Hmm...the osspeed crankshaft looks like this... Hope this helps

Nope, doesn't help at all.

I'm looking for a packaged part with the header still attached. One with the right part number. Something to show to the US distributor. They claim they are "invalid numbers".

I was wondering if the one that uniquexme got looks the same as the one in the picture.

ah, i have forgotten to take the photo again, i guess u guys made a mistake, i only have a new pack of piston/linear, not the crankshaft. yes, thats OS Speed crankshaft.

It doesn't matter. Any of these parts.

These are the part numbers.
Crankcase – 21531100
Crankshaft – 21532100
Piston & Liner – 21533100
Heat Sink – 21534020
Carburetor Assembly – 21538020
Carburetor parts (Needle Assembly – 21538510), (Reducer 5.5mm red – 71533155)

tried to upload the photo, but as u know in asia, the broadband is like shit lately due to the earthquake. so m unable to upload. sorry.

here's the photo.

too bad, great planes, the dist for os usa, does not care about
support for this great engine, otherwise I would have sticked to one of the two I purchased in japan when this engine came out

happy racing

Is this a picture of a 5 port converted to a 3 port and availale from OS?

I with draw my question... I understand this is the sleve for the Speed motor which is just what I'm looking for. To not have to covert a 5 port into a 3 port.

can some one give me the hsn and lsn settings for the os vzb v spec please

LSN - Rotate the Metering Needle until its slotted head is flush with the ball link body. This is the standard position.

HSN - Open the Needle-Valve 3 turns from the fully closed position.

Most excellent news!

Good news to all O.S. Speed owners currently looking for a new piston/sleeve set. Is is now available at a kick@$$ price..

Enjoy..

Hi everyone is it possible to change my os tz 3port to 5 port piston and sleeve or just the sleeve? I will race on outlaw. Pls. LMK guys and thanks.

Yes, but why... This new 3 port sleeve is a 5 port sleeve with the connector (rib) removed making it 3 port legal... I would recommend that you change out the sleeve, piston and rod. Then break it in.. and depending on how much time you have on the engine, the bearings may need to be replaced.
