Bike is running Rough!

Postby Santa8T » Wed Jun 17, 2009 10:51 am

So I just started changing my own oil (not too tough and glad to save a $100 doing it). The first oil change went great for the first 1,500 miles, then I noticed the shifting got really dificult in the lower gears and the bike started running rough on the freeway in higher gears after about 30 min on the road. So I figured I probably shouldnt have gone with the 5w 30 oil. So I changed my oil again but this time I used the regular 10w 40. It started riding very smooth again and I thought the problem was gone. Well I was on the freeway for about 30 miles, 45 min (its LA traffic) and as soon as I hit the local streets, my bike was running even worse than before. Shifting in the lower gears was almost impossible, the bike would stall at every stop, it was getting pretty dangerous.

Now I know everyone talks about 2nd gear going out, so Im wondering if this may be the case? 1st, 2nd, and 3rd is where Im having the problem. Its basically acting the same as if Im in dire need of an oil change. Also when the clutch is fully pulled in at a stop light, my bike is still trying to move forward.
Note: The bike runs perfect when its still cold and the problems only begins after I've been riding 20 min or so.

So if anyone knows what the problem may be and what the cost to fix it may run me, I'd really appreciate the advice. Also, here are the items I used in the oil change, if it helps.

YZF600r 2004
Castrol Actevo X-tra 4T SAE 10w-40
K&N Oil Filter 303

Im at 16,500 miles only as well

How much have you ridden this season prior to changing your oil? I haven't had any problmes with my bike because I bought it new a year ago but, when I've had problems with other, older bikes, I'd dump a can of Sea Foam in the gas tank and run the tank down to almost empty and then fill up with high test a couple times after that and that helped a lot (most of the time). That might help with the rough running of the engine but not sure about the shifting problem. This may not help you but it's the only thing I know! :o And it's a cheap fix...sometimes.

Well I took all winter off from riding, went about 300 miles then performed my first oil change. After that the first 1,500 was fine before the problem started. Changed oil again, ran fine for 40 miles then problem was even worse. Only happens when engine is pretty warmed up. It runs as if I haven't shanged the oil in 7000 miles.

I have never used the oil you listed, but where did you buy it? It it made for bikes with wet clutches? Is it energy conserving?

yes it is suppose to be great for bikes with wet clutches. Its also suppose to be use for heavy stop and go riding. I just drove to my local pep boys for a fuel/carb cleaner and my bike was failing within 5 min now. The stop and go is killing me. It stalls and shakes at every stop now.

You mentioned that the bike still pulls forward when the clutch is pulled in all the way. You may need to adjust the clutch free play. There are two places where you can do this. 1) at the lever (this is where you want about 3/4 inch free play and I usually check this first) 2) under the sprocket cover ( if lever adjustment doesn't yield satis factory results; this adjuster is under the black plastic cap.

Search the forum there was a thread posted about this recently with links to the How-Tos. It may not be the oil at all.

Also make sure that the oil level is correct and the you didn't over fill the oil.

Yeah Im trying to find out right now the proper way to adjust the clutch, in both spots.

Also about the oil.. The bike takes 3.09 Quarts of oil. The bottles come in 1.05 each making it 3.15. Is that a big enough difference to even matter? I checked the levels once the bike was warmed up and the oil line was right in the middle of the viewing spot.

Sounds like your good on the oil & the # of quarts you put in. The bike when full will be just below the top of the window, but you cant get it right (unless you measure it out) I have always guessed and kept an eye on the glass when bike is level.

It could be the clutch, the fastest way to check that would be the top adjustment. Just screw the knob all the way out and see if the bike still acts up. If you dont have room to do it @ the top work your way down to the bottom.

You did get a new fuel filter? Have you changed that yet? I dont think a dirty filter would make that much of a difference, but might. Its likely something pretty simple, just have to find it. :doh

Does it crank good, strong battery?

Yeah its starting up great, no problem, and it runs fine till warn up. I adjusted my clutch in the casing (hopefully I did it right) and the cable. I haven't driven it yet, but will before the end of the day. I'll follow up if anything changes.

The oil filter is new. It probably is something simple... Hopefully :dunno

Thanks for all the info everyone. If anyone else has any other ideas, or have dealt with the same problem in the past, please feel free to give your feedback
