Give it a go and in the meantime I'll look around for a spareAfter not being able to find a new head I decided I give making one a go.
I had to make a new head as the previous owner butchered the original. First he stripped the glow plug thread and then didn't know how to remove the head. This pick is all that was left, I turn it hoping to Tig it up but it's too thin.Give it a go and in the meantime I'll look around for a spare
Well thank you there nitrotrout.First things first, welcome to RCNT, @COPO .
That's one bad motor scooter you have there. Glad to hear you're still running it.
That MSJ cooling head you have is pretty rare these days and worth a good chunk of change if you ever decided to sell it as you probably know.
Original box and instruction manuals are also very collectible these days
I like the piggy back shocks, it gives your truck a mean aggressive look.
Your body mounts appear to be custom made as well as the lower shock mounts. Very nice. How about the wheels, Tamiya maybe?
You're right about the two versions. My project was a V1 with the flat helicopter cooling head and dysfunctional header.
The return nipple was drilled directly over the exhaust stinger on the V1 creating tuning issues.
The pipe was revised on the v2 with a screw plugging the initial nipple hole and the return hole was moved back.
There was also an issue with the clutch assembly on the v1 I'm guessing, My v2 has a clutch setup completely different than the v1.

The MSJ parts are really difficult to find these days. I was fortunate to buy a v2 on ebay that already had the MSJ cooling head and starter backplate
A couple years ago on ebay I found a complete TTR EK4 upgrade kit unopened, it came complete with every red ERGAL aluminum part offered for this truck.
So I got in a bidding war with some guy and I tapped out at $400.00 bucks.
I'm guessing those new parts you posted are no longer available?Welcome to RCNT, @twintec99 I'd love to see some pics of your EK4 if you have some handy. Does your rig have the composite shoes like these

or the steel shoes like illustrated in post #90 ?
So after tearing the motor down because I just had to know if the motor was OK, I do have the revised clutch like yours. Not sure why my motor was stuck...bearing looked all gunked up. I baked it at 300 and got the piston up to 250. It came loose. I cleaned it up and used Mobil one to lube piston and crank. Did they come out with a better bearing that I should have before putting it all back together? I did not want to force the rod off.Welcome to RCNT, @twintec99 I'd love to see some pics of your EK4 if you have some handy. Does your rig have the composite shoes like these

Hi thereSo after tearing the motor down because I just had to know if the motor was OK, I do have the revised clutch like yours. Not sure why my motor was stuck...bearing looked all gunked up.

Did they come out with a better bearing that I should have before putting it all back together? I did not want to force the rod off.
I pulled on it with needle nose and it really was not cooperating. What is your method for getting rod off crankshaft.Maybe I needed to use more force. There did not seem to be any give like smaller engines have. So I hit pause. Motor spins fine now and piston looks brand new. Been sitting for 10 yrs though. So new bearing might be best while torn down. There is really nothing online about this motor.

I thought it looked too high as well. Maybe something happened when the piston locked. I see no damage but with head on, when rotating motor, it feels like it could be just barely touching something. I'll take it to the experts in town that sell RC and ask their opinion. Thanks for input.
