ok heres the deal
1st off I did some mods to my 02 banshee last summer...
I put on a boost bottle
Jetted one size up
K&N filter and prefilter
removed shorkel
last summer this thing was very fast, these mods really opened it up.
over the weekend I went to ride it (first time in cold weather, less then 40*F, with the mods)
First off when I started it black water looking stuff was comming from the tail pipe, looked like oil.
Also it wouldn't idle so I had to adjust the idle up on the carbs
then it kept smokeing, like it does when you first start it, only it never stopped after it warmed up, the whole ride it was smoking like crazy
after about 1.5-2 hours of riding I ran out of gas, normally (even after the mads last summer) I can go at least 3 hours or so
also I kept fouling out plugs.
I'm not sure if the oil:gas mix is right, last summer I ran 28:1 and it ran good, and hardly ever fouled out plugs.
some background on my mix. my bike is from canada and the owners manual says to run 24:1 but everyone I talk to in MI says to run 32:1 so I met in the middle. in the past this has worked fine for me.
also to make things wose it was backfireing and about 1 out of 5 throttle pushes it was real easy to push and the engine would rev real high. this makes no since to me. also the throttle cable recentaly broke and it has a new yamaha throttle cable on it.
well thats all I can think of, any info would be greatly aprecieated. I have no clue what to do from here, I'm thinking about putting it back to stock, but I really liked how fast it was last summer.
thanks in advance
oh yeah I forgot to mention, I topped off my coolant before riding, I filled the overflow jug compleatly. I dont think this would make a diff, but thought I'd mention it.
