Keihin FCR 39 on a DRZ400S
Posted 11 September 2005 - 11:30 AM
I ride from sea level to around 2000 feet altitude. Normal temperature is around 40-60 degrees. Of course I will enlarge the air intake when changing the carb.
Can anyone tell me the best jetting for this setup?

you will need the intake manifold,air boot,throttle cables and assorted clamps from a E model.
you to check what jetting it has.most likely pretty stock.
3x3 air box mod

I´ve got two questions:
1. There is a breather hose coming from the crankcase, through a box and to the intake manifold. The "E" manifold I have now does not have a hole for this hose. What should I do with it?
2. The Mikuni I´m replacing did have 2 electrical plugs, 2 pin and 3 pin. The FCR does only have the 3 pin. Can I just leave the 2 pin plug as it is (not connected)?

you plun in the 3 pin connector (tps) and just leave the other unplugged.
