I m sure is long lsn. Only SOS will use short. A way to check it is by removing filter boot n wot, observe the lsn edle movement from jet area.

1. With 30%-50% throttle input, lsn pull out completely = short
2. With 90%-100% throttle input, lsn still/out = long

Short or long is easy to check, u never know? Wonder how u tune ur engine

LOL haven't actually checked that.... just getting some input first.

I've noticed after a couple of good runs, the front bearing has kind of like a gooey, dark dirt build up covering the bearing. Is this a fuel leak due to very rich break in? Is the bearing still runnable?

Neal, can you elaborate on this engine more and make comparisons to previous higher port Novas? crank specs? Thanks

I've been running an OS Speed spec II in my Truggy. Was thinking of trying a Virtus 7 port.

Anyone have first hand experience with the 2 engines?

Anyone try new manifold 41033/2096 combo for 7port engine? Any feedback

2 of use tried this weekend. We both went back to the 41021 on our 7 ports...

Also try the 41001!!

Mind to elaborate detaily, just curious

So wanted to ask anyone know who has any P/S/R in stock for the P5? My P5XLT has lost its pinch, and would love to go with a new P/S/R but at the same time feel like I should just get a new P5XLT :/

Having been directed here...

amain has the p5 for $185. so probably just worth getting a new one. thats what i'm going to do.

Have you ever had it Re-pinched before?

I believe they (Amain) still have a Hot Mod P5 in stock too!! which is like the sickest engine deal you can get.

Yes it has been. Which is why I thought next step would be a new PSR. But I will look at just a new motor, may be easier and less hassle.

Thanks for the help and links.

I would measure the crank pin before buying a new p/s/c, usually it wore out after hard running. If d crank pin NG, just it pinch n run it again. New engine is best solution
