Hello,
i am wondering if there are any known race chain conversions for the FZR400 3EN (1989). The service manual mentions 428 chain and 19/55 front rear. If one goes to 520 (which should be fine even for a tuned motor) whats the best sprocket combo and how many links are required (roughly).
Also anyone knows renhal codes for the sprcokets that fit on the FZR400 1989? Are the same with the FZR600 3HE?

Many thanks,

You could just order them through BandC Express they're very helpful.

the conbination of sprocket sizes depends on where you intend to run it. 14/46 seems to be a decent compromise of acceleration and top end.

Thanks, thats what I was looking as I have several spare race 520 chains from the R1.
Btw that sounds familiar as the FZR600 3HE .

Regards,

Sorry about this extra post but what is the right code for the front 3EN1?

322 ot 321 (FZR600) or 287?

I know the rear is 175-520-xxHA.

But no idea whats the right front. 321-520-xx fits FZR600, 287-520-xx is for 3TJ? and also 322? But I have no idea which is the right one for the FZR400 1989 3EN1.

Regards,

I've got a -1 front for a 520 3en2 somewhere

Right then - 385U-520-14P is the code on my sproket I think that's -1 from standard

the 14 in that number should be the number of teeth on the sprocket.you should be able to just change the 14 to what ever teeth number you require, the first numbers are the model specific ones.
