Default my V-spec is getting tired is it worth getting it Pinched?

as the title says, and how much would it cost, and where can i get it done at the cheapest?

I don 't know if they still sell them or if you can find them any longer, but I used to have the Sizemaster sleeve pincher. It worked great and I used to pinch sleeves for the LHS. I bought it for $49 I piinched many sleeves and would get at least another couple gallons from the motor. So I think it is worth it. If you send it off to someone thanI think you could expect a few more gallons. I wish I didn't sell my sleeve pincher.

you can send it away and have it repinched for as low as 15 bucks. try O.S. rocket. there's plenty of places that can do it.

even if you decide to buy a new engine, a pinched old engine makes a good backup.

don't buy the tools to do it yourself, they give you a wonky sleee, so you get pinch but even less compression than before. Find someone to send it to (with feedback) and let them do it for you. The piston sleeve should come back almost like new!

I too agree with getting the motor pinch. It will not last as long as a new piston and sleeve, but well worth the money if your motor is not going out in other places.

How are all the seals ? Leaking air ?
Bearings ?
Is the creank showing wear ?
And how about everything else ?

But I believe you are starting in the wrong direction. Joe is right. Price is not what your looking for. Find someone with alot of positive feedback. There are many good places out there. I have used rayaracing and was very pleased. Do a bit of research first. Why try to save 5 or 10 bucks to bring a $300 motor back to life ?

I'll be having my RB S7 pinched, then keep it as a spare/foul weather engine. The bearings are ok, as is the conrod and crank. Just doesn't make sense throwing away an engine just because its lost its pinch.

I've used rayaracing.com many times with greaaaat results. Good prices too.

I recently used a guy off these forums and he did a very good job as well. Even better price. Here's a link to his thread

I have not used RW as of yet he is a great guy, and he knows his stuff, I have had great luck with os rocket, better than new when I get them back, this would be the ideal time to replace the bearing with some TKO ceramics and the rod, and have some fun with this motor

Send a message via Yahoo to infanterene

Maxy from Maxys fuel does a great job too.

Number one thing on any motor is to make sure the crank pin is not worn, especially the V-spec. It has to be measure with a mic not a caliper and checked all the way around, they only wear on one side.
