We are very fortunate to have just purchased a new Gas Gas TXT Boy 50! Wish we were kids again! We're looking for the oil to gas mixture. This manual says the "oil-fuel mixture should be 1,5%". Not real sure what that means. Our 321 uses 100:1, is it possible the 50 may take the same mixture?
That TXT Boy 50 is a sweet little bike. I agree, wish I was small enough to ride one, but at my size, I'd need one for each foot! The "1.5%" premix ratio should be 66:1 if I figure it right. 100:1 would equal a 1% mixture and 2% would equal a 50:1 ratio, with 75:1 right in the middle. Due to design features, friction characteristics and just plain Physics, smaller engines usually require a slightly higher premix ratio to operate at the optimal level. I run a full synthetic oil in my 96' 370 at 80:1 and it works great. Due to the lesser loads on a Trials engine and the excellent design of the Gas-Gas , 100:1 (1%) is recommended but I run a richer mixture based on the fact that I'm just old-fashioned and it makes me feel better.
