    Have an 86 ZL600A engine to rebuild and noticed the Cam cover is different to the ZL400, having 2 vented box structures attached to either side, what r these for, pollution control ?

    Plus any chance of ever getting a ZL 600 microfiche parts list?

    Also on road tests, i generally found any USA stuff generally is listed as having less Bhp than model imported here in Europe but particularly the UK.

    ZL 600B regularly lists as 60 Bhp, but the ZL600 A was rated @ almost 74 bhp1 Neither 398cc engines I have, display this feature!


    Cheers

    Found this site above and just found out the Cam Box cover on mine is off a Califonian model! Now, checking engine number with VIN to see what i have got in my box of bits! Hope the engine if from USA hasn't been "wimperized too much by the EPA!

    Cheers

    Yep!
    Bike imported to UK in 1998, ( forgot ZL600 A never imported here in the UK) only ZL600 B in the 19900s, the Naff-looking model! ZL600 A is of 1986 manufacture, so it obviously started life in California n' ended up in rainy old Britain, poor thing!


    Maybe a silly question, but I guess i can just blank those pollution features off/


    Cheers

    12021 is a Reed valve for crancase fume recirculation (emissions system). When you block off those you need to make sure your crancase is vented. Mine has a small filter off the nipple on the cover on the left side top of trans.

    Okay, thanks, I had read about Californian machines having sealed fuel systems, isn't there a vent on Kawasaki engines too, that goes back into the air-box by a small pipe from the transmission housing at the rear of the engine?

    Those reed-valve boxes do not seem to connect through the Cam cover as at first I thought they might!

    Beware buying "Basket case" bikes. Unpacked the box supposed to have all the cylinder head bits in it & at present camshaft bridges 3 & 9 are missing!

    The crankcase is vented separately under the box so plug the hole in front and manifold nipples.

    Mine has no airbox left, in that case a 2" filter is used for crankcase ventilation.
