Gearing up/down - Your friends the Sprockets

[Pat Conlon]

Yep, 18-40 works for me

I was 18/38 with 180 tire with no problem but to me it felt a bit high so last winter I changed to 17/38 and like it better. 18/40 should be about the same overall. I like to run at 4-5000 RPM on the freeway and that last two tankfuls that I checked the mileage it was 45 and 49 MPG but that was with the FJ speedo reading and I know it is a little off.

The standard gearing on mine is 17/39, when fitting the gixxer wheel with a 170 tyre, I put a 38 tooth sprocket on to keep the gearing about the same as before. Good acceleration and comfortable cruising, 110 kms/70 mph is about 4000 rpm with a ton of torque there for overtaking.

Just some of my observations on this subject.

My '91 started out stock with 17/40 combo on stock 150/80 16 rubber.
I next went to 18" OEM Genesis rear wheel with same sprockets on 160/70 18 rubber.
Then came the swap to the FZ1 rear end with 180/55 17 rubber and 18/38 sprockets. The General on his stock '93 could easily out accelerate me with this combo.
I have since gone to 18/43 combo and I feel that the acceleration is back to what it was stock.

I have not noticed any major change in MPG figures with any of these changes..... my bike has always been able to make at 350 kms per tank and still have some to spare (ie I've never run out of fuel - touch wood).

Engine is still stock (closing in on 150000 kms) with he exception of FP jets and needles/tubes, UNI filters and Dyna 2000 ignition and Dyna coils.
