We are putting a Thunder Tiger 75 in a Reactor 46. Engine Fits pretty good in cowling. Couple questions for you folks 1) Will the OS 90 degree inside header pipe work in the Thunder Tiger, Specs seem to be the same 10mm outside diameter, 8 mm inside diameter? 2) How is the best way to entend the needle valve thru the side of the cowling? Have seen pictures of wire type extensions but dont know how they are attached to standard needle valve.

Thanks to any who can help, please send pictures if possible. Bill
