I have some of them, if you can't find any around.  Where ever you are.

Weymouth, are the manifolds you have in good condition? If the condition and cost is ok I'll take them off your hands. Email me - jwitt85@gmail.com

My Third permanent bike is the 89 FJ12 - nice and fast
Forth bike 89 FJ12 my totally standard workhorse
81 GPZ1100 hybrid - what a bike, built to sell but I can't part with it

Mark, yes you are right, its time I read the section about clutch improvements. I assume you are talking about changing the clutch spring plate setup for an APE spring and hub type?.

I'll be going on a sunday morning run tomorrow, I'll let you guys know if the fuel economy improved (with some luck).

to increase your spring pressure simply add another stock style spring on top of the one already there. oddly enough the clutch spring for a fjr1300 is the same as the fj1200 only less expensive.

Mark, thanks for that information, sounds like an inexpensive fix.

Thankyou for that information, I have replaced my manifolds with the 36Y, and the bike goes like the clappers (especially after the restrictions).
