badassbanshee479 Posted October 12, 2006 Report Posted October 12, 2006 friend of mine has a 89 framed banshee with a 97 engine. over the summer he washed his bike after a weekend ride and parked it. this passed week he pulled it out to get it ready to go up riding this weekend and it is braking up real bad on the top end and it will not rev all the way out!! we have changed the plugs cleaned the carbs, put a richer main in it, checked the flywheel for broken magnets, checked the air gap on the pick up coil, checked al the conctions, it is a stock engine other than a timing plate at +4 and t-5s, I am gonna ohm the stator to night and see if thats it, if not I am gonna try my cdi box and coil. when we pulled the plugs one is brown and the other is black and wet. you guys got any ideas??

Bansh-eman Posted October 12, 2006 Report Posted October 12, 2006 well obviosly the black side is rich and fouled out... make sure the carbs are seated all the way in so you dont lean the other out... there was more then likley no need to go bigger on your main, that controls your top end, if anything your pilot needed to be changed and/or your needle clip Quote
badassbanshee479 Posted October 12, 2006 Author Report Posted October 12, 2006 I think I said its breaking up on the top end, and I know that side is rich Quote
Bansh-eman Posted October 12, 2006 Report Posted October 12, 2006 I think I said its breaking up on the top end, and I know that side is rich wow once again my skimming over read method failed me ... i didnt see the top end part .. so now i feel like a ballsack, umm sounds like you covered the things i thought it would be... is it cutting out like electircal or like is being starved for fuel?

I have cought my self doing that a time or too, no big thing man thank you for the help though. I think its electrical, dont sound like detonation from lack of fuel. I am gonna change out the plug caps tonight when I head back over there. Quote

I am gonna change out the plug caps tonight when I head back over there. if it is electrical its usally only casued while its wet but after a week everything is dried out and should run normally, now this is assuming the water from washing it is casuing the electrical problem and not the life of an electrical component going out. also did he wash it and start it back up after wards? if so maybe he got something wet enternally and casued a short? but that dosent explain it only being top end..

dajogejr Posted October 13, 2006 Report Posted October 13, 2006 Got a spare CDI off my 96 you can try too...but, it's a different harness. Leakdown test it yet JT? Small enough air leak will cause it to break up in the higher RPMs, normally won't cause idle or lower RPM issues.... Start it up, remove the flywheel side cover, let it warm....and spray the piss out of the intakes, bottom of the jugs and in behind the flywheel with carb cleaner... If shee dies down a little....bingo. Quote
Ducman Posted October 13, 2006 Report Posted October 13, 2006 Gotta be electrical. Try cleaning the spark plug wire connections. Stock wires are pretty crappy and get a lot of corosion unless you use a lot of dialectric grease. Also since you said one plug was black and wet and the other is bown makes me think the problem in not in the CDI or coil pick up system since both plugs always fire at the same time. Quote
locogato11283 Posted October 13, 2006 Report Posted October 13, 2006 sounds like what mine was doing. swap the coil out and make sure its grounded good to those tabs and see what happens...it fixed mine immediately.. Quote
badassbanshee479 Posted October 13, 2006 Author Report Posted October 13, 2006 switched out the plug caps, no go! started lookin over the cdi box and found a big crack in it, and the side of the box around the wire loom is all cracked, thinkin this is the problem so now I am in search of a cdi box with the old school plugs on it, so anyone in the MI area that has an extra one please get with me asap, this guy is tryin to go ridein this weekend. thanks for all the sugestions guys, also if you dont think this is it please let me know.

dajogejr Posted October 13, 2006 Report Posted October 13, 2006 My CDI is cracked too....and I thought it was bad....it wasn't.... if you can find one with a newer style wire plug for it...give it a whirl.. 97 and newer are the same.... Quote
