Cylender Dilemma!


Recommended Posts

OK Heres the deal.... I have .100 over jugs in good shape. I took them off for a cleaning and to replace the pistons/rings just because its been 2 seasons. Compression is still at 150 in each, with 19cc domes. So, a buddy and i did some clean uo grinding in the intake/exhaust ports before I got them PCed and Honed. After I got the jugs PCed, I noticed my buddy slipped with the dremel, hitting the inner cylender wall!!!!!!! So now im screwed and probly have to resleeve(cause im maxed out for bore), having to return my .100 over piston kit and start from scratch. Ill have pics up later of the gauge in the wall. I also wanted to do some porting while i have them off. On another note, I can get all the sleeviing machine work done for free from a really good machinist.

 

Sorry for the ramble-on, but what the hell route should I take?????

Damn, too bad my budget is as tight as a virgin or Id be all over the cub deal. Yea I found sleeves for cheap but I also had my domes cut for the .100 over bore!!!! Youll have to see the pics to really evaluate how bad it is, but keep the cylender deals comin, im down to trade if anyone wants a .100 over cyls + a lil cash. Like I said, this had a solid 150lbs in each cylender.

These guys are probably thinking he sat there can gouged out a hole in the liner. If it was just a little slip and it was low enough on the cylinder (under the port roofs) I would not worry about it. Take some 600 grit and lightly go over the marks to be sure there are no burrs sticking up and run it. If you look at some cylinders that have been ported you will occasionally find some cylinders where the guy got lazy and drug the port chamfering bit across the liner to the next port. I've seen it a ton of times.

resleveing cylindars are very very costly.. go call someone and ask them how much thed charge to resleeve cylindars.. shooo billlll.. by the time u buy the sleeves, get them changed,honed and pistons, u coulda bought a virgin set off ebay at 300$ twice,, and i also agree id just go with the cubs if your goin through all that... TRIPLE PORT!!!!!
