I have 15,16,17, and a 19 front sprocket or I could swap the gearbox to li 150 or sx200/tv175 . would like to try the pacemaker gearbox though.

Re: which type of gear oil?

This is a fresh build and no dealers involved. I was presuming that because the clutch plates are from an aprilia that I should use the same oil as used in them.

which type of gear oil?

Using a rocho 6 plate clutch and need to know what type of gear oil to use, was thinking either sae10/40 engine or a light 75/80 gear oil as this is what's used in an aprilia rs125 which the clutch corks come from ?. Cheers Simon
