from memory the stock base gaskets are .5mm and have some kind of silicone or rubber coating. just use a few of them and because they have the coating there no need for sealant. My 2mm spacer was made from aluminium. i clamped it between 2 pieces of mdf, drilled the holes and then just cut it with a jigsaw. bit af i file to tidy up and was done.
who does everyone get piston, gasket etc sets from anyone OS that any good and a good price
I get my aluminium base spacers laser cut now but did a lot by hand out of copper originally, jigsaw and drill too .laser is much easier ;) if your base spacers are .5mm just get a few and stack them , one old and 2 new each side will do it the suzuki ones are .25mm ,
Simple buying OS , aftermarket.. Orient Express, and oem... partshark , both have online stores, express post and are reasonable in there pricing , partshark will take longer as they order in after you order, Orient usually have good stock and will let you know if there out of stock
if you do buy pistons, make sure they DON,T have XA type oil rings. they are fucked in every way. I spent $3000 on a zx9 motor only to have it go bang because of these pieces of shit. i was warned but stupidly chose to try em anyway. they say learn from your mistakes... so you can learn from mine.
Got some time today stockbase gaskets are .20mm so I either stack 6 together or I find something to make a spacer out of :D
Bores cleaned up OK, head seems to check out so I will order some bits get it back together and see if I can blow it up :D

I like to try and support local guy's if it is not going to kill me with high cost/bad service ETC so I did a bit of looking at cost over the interweb and a couple of local calls last week.
Most of the local dealers are well above the O/S cost but Flywheels at Alexandria seem to be on the money again(they alway seem to be well below every other Kawasaki dealer ?? makes me wonder about the rest) and I will not save much if any after I factor in freight so I will double check tomorrow when I have some time and if correct will place my order :D. Bit of a trip to get in to Alexandria from Western SkidaKnee but ya get that and last time I was in the area I seen a white unit with an ASF sticker on the back window so I feel at home [8D][8D].I will talk to them about dyno time aswell ya never know
I get a few things of flywheels also, they use Fastway couriers and most items get delivered for about ten bucks extra. A much better option then fighting the Sydney traffic.
Looking at getting a spacer plate cut out of stainless what is the going rate. The people I have spoken to are talking $100 give or take to supply materials and cut
If you know someone who uses a CAD program get them to draw it up, then send the DXF to the cutters. It'll be cheaper that way because the cutter wont have to draw it from scatch.
And NO sharp corners anywhere only radi.
They do a CAD and convert to DXF as part of the price. Sadly don't know anyone that can do it other than them
Really truth be told i think thats a good price for the work thats to be done.
As a paying job i'd change that before laser cutting, thats why i said get a mate cause mates are free :D
Converting to DXF is a mater of clicking the mouse a couple of times so don't be fooled that it's hard work, the time is in drawing the part.
Why stainless ?? aluminium or copper are so much easier to work
+1 for Alooominium.....;)
oh & as it's a base spacer you could cut it by hand pretty easily.
Was thinking about that but I want to get a couple of other bits done ( want to make a new plenum and carb plate)so may get it all done together.
Ben I will give you a call Monday and see what you can do [8D]
Does anyone know what size jets come in the dyno jet stage 1 kit or am I better off having just getting a some straight from kawasaki? Looking at about 150 - 160 main
You shouldn't have to go that big if you have good dynamic boost. Shouldn't have to go much bigger than STD jets
Standard is 200(1 & 4) 210 (2 & 3) going by the manual. Will pull them down again tomorrow and check I think mine has 180 & 190 (can not remember exactly)
The fella I was speaking with is running 150 in all 4 on his turbo zx7 and he is happy and seems to be running clean.
Struggling with this a bit but will work through it
Kawaka jets must have different number system to Suzuki. A 750 suzuki would be about 117.5 mains
As you were

Keep this in mind---> From a Dynojet tech rep:
We are often asked for a "cross reference" sheet that compares our main jets to Mikuni or Keihin. The fact is you cannot directly interchange the jets for a given size. Many things affect fuel flow through a jet of the same orifice size. The entry and exit tapers of our main jets differ from those of other companies. Due to this, the fuel flow changes as a function of velocity through the carburetor venture. This means that two jets of equal orifice size will have a different fuel flow curve relative to intake air speed. At a certain speed the two may flow equally, but a change in velocity changes the flow characteristics. The Dynojet main jet hole size is measured in millimeters. For example, a DJ142 has a 1.42mm hole.

And everythng I am reading is telling me the ZX7 has large main jets to help with the factory emissions system once remove you go smaller and with the turbo Im thinking smaller is the go
