A definite improvement with a tuned motor.
"I ve used the yellow version for my mid-power build (19mm carb, 6 port barrel Proma circuit pipe) Without a rev counter it s difficult to say when the springs actually come in ( it sounds a little higher than2500 ) but suffice to say I ve got good progression and my Maxi steps off really quite quickly even with 15 stone aboard. If you have a late motor with accessible clutch, it s 5 minutes to change if you need to!" Jerry Thurston - Monday, January 10, 2022
