The engine break in procedure is soon finished, time to tune my car!



here the species
1293
Clubman gearbox
MED clubman S/C and S/C drop gear
SW5
1,4 swiftune roller
twin HS4 and swift une ram pipe and ABD needles
fully ported head
switune CSI etc..
The car runs well but it's like ON/OFF when you push the slightly the throttle
I guess the damper ascends too fast
I check the damper spring but no color mark on it, my carbs are FZX3054 so should be blue or black damper spring?
Thank you for your help and recommandations
