Castrol power 1 2T

[foxy]

I know oil choices can be a bit of a minefield but I would like to hear a few opinions on what I should do.....I only just recently bought a 1981 350LC which came with a full tank of motul 2t and it is close to being empty, do I carry on with motul or use Castrol power 1 2T as I have a small stash of it that I use on my little X5, of which I have had no problems ? And if so would you drain the system completely and add the Castrol?

Use anything that's at least JASO FC rated. Stop worrying and just enjoy your bike.

I provide a full restoration service on the pumps, and have probably done the majority of pumps on here, worldwide too. The majority of all those hadn't had a reshim since the last time they were in a dealers! So I'd be more concerned if anything is coming out of the pump, as opposed to who makes the oil.

It's like asking, what's the best air to use in perished tyres?

Cheers arrow, I have read many of your posts which are very informative and I have checked my pump with my feeler blades and on low stroke the gap is bang on and the mark on the spool aligns with carb dots in the windows, also 2T oil consumption appears to be ok, Castrol power 1 is JASO FD rated so I take it FD is better than FC

Correct, JASO FD is a higher specification than FC, but only in cleanliness. The lubrication specification is the same. It may be higher in the latter criteria. but it's not required to be so, according to the specification.

Cheers for that arrow, I forgot to mention the clearance was 0-25 as per one of your older posts and has yellow paint on the pump which I believe makes it a 350 pump the only fault I found with the pump is that someone had fitted the cable OVER the return spring of which you have also mentioned 👍
