SUNP0177.JPG Started by machining the outer so the windings just slip on. SUNP0178.JPG And then bored the inner to take the rotor which has left a wafe...

Re: Double the troublezz. AMA style Racecrafters Z1000 and Moriwaki Z1R Turbo.

I meant to ask if there is any residual magnetism in the hub from the old rotor, it having been in close proximity with strong magnets for such a long time?? There's no magnetism at all, even the complete rotors are not magnetic at the internal taper. The hexagonal "star" surrounding the ...

Re: Double the troublezz. AMA style Racecrafters Z1000 and Moriwaki Z1R Turbo.

Now that the rotor hub has had all the cast aluminium removed it's diameter is a few mill too small to accurately center the starter clutch so i've had to come up with this steel spacer cup to make up the difference. SUNP0172.JPG It's a very snug fit and is securely sandwiched between the hub and c...

Re: Charging

Hi Al I was thinking of a kit like this for my 1000r and was wondering if you now know of any changes to the kit supplied by them. thanks I recently bought the same kit from Electrex knowing of the faults and expecting no changes to the flawed design. I wasn't disappointed :roll: They haven't chang...

Yes! Just the same as the crank nose i jigged it on in the lathe.
The stock rotors are never that accurate .

Re: Replacement Head / New Seats?

I've been off line most of the summer and only catching up on post now. I know this tread is going back a bit. If J valves are 1mm shorter than the 1000A or 900 valves, can the J also be shortened upto 1.3mm in a J head or are they tied into the 0.3mm max recommended in the service manual? Yes! the...

Re: Double the troublezz. AMA style Racecrafters Z1000 and Moriwaki Z1R Turbo.

Got the cam timing finished off and dialled in so tackled a little job today that i'd kept putting off because there was good chance it may not work out. I'd bought this Electrex race alt for the turbo build which allows the use of a starter motor and decided i wanted to use it on the Racecrafters ...

Re: Z1100 Z1000 heads barrels

Hi, I'm looking for a top end to fit a Z1100 ST bottom end. Not sure if Z1000J heads and barrels are the same fitment other than cc? Trying to acquire parts as I go but don't want to look for parts that are not compatible. Will also need carbs, cams etc. Cheers, Rob You need to measure the little e...

Still loads more parts to make and mods to do as well as paint and covering the seat though.

Re: Undercut or worn gears?

They are cut like that and show little if any wear.
Any wear will usually start to show up as rounding of the peaks and yours look crisp and sharp.

Re: Undercut or worn gears?

All that a steep angle may do is make shifting a little harder as the gear dogs will be more deeply engaged.
The unitrack has an entirely different gearbox, tooth form, ratios and larger output shaft which needs major modification to fit the early cases.
