BEET Camshafts

[Mori Man]

After a fair bit of going back & forwards finding out about Cams for the ZXR I am happy to add the following about BEET cams.

Would be nice if others can post up about Kent cams and any other make so we can create a data base for users to draw from.

I have confirmed on another thread that static ZX-4 , H & J1 cams are the same as the adjustable SP cams. If you have no intention of dialing them in different from the factory setting then avoid them and stick with the static versions.

The Kit manual never specifies what the F3 cams are - they surely must be different otherwise why swap out the SPs in the first place - I am going to see if I can get an answer from Kawasaki about spec unless you know of anyone who has measued them up in the past and have details ?

When used with a standard or Kit CDI the addition of strenghened valve springs is not required , when dialed in correctly no other adjustments are needed given you are running a BEET system with OEM FCRs with kit settings.

Sod the cam shaft, I want the 441cc high comp pistons!

please, here's my granny, i'll sell her for the pistons!

LOL , my kit is never for sale !

But , if you read about optaining high comp it looks like the H's fair well ! What also amazed me was no mention of Kit pistons when in other text they recommend Kit parts

This has just spured me on for my build and have been looking at the crank cases today for the build I'm hoping for 90ps now

well the dyno chart is showing a good 15% boost from the 441cc piston kit with beet cams. now over here a typical local shop can get 82bhp rwhp from 400cc, so i expect 95 to be achievable, maybe 100rwhp with FI from a zx6 or similar.

I would suspect a race tune would get you up there but don't want my bike ticking over at 2K when sitting at traffic lights

Also wont have BEET cams in - missed out on a set last year so might go on the hunt again
