Re: Mk2 twinshock swingarm options

Just go for the same angle to keep it simple. Laying the shocks will soften the back end but give slightly more travel so spring rate or preload may need adjustment There's lots of variables though depending on where the bottom mounts are and length of the replacement arm. Most modern twin shock arm...

What if I want to use the standard top mounts?

Gus

If the S/A shock mounts are wider than mounts on the frame you can buy or get made some screw on extensions for the original top shock mounts.

Gus


To do it with accurately you need a drilling/welding jig that triangulates off the s/a pivot and s/a shock mounts.

Re: Frame number damaged

It's no big deal. Legally it's your bike and you aren't doing anything shady so just sort it whichever way you want. Just powder over it as is or either re-stamp the number yourself or take it to a dealer who may have the correct font stamps to do it. Just don't involve DVLA unless you want a load o...

Re: Starter clutch swap between year models

Thanks everyone for replying Not sure if i'm explaining correctly but I dont need the rotor as I know they wont fit. What i'm trying to find out is will the later starter clutch from a later model (just the large gear, needle bearing and roller housing and thrust washers) bolt up to my small rotor....

Re: Starter clutch swap between year models

Thanks zed The engine came with a rotor fitted but no starter clutch. There's one on ebay listed as KZ1100 Z1100A Z1000J GPZ1100B1 Shaft 1981-1983 Starter Clutch. Does anyone know if this will fit. Thanks David No! Only 1973 Z1's to around 1979 Z1R D1 kickstart equipped bikes (round cam cover) will...

Re: Starter clutch swap between year models

As long as your thou doesn't have a rotor keyway all the small type rotors and clutches will fit from any Z900 to Z1000.
If it does have a keyway then you must use a keyed rotor as the smaller 8mm bolt can't stop the rotor spinning on it's own.
Clutches are the same on all small rotors.

Re: Z650 refresh...

Five bolt is for the earlier Z900/1015 pressure plate.
You would really be better off sticking an earlier steel basket in there too as they don't break when you put loads of power through them like the ally ones do.

You use a compressor that bolts to the top of the head.
Valve can also be kept from dropping by using compressed air instead of rope.

Re: Skimming Z9 a4 cylinder heads

a 5 thou skim ( 0.0127mm ) is nothing.
Less than the variation in gasket thicknesses.
You have miles of clearance .

Re: Giuliara seat.

Those "Bob The Seat" ones are nice but to my eyes are not quite right being all foam and not having the metal in the back .
They look a little too rounded and not as sharp and tight as the original especially the profile where the actual seat meets the hump.
