I think the SMR is Fucked!

so I got my new plug cap in, and still no start. I double checked all the electrical connections, stator, coil, etc, and everything is right on with the resistance specs in the manual.
I had checked the compression before, but the auto-decompression throws it off. so I backed out the exhaust valve adjusters and re-checked compression and only got around 125 psi. it's a 12:1 motor, so my math skills tell me that number shoudl be around 170. even worse, I could hear pressure leaking down into the crankcase.

I sprayed a little oil in the compression chamber and re-checked. sure enough, the pressure went up a little (140 max), but I could still hear a distinct hissing sound coming from the middle of the cylinder.

should I even bother with a leak down test, or just start digging a hole and call the concrete company? Tony, you're coming over to help dig right?

Bill check to make sure the head bolts and cylinder are torqued down. If that doesn't do anything take the head and cylinder off and lets check the piston, rings and cylinder wall. I bet you got a little scoring on the cylinder from when it overheated. If you need any help let me know I'm sure you can handle it.

Bill I was just thinking try scaring the bike into starting like you did with my YZ. It works.

dude, I tried. the KTM scoffed at my scare tactics. I even measured the forks and shock to see if they would fit on the DRZ, and it still didn't budge.

What mind of condition are the valves in? Those valves can get cupped along the seats, which would make them not seal properly. If the previous owner wasn't on top of his valve checks, that's a possibility.

if the cylinder is scored, could you try running a hone thru it and dropping in new rings?

so I finally got around to tearing into the top end. scratches in the cylinder wall.


at this point I just don't have the time/money to keep this bike and fix it. I broke it down into parts this weekend. it was a sad site. best bike I've ever ridden.

I'm sure I could have it honed, replated, or even find a replacement jug on ebay for a few hundred bucks. but right now I need the money more than I need a racebike. I'll make some decent coin on the parts, and keep a few choice components for the DRZ (brakes!)

Sure, that makes sense. Cash is alwasy good. Just so you know, my yz125 cylider had a crack in it and they welded it up replated it and painted it a fresh silver for $225. came back looking like new. It was the place up in WI that I cant remember the name of.
