TS 100 is it too good for a bucket?

[Rick 52]

I got this this arvo I only looked at it on Sunday and made a gamble $100 Its locked solid but all together I think they might be getting rare. I have never seen one with a twin spark before ,a quick search made it about 1974 its still got the key in it !!

Can anybody tell me more info cheers ...217964217965

Most t/s dirt bikes of that era had two spark plug holes - theory was you could have two plugs installed and when one fouled, you switched the lead to the other plug.

Alternatively you could install a manual decompressor to get more engine braking (worked, too)

Looks like the TC100 I learnt to ride on, does it have the 4 speed gearbox and high low ratio on it? Mine had 2 plugs in the head, if it started running a bit rough because the plug was fouled you just had to whip the lead across to the other one and away she went again.

Probably a rare bike these days, particularly with the exhaust still complete.

...would be a pity to destroy a piece of early 70s classic jappy ... cool thing to have going as a toy...

No such thing as "too good for a bucket" it is after all the Premier class

So you reduce the compression and the motor has more engine braking....
so if I take my plug out- it should make my bike harder to kick over.
Is that what you are saying?:weird:

Manual decompressors were common on old two stroke trials bikes, you can run them downhill engine braking in situations where no decompressor would cause a stall and then when required drop the decompressor and gas and go, instead of being stalled mid section. Was common on BSA bantams, makes a really weird noise in operation.
Masport made an auto decompressor for their two stroke lawn mowers that made it into a number of dirt bikes over the years as a retro fit, usualy higher comp higher capacity two strokes to prevent mid corner stalls. The last bike I remember having one fitted was the Husky 360 that Paul Whibly was using for the Enduro and Cross Country nats a few years back.
Not really applicable to buckets but not as ridiculous as it might seem at first glance.

If you think of a two stroke cylinder, once the ports are closed and the piston is on the way up, the gas above is compressed - that puts a load (braking effect) on the crank BUT once over tdc, the compressed gas acts as a spring and puts a (nearly) equal amount of energy back into the crank.

With the decompressor, it bleeds some of the air out, reducing the "spring" effect. There is also energy absorbed as the piston tries to draw air back into the cylinder through the valve. makea really good farting noise too,

I had a 72 350 Kawasaki Bighorn (single t/s) - with the decomp open it was completely controllable going down steep trails.
Wasn't anything too tech - a holder screwed into the plug hole, had a spring loaded valve (just like a very small 4 stroke engine valve) that seated in the holder, and a cable from a small bar lever to lift the valve of its seat.
Also it's not like the decomp that is used to assist starting large 4 strokes.

I'll give you twice what you paid for it. Neat looking bikes. Find a later TS to race, keep that one std.

[Buckets4Me]

you would probably find he will swap for a resonable engine

Am I right in saying the TC's where all dual ratio?

That cute little thing needs to be restored.

Go bucket a CB, those things are not deserving.

218012TC100 4 speed x2 ratios


why CB when he has a fast FXR

is this bike for your son ?

Yep, that was my beastie, a nice green one.

I think it was destined to be a bucket racer after I'd rendered it too trashed to ever be used on the road again....

Because we all need a bike we can crash :shit:

[Murray]

Yep you are. Had a little lever thingi down near the brake pedal which you just kicked over from low to high ratio or vice versa. Great little bike, I used to go faster up all the fire breaks and trails than the 250's due to the low ratio and lightness of the bike. TC stood for Town/Country. The TS was for Town/Street (I think) and did not have the high/low ratio but was a bit quicker at top speed.

Cheers for the info every body It is a TS no duel box ,I think its to good too be a bucket 35yrs old not bad ,I will get it going and see what happens from there.Cheers for the offer Dave but I think I will keep it for a while.

[F5 Dave]

. . . ok 3 x.

[Str8 Jacket]

. . . ok 3 x.

I'll take it for 5x and then once I have destroyed sell it to Dave for 6x...... ;)

[F5 Dave]

Sold. .

....another irreplaceable treasure bites the dust...:bye:

[F5 Dave]

Nah it's ok I know where Hels lives, I'll just go 'liberate' it before she can muller it:yes:. Might take a while but would be a good stablemate for my Stinger/s. + at free the price can't be beat & she'll just put a post up blaming the local urchants for stealing it & we can all tsk tsk.

I just whipped the head & barrel off tonight and the bottom end is solid i think its the big end ,So a job for another month me thinks ..
