250-500cc 11' WR300 clutch friction disc thickness needed???

Having issue's with the Z-start pro I installed a couple months ago. I've mic'd all the stuff that came from Rekluse and everything is correct to their instructions and verbal over the phone. I only had 5 rides on the bike when I installed it so I figured the clutch pack wouldn't be the problem but figured I'd mic it as well but can't seem to find that info in the owners manual. Greatly appriciate any help.

You'll have to download the parts manual to get that info ... sorry bloke l don't own a WR300.
