stokes77 Posted July 1, 2009 Report Posted July 1, 2009 (edited) So last weekend went up to the mountains in crowsnest pass(about 3000ft higher then I currently am). Right before we left I installed the TORS removal kit, cleaned the carbs, and dropped the needle one position(it was at 4th from the blunt end so I put it in the middle). I didn't change the main jet, because it was all ready running a 230 main jet which I felt was kinda low with pipes and an air filter in box with lid on. However the the spark plugs looked pretty good, nice chocolate brown. Made sure the carbs were synced up. Took it for a rip up and down the alley and bike was running pretty good and idled great. The motor in this bike also hasn't ever been rebuilt, it's a 2000 so that's 9 years no top end work done. Bike didn't want to start when we first got to the mountains. Finally got it going... wouldn't idle. I figured elevation had something to do with it. Put new spark plugs in, adjusted the idle screws and didn't get a whole lot of success. Rode it for the morning and it was running allright, bogged in the lower end, was screaming at the top, but just couldn't keep it idling. I checked the plugs after our first ride and the right side was saying lean, so I pulled the carbs apart to make sure everything was good to go, ended up moving the needle clip back to the 4th from the top. Later on that day was riding it around some more, and hit a fairly big puddle, the bike died, I tried to kick it over and the kicker was seized. My buddy figured we should just push start it, so we did that and it actually fired back up, but it had a huuuge loss in power after that. I figure this is when the right side went. I took the bike for a short ride the next day and it was backfiring like a son of a b in the low end but once I got it revving it actually rode all right... I am sure it was running on just one cylinder though. So what do you guys think happened? Was it just the motor's time to go? Or could hitting the puddle have done this? I took the jug to a local guy today and he figures I need a whole new right cylinder. Sorry for the long post but I just wanted to make sure I included everything. Here are some pics of the carnage: Edited July 1, 2009 by stokes77 Quote
SAVAGE420 Posted July 1, 2009 Report Posted July 1, 2009 (edited) Sweet. :thumbsup: Look at how white your plug is in that pic!!! Detonation at its finest right there!!! Edited July 1, 2009 by savage420 Quote
black sunshine Posted July 1, 2009 Report Posted July 1, 2009 Definitely do some jetting research while your waiting for your parts to come in! Make sure you don't have any air leaks when you put her back together. Quote
stokes77 Posted July 1, 2009 Author Report Posted July 1, 2009 Sweet. :thumbsup: Look at how white your plug is in that pic!!! Detonation at its finest right there!!! That's a brand new plug that I put in trying to get it started, after the cylinder seized up. Quote
stokes77 Posted July 1, 2009 Author Report Posted July 1, 2009 Definitely do some jetting research while your waiting for your parts to come in! Make sure you don't have any air leaks when you put her back together. Ya I am planning on running 260 or so mains if I get a stock port motor and working from there. And I will do a leakdown test once I get it all back together. I really should have done it before I took it apart, but it was Sunday night when I got back and I just couldn't wait to take it apart.

stokes77 Posted July 1, 2009 Author Report Posted July 1, 2009 I forgot to mention, I don't know if you can see it in the pictures, but the top pin that holds the ring in place was missing on both the right and left cylinders, could that have caused the ring to move over on the right one and catch one of the transfer's, thus causing all of this damage?

sleeper06 Posted July 1, 2009 Report Posted July 1, 2009 I looked at them wrong the first time,sure got your moneys worth out of it Quote
stokes77 Posted July 1, 2009 Author Report Posted July 1, 2009 Looks to me like your wristpin clip went by by and the pin wore a groove in your cylinder Both clips were still in when I took the cylinder off. Quote
Rodneya Posted July 1, 2009 Report Posted July 1, 2009 Looks like she died from old age. 9 years is a long time to expect a set of pistons to last. Quote
