I have a 1994 Kawi Bayou 400 which had been running well until it sat for about a month. I left the carb dry while it was park and the temp had dropped below 0C in this time. Pulled it out last night to go for a ride and it fired up just like it should but noticed when I started to head down the road I could hold it to the bar and it didn't seem to accelerate. Lower gears weren't as noticeable but 4th and 5th it just seemed to have no acceleration and half or full throttle made no difference. if I tried to go into 5th gear with any throttle it would stall. I turned around and just poked home very slow and it seemed to stay running but this was between 15 and 20 km/h max.
I have taken the carb apart and it appears to be clean and nothing stood out on inspection to have dirt or ice. Is there something I should dig more into?
I have checked the plug and it appears to be sooty with easily rubbed off carbon. I plan to get a new plug today and test.
compression with the throttle wide open is 175 psi.
I have opened the drain plug in the exhaust thinking there could be a mouse in the exhaust or something but no difference.
I do find the engine is tickity compared to my 2000 Honda but I am not sure if this is just me looking for issues or if it has always been this way.
If anyone has any insight I would appreciate it.
In the last 6 months I have done new oil and filter ( mystik synthetic)
new Peak RPM CDI
I have noticed the fan comes on more often with the new CDI, could this be a program thing?
The quad has done this off and on, almost since new, but it's gotten worse this year. Sometimes if I freshly charge the battery, it'll work fine, others times that won't matter. Turning the key to on it sounds like it's connecting as I go to the start position, slightly before the full turn, but it's not like there is just a sweet spot to find, it's totally erratic.
Now the battery is basically dead so I put a new, slightly bigger AGM battery in today to replace the factory one with all of 800 miles on it, but those have lots of plowing hours included.
I was able to get it started once, but it still went into limp mode after just a few moments of driving it (that's another topic), so I put it back in the garage and started probing around. Now it doesn't even try to turn over.
Is an ignition switch, the $18 shipped aftermarket variety on Amazon worth a shot? Or should I go straight for the starter? The new switch may not come for over a week, so I hate to just put my hopes in that if I'm missing something obvious. Fuses are good, so it's not something super obvious.
After purchasing a lightly used 2018 570SP (300 miles on it) I noticed that the display was flashing on and off. I remember reading awhile back that this was a common problem on the 18 model. I can't remember what the fix is. It also turns over slow even though the battery is charged. Anybody know what the fix is on this issue?
Customer brought in this bike for no response when put in gear. After getting into the transmission I found the main shaft for the clutch had been stripped where the gears mesh up and also the shaft for the gears had been broken in half. I replaced all broken parts and reassembled the transmission. Now it makes a knocking noise in low gear and in reverse. When in neutral it tries to roll reverse while making the same knocking noise. I’ve disassembled and reassembled it several times with the same result. Any ideas??
