Can this sleeve be honed or needs to be replaced? It's a 87 head with a small chip and crack near one of the ports other than that the sleeve it is really smooth. The crack protrudes out about 3 thousands of an inch and the chip does not protrude out. Just trying to save some money. Local shop wants $300+ to do a resleeve job. I have 2 pics posted at bottom. Thanks.
Whenever I came across the bridge being broke I've resleaved. Was afraid of it making a hot spot or catching a ring. No sense in repairing with new parts and worrying of a fail or just to do it again. Not sure if there's a fix for it
So you're saying to replace sleeve?
Unless you want to catch a ring.
So you don't think honing will smooth out the chip?
Cut the bridge out all the 86 rms dont have bridges there basicly the same cylinder as the lt if its ben ported real big u would want to resleeve it then
u can probly chanfer the chip in the port to keep it from catching the ring most builders will recomend a resleeve
DO NOT CUT THE BRIDGE OUT. That port will break the rings and swallow a piston on a 250 engine. It is way too big. A RM port is oval and narrower. The bridge is there to support the rings So they won't push and catch on the ex port. And the roof is flat adding to the problem.
No, honing will not fix it. It will ruin the rings.
Sleeves are readily available for the 87 250,s.My 87 sleeve
**** on the bridge so had to get it resleeved.
I found that its cheaper to buy a GOOD new top end
Most heads I have found are around $500
Not brand new just a good used one. You can find complete running motors for 800
I have a complete cylinder piston and head here ready to go. Its nick Kimmels was for his build he sent it to me and the bottom end was toast. I need to send it back to him unless he sells it then send it wherever. Having heard from him in she come to think of it.
I am willing to buy a good running engine or buy a good top end head. I have about a $1200 budget on the engine.
I have a complete small reed motor previous owner said bike is a 90' haven't had time to check. I will sell the whole motor cheap needs to be gone through clutch cover was off basket appears to haves broken finger and kick start gear is messed up pm me if you want more info
