Very nice! Would just polishing the sleeve and crank do much?

[rjmods.net]

thanks:D .Polishing the crank and sleeve will help.not as much for the sleeve unless work has been done {cutting more ports} .But the cranks intake channel wich you can see some of from the pic makes the diffrence. Stock the channel is very rough from poor machining i guess .but once cut and polished it will be very efficiency fuel will go through smoothly:thumbs:

I just recieved my piston/sleeve/crank via express mail from RJ Mods...I wish the pics did the parts justice, bad lighting and cheap camera make for average looking pics

Here are the before shots

I dont like it.............I FREAKIN LOVE IT!!!! This thing is a true screamer now. I only got about 5 tanks through it today, so its still breaking in after the pinch, but its got big power! Now Im wondering if I really need a new motor.....

[rjmods.net]

glad you love it.:D

rj,

I have a P5 that still runs but needs a sleeve or a pinch. I want to mod it for a technical track no real big straights. What would be best pinch and mod the sleeve or buy new and mod it. I dont want to blow $200 on it or i would buy a whole new motor know what i mean? I guess im asking will there be a big difference between the two options?

[rjmods.net]

it depends on how bad the old sleeve is .if it still has some compression then i could pinch it and mod it and it should be good:thumbs:

[z3usX5]

Well, it has compression with the plug in, not alot but it takes effort to turn it over. It has no pinch without the plug. Its still runs ok, but dont hold a tune well. Does this sound like a fixer upper?

[rjmods.net]

yes its sounds good .if its still tight with the plug in shure its fine.
