Australian Karting Forum

This is the other kart my mate picked up also supposed to be a zip

I cant find a chassis number on this one.

again any help identifying make model age would be appreciated.

and to push my luck, if anyone can ID these karts would like to know what they looked like coming out of the factory in their day as the karts came with buckets of spares and there are plastic rims, 3 piece rims with tubes, Dino stamped rims.

thks in advance

Bob

Bob, I'm taking a guess at 77 - 79 Shadow. The 76 Shadow had a nylon swivel bush at the lower end of steering column. Also 76 only had right hand bolted rear nudge bar and a welded left. Yours has both bolted bars both sides ? 

To me it looks like you have a 79 Zip Shadow GT ?? Mine was a 76 Shadow. (note the lower steering bush)

Tom,

thanks for the tip and picture,

it looks like yours has split rims and tubes, so is that what they came out with?

Regards

Bob

Bob, they did use split rims but tubeless. The halves are sealed with RV sealant (not silastic) . I found the ZIP brakes hopeless and fitted MCP units from Comet in the US. Most of the zips here came from DPE who were the local agent and the wheels don't always have the ZIP trademark. The Zip fibreglass tanks are also now far past their use by date.

Tom.

I agree with Tom. It is probably a Zip Shadow. A good Kart in its day. It certainly would have had split rims when new. Some tyres still used tubes at the time but tubeless were becoming common. I seal mine with silicone but use a light skim of grease on one side so I can get them apart again.
The mechanical brake looks like a Swiss Hutless - one of the better models of brake.

Mike, another drama with the split rims is the valve stems. Original Zip rims had 45 degree metal stems. If you use the modern stubbies the hubs are in the way of tyre checking. I was eventually able to get short 90 deg stems from US. The RV sealant does not harden like silicone and comes apart pretty easy.

thanks gents for the tips,

 Bob I have the same Zip as yours it is a 78SE the rear brake is no correct it should  also have a tapped axle I bought my from Drew price in 1978, 78 SE also  have one seat stay only under your knees the other one is on the chassis rail and the split rims use o rings to seal and rubber value stems not metal  I still have many sets, both nerf  bars are bolted on also.My  chassis had no  stamping of any kind as well

The rubber valve stems are useless on the front hubs, you can't get an air chuck or tyre gauge on unless the wheel is removed. I've attached a photo of the problem and the original 45 degree stems. New centre 'O' rings can be found at bearing suppliers. I spent a lot of time finding the secret of how to fit them LOL.

Tom.

Chris,

yes the brake was fitted for dirt use, the purchase came with a heap of spares and there is multiple master cylinders and hydraulic calipers, its just a matter of working out which is the original.

If you have the original brake setup would there be any chance of you posting a picture of the master cylinder and caliper so we can id the correct one?

Thanks

Bob

 Bob, I can post a picture of the hydraulic caliper, I read that Zip also use KP brakes when demand was high but production was low, a lot of  pictures of zip karts on the web show that they have KP brakes fitted , Bob after looking again at your pictures I noticed you zip had 2 bearing which means it is not a Zip 78 SE may be 981 or 935 sorry about the bum steer mate

Chris,

that would be great if you could post a picture as he has 3 old brake calipers in the bundle and it would be nice to know which caliper is the correct one?

even though its probably a crap caliper it would be nice to keep  the original with it.

Regards

Bob

These are the original Zip caliper and master cylinder. If you have them use at your own peril !
