primary gear

i have an old p2 with malossi 210 fitted, a simonini sports exhaust, si 24/24 carb .would i have enough power to pull the malossi ultra long primary gear i.e.24/63

thanks alex ,i did mean old p125 gear,sorry

sorry,I saw you already have the short 4th gear in.
you put the gear of the T5 into the old gearbox of the P2?

this should not work.

you need the 4th gear of the P125.

if you are 50 kilo light yes, if not then only in combination with the short 4th gear of the old PX125.
the step between 3rd and 4th gear is ok then

cheers alex
