WR 400 Clutch issues and questions

Hy everybody,

I present myself. I'm Mik, writing from Italy.

I own a WR400 2001 and I'm very happy with it.

I'm going to race in the Italian Motorally Championship this year.

Let's go to the question.

I got this bike last year.

It has Rekluse Z Start mounted on.

i've disinstalled the Rekluse now because the clutch boss is broken.

Now, I can see this situation.

1. The Rekluse Clutch Boss seems to be a Yamaha Part modified by Rekluse. Somebody can confirm that?

2. Intalling the stock clutch i see a little wear on the push rod and on the actuator. I have to install a 1/16 shim in order to get the correct tension. I see that Many people found a bearing ball. Is not my case. Is this a common problem?

3. I see that the 426 clutch is totally different. It has 6 springs and 9 friction plates. Is that clutch compatible with 400? I can buy a complete clutch including basket, boss, plates and pressure plate.

Thanks in advance for your help

Mik
