just bought a 2001 rev3 beta any body tell me what mixture best to run it at think man before ran it at 50/1 on pj1 fully synthetic

Ran all my Beta's on 75:1 on full synthetic oil.

50:1 is a bit too much oil :)

Stay with the gallons Charlie they switched us to litres and now we pay about the same per litre as you do for a gallon.

I'm like Charlie, the drug store gave me a little 4 oz. cough syrup bottle that's perfect for mixing. Most of the time I only go to 2 gallons though and leave room for sloshing to help mix it. So I run richer than some, but my son's on a Rookie and it tends to get it's, um ti ah well lets see here, oh, it's get's run at a higher RPM more often than my bike does.

Lampkins recommend 70:1 PJ1 semi synthetic we have used this for the past 4 years on 4 new betas never had a problem. :)

We too run our Betas at 70-1 (50-1 while running in) on Silkolene semi-synthetic pre-mix, I know loads of you run with fully synthetic oils but my understanding of it is that a trials bike does not run at a high enough rpm to maintain a sufficiently stable engine temperature to enable a fully synthetic oil to do its job properly.

Carb setup as important as oil mix
