jamebo Posted November 30, 2008 Report Posted November 30, 2008 Whats up guys, had a question regarding a possible trade my nephew is working on. He's in the market for a Banshee and has found a guy online wanting to trade a Shee for his KX 250. The Banshee has Toomey t5's and a coolhead with 19cc domes. The problem is the guy says it has been in storage for awhile and it was running good when it went in, but he just went to start it and couldn't get it running without using starting fluid. The guy lives about 3 hrs away from my nephew. I'm thinking about riding down there with him tomorrow to check it out and bringing my compression tester and a couple new sparkplugs. My question is does anybody know what might be wrong with it that it won't kickstart without starting fluid? My first guess would be the carbs are gummed up, but not sure. Anybody know of anything else to look out for with it? Quote
RUDEDAWG Posted November 30, 2008 Report Posted November 30, 2008 (edited) Maybe he still has the old gas in it? May also need to clean the carbs/airfilters (hopefully). Gas in a plastic tank looses the octane rating over time. Edited November 30, 2008 by RUDEDAWG Quote
RUDEDAWG Posted November 30, 2008 Report Posted November 30, 2008 Also using starting fluid to keep a 2 stroke running is a very bad thing, no lubrication what so ever. So definitly a fuel delivery prob. Quote
2001Stroker Posted November 30, 2008 Report Posted November 30, 2008 I'm going with old gas, and carbs need a bath. Quote
jamebo Posted November 30, 2008 Author Report Posted November 30, 2008 Thanks guys, that's probably what it is. We'll ride down tomorrow and check her out. I was also thinking the same thing about the starting fluid, I told my nephew that it wasn't too good for that guy to be using that on it. Taking my compression tester too, what kind of compression should be good for sea level and 19cc domes, around 180? I was kind of scared the guy may have been running pump gas also, haven't talked to him yet but I'll see tomorrow. Quote
2001Stroker Posted November 30, 2008 Report Posted November 30, 2008 what kind of compression should be good for sea level and 19cc domes, around 180? Prolly a little less than that. I'm at sea level, and I have 18cc's on a fresh motor with 185psi. I don't know exactly what my squish is, but the piston goes up into the head 2mm's, due to the +4 crank. If it were fresh, I woulg guess somewhere around 170-175ish. Quote
jamebo Posted November 30, 2008 Author Report Posted November 30, 2008 I appreciate it, Stroker. I'll know what comp numbers to look for now. Thanks for the help man. Quote
AKheathen Posted November 30, 2008 Report Posted November 30, 2008 usin starting fluid on a dry engine was about the worst he could've done, so i would do comp. check first. after bein storred for a few years, i like to mix up a small bit of 1:1 and pour a little down the plug holes, then turn it over slowly 2x. put a little more in, plugs, and fire it up. should fire instantly. it's already primed, so you don't need to, but oil may have separated in the tank. bring fresh gas, new plugs and some carb cleaner to clean the bowls. good luck :thumbsup: Quote
jamebo Posted November 30, 2008 Author Report Posted November 30, 2008 We went down there today, tried unsuccesfully to start it. The guy started tinkering with the carbs with a screwdriver saying that all it needed was adjusting to run. At that point I went to the truck and got the compression tester...... 48 left cylinder, 140 on the right. No deal Apparently needs a new top-end and who knows what else. I sure am glad we took the tester down there, he had originally told my nephew that it ran good. At the last minute changed it to "well it was running fine when I parked it but now I can't get it started, I think the carbs just need adjusting". Thanks for the replys though, guys. I wish it had only been the gas or carbs. Quote
2001Stroker Posted November 30, 2008 Report Posted November 30, 2008 48 left cylinder, 140 on the right. DAMN! How the hell did the left cylinder get down that low? I'm guessing hole in the piston. Quote
jamebo Posted November 30, 2008 Author Report Posted November 30, 2008 DAMN! How the hell did the left cylinder get down that low? I'm guessing hole in the piston. That's along the lines I was thinking. The guy didn't have much knowledge of it and kept talking about the Blaster he used to have. For all I know he may have run straight gas in it or low octane fuel. After we saw the engine needed work we didn't stick around. My nephews KX runs awesome and he didn't really want to trade for a machine with a blown engine. Quote

Your right, after the compression results 3 to 5 hundred would have been a good offer. Quote
