OK, I'm nowhere near the level of some you guys (but I'm trying).
Here's my problem with my '97 XX with about 13K miles on it: Upon startup this spring, it runs like shit!! Last ride of last season was fine. This year, it was very hard to start (1st time ever). Once it did start, I had to leave the choke open to keep it running. (despite potential plug fouling). When the bike reaches full operating temperature, the choke has to be left at about 1/2 postion. This will get the idle around 1000 - but it still sounds weird. Moving the choke even a hair lower causes an immediate engine stall (no sputter - just dies instantly). I filled the tank with fresh gas and took it for a little ride. When it's on the rode and the throttle is open, the bike stills run like one mean machine ( you gotta love a bike that runs great even when it runs like shit !!) So I decided to put new plugs and a new air filter in. While they were needed, the problem remains identical as before. So today I removed the tank and filter box so i could see the carbs and choke slider(hooked to carbs). The Choke lever from OFF to 1/2 position does nothing (almost no resistance on choke lever and no movement of cable at the bottom end). I don't remember the choke lever ever feeling like that before but it appears that moving the lever from 1/2 to full open does work the choke through the full range. I base that on the fact that on the choke slide bar(at the carbs) there are 4 slots (one for each carb) that have a screw threw them. The lever being moved from 1/2 to full open moves the bar from one extreme end of the slot to the other. (which makes me think that there's no cable adjustment problem like I originally thought). The lever action still doesn't seem right though-especially since moving the lever below 1/2 cause a stall! Anyways, now I'm thinking the carbs may be the problem but I am NO carb expert. Could old gas have gummed something up in one or more of the carbs? Pulling the carb, cleaning/rebuilding, and resyncing them is beyond my "comfort level". The only local NON dealer mechanic is out of business or I would have taken it there to begin with. My local dealer is a well known crook and that's why I decided to start the project on my own. DOHH!
I'm stuck trying to decide which way to go. If I should put most of the bike back together and run something like SeaFoam through the system and that doesn't work, then I have to tear it all apart again and try the carbs. While the extra wrenching isn't a big deal, the fact I may have to get into carbs could be. If anyone has read this without falling asleep and is familiar with the carbbed version of the XX, I'd love an opinion on what the problem even is (besides me
Thank God I've got an 1800 VTX to ride while I screw with this!!
