Alright, when I first got my 650 csr, I noticed that during WOT it felt like it wasn’t at full power, and it would randomly kick in (you could see how that would be dangerous) and while idling it sounded a little rough, but it would stay alive. It also liked to backfire.
So I took off my carbs, cleaned out the jets, put it all back together, and the idling sounded much better’ That was until I put the choke back down and the bike started struggling and eventually would die. It would start up again, with the all the way up, and I would have to get going then put the choke down, and it would be really hard to get going during 1.5k-3k rpm’s, but once riding it felt smooth, WOT felt a lot better, but sure enough every time I stopped, it would just die.
Here’s some key notes
1. I do not have the airbox on at the moment, because the boots are harder than diamond so there was no way of putting it back on, and I didn’t want to buy pods and rejet the carbs, so I currently have the boots soaking in isopropyl alcohol and wintergreen oil to soften them up, then hopefully be able to somehow squeeze it all back together
2. I cleaned out my tank out as best as I could and put fresh gas in it.
3. I’m not particularly sure the settings for the air/fuel mixture screw. I also hope I’m tightening the correct screw (in the picture attached below)
4. Just recently, when it would die, it wouldn’t start back up. I’m assuming it’s a battery problem since it sounds nearly dead so I’ll charge it in the morning, but in case it’s not, I figured I’d mention it.
I know I probably shouldn’t have driven the bike without the airbox, but I’m still learning all of this and I was very anxious to see if I fixed the idling problem, which initially it sounded like I did, until it died.
Personally, I think it’s a combo of the no airbox, and my air/fuel mixture screw settings. But I’m new to this so I don’t know
Any help is appreciated. If it means anything, I’m at about 4,500 ft above sea level.
Thanks!
