Just tried the map, it didn't port so well over to an 09 vin map lol so no go there. What about Tps sensor being slightly off?

If your air filter seated correctly or your air box not seating correctly on the inlet to the mainfold

I get a bit of that, did the map solve it for you?

So why would it snatch like that. Too rich too weak on mixture?? Or simple not enought back pressure ??

Hi tango, yeah I've looked at the 05 06 aftermarket map last night, what I've done is copied the tables across to my 09 vin map so the values will be the same in a 09 format map. I'm not at home till the end off the week, will try it when I get home

There are no error codes at all, stock map doesn't work well with aftermarket pipes.

Guys please help me! Ok I feel a little better now, I shall explain I have a sprint st 1050 2009, about 6 months ago I installed trident exhausts which sounds fantastic, so I pulled out tune ecu, put the correct tor map into my bike, reset the adaptions correctly as described in the manual, and went off for a ride. However if you roll off the throttle and try to roll it back on between 6000 and 4000 rpm the bike won't power back up, it just hesitates then snatches back in as you open the throttle more. So that's the outline of my issue, Since then I have tried all sorts, I have reset the adaptions again by using tune ecu and the 12 min tune with out tune ecu, I have tried disabling the O2 sensor, I had moderate success using the b69 map from the tune ecu page however that is a custom map and my bike won't idle properly using that. I have tried the redundant maps that the current one replaced, no further success. I'm at the point now were I want to rip the tridents out and put my standards back in, god knows what it's done to my bike! Only think I was thinking today was maybe its a fault O2 sensor? Guys please help Thank you

ill definatly try the towel, its not a pinking noise its more of a dull knock, like a cowbell thats pretty much exactly how it sounds, like i said ass soon as the revs raise a couple of hundred it goes away its odd

thats what i think megawatt because its not in any pattern or rythem but you know how it is, you always dream up worst case in your head ill get a video tomorrow or friday for you guys to cast your eyes over

could be like u said megawatt good idea ill check that out tomorrow too thanks

thanks for the responses so for guys, yeah it only happens at idle ill try and get a video up tomorrow morning, its coming from under the tank i engine, goes when ur riding because its not idling anymore,but if you freewheel with the clutch in and its still cold u can still hear it etc,

haha dont say that mate ull curse it!

Hi all got a sprint st 1050 2009, and ive been trying to fix a noise thats appeared on it for nearly 2 months now and had no joy, when you start the bike from cold it makes a knocking noise the best thing i can compare it too is a cow bell knocking, its in no rythem or order as soon as you rev it up or when the bike is warm it goes, its just really really annoying me, ive tried the obvious like n checking for loose parts etc , ive changed the oil and filter, just done my best to work it out but cant get it, it also doesnt make any odds whether the clutch is in or out ether, thanks for your help guys im sure someone will know.

Fork oil replaced still no goof guys any more ideas I'm stuck now

how do i check the for allingment, the oils never been done i had the bike since new..
