Ok so Ive notice that when I in 5th or 6th gear and traveling about 65-75 Mph. if I give it very little throttle to try and speed up and if I get to 7000 rpms that the engine revs up to about 8 or 9 and then will level back down after a few seconds and it will gain some speed after that.
Im not a mechanic but it doesnt seem like this is normal behavior. Any thoughts
Clutch slipping/Need adjustment?
Do you have enough free play in the clutch lever? Should be 4mm.
How many miles on the bike?
23k miles, about the clutch stuff I have no idea! Im a newb and not a gear head, I have a friend fix all my bike problems but hes out of town.
Your clutch is definitely slipping. Might just need adjustment, or it could be worn out.
the lever?
The lever is one point where adjustment can be made. See this thread for the full clutch adjustment procedure: http://gstwins.com/gsboard/index.php?topic=58383.msg662634#msg662634 .
If that procedure doesn't work, then the clutch plates are warn and most likely need replaced.
Did you change the oil recently? If so, did you make sure to use an oil without friction modifiers?
my bike cruises at 7k rpm at those speeds...in 6th...
I did change the oil and I dont know what kind of Oil I used, Ill check it though
Make sure it is NOT car oil (5W30, 10W30). Those have "Friction Modifiers". 10W40 is the best.
Some 5W30 and 10W30 do not have friction modifiers in them, but most do. Look on the back of the bottle of oil. Near the bottom there is a circle with some certifications in it and if the words "Resource Conserving" are in the circle, that is bad for wet clutches.
it was not car oil it was castrol 4t sae 10w-40 motorcycle oil
You should be ok on that then. Go ahead and do the clutch adjustment from the thread I posted and see if that fixes it.
ok Ill give it a go in the morning, it doesnt seem to terribly hard to do after reading the thread but Im seriously not a gear head, is something I should try on my own or wait and let my buddy help me? can I screw it up? reason I ask is its the only method of transportation I have right now so if I screw it up Im Stuck until I can get a pro to rescue me
If there is one thing I've learned after browsing forums, it's that any job CAN be screwed up. If you don't feel comfortable and it's your only mode of transport, you might be better off waiting. That being said, this is on the simpler end of wrenching. If you can change your own oil, you can most likely follow these instructions without a hitch.
I did change my own oil! and this one time I did wipe my own ass! so Ill give this a shot too. I want to get to the point where I can do the little things on my own. worst case, I skip class tomorrow! and thats really never that bad!
