04BRAAP Posted November 18, 2015 Report Posted November 18, 2015 Your advice is appreciated . What's up fellas, I was at the dunes this weekend and and I let someone borrow my bike . During the trip the bike stalled and it would not start anymore so it had to be towed to camp. When I got home I took the plugs out and noticed the left plug had melted aluminum on it . Oh oh!. Did a compression check on the left piston and it had zero compression. Did a test on the right one at it had 148. I took the cool head out and it looks like the piston melted a bit or a lot !. Any idea what could have caused this and what can I do so it won't happen again?. And what would you recommend I do. Should I go stock again or are there some mods that you would recommend . 2002 banshee 91 octane mixed 32:1 on castor On engine ice Cool head with 21 domes 300 Jett's at glamis and 320 in Arizona TORS delete kit with FMF pipes Br8es ngk Sent from my iPhone using Tapatalk Quote
04BRAAP Posted November 18, 2015 Author Report Posted November 18, 2015 Where ?. I had done a leak down test prior and it held 6lbs for 5 minutes . Sent from my iPhone using Tapatalk Quote
04BRAAP Posted November 18, 2015 Author Report Posted November 18, 2015 New Jett's were installed (300). So you think I should have stuck with the 320's I use in AZ ?. Sent from my iPhone using Tapatalk Quote
04BRAAP Posted November 18, 2015 Author Report Posted November 18, 2015 most of the time when 1 side burns down the issue tends to be located on that side. whether it be air leak or carb issue among other causes..... The odds of it bruning down like that from being lean are unlikely as BOTH cylinders would of paid the price if that was the case. Doesnt matter if jets are new or 100 years old.. if there's any dirt floating around in your fuel or if anything fell in there while assembling.... it would of shit the bed like you see That what I was thinking . Why did one burn and not the other . Thanks for the knowledge . Any recommendations ?. Should I upgrade or keep it stock ?. And what would be a good bump in power if I still would like to use it as a trail bike and ride some bowls at the dunes every now and then?. Sent from my iPhone using Tapatalk Quote
04BRAAP Posted November 18, 2015 Author Report Posted November 18, 2015 Thanks for the heads up . I forgot to mention I do currently have first gen vforce reeds suspension is definitely next after I get this girls back on her toes. Any recommendations for pistons and a port job ?.

trickedcarbine Posted November 18, 2015 Report Posted November 18, 2015 Did you leak down before you tore it apart? Not normally how I do it, but for a guy learning it's a pretty good way of determining what went wrong. Quote

trickedcarbine Posted November 19, 2015 Report Posted November 19, 2015 I am not usually one to do a leak down, but if you are still pretty new to wrenching and diagnosing 2 strokes, it's not a bad idea. It could show you if the motor suffered an air leak if you don't know what to look for. But like zilla said. A single side failure like that would usually be from a lean out. Was the bike idling kinda high or slow to return to idle? Quote
04BRAAP Posted November 19, 2015 Author Report Posted November 19, 2015 I got my TORS delete kit installed and when i got it back the return to idle was high . I also noticed that I had to pull the choke out to start it when asked before I didn't have to it would always start first kick Sent from my iPhone using Tapatalk Quote
trickedcarbine Posted November 19, 2015 Report Posted November 19, 2015 Potentially not sealed up after the new top end. Quote
