After years of suffering a flat spot between 4-5,000 revs its been cured by a 2p bit of wire .

Following a previous posting I got a reply from Sniffer who I am now forever in debt to

He put me in touch with a guy called Shane at B&B Motorcycles Barnsley 01226 391557

who explained that on the large mulit pin socket on the ECU there is a empty pin (top row right hand side)

simply fix a wire into this empty socket and run it to earth,he battery will do fine,

Then switch the ignition on and off three times this remaps the ECU or activates a dormant map in the ECU

either way it works a treat!

The power is now smooth all the way from tick over up with no stumbling or holding back

RESULT!!!!

Bloody maps and ECU's, cant beat a set of points and four carburettors to play with

Glad to hear youve got it sorted
