Last evening I got my ZXR home.
Weather was not so bad that I could have ridden it home, but I decided to play it safe and brought it home in back of a van.

Next morning I took it out in daylight.
Roads too slippery for riding and the front tire is worn out.

The rider’s seat is torn but I fixed it temporarily with black duct tape.

The chequered-flag pattern is painted on the tank and pillion seat cover. I think I leave it like this. Seems that a professional has painted the bike. I got a can of the same paint should there be need for fix.

I have been browsing Haynes workshop manual and I am confused after reading the oil filter removal procedure. It says in the manual that before you an remove the oil filter from crankcase you have to remove also radiator, oil cooler and muffler? What??? Can someone explain this? H2 is different from other ZXR 750’s in the oil filter location but are those other part removals really necessary? Haynes manual does not explain this.

The filter is a cartridge inside the rear of the oil pan. To drop it out, you need to remove the H2 exhaust (which blocks you from getting it out). If you get lucky, you will have an H1 exhaust or aftermarket one which is over to the RHS enough to get it out. Poor design for sure.

Ok thanks for advice, I still haven’t got time to take off the lower fairing to check out the exhaust if it’s blocking the access to the oilpan where the cartridge is located.

I got a second hand rear stand and from local Motonet (car spare parts store that has also accessories for bikes) a pair of bobbins matching the rear stand lifter forks. The left side needs a spacer and a longer bolt but I put the bobbin in place with a spring and plain washer. Works but I need to get right parts to get the bobbin rolling freely.
Anyway now I can remove the wheels and put new tyres on them.
Old tyres have mfg.date of 2010.
Hard as a rock. The tyres I mean.
I took a couple of pics to celebrate the new stand.

I found a longer bolt and a spacer from motorbike store. And it was very cheap too, only 5€ for a pair of 40/60mm bolts, bobbins and a spacer. Very fast delivery too, ordered yesterday and it arrived today. Nice.
In the pic is old short bolt and longer new bolt with spacer. Note:ZXR400 uses the full length spacer, for ZXR750 it has to be shortened to half length. Or just leave it as it is and that’s what I’m gonna do.

Well, I decided to cut the spacer in two halves. Done. When assembling the new parts I found out that the old bobbins had same length as the new bobbins with the shortened spacer.

Nice. So I had to put the two half-spacers on the LH bolt and add two washers to the RH bolt also.
The instructions are wrong at least for H2.

Oh well, now I can lift the Kwacker’s rear to uninstall the wheel and same for the front.
I purchased new tyres complete with installing and balancing. Total cost 320€. I think it’s fair and support the local workshop. The tyres are Michelin Pilot Road 4.
What do you guys think did I make the right choice?
I’m not planning to do any track time, I think :cool: although I live 11 km’s away from Kymiring where hopefully the MotoGP circus arrives
next summer.
New bobbins in pics.

I checked the oil cartridge cover for access if it is possible to be removed without removing half the motorbike as well. You be the judge.

The cover plate looks quite clean. The previous owner said he did oil change not so long ago, last summer I guess.
It may be possible to slip the cover and cartridge pan out without taking the exhaust off.
