Poor performance under 3k RPM

Hi Guys,

So finally got to take my Versys out recently since buying this February.. winter just wont leave! Went through and did chain, clutch, throttle, and idle speed adjustment.

I noticed the motor didn't really respond well under 3K. I understand this isn't in the peak power band, but 3K and under just suck. Really rough, sluggish.


I know there are some temperature issues (people install Thermo-bobs) and it was about 65 F throughout the day. Could that be it? Or is this just how the motor is?

I'm sure there are people here that know the specifics but since owning mine I find that the Versys (compared to my CTX700) generally hits a good spot at 5,000 rpm. (On my CTX it's around 3500-4000) When I'm increasing speed I tend to combine the engine sound and feel to judge a good shifting point. I find myself in 6th gear sometimes around the CTX's mark, 3500-4000 rpm...and then I can feel the Versys lagging so I downshift.
As of late (as I'm still getting used to it) I have been cruising between 55-60 mph in 5th gear, which is around 4500 rpm. Anything above that and I'll bump it up to 6th.

IF you have a Gen 3 650 (2015 and on...) - it's just how the motor is.

LOVE mine, but took some getting used to after riding a pair of Gen 1s for seven years (THEY "pull" from around idle...!).

One of the things I loved about my Gen 2 was when I took that demo ride and she just lofted the front wheel effortlessly! I had a huge under my helmet and knew I was going to buy one. Had 30,000 fun miles on that bike.

I didn't know until now that the Gen 3 650s were a little anemic down low. Did they change gear ratios or engine internals?

Yup it's a Gen 3. Would 16 tooth in the front help? My Suzuki SV650 had this problem, turns out adjusting the throttle position sensor helped spit fuel a little sooner and made the bike much more lively at lower RPMs.

EDIT: Found some posts on adjusting the TPS. I think I'll look into doing that. If it's anything like it did on my SV650, it's exactly what I'm looking for.

My Gen 2 is not all that great below 3k and has that small shudder right at 3k. down shift one gear and keep it 3500 or above and it is fantastic.

I re-read your post several times...........my 15' 650 is fine from idle up if you are in the correct gear. You mention "rough" and "sluggish" and if you are in the wrong gear and trying to accelerate then it should/would be sluggish and perhaps a bit rough (lugging the engine). If it is more like a miss in lower RPM's then you have a problem. It's not exactly warm here yet but I have been out several time so far this year and my bike runs fine even when it's a bit cold.

Hmm I'll have to go on a ride and pinpoint what's exactly going on. But it's definitely lugging, it's just odd to me that it happens until about 3K. I don't think it's gear choice, as I understand the RPM is the RPM, the gearing just adjusts the rear wheel speed to the motor speed..

So I gather it's not a temp or TPS issue. Maybe I have to adjust my expectations and get used to keeping it above 3K.

I've noticed that if i'm cruising around 3k in town, if I hammer on the throttle it is a bit aneamic, and chugs a bit, but if I apply throttle slowly and gently it picks up, and then I can hammer it on once it gets to 4k+

If you are having a problem pulling below 3k in 1st or 2nd you might have a problem, if you are trying to lug it down to 3k in 5th or 6th and expect it to pull hard I don't think it will happen. The power band is higher in the rev range. If you are still trying to ride it in the new break in rpm range you will be disappointed. Spin it a few K more rpm and it is a whole other bike and much more fun to ride.

air filter ok? how many miles on it

if I'm answering your question I assume the basic points have been addressed, such as: did you do a compression test? is it still on fire?

I have a 2015 V650 and had the same thing I think. I have found that upgrading the fuel to mid grade or better makes the engine
much smoother and lugs lower, easier. For less than a buck (for a tankful) more next time you gas up, it's worth a try.

I reported the same thing last summer-but it is worth repeating mid grade does smooth things out and I think everyone with a Gen 3 should try it

That is your engine talking to you. 3k rpm with a smart application of throttle would seem to be a lugging situation, to be avoided as it can destroy an engine.

The motor is designed and tuned to run at mid to high rpms, why would a person not run it there? This is a rhetorical question, not aimed at any one in particular.

+1 Any attempt at hard acceleration below 3K is a bit sluggish. Took some getting used to keeping the V at a little higher RPM's, especially accelerating out of corners. Try modifying your riding habits a little and see how you feel. (Mine is an 11 by the way)

Forty years away from 2 wheel fun. Sure is great to be back smelling the roses!!!

Said it before, bit I'll say it again - on my '08 (and '09 while I had it...) I can ride around in 6th gear, down as low as 2,500 rpm, hit the throttle and it PULLS well! But on my '15 IF I try that it REALLY doesn't like it, so I GENERALLY don't use 6th much below 4,500 - to ACCELERATE...! I still ride in 6th mostly, just NO full-throttle at low speeds!

Thanks for all the input folks. Sounds like it's just the way the motor is. Again, coming from the SV650, it had fueling problems that could be adjusted away, so I figured it was the case here. I'll still get a thermo-bob and maybe tinker with the TPS, in anycase. And I'll definitely give the higher octane fuel a shot, I can spare $1 hehe.

This is my opinion, not meant to antagonize or offend anyone or to pick a fight.

While the engine can loaf just fine at low rpms, say 2500, what happens if you need a quick shot of power to accelerate out of a bad situation. Think a 4 wheeler encroaching on your lane to change lanes. A lot of times this happens, a quick shot of power to get out of their way is the prudent action. By loafing down low you remove one avenue of escape from a potential disaster. That's why I like to keep the engine where it can produce power instantly. Down shifting 2-3 gears to get power can take too long and will cut your escape time.

I'm almost always running at least 4k rpms with an occasional drop to maybe 3500.
