It was also local ( next suburb) - which was very convenient....
It is also eligible for the Period 4 (Post Classic) 250 class - which means I can race it at in the same events as MickLC (and Steve Kairl and also Billy when he is there), but in its own class - which appeals to me greatly
The S1 250 is the smallest of the kawasaki triple family, and was first released in 1972 - (just making it eligible for Period 4.) Here is what a stock S1 looks like............
They run an under-square motor, with 45mm bore and 53.2mm stroke, for a capacity of 249cc. Power output was only 28hp at 8,500rpm. Dry weight was 149.5kg. Light as a feather really !!
Top speed (stock) was just under the ton (154kmh). 22mm carbs ! 
tiny little jiggers they are.......(Interestingly, the much-more powerful S2A - the 350/3 of 1972 with 45hp
- used the same crank (yay) but with a 53mm bore......so a set of S2 barrels can (and indeed will) be fitted to the S1 bottom end.........in the fullness of time.....)This is what I nabbed off ebay yesterday..........
Went around and had a look at the little jigger this afternoon with PC ( we needed a break from fence patrol ). Old mate selling this could start it with just a push from his arm !
( he is in a wheelchair recovering from a big bike prang). The seat/ducktail combo looks much better in the flesh, and I actually felt comfortable sitting on this bike - although that was with stock footpegs which will have to be moved for racing.......
It is pretty rough around the edges though. Needs a massive detail and some work before I can get a roadworthy and concessional rego. But - it runs, idles well, has some great hand-made custom expansion chambers that are all tucked in neatly and sound *phat*. Most of the stock parts are there, although some changes have been made. The bike is fitted with later-model kawasaki mags, with a disc brake front & rear. It is also running larger S2 carbs (24mm). There is a complete Z500 front end that comes with the bike, and a drum-brake rear mag as well. I will have to change the wheels to spoke wheels for P4 eligibility - complete with drum brakes
(in better news - P4 bikes can also run on methanol - so I will arrive at a corner far quicker than the P5 bikes - just with no brakes ! )Spent about twice as much as I usually do on an old dunger - but S1's are pretty thin on the ground these days, especially with hand-made chambers like this - and it's nice to have book-ends in the triple collection.....
See you on the track S c a g
