Touring on a KR-1R...?

I found a feature in a Japanese magazine from 2017 about a tour of Hokkaido the previous year. This photo caught my eye: https://i.imgur.com/9WaPhPX.jpg The owner, Yoshiro Fukuya of Sakai City, Osaka, had apparently toured Hokkaido 22 times previously and was along for the ride again in 2016 for his...

Re: KR250B3...?

At what point do the frame numbers of the B3 and C4 start- is there any official record of those numbers? And would they have had new colour schemes? I'm not sure of those details Gerrit. The specifications book doesn't mention frame numbers for any of the models featured and I've never seen any of...

Re: KR250B3...?

. . I have a later book that lists the 1992 C4. the fourth year of the C 1989 model... B1 is a 1988 KR http://kr-1s.co.uk/forum/viewtopic.php?f=7&t=1354 I think even if a model receives no updates the model code rolls on with a numerical revision that determines the year. When updates are done sign...

KR250B3...?

Ever heard of a KR250B3? I hadn't until I found this Kawasaki book: https://i.imgur.com/obbUSwK.jpg The book (Publication No.99926-1016-01) gives specifications for Kawasaki models released for the 1989 and 1990 model years. As well as mentioning the KR250B2, KR250C1 & C2 and KR250D1 & D2, I was sur...

"The Kawasaki" magazine

Sometime ago I came across Volume 2 of this magazine and it caught my eye because of the nice blurry photo of a KR-1 at speed on the cover: https://i.imgur.com/c0fOgkh.jpg I waited for a 'cost effective' copy to come up for sale and bought it, but was a little disappointed to discover there was very...

Nice work Bernie. It looks as if the Beet replica vents should present no problems 8) .

Re: Cycle Sounds Magazine, January 1988

I'm glad the material is of interest, although the translation came about more through persistence than language skills...! great stuff James I wish the magazines back before 1988 had more colour. Apart from Beet, I wonder why no one has done replacement fairing vent panels to look more like the F3 ...

Cycle Sounds Magazine, January 1988

I found this magazine which had a feature on the launch of the KR-1 and the associated Formula 3 kitted machine (KR003). I have scanned the original article and added translation pages at the end. I translated the article and photo captions as best I could using Google Translate (and my kanji & kana...

Re: boggy running between 3-5k at 1/4 throttle

Is the poor running more related to engine speed, or to throttle position? Are the needles new because the original ones were worn? If so, could the needle jets be worn also? My own KR-1 (basically standard except for KR-1S pipes) runs better with the needle clips in position 2 (i.e. second from top...

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. I'm convinced it is the same thing with ...

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

The KR250 was originally sold new in Australia too, so you can usually find a selection of parts on Ebay Australia. I don't check regularly, but at times have seen a fairly large selection of bodywork, engine and chassis parts.

Re: KMX oversized piston.

The 200 fits the 125 cases and the crank is the same 54.5mm part too. Its just stuff like the carb, radiator and clutch that are different, and I've got upgrades for all those ready too. The only problem is if I fit the 200 top end on this engine, the custom pipe I've got won't really work, and I'v...

Re: KMX oversized piston.

a sleved one is always inferior, not matter how good the job has been done. because of the lesser heat dissipation between sleeve and cylinder. don't think it will matter much in one "underpowered" KMX though. Yes Jan - I agree. As you point out, the cooling "inferiority" of a sleeve may not be not...

Re: Squish clearance and compression ratio - advice please!

Please could someone tell me what the standard piston dome radius is... I'm not sure if you still need this info, but the dome radius of a standard piston is about 120mm. I found it difficult to measure with accuracy, as I could only use a profile gauge to get a trace of the dome profile, then comp...
