Default At what HP/TQ do you need to start worrying about your clutch or clutch spring?

I am at 112HP and 116TQ on my Hammer. I have some slight concerns. Running stock vic oil.

KMC/Lloydz Tune
TorqueT
CC Octanes Exhaust
PCV + Extra 500RPM
Cams
1/4 Turn Throttle
Timing Wheel
ECU Unlock + 500RPM plus speed governer removed. Goes to 152 mph.

Is there any upgrade I can do right now so that I do not have issues later?

Thanks guys.

Is your clutch slipping? I am at 110/110 on my CC with about 10,000 on the mods and have not noticed any clutch issues so far.

I am not sure. I have never experience clutch slip on a bike so I am not sure what it really feels like. I don't know the signs of what to look for when it starts to happen. I am just trying to be proactive.

I would not be worried about the vic oil. I am at 200HP and run vic oil. I would say 130hp you might get some slippage. I know for sure you will slip at 150. I would not be worried about it until you actually start slipping. If you want to be pro active put in a barnett Scorpion clutch. That should be good to anything you get up too. If you are going to try to get in the 180s or higher I would suggest getting someone to machine your primary and put a lockup in it. The 99lbs springs in the barnett have some issues. Maybe this winter I might do that we will see.

Why not? It's a thrill in a nutshell.
Op, I wanna think that somewhere in the 120-125ish area is where you might want to start thinking about the clutch spring and support cover upgrade. Bikes will vary, oils, rider weight, bike weight, clutch condition. Allot of variables.

I had heard somewhere that all the was required was a spring change or something? Sounds like I will be okay.

This isn't the video I was thinking of but they slap a supercharger on and don't mention anything about clutch springs.

Why do you need a car with air conditioning. My 70 Bug is perfectly adequate..........O yea never mind. My bug is big bore, ported heads, dual carbs, 120 cammed, electronically ignited......That's why


Now that that is out of the way. Below 120/120 you have little if anything to worry about. If you need more do it right, and add the Lloydz variable. The Barnett solutions radically increase pull at the lever, and will destroy cables, and slave cyls.

I'm not an asshole...I just type that way
