Mikunioz delivery arrived Monday - good service and knowledgeable.

With a fine glass bead and running at about 50 psi I ended up with a slightly shiny surface, free from stains. Not as good as Vapour Blasting but not far off it. Down side is cleaning afterwards - just when you think that you have it all clean out pops another lump of grit.

New main jet, pilot jet, Needle (Suzuki supplied), needle and seat, base gasket, floatbowl screws and O rings (Viton grab kits).

Rather happy with the way they turned out - especially considering the condition beforehand!

Glad you blokes enjoyed the read - get home in a few weeks and there should be the last few bits of the jigsaw puzzle waiting for me.

Home for a bit, plenty of eBay booty kindly collected by SWMBO.

Rivet counters - look away NOW.

Came across a NOS headlight and supports in the US in glorious chrome that I just had to have. My GT is a 9/76 which makes it a B model. They came with black headlight bowl, headlight brackets and unpainted black side covers - bit of a budget model at the end of its production
So I'm going to slightly diverge form 100% authenticity and go with what looks good.

Spent the day on the polisher and finally finished all the cases - very happy with the result!

Could not have been easier!

I was looking at the reproduction valves in eBay, had read mixed reports but then came across a post about the Kawasaki check valves. Part No. 16128-009.

From memory it was $109AUD from the local Kawasaki dealer (4 weeks ex Japan) vs $96AUD delivered from the UK for the eBay valves.

Looking at the new Kawasaki valves against the old Suzuki ones - fairly sure they are the exact same part - Suzuki never listed the valve on its own as a spare.

Fitting was easy - I did follow the instructions form the eBay valves.

Minor backward step......

The splines on the gear change shaft are worn as expected for bike of this age. I have seen a few NOS ones for sale in the past but the vendors all wanted silly money - found this one in Australia for $100.

So.........side cover and clutch back off......am confident that that will be the last time....might even tempt fate and fill up the gearbox with oil!
