Clutch Lever Pull Pressure

How many people are running heavy duty clutch springs in their bike? Aside from the added force to pull the lever in is there any problems with running them like hard to get the bike into neutral? The reason I'm asking is that I made a up a couple of prototype pieces that will decrease lever pressure. Right now I'm using stock springs and the lever pressure is easily half what it was. Is there anyone interested in this modification for thier bike? Mike J
 
Show us what you have. I would think that to cut the pull force you need to increase travel. Or make some kind of an assist.

With the drag bikes, there is no clutch cable on the sliders and I for one do not use all the springs on any lock-up I have setup.
 
Lecroy, it's two pieces CNC machined that move the clutch cable and the pivot point of the arm. Sorry I don't own a digital camera or I would send some pics. This would be nice for those with stiff springs or someone who just wants an easy clutch. Mike J
 
Ok, not sure if I am following you, but if the plan was just to increase the arm length, why not just make a new arm, or weld in a section??
 
If you made a new arm you have to be able to cut splines and I don't have that capability. I'm not a big fan of just welding something on either. I know lots of people do it but with my parts they can be removed and the bike put back to original. Mike J
 
I have heavy duty springs, billet basket. Getting stuck in traffic will wear you out, but taching it up and letting off the clutch it is really nice to get the power to the rear wheel even if it becomes a puff of stinky smoke before getting to the groung.
Send me some photos whenever you get them, I would be interested to see what you did.
 
Do you notice any bad side effects for the heavy springs? I want to keep the bike 100% streetable and to me heavy springs are not an option with the heavy pressure to pull in the clutch. I took a ride this evening, man you can pull in the clutch with one finger!! Mike J
 
I had Heavy Duty springs in my 1100 years ago and It was hard to get into neutral and missed shifts were common. My then local Suzi dealer said that Stock springs work best so I put in a new set and everything was juuuust fine.
 
I have a bad left hand and run all hd springs in my gs1100. I always put the bike in neutral before i stop. I really cant see whaT THE DOWN SIDE OF THEM WOULD BE.
iF THE PRESSURE IS NOT COMFORTABLE, REMOVE SOME HD SPRINGS BUT DO IT IN PAIRS THAT ARE OPOSITE ONE ANOTHER.


sorry for the caps

Another thing would be to install the HD springs 2 at a time and see where you get to dislike the setup.
 
I know that on some bike the springs are so stiff that they cause the pressure plate to flex and can cause the bike to be very hard to get in to neutral sitting still. I can cure the stiff clutch lever with the pieces I have made but if the pressure plate flexes then my parts won't help that. Mike J

will it have any effect on cable longevity ? kind of tired of heavy springs but maybe its easier then having to replace springs .Robu

Many people have the idea killer giga-tension stiff clutch springs increase performance. This is far from reality. 99% of us have a STREET bike. There is absolutely zero advantages to race springs on a street bike. "Racing" applications, well thats a different story. I have heard TONS of horror stories about guys swapping out to super stiff race clutch springs to gain performance, only to comment a month later that now they have arthritis in thier left hand from being stuck in traffic with stiff clutch springs. Myself (and many others) upgrade using Barnett fiber drive clutch plates, and run the stock Suzuki GS springs with awesome results, and still maintaining perfect driveability.
 
What is normal lever pull for the clutch? Mine on my 78 GS1000 is very hard. I don't run into a lot of heavy traffic so it's not a big deal, but I'd rather it worked normally. So what is normal?

Mine are really hard to pull so it would be a blessing, the bike was that way when I bought it. Would love to know more. Thanks.

Check your clutch cable for free movement. Mine was partially siezed, resulting in excessively hard clutch pull action.
