Re-torque the head when it has fully cooled overnight after the first start.

I'm not sure if its some form of optical illusion but, as Zed9 says the lower inlet cam shell appears distorted or not supported (can be seen in the first/top photo). It almost looks as tough some of the casting is missing? That's the shell location tab which prevents it from spinning in the journa...

Yes! J/GPZ 998cc/1089cc starters are all the same 4 brush type.

The head needs to come off and the valves need tipping at the very least. 0.30mm can be ground off the stem to get you in the 220 ish range but you will soon run out of adjustment and really need to be in the thicker end of the shim range which can be achieved by skimming the collets and retainers a...

What i cant understand is my T pieces are brass, the o rings are set in the grooves and once carbs are fitted to the bracket cant move, so either thats the way they've been made or somethings shrunk which isnt possible, unless their the wrong T pieces for the carbs? If they are brass they are non s...

Keyster kits for the Kawasaki Z and Suzuki GS VM carbs work fine.
I have used Keyster kits intended for the VM28's to replace the entire internals on VM26's i have bored out to 30mm and they have performed faultlessly..

The 0.05mm to 0.10mm clearances are the old specs which were revised to 0.10mm to 0.15mm due to instances of valve seat burning, especially on the exhausts
They should be kept as close as possible to the upper figure of 0.15mm and never let to get below 0.10mm.

Thanks for all the ideas. I have lifted the top off, and all of the valve gaps are between 0.07 and 0.1mm. Valve clearances are on the tight side. The should be 0.10mm minimum and ideally 0.15mm. Whenever they get down to 0.10mm they need the next thinnest shim.. Backfiring and loss of power under ...

Those preload adjusters don't alter the uncompressed length of the forks BUT they do reduce sag by preloading and consequently stiffening the springs so do affect the ride height of the suspension.
They also do make a noticable difference to the front end firmness and resistance to dive.

Up a couple of sizes from stock.
