    Getting my sleeves resized.....

    I think I'm going to send 2 sets (2.5,3.3) to ray racing to get resized does it matter if I send a piston that was in one motor with a sleeve that was in another ?

    Also should I take my connecting rods off before I mail the P/S or just leave them on?

    No as long as the p/s are 3.3 and the p/s are 2.5; and on.

    Remove the conrod, and ask him to give it a medium pinch. If you don't it's so darn tight I've seen pull start break trying to break them in...

    Just make sure you conrod is in shape, otherwise it will all be in vein.

    Make sure the ends are not ovalized, cracked, and check for play.

    You check for play by placing 1 drop of light oil, household 3 in 1 oil works well, you put the drop on the point where the conrod meets the crankshaft, turn the flywheel back and forth, if the 1 drop of oil pushes out completely, the conrod needs to be replaced....

    Ray racing does a good job, I see people getting about 3-4 gallons from his work and that's with 3.3's... Other engines I've seen go farther... I know about 1/2 the guys at the track I race at use his services... Not heard 1 complaint.

    I've used him and no complaints here. He had it repinched and back to me within the week along with a note about what he found with the piston and sleeve and what do to to break it in. Worth the $23 I spent.

    Make the sleeve just a little bit smaller to regain compression.
