Re: Various KR bits and pieces for sale

Re: Cycle Sounds Magazine, January 1988

Thank you for your hard work, James! I wish I had your language skills, would be very useful in understanding the Japanese "Racers" magazines I have. Still, one can learn a lot by examining the photos of the bikes very carefully.

Re: Hybrid project

I haven't definitely decided yet which setup I will be using for the rear caliper assembly, but it will be either the GB Moto setup for the vj22 RGV: https://i.postimg.cc/7hz74VdJ/103_GB_Moto_caliper_assy.jpg ..... or the Tyga rear caliper bracket for vj22 RGV: https://i.postimg.cc/T1kPZWY5/104_Tyga...

Re: Fitting the YZF450 Radiator

Thanks for the drawings, Bernie! Will be very useful if I decide to use this rad for my project, though currently I'm considering an aftermarket KFX450 rad. By the way, unless I missed something you didn't specify the material thickness for the brackets- 4 mm????

Re: Hoping to buy a KR250 - what do I need to know?

If the part numbers of the vital parts (cylinders, heads, ignition, exhausts etc are identical for the Japanese and export versions then perhaps all KRs really had 48 hp and 45 was a figure released for the Japanese market to "comply" with local regulations. The only 45 hp KRs may have been those su...

Re: Hybrid project

With the LH spacer's width reduced to the required 10 mm I can now confirm the width of the RH spacer to be 6.3 mm and can get it made. From left to right: LH spacer, sprocket carrier bearing and spacer, LH wheel bearing, wheel bearing spacer, RH wheel bearing, spacer, vj22 RGV caliper carrier, and ...

Re: Head gasket failure causes

I have a 4DP TZ250 cylinder which has "O" rings around the combustion chamber and the perimiter; the head bolts (6 per cylinder) are sealed by gaskets according to the 4DP parts catalogue, part No. 90430-06616. I don't know whether these are Dowty seals or simple copper rings, though.

Re: Head gasket failure causes

The "O" ringed head I have has grooves for rings around the combustion chambers only, dimensions of the grooves are: ID 60 mm, OD 65 mm, depth 1.7 mm so the "O" ring cross section is probably 2 mm. The head has also been skimmed significantly, about 2 mm, and new combustion chambers cut. The spark p...

Re: Head gasket failure causes

All of the cylinders I have (both KR-1 and KR-1S) are 90.6 mm and I believe that is the standard height. As for the head gasket, no doubt there are aftermarket gaskets available. One of the heads I have has grooves around the combustion chambers for an "O" ring which is a superior arrangement and I'...

Re: Couch potatoes and Gamers

I had a motorcycle sim (MotoGP2001?) which I tried a couple of times riding Jurgen v.d. Goorbergh's KR3, but I didn't persevere with it. Should still have the CD somewhere though. The only sims I currently have installed on my desktop are two flight sims (IL2 Sturmovik 1946 and Il2 Cliffs of Dover) ...

Re: Hoping to buy a KR250 - what do I need to know?

Apart from being sold in Japan, the tandem twins were oficially imported in Australia, New Zealand and South Africa. Those countries are the best bets for parts (and perhaps complete bikes). Only a few made it to Europe as grey imports outside official Kawasaki channels.

Re: Recommended grey importers for a KR250

Thanks to changes in US laws vehicles over 25 years old can now be legally imported and registered for street use without too much hassle. This means that Kawasaki KRs of every variety, Suzuki RG(V)s, Yamaha TZRs etc which for so many years were Forbidden Fruit to Americans are now also being snappe...
