March 14, 201016 yr Managed to get a half hour on the Stormer today.Runs well with the 38mm Amal mk2 on,jetting is close. I had a 390 in and plug was a bit lean,going up to 400 for next time. Starts much easier and pulls well. Airbox is a bit heath/robinson though,used the standard filter and just blanked off the rear of the carb with a square of corugated plastic and the sidepanels block it in.A work in progress I think.
November 10, 201114 yr Andy I used to ride twinshock MX back in the day. Everybody used Castrol R30 or R40 as it was one of only things that was any good at the time. I have never seen it used as gear oil on a 2 stroke, we all used it as pre mix oil at about 20:1, Castrol made gear oil for 2 strokes at the time call Castrolight,which was really light. So most people used that. Could be that the R40 is to thick for your gearbox as I remember it being quite gooey, but ahh the smell (takes me back).
