Seem to have everything else but piston sleeve for the 5 port...

nothing on ebay

That is odd that they are not carrying parts for the different engines they carry.. I realize that if they don't carry it then Stormer can't get it...

Need a little help.

I've had an alpha .24 and now have a 2013 pipe. I've been running it on the oval and we run about 3 min races. I was pretty sure I had it tuned just right. I've been thru about 3 gal including break in.

The problem came when i converted it back to buggy and ran my first off road last night with it. I made it thru 5 min heats no problem just a tad rich thru the night.
All of the sudden about 8 minutes into the main it started stalling and just terribly rich. Pit guy leaned it a little and it got better for a lap but then back rich again. Leaned a little more and got better and finished the race but so down on power.

Is this a common thing? I've never heard of anything Like that. I didn't get a chance to temp it after coming in so I don't know what its temping now. It was in the the 267 range before.

clogged air filter ?

Can anybody confirm that 3port piston sleeve fits 5 port jared tebo edition?

I talked to guy at the local hobby shop I bought the motor from and claims it is most likely just now breaking all the way in. He said on oval 3 gals probably hasn't been enough to do it but offroad was. This sound legit? Air filter is still clean.

The symptoms you describe sound just like an engine dropping it's nuts.. I'd retune it and run it..

Edit: According to Pitpop it will not work, the flange diameter is different from 3port to 5port.. He would know better then me..

Oh man thats great news. I guess now maybe it'll have the top end I always thought it was missing. Oval boys betta watch out lol.

It won't fit. The diameter of the upper flange part of the sleeve is bigger than the 5 port sleeve. If you want to put a 3 port sleeve into your engine, it needs to be a 3 port from the start. I have no idea why they did that, don't kill the messenger..

On another note, the 7 port p/s is a BEAST Cody has been running one in his truggy. and I'm going to build another one because it was so good.

Hey Paul thanks for the update and fixing my mistake.. I really hope he didn't order a 3-port P/S on my word..

did not

and dont need it now but may need it later.

thanks

That's good to know. I usually defer to PitPop when I'm not 100% on something, but I didn't figure they would change something like that.. That's what I get for assuming..

my crf JTP worlds edition engine needs a new rear bearing .. i cnt find it in amain .. can anyone tell me if the werks or sirio or any lm bearing will fit this engine ? werks and orion are similar in size 14.2 x 25.3mm but i dont knw the width ..

They should be 6.3mm. I ordered two TKO ceramics in 25.3x14.2x6.3 for my Discovery engines. I hope to install them Firday afternoon. I'll let ya know if they work.. Bearing sizes should be the same for all the Alpha line of Orion engines.
