sv1000sz fluctuating power
 

I've been noticing for a while a power fluctuation in 5th or 6th at 70/80ish mhp, its feels a bit like an old 2stroke about to heat seize and then releases on and off, its very gentle and random but very annoying.
Any ideas what the cause could be? :confused:

Can't remember what the revs are in 6th at 70/80 on a sv1000 - is it about 3-3500rpm?

If so, I would start with throttle bodies - may need synching...

I had this on my SZ after adjusting the TPS to the guide on here. I put it back to where it was and problem went away again. It can sometime feel a little hesitant at 5000 to 5200. May be worth chatting to svracer and arranging to have the ECU re-mapped including TPS setting. They use something better than the Yoshi box and have loads of experience. Only wish I was closer to them to do the same.

How do you like the bike ? They are a gem. Too much character for many but I love it.

Personally, I reckon he should get some pictures up with his new exhausts! ;)

If the sv1000 is mapped anything like the DL1000 i just got rid of then i got rid of the dreaded chudder by getting the throttle bodies balanced and the richening the idle circuit with a yoshi box by about 1% this made it absolutely spot on and removed the lumpiness.

It is the paint scheme, causes the bike to hesitate because it thinks it's a Gixxer! Lol

as is said above, it is either TPS or maybe you got an air filter that is too dirty/too restrictive as cruising at 70/80mph (4,500rpm) the engine needs quite a bit of air, but, is not pulling as hard as when hard on the gas.

fearing that ask on "the portal" too
