[TR] Fuel

[Bob Labuz]

Bob,

If you are worried about the exhaust valves, you can get your local 
engine shop to install hardened valve seats. It is not expensive. Bit of 
a chore to remove and install the head but it is worth it.

Others who have the stock valve seats have said they have seen no wear 
with the unleaded gas.

In my area, the only alcohol free gas is the 91 premium. At least two 
companies have it at their pumps. I have been using it for over 4 years. 
All my Triumphs sit for 6 months during winter, and all I do is put some 
Stabil in on the last ride. Never had a problem with bad gas in the Spring.

And as Jonmac says, you may have to adjust your timing.
