If you read the posts in this thread, you'll see people use various mixing ratios, ranging from 50:1 to 100:1

Sherco recommends 50:1 (2%), this is a "safe" number. I think the majority of users go with a little less oil, resulting in less build up in the exhaust system and no plug fouling.

It depends on the use you are doing with your machine. If you do 100% trial with spending most of the time at idle speed, you could use a ratio of 100:1. If on the opposite, if you do more trail riding, then 50:1 would be more suitable.

I personnally mix at 90:1

Now, since you seem to be looking for exact quantities.

50:1 means 50 parts of fuel for 1 part of oil, so 20ml of oil for 1 litre of fuel.

75:1 = 13.3 ml oil / 1 litre fuel

90:1 = 11.1 ml oil / 1 litre fuel

100:1 = 10 ml oil / 1 litre fuel

etc.

don't know if it is availble over across the pond or not, but Red Line's two-stroke racing oil is the best I have ever used. I have used it in Yamaha TZ-250 road racers, Husky moto-cross and enduro bikes, and our trials bikes.

It is by far the cleanest burning, best-lubricating oil I have seen. We won the Pikes Peak Hill Climb in 1991 on a 250 Husky running 100:1, and the engine was perfectly clean after three days of testing and racing, with zero carbon build up.

In a properly jetted trials bike at 100:1 the oil is nearly smokless and there is almost no build up of exhaust by-products in the exhaust after a full season. It is a great oil, as are all of the Red Line products.
