    To do list:

    Leaky weld on muffler

    Right rear wheel bearing protesting loudly

    Weeping heater core

    Left rear tyre touching the inner wheel tub on hard left turns

    One tappy tappet needs shimming

    Oil pressure switch weeping

    Build a good 5 speed from the two I have in stock and butcher modify the tunnel to fit it 

    Rewire main beams with a relay

    fit electric radiator fan

    fit retractable front seatbelts, and fit rear seatbelts

     

    Otherwise, it starts and runs very well and I’m having fun.

    I have tacit approval from the minister of finance to look for a road bike. In my excitement I dug my riding gear out of the attic and I’m officially a fat bastard. Pants don’t fit no more. Her indoors then suggested I reward myself with a bike once the pants fit again. In the olden days I had a CBR600 then a gsx1100 and finally a Yamaha TDM850. I was beginning to enjoy the upright style of the TDM and being old and fat the appeal is still strong. Got a pine on for a Triumph Tiger 800 and I also enjoyed brother in law’s V Strom 1000 when I hooned it last year. Must be an age thing because up to my late 30’s I had always been derisive of BMWs but now when I see one (particularly a massive boxer twin) I take more than a passing interest…

    My KDX was pissing me off. I thought the swingarm and linkage bearings were seized hence the slow rebound on the shock. It was no better when I replaced all the bearings. It was like riding a hard tail and I was hating it. I thought it was strange that the exhaust blocked access to the compression adjuster so finally I came to the realisation it has the wrong shock! Studied kawasaki parts diagrams and sure enough it has the H model shock which is different and in my case stuffed. I wonder if the exhaust heat cooked something inside the gas reservoir. I sourced a correct shock from a E model and holy wow I’m having fun again! it has completely corrected the tail low stance. I continue to shake my head at how these older bikes end up with so many broken/missing/improvised parts. It’s not that difficult people! Got some more bits and bobs coming to fix other shit. Eldest daughter has taken a liking to the KDX so I’m scheming to get something else.

    edit. Evidence of bike enjoyment:

    Then I took it in for some surgery on the exhaust. I got sick of playing around with it so like a coward I farmed it out to a zorst wizard. There was much choppy chop and a quieter centre muffler was grafted in. Still sounds good but is now bearable to drive. Wizard made multiple angle adjustments to clear the diff and brake bias valve and torque arm.

    One problem to report: Whiff of antifreeze when the heater is on. GROOOAAAN!! Looks like dash out in my future.

    The golf R32 engine has intrigued me, I haven't done any real research, so it's probably a garbage idea for some reason, and is probably not ideal for high rpm, but from a capacity vs physical size, it could be alright...

     

     

    it seems like a likely candidate for a +t conversion, just check out the head gasket surface area between the bores,  and the number of head studs.. (2 things not easily changed on an engine)

    Snap! Have been dreaming of jamming one in the Fiat 1500..

    The KDX is turning out to be a pup, unsurprisingly. Ive done the helicoil twice but the plug keeps winding in on the piss so I can’t get a good seal. Also, the rear shock rebound is incredibly stiff. I can push the suspension down and almost get to the count of 10 before it has rebounded despite backing the adjustment off to zero. She rips pretty good though but it’s not nice enough to spend a heap of $ on.

    I’ve said it before and I’ll say it again, small dirt bike tyres can burn in the sulfurous pits of hell.  Has anyone here invested in a Rabaconda or similar and can comment on usefulness thereof?

    Oh shit. I guess the thread is buggered hence the sealant goo. Yep. Case thread is gone. Anyone ever attempted a helicoil in a bike gearbox in situ? Could be a swarf risk?
