luckly to get an item from my friend,not heard about this ever.that fit for 870C or yz10'94?
with these main gear and rear belt like a whole set

It's a fine pitch kit you can use on 870C and works models.

Any reason it wouldn't work on the 94? Are the diff pulleys on the 94 samller than the works and 870's?

hmm good point - i actually did not try it.

The pulleys on the 1994 YZ10 (also Pavidis) are 33 tooth items whilst the 870C and Works models are 35 tooth. The 94 YZ10 diff outdrives (front and rear) are also specific to this model and are not interchangeable with the Works models.

By the way Crusaderfly, that kit that you have came standard on the Yokomo Works '91 and was an expensive option part. Only the racers that could handle the fragility of the 2mm belts swore by them but most racers I knew switched to the more reliable 3mm pitch belts.

thanks for all above informations, great help!

yeah i tried the rather expensive 2mm pitch change all those years ago and found the front belt liked to slip teeth
still have belts an pulleys somewhere but only used them for one miserable meet. do look nice though and be good for a shelf queen imo

Back in the days people complained about the 2mm pitch but a friend of mine had the works 91 never a single problem with it.
i borrowed it but and i didnt have a problem either and i just ran it never touched the belts just to see if there where any problems but it ran very well and i also came second in an club championship with it.

I have a set of this king pin. but I can't found the information about the part number ZC-204L , anybody can help?

Hi Crusaderlyf,

Those kingpins can be used on the Yokomo Works '93 bellcrank system. They hold the trackbar onto the steering bellcrank. For the Works '93 they were option parts and as far as I know, are not used on any other Yokomo offroad car but maybe the touring car range.

Hope this helps.

Are they the same type of screws that i've seen used sometimes to mount the front shock tower?

Good eye DerbyDan. I have tried to use the same length versions as Crusaderlyf has but they are too long for the front shock tower. You could cut them down or use the shorter (aluminium slotted) kingpin screws.

They look a bit like the kingpins that were used with the alumium c-carriers of Kose. those had a small bearing on top and in the bottom.
