What would be good enough 60 or 40 only mods im going to have is ported intake and i got my endcap mod

 

40% is enough for that, but the feel of the clutch lever between the 40 and 60 is pretty insignificant so if you plan on anything else down the road might as well get the 60 now.

 

i had the 40% and they seem to go after time, i have the red springs from tvi and put them to a pretty good test, i launch at about 7-8 and they have lasted 2 years and have had nitrous hitting on them for the last 9 months.

 

I ordered the 40s.. got the 60s, haven't had a problem with them and the lever pull is ok.

 

I run 60% and the pull on the lever is hardly noticible after a couple of rides. We ride for many of hours on long trails and it have never been a problem. My friend has 60% on his DS and didn't notice much difference at all.
