    Hello from Dave in Encounter Bay, South Australia

    I thought I'd post an update.. The "replacement" Z1-900 also appears to have some serious issues, although it looks and rides beautifully. Still investigating the source of a vibration that would seem to be crankshaft related. Not happy. The K2 has had a couple of good runs now, and rides...

    Quadlock location CB750K

    Hey all.. Anyone using a Quadlock on a CB750K ?? I'm having trouble finding a good spot for the handlebar mount and wondering how others are mounting them, or using a different mount maybe? Cheers, Dave

    Petcock missing tube

    My K2 also had the main (longer) tube hacksawed off. I replaced the petcock.

    Let's see your CB750

    Recently acquired a new one.. a K6 in Burnt Orange (I think it's called). The K2 is happy with the new companion :) The K6 needs some TLC, it has been parked for a few years, but is cleaning up OK.. Other than the engine, which has been (badly) painted black previously, and flaking now...

    Who is painting their engine ?

    I'd be sure to use a good primer under any paint.. I'm currently dealing with an absolute mess where the engine was painted black (by a previous owner) and now it's all flaking off.. No primer.. Nightmare city..

    Hello from Dave in Encounter Bay, South Australia

    So, an update! Closer inspection of the bike revealed quite a lot of past work that I wasn't happy with, so things got pulled apart, repaired, replaced and polished to my satisfaction. She's not perfect, but does look nice, and yesterday was a test ride which made me VERY happy. A few minor...

    What did you do to your cb750 today???

    Pulled the wheels off, cut the spokes out, and dropped the hubs off for vapour blasting! My K2 appears to have a K0 front hub - are they in demand? Cheers, Dave

    Polishing Aluminum,

    Dremel with wool buffing pads works the best, in my experience.. super easy to keep things in shape..

    Reproduction Fuel Cap Woes - 1972 750K2

    Hi All, I purchased a replacement fuel cap for my 750K2, have run into some fitment issues.. The original cap is on the top.. Does anyone have a cap to hand that they can measure please? I'm measuring between the pins, not centre to centre.. Cheers, Dave

    Sticky Throttle when Caps tightened

    Update - and fixed! This really wasn't making much sense, as it was working perfectly with the old cables before I messed with it.. Ergo - I screwed something up.. AND.. I had.. The return cable at the throttle end had jumped off the nylon handle, which added friction and messed up the...

    Sticky Throttle when Caps tightened

    Thanks guys.. I've re-routed the cables under the coils and through the frame to the carbs, and it is a little better.. I just tried putting a little pressure on the return spring, and the carbs snapped shut instantly. Reading here that the standard spring is a bit heavy for some people, I...

    Sticky Throttle when Caps tightened

    Thanks for your reply... I'll give it a try, but I don't see how that explains the loose/tight slide caps?

    Sticky Throttle when Caps tightened

    Hi.. recently bought a CB750K2 and going through it fixing up some bodgeyness previously inflicted.. Pulled the carbs and cleaned jets, bowls etc (Bowls were clean, 2 idle jets were partially blocked.) While balancing the carbs I noticed the throttle was sticking open, and needed a push to...

    What did you do to your cb750 today???

    Did my first tune in MANY years :) Very happy with how it runs now, huge improvement...

    What did you do to your cb750 today???

    Wow! Those look like they've done a few miles :) I pulled the bowls off mine, and they were good.. couple of idle jets were partially blocked, but easily fixed.. I'm sure with some TLC yours will come up great again!

    What did you do to your cb750 today???

    Pulled the carbs off my 72 K2 to replace the inlet hoses.. what a b^&%d of a job!! They're back on, but not 100% happy, so thinking they'll come off again for a second try..

    Petcock Butchery!

    Yes, I didn't phrase that well.. Bit strange...

    Petcock Butchery!

    I recently bought a CB750K2 which was previously owned and maintained by a supposed Guru of all things CB750.. There was a bit of a leak from the petcock, so I replaced it with a new OEM item.. (no more leak!).. I was rather surprised though, to find the leaking item looked like this (see...

    Nice to meet you! Let's be friends.

    Welcome! Love your bikes!

    First bike tell me anything!

    Personally, after using/testing on racecars I wouldn't use foam filters on anything.. we found that they are NOT good at filtering fine particles at all, and have a tendency to distort under high revs/intake vacuum.
