Hey I'm new on this site. Site looks great, its well organized, and congrats on 1 mil posts.
Anyway - real reason why I'm here...
I just purchased this Banshee.
Supposedly an 89
Stock pipes, aftermarket air filter, aftermarket / different plastics ( maier plastics, 'ceet cover' )
So I purchased it knowing it needed work. The guy thinks the one cylinder is bad.
However I do not think this is the case! I have not removed the exhaust to check for scoring. I will do a compression check tomorrow - but I like getting input from people online because you guys usually have some great ideas because your way more experienced with the unique systems of Yamahas Banshee platform.
So my experiences with small cc toys lead me to believe the first thing I should do is get spark. It was non-existent at first.
Symptom definition: starts in one kick, just doesn't rev out correctly / quickly. Weak spark on one side. Lots of smoke
--if you care to read what I have been dealing with for an hour or so --
10 minutes went by. I knew unplugging the key switch & kill switch could be a fix. No bueno. another 5-10min I was jumping the key switch wiring. Then I find a ground by the front right headlight disconnected. Then I have read up on this T.O.R.S system. So I unplug those - screw around. I go to kick and I get spark. So I call my friends and let them know ( they were just with me when I picked it up ) and the next time I go to kick it - NO SPARK! Disappointing. Poking around another 15min I rigged the Tors system incorrectly and I tried fumbling with the CDI box ( came with another one )
Previous owner replaced the flywheels coil setup but he doesn't seem too competent - even though somebody used a bunch of dielectric grease on the connectors ( I like that stuff )
with more Tors bypassing & ignition jumping I got spark I noticed one lead / plug was getting lesser spark.
Checked the carburetor tops - the one was loose
Anyway I slapped the tank back on and drover er around!
Both lights work ( brake light doesn't - probably bulb)
Pulls really slowly ( sprocket set is 14/42 - stock )
I noticed on the cyl with the weak spark that the rubber upper pipe mount is kinda wired together ( will fix that tomorrow ) so that could cause some problems.
There is just tons of smoke coming out of the silencers ( stock pipes / silencers )
I checked the fuel before I ran it. Its red/ pink colored oil!>!!?? amsoil ?
I never did unplug the TORS box next to the ignition coil !
I could check the pickup gap on the flywheel as well! never did.
Cliffs:
New banshee!
Smokes like crazy!!!
One side has weak spark, also had loose carb cap, bad exhaust mount causing a small leak
compression check tomorrow and carburetor cleaning / adjustment
previous owner has strong / weak points in his methods ( stripped screws grr )
PO replaced coil assembly, put an aftermarket air filter on.
Wiring is kind of taped up here and there.
2 cdi boxes. That both produce same weak spark on one side.
Going to swap another ignition coil from my friends Shee tomorrow as well.
Resistor or non resistor plugs. What about spark plug wire ends? non-resistor?
Place your bets people?! Whats wrong here!
If I don't have to do any motor work - I'm doing good here.
