How bad is it?

[RivMan]

So I recently purchased a 61X/61X SN from a member down in GA. I got it home and just now started to mess with it. It has perfect 175/175 Compression with ADA 35cc domes, and a Jetmanic port job.

I noticed that when I fired it up, there was a little smoke / fluid leaking from under the coupler side base gasket, onto the intake. I pulled the cylinder, and the gasket was blown out there, and there's a noticeable ridge / evidence of a lean condition on the cylinder wall / piston.

It still has good compression, and I'll be fixing the lean condition. Should I toss a new top end on it as well, or keep running it as is until the compression starts to suffer?

Thanks

need pics, to determine how bad it is. But with good compression, I'd lean towards running it.

You can see here where the gasket sealed, and where it didn't.

I'd run it till it blows then replace

I hate when a perfect summer day comes up and then you cant ride your ski because of a motor problem.

Replace it now - then you wont have to worry about it later

that is absolutely nothing. put it back together and forget about it. maybe use a higher quality base gasket and make sure its torqued properly. i torque those base bolts/nuts to 35 with a snap-on torque wrench.

Polish the piston with some scotch brite pads may be hone the cylinder if you want. If the rings look good run it.

Agree with blue, hone it, run it

Don't forget to pressure test....
