Hi guys
I was wondering if I really need the 60% stiffer springs. I dont ride all that hard, the occasional drag race on the highway and some trail riding and gravel pit racing. My clutch started slipping after I put the hmf pipe and the K&N filter on it. the bike does have 4000+ miles on it now so I guess something is going to wear out. But I was just wondering If I need that stiff of spring. Any help would be great thanks to all.

 

You can always alternate the springs. one 60% and then a regular and so on. that may be enough.

I wouldn't, to me 40% is about right. The 60% have been known to cause the actuator shaft to strip teeth plus it has a very heavy clutch pull. The best set up is a Barnett clutch pack + the 40% stiffer springs.

 

I agree. the 9 disc kit would be a good choice.

 

seems it the sand riders that need the bigger springs

 

Talking strictly bolt-on modes I would think rider wieght would really come into play here as well. Lighter riders under 190lbs could probably get away with 40% or alternating 60% with stock. Whereas some of the heavier guys may require 60% all the way around.

I'm getting ready to change my springs but don't really want the pull of the 60%. I have felt them on other bikes and don't care for the pull. I weight 185lbs and think I would be fine with the 40%.

 

I use the Barnett 9 disk system, with the Barnett springs. Thier springs are not much stiffer than stock. I havent had my clutch slip since.

That is good to hear. I have heard of others not having much luck with the Barnett setup. The carbon fiber disks end up slipping and fragmenting into the oil supply. Not good! Maybe they aren't installing correctly or are using the wrong type of oil.

 

I use Valvoline VR1 50w

I believe the people that are loosing thier Fibers are the one using the 60% stiffer springs also. IMO.




bigger.

 

Mine started slipping at less than 10hrs of ride time. Just as soon as I did the mrhp46, the end cap and ported intake the clutches started slipping. I went with the 60%, the pull doesnt bother me, but wish I had gone ahead and gotten the barnett setup like a couple of people on here told me I should. When I have everything apart I will do the barnett.
