes through this can be degraded quickly and it never recovers.

Re: oil volume

Be careful that you also do not lose some cooling capacity . Less oil and smaller tank = less fluid to help cool the engine and less surface area. Trials bikes tend to go slow so they do not have the benefit of speed induced airflow across the engine.
