1996 T595 Flat Spot When Pulling Away

Is the bike exhaust standard, may need tuneecu to change map to suit the can, worked on my t509.
Have you looked at the 3 vacuum pipes to the injectors, any leaks or breaks?

 

Sounds like running very close to too lean at idle , and leans out when throttle is initially opening !
I'd look at following
1 inlet rubber cracking !
2 vacuum piping and cap's
3 diaphragms in carburettors
4 simplest of all raise the idle ?
5 more difficult - idle jets blocking up or floats out .
6 adjust/synchronisation of carburettors.

Just a few quick thoughts

No carbs capt, it is fuel injected.

 

If he changed the map when he fitted the can but didn't change it back after putting the original back on, yes it can and does make a difference. There are maps on tuneecu for most systems, if you ask in the tuneecu forums I'm sure you will find the best for you. You need a lonelec lead and tuneecu app or ask a mate and use theirs.

 

1 ,2 , & 6 still apply , just in a slightly different manner.
And 4 could be a simple temporary work around if 1,2 & 6 don't sort it , until you do find the actual cause.
