    Yes that’s the reference I used. It can get a bit annal, the chapter on date codes that appear on the actual parts goes on for pages. Must confess that I photographed every dated part during my Z1 resto as there are only a few parts on that bike that are not original/genuine OEM so hopefully it will help the kids make a fortune when they come to…[Read more]

    KK, all good, will go with OEM’s. I think the same bushes were used on other Kawasaki road bikes of the time, particularly the triple two strokes. I think cast iron was used because it is probably cheaper than brass and was a common bearing material as it can be used with a hardened steel shaft due to the coefficient of friction being relatively…[Read more]

    KK, the first NOS bush has arrived and debunks my theory about the material changing in the first year of manfacture. It came wrapped in oily plastic (as in the photo) and then in its own sealed bag with the label. From the type style on the label and the (9J) bottom left hand side, we can determine that this part was made in October 1989, and it…[Read more]

    You got me thinking, as I had expected brass, or even just steel. Went and had a closer look and remembering my high school metal work classes, put it to the grinding wheel – fine short sparks that ‘exploded’ in little bursts after leaving the wheel – pretty sure that’s indicative of cast iron. Have attached photo of granular texture at fracture…[Read more]

    Finally got this sorted, what a mission. Understanding the actual construction of the swing arm bearings obviously helped. I tried driving the inner steel sleeve in one direction but cast bush at that end just moved with the sleeve after shearing off the bush flange and threatened to disappear in to the swing arm. Then tried driving the sleeve…[Read more]

    I have re-read the Service Manual umpteen times and maybe I have misunderstood the construction. Manual says, “pull out the swing arm sleeve” before removing the bushes. Does the “sleeve” accupy the full width of the swing arm, sitting inside the bushes at each end? If this is the case then my “sleeve” is seized in the bushes as it doesn’t want to…[Read more]

    No haven’t tried heating the swing arm so will try that. Battery acid has dribbled all over the swing arm so I have to do some repainting anyway. Will also try the hacksaw cuts. The residual problem is getting some ‘edge’ on the inner end of the bush in order to drive them out. On my Z1 the central collar or sleeve was easily pushed off centre to…[Read more]

    Hi, has any one got any tips for getting the bushes out of each end of the swing arm? I can’t seem to get the central sleeve to move off centre and then get a bar in to drive out the sleeves. Cheers Bevan

    Hi, working through a few little issues with my B1 and wondered if anyone has any experience repairing mufflers. Can’t see the cancer when fitted but once they are off it is a bit obvious. Also has anyone found a good aftermarket alternative which I could fit for everyday riding, then keep the originals as is for dress up only. Cheers Bevan

  • Jon, yours looks pretty tame compared to what I found on stripping my B1. I am stripping it back to the cases and replacing every O ring and gasket. I have heard that oil can leak from the two small plugs, which have O rings on each end, and fit in those holes between the outside two cylinder head bolts. Cheers Bevan

    Hi, will post a couple of photos of my newly arrived B1. Low mileage import from USA that needs a tidy up and full medical to make her a reliable rider. Cheers Bevan

    Hi, Thought I had posted these photos somewhere else but can’t find them so posting here. KZ750B1 import from USA with low miles but needs a bit of work to clean her up and make her a reliable rider. Cheers Bevan

    KK, gotcha on the Add Media, I think it has worked. I have sourced from Z-power before but now tend to use Partzilla out of the USA as freight from UK/Europe to NZ seems to take months at the moment. Will start working my way through the check list on the KZ and see what else I’m likely to need. Cheers Bevan

    KK, I have worked my way from fuel tank (in surprisingly good condition inside but will clean and seal anyway), petcock (need O ring and packing washer), to carbs and found needle settings different for each carb and neither near standard (no.4 groove). Slotted heads of the main jets and pilot jets are a bit mangled so looking to replace these -…[Read more]

    KK, she has arrived and looks pretty original. Even the clutch and brake lever have the crappy old laquer still on that has aged to yellow. Needs a little TLC and a good once over but hopefully have her on the road soon. Do need some consumables but can’t get the “Shop” drop down to work for me. Will try to work out how to add photos. Would like…[Read more]

    Kaptainkwak, thanks for that, definitely interested in a stainless grab rail when they are available. Pretty sure the USA B1 didn’t have a seat strap – can’t see one in the parts catalogue. My ’73 Z1 is also USA model with similar short rear guard and no seat strap. I think I saw a thread (can’t find it again, darn) about the grab rails and…[Read more]

    Coleighf, yes a US import so short rear guard and no seat strap, just like the Z1’s. Low engine number, low mileage and everything looks to be original and unmolested, in the photos. Hope to see it in the flesh tomorrow. Got it to save the miles on my mint ’73 Z1. Cheers Bevan

    My model is the first 1976 model, KZ750B1 with spoke wheels. It has been imported to New Zealand from USA so has the short rear mudguard and no seat strap. Low engine number KZ750BE 000612. Bike and any paperwork is due next week. The history section here has been usefull to highlight a few things I will need to look at – intend giving it a good…[Read more]
