thinking back to your stuck pilot jet , I have 2 suggestions Both unfortunately involve pulling the carbs off and separating the carbs ( be careful you don't drop the 2 ball bearings on the choke slider bar) Once you have a stripped down No. 3 carb body in your hand, drop it into boiling water for 5...

I find that sometimes if you blow carb cleaner thru a pilot system, it won't clear the block because, going from the rear of the carb to the tiny hole in the carb throat just on the inside side of the slide, the channel get smaller so you're blowing an obstruction down a narrowing tube. I've found t...

I suppose it depends on what kind of restoration you plan to do - if you are entering contours, or just making it pretty good, to please yourself.
No harm in phoning Z power to see what they can do for you - they're very helpful in all Zeddish matters

Look at Z-power's website for your bike and search "stickers"

Tyre pressures make a surprising difference to how the handling feels- Back in the day I used 32 front and 36 back with the tyres of the time, but modern tyres seem to need 34-36 front and 40-42 rear - if your using worn but "modern" tyres, and the pressures you used to use in the 1980s, t...

Maybe the needle positions needs moved a notch ( carbs out job tho' - sorry) - do a plug chop at 1/4 -1/2 throttle open to see what the midrange mixture is looking like. Easy to tell if you have an air leak - some Easystart or other flammable spray eg carb cleaner , sprayed around the back of the en...

I suppose you would stick it there because it was the right size. ( and you had a quirky sense of humour. I agree its probably to tidy up the head after removing the anti- smog/ US spec/ PAIRS paraphernalia that we don't need in the UK

Very nice, might see you on the road this summer.

A leak in the exhaust would cause a backfire on the over-run , not a backfire under load. Burnt valve seats would give low compression - worth checking that.

Green and black is usually Earth for Kawasaki I think

Backfiring sometimes is caused by a hole in the exhaust. Have a quick check there while engine idling. What kind of exhaust have you on it? If its a 4 into 4 you can put a hand on each pipe end while it backfires and see which cylinder is doing it.That might localise it to 1 cylinder. ( suggesting s...

At the bottom of the choke pickup pipe, there seems to be a small length of brass pipe with the tiny hole in the centre - probably a push fit into the pickup pipe. I guess it restricts flow. Over time it may have corroded/ loosened/ fallen out (as opposed to previous owners drilling them out.) So re...

its an old post sorry brother
