Suzuki 2 Strokes

anything i should know about installation? i have new exhaust gaskets and am planning on using studs and acorn nuts instead of bolts to attach flanges. i cant wait! then all i have to do is install radiator and coolant lines and im ready for an initial startup after my ground up restoration!

ive installed the carbs also with 117.5 mains and needle clips 2nd to bottom groove, pods, timing is set. im kinda nervous. i have lots and lots of money and time into this project.

oh, anyone know what the idle air mixture screws should be started at on the 74 mikunis. i see some models it says 3/4 turn out and others 1 1/2 and others 1/4?

3/4 Look in the general info and specs sticky.

And remember that on a BS40 carb it isn't an air screw of course. Out allows more fuel and in restricts fuel (not air).

Easy way to remember it is if the screw is on the filter side, it's an air screw and if it's on the motor side, it's fuel.

And don't forget that most riding is done at part throttle so make sure it's not too lean at 1/4 to 3/4 at low to mid revs when the needle jet and needle are the main event.

I have had Jemcos on three different bikes, and never had to do more than increase the main jet by one or two sizes.
