The new addition - Period 4 - S1 250 triple !!

[Gosling1]

I would never stoop so low ! if this little bike works as a 250, it would be interesting to see how it would go as a dinkum entry in the bigger class in a following season ? May not happen for a while, as the 350 stuff is pretty hard to find........

Ah , the old Yellow plate 350 trick huh ???

I always thought the trick was to put a green plate on a 350

those old stinkwheels live & breathe !!






Lots of things happened with this bike recently - a Marulan track day in August ( where the above picture was taken by Ray Oxford) - a couple of VJMC ACT rides - the recent Toy Run......it has had a few good outings the little triple, and been very reliable on every trip....

oh thats right - it also just about broke Brett's dyno on the dyno day back in August :laugh: - 40-year old unshielded electrics will do that every time.....

here is the dyno chart from back then - 26hp at the back wheel was actually a good result, they only put out 28 at the crank when new. The slightly bigger carbs (24mm S2 v 22mm stock) and expansion chambers are the reason for the hp increase.

haww good stuff

Do they do a write up and a bio, you know likes, dislikes, fav position etc

[Gosling1]

no write-ups mate - but normally the *big* photo takes home some kind of prize ?? bag of goodies from a bike shop or some such ......

nothing this time around though

Maybe they thought that me getting off the bike in one piece was enough of a prize

Nice

I've ridden it, it's awesome....and I didn't even call it any names! (sorry Billiam)

.....I've ridden it, it's awesome....and I didn't even call it any names! (sorry Billiam) ......

it was those skinny tyres Bill !! he couldn't wait to jump on the baby triple and give it some lovin'

Have to say - a few of us were waiting at the T-intersection up at the top of Mt Mac waiting for Mick to get back from his short strop - and we heard this little jigger maybe 20 seconds before he came into view ?? it sounds *fantastic* at full noise, a reall banshee scream and Mick was fair up it for the rent as well.....

It had no oil-pump when I first got it, so has always run on pre-mix. It seems to really like a 30:1 mix of R30 castor oil......after 5 minutes of riding, there is almost no smoke at all coming out the back......well not that I can see

Can't wait to see how this baby goes on methanol at the BSFOS !!

Awsesome vid,they sound great!like a 20B rotary.

[Gosling1]

well I was googling for some H1 port maps for Dave , and found these pictures of a modded S1 from Canada ....

how cool is this little jigger ??

[ProblemChild]

nice.

Been a while since an update on this little jigger......and time is of the essence now

Last year I sorted out some new wheels for the S1. Darryl Groat from Moose Racing laced me up some nice ally rims - although it took some convincing to get them as fat as I wanted Anyway they now have some nice Avon AM22/23 tyres fitted, the rear is a special construction especially for skinny rims, 130 section can't go fast on skinny tyres someone told me, sounds like good advice....

Been busy over the last couple of weekends sorting out some mods to make sure these new rims fit, the old wheels were 70's-era OEM kawasaki mags from some unknown model, with a disc brake front and rear. So I had to modify the fork leg to suit the twin-leading shoe drum brake front end......and fit up a new swingarm to the back. The swingarm that was fitted, was too narrow for the new fat tyre The replacement swingarm is from fuck-knows what, but it is steel and the right width came with some spares when I picked up that GPz600R a couple of weeks agol.

So new shock mounts have been welded into place - and the back wheel now looks pretty good fitted up. Same with the front-end.....the spoke wheel and drum brake look much more period-specific....

One other interesting thing about these drum brakes.....I had to source them from ebay as I have only limited parts for these baby triples. The brake drums came with old fucked shoes as you can imagine. Today I was searching for replacement brake shoes for both ends, and found a few examples across the US for about $70 per pair delivered........hmmmmm. Maybe I should check that stash of NOS drum brake shoes in the 4th ?

Many years ago I picked up a stack of parts in Sydney really cheap - it was a bloke who used to own a shop, and had shut down some time earlier. His missus was sick of all the parts taking up room in the shed, so he cleared out the lot for SFA. All I was after was all the disc brake pads for Z1000 models - I think there were about 30 pairs of these in the original Vesrah packaging ? So I got those, together with a heap of other brake parts ( and other stuff ). .....today I went through that pile of brake shoes and found 5 sets of rear brake shoes for the S1/S2/S3 series ( also suit a lot of other smaller kwakka's from that era). These were still in the original Vesrah packaging. Win !!

But couldn't see any shoes for the front twin-leader. I did have some front shoes but they were marked for Suzuki T315 and T250 models.....well I grabbed a pair and sat them next to the shitty front shoes.......fark me they were identical ! There are about 6 pairs of these in the stash !!

So pretty happy with that outcome, I won't have to buy new brake shoes for at least 1 season

Will bung some pics up tomorrow, the bodywork was painted up in winning lime a few weeks ago and looks heaps better than the baby-blue paintjob that came with the bike. At this stage the frame and motor still have not been detailed but that will happen over the course of the season. All I need at the moment is some good log-book photos. First round is May 4th !!! FMD OMFG !!!!

Git-r-dun!!!!!

I've been working feverishly..... ok, casually, on the LC to get her ready for the NSW Titles for a shakedown run so that it's ready for the first round. You better be there with the baby triple ready to rock n roll! I can't wait for it, it should be a ripper round. I take it you, Stace and Mick will be garaging together? We were hoping that Robracer, Leanne and myself could get a double garage with you guys and there would be two more spots for anyone else that you had in mind to join us. Stevo is going to pit with his usual crew. It would be cool if we could request a triple garage so that we could all jump in together and avoid any unnecessary walking.
