Qwestion for the Masses

[Sabre093]

OK here it is i need to know stock tooth count for front and rear spockets..i got a 86 1200 and it's been changed,great for acceleration but for cruising its not good.I bought bike this way and want to change back...3700-4000 rpm @110 kph is to high,2nd qwestion does anyone have a 12 volt accesory hooked up and where did ya mount it...thanks everyone in advance..

If I am looking at my Yamaha service manual correctly..41 tooth rear sprocket and 17 tooth front.

Stock for the early FJ's was 41 rear, later it changed to 40 and then 39.  Front sprocket was 17 for all years.
IF you're getting 110kph @ 3700 its already pretty long gearing.
If you're getting 110kph indicated @ 4000 its pretty close to stock.
If it varies between 3700 and 4000 rpm, you need to inspect your clutch.

You can put an 18 countershaft sprocket to lower it a more, but I don't think you'll find a rear of less than 38.

is your speedo off if your changing the sprockets?

[SlowOldGuy]

No, speedo mechanism is on the front wheel.

Doesn't mean it isn't off anyhow though.  But the gearing won't matter in that case.

You can make it read low in the first gears if you can keep the front in the air though, I suppose that's related to gearing.

Throttle control grasshopper, it's all about throttle control.  Learn to accurately micro-manage the throttle and you won't need to touch the gearing.  There's my input -that and about $1.58 will get you a coffee at Starbucks.
