Hey everyone,
When I'm on the freeway and I try to accelerate by opening the throttle up quite a bit (all the way basically) and bike will rev like its in neutral sort of and have no power really. When i ease on the throttle i don't have the problem. What do you guys think? Vacuum leak? Bad clutch? Carb clean? Lube throttle? Thanks :thumb:
Sounds like clutch slip. If it was your carbs the bike would either bog down or break down as if it was running out of fuel.
Clutch slip probably. Standing still hold the front brake tight, rev the engine to 2000 rpm or so and slowly engage the clutch. If clutch isn't slipping it will kill the engine.
Clutch slipping means replace clutch right? Thanks guys, that's what i was thinking but definitely didn't know how to test it.
Maybe, could be a cutch adjustment problem or use of energy conserving oils with friction modifiers.
Do you mean reducers?
It could also mean your clutch cable is too tight on your clutch lever. Supposed to have a little bit of play when you pull on it. I learned that by tightening my clutch lever all the way because it rattles on my z1000 and then I developed the same symptoms you have. Put it back to having the play and it went away.
I'll definitely try that harding, cause it does feel super tight and the clutch engages really late. Thanks for the info.
Far too many people are not even aware of the need to check the rough adjustment 5&6 in this image, even if your lever has the correct play...the rough adjustment could be keeping the clutch engaged (slipping) I post this photo at least 3 times a year.

Adjust your clutch properly at all 3 places and then test for slippage, that's what I meant by clutch adjustment problem above. Fixed oil typo. :icon_lol:
First thing to do is to properly adjust your clutch in all three places. First turn in the thumbwheel adjustment at the clutch lever all the way and lock it. Then loosen the locknut at the cable end going into the sprocket cover housing and turn it in a bit to slack cable. Then take off that little flange shaped cover on the sprocket housing and adjust the pushrod freeplay there. Turn the screw in to touch the rod and back it off about 1/4 turn for proper clearance and lock down the locknut. Then make final clutch freeplay adjustment at engine end of the cable. The thumbwheel adjustment at the clutch Lever can then be used for future minor freeplay adjustments.
I'll be sure to do that everyone, thanks for the good info. keep it comin'! :thumb:

Steve, that photo is from the Suzuki Shop Manual but you omitted the first step of turning the adjuster at the cutch lever all the way in so that when the final clutch freeplay adjustment is made at the engine end of the cable the full adjustment at the clutch lever end is left for future freeplay adjustments.

Thanks gsJack, I just stole your picture, so now mine is correct :thumb:
Maybe at the time I didn't think the first step was important??
does it do this in all gears? or just one? if you have a bent shifter dog you could be having gear slippage. doubtful, these trannys are built... overbuilt.
adjust clutch and change oil first to be sure.
I believe it happens in all gears, haven't really tried fully opening throttle in first. Changing the oil sounds like a good idea i will probably do it in a couple weeks when i am about to start riding it every day.
