January 25, 201511 yr Hi there As the question says ! I've got a sprite with 37a engine and my son has a James with 8e engine Is modern 2 stroke ok ? If so what ratio Cheers John
January 25, 201511 yr Hi John, I run my 8e,s on racing castor @ 80 or 100 to one, besides the lovely smell, my engines last as long as anyone elses. In the Yamaha ty250 manual, Yam recommend Castrol R40 at 80 to 1 and the modern castors are far superior, so give it a try. Trev.

January 27, 201511 yr Hi folks Re using Aspen fuel: I am rebuilding an old racing Bantam for fast (!) road work. As it has a fibreglass tank I wanted to stay away from modern fuels so asked Aspen for their recommendation. Their reply was to use Aspen4 (4 stroke mix) 'to give storage stabile fuel and the other benefits, then add 2stroke oil recommended for the Bantam.'
