S2R 1000 flat spot

[zedsaid]

solution:

Downshift

the bike doesn't have a flat spot

it isn't making any power at 3K

fixed it for you.

He has GP shifting and is terribly old so he forgets things. Thank you for fixing.

In the tech section you will find a number of posts about this same issue with other S2R 1Ks.  If it's a lean run issue, new higher flow cans won't fix it.  You cant' map this ecu either, so that's out.

Some people disconnect the O2 sensor, that seems dubious (to me), and there's a thread on an O2 sensor manipulator (best option in my opinion) and it seems to get good press.  Good enough that I went ahead and ordered it.  We'll find out if it's worth a damn shortly I suppose.

not a real fix, but this is so easy to ride around.

slip the clutch in traffic, and cruise at 4k plus.

Ok I got it... I was afraid the cold engine doesn't like 4k

If the bike needs more rpm then just drop a gear.
Slipping the clutch will just result in expensive fixes later on.

I meant in first gear.   I haven't had clutch issues since starting street riding in 1989. 

clutch slipping in traffic at slow speed first gear is not a problem.

Oh OK - thought you were advocating it in 2nd and 3rd.

only to bring the front end off the ground...and that's not for the new guys thread.   

(nothing feels better than a nice second or third gear wheelie when you're feeling down)

that and I never understood why you would

"downshift" into a "higher" ratio gear

and

"upshift" to a "lower" ratio gear

I like my way better

So we should start in "6th" gear and downshift our way to "1st"? 

But then it gets confusing for the people who only have 5 gears.

I'm confused already

but

I've only got a 5-speed

:-\in other words, shifting up and down is about the name of the gear, not the ratio, or direction your foot moves to get it from one to the other.

I get IZ_, sleep deprived

Time to ride home.

The S2R engines seem to live better over 4K.  In fact, I think my bike isn't even working (or awake) until 4500.  It seems that it's much easier for the engine to handle adjustments in throttle input from there on up.

I recall reading a member post about "lugging" the engine.  While it's not great for the engine, it's good to have a good feel for how much (or how little) effort the engine uses to propel the bike forward.  I.E., if you're lugging along at 3k, and you need to do a quick suburban maneuver to avoid a traffic situation, the bike might not respond as easily as at 4500.

Think of the bike's engine less like a car's engine (where 3000 would be considered high even for highway constant speeds).  Just try to get a feel for how effortless the bike feels as you make demands with the throttle.

A twin's sweet spot will be different from an inline four (sweet spot well over 8000, for example).  My GS's sweet spot is 4000 constant speed, the S2R's is 4500 ish and up.
