This is a classic one from using 4 stroke starters in 2 stroke skis

4 stroke starter motor

One of the best legal SJ Ski Spec wetpipes ever made for racing. Basically a legal wetpipe that is close to dry pipe performance 800 including the trip Yes its a bit dirty. Im cleaning out the garage of parts and this was taken off a ski and put on the shelf a few years back and its just sat...

You need to know the port timing before you can simply put in a stroker crank. It changes the timing a huge amount.

I have a couple of west coast cinders with the aux port in them and a pjs but I dont have the casting in the pjs one for the ports. Its a reed case cylinder but it must be an early one

Damn I wish i had seen that

Looks like a stock crank to me. its definitely a 90.5 mm piston in there for a cr500 wossner made it. THey have been filling on the bake of the transfers a lot for some reason on the out side.

You will also need a new cylinder as the port timing will be all to heck with that extra 10mm of stroke

Yeah it looks liek a lamey for sure. I have never seen one witht he extra exhaust ports in or the extra transfers. Its two more than a normal lamey ever had. Very cool

That's a very cool old school cylinder would love to own it or know more about it

Yes reach down and rotate the cloudier with you hand. Disconnect the battery before please

If its a 6mm and the clearance has all been found by jacking the cylinder. You are going to have some damn high port timing right there

I love that shot of all the stamping dyes up there

If i could get this to Australia it would already be in the shed

Could be a broken reed, Reed stuffers will do this but they will normally do it from both carbs

No it will not misfire the rear cylinder just make it slightly retarded

Interested, can you post pics from the inside

We have been working on that drawing. It’s actually a lot further along than it you would think

I thought I would repost this so i dont have to re write it when people ask why the exit doesnt taper out on our manifolds. Getting ready for the stuffer conversation They are not reducing crankcase space as more reed area space. Think of it this way, you have a very fast moving column of air...
