How do stiffer clutch springs help? What is their advantage....? How to do it? And its pros and cons..... I dont know how it works. I only heard that it increses torque. I want to do it on my bike. Plz advice me

Not a single reply...... i m waiting for joel's reply if he comes accross this thread. I know he is the perfect person to answer this....

Stiffer clutch springs help in more efficient torque transmission from the engine to the gearbox. The torque transmitted by any clutch system is a direct function of the axial force at the friction material. The stiffer springs help in increasing this axial force and hence the better torque transmission.

Note:The use of stiffer springs will increase the efficiency of the transmission system. Torque produced by the engine however will remain the same.

okay maybe i gott your point..... That means if i use stiffer springs the torque produced from the engine will be used in a more effective way right? That means low end grunt will be better? Will the engine pull more effectively? And wht are the pros and cons? I dont know anything about this thing

Reduced transmission loss, for example if your engine produces 20 bhp at the crank and 18 bhp at the rear wheel, the clutch springs will reduce the transmission loss resulting in more power being transfered to the rear wheel where it is needed, they also improve shifting giving more precision.

Yes. You got my point. Low end grunt will be better if your current springs are not producing enough axial force. But the use of stiffer springs will make the clutch lever harder, means more effort for pulling the clutch lever. However this may not be so much that your hand will hurt. But can't say for sure.

Achcha now i got it.... Thank you both.... Will that decrease mileage by any chance....? And what other negative impact? My bike is tvs flame..... Its has got a real raw low end grunt bt i just want to try the experiment..... what about clutch plate life and mileage? And any adverse side effect on my bike....?

^^ Clutch plate life would depend on how u shift gears, and if you rev and then release the clutch ( sudden dump etc ). But ideally clutch life should improve, since there will be less scope for slippage.

Just as a caution, since its a smaller bike, make sure that the clutch cable can take the additional stress. Else you will be stranded with a broken clutch cable.

Indeed a very valuable point. I missed out on it. The cable has to be strong enough to pull the clutch back and yet not break.
