manual clutch springs

[Jmoozy27]

What are the pros & cons of putting heavy duty spring instead of oem? I plan on putting a 200sx quad motor in a 2nd gen 200x frame and I'm curious what would be the benefit of using them. The oem spring are within spec so I can still use them. Will heavy duty springs negatively effect performance? I will be going up a piston size and have a wiseco 10.25:1 if it makes a difference. I may use an aftermarket exhaust if I can find one. Thanks.

Clutch springs are like octane. Use only as much as is needed.

Pros:
Keeps the clutch plates lasting a little longer when the pack starts to wear
Reduces slippage at high speed, or up hill
Will hold a slight warped pack together where stock springs wouldn't
Builds strong forearms (if this is a manual clutch trike)
Keeps kids from wanting to use your trike

Cons:
Harder to ride in tight areas where slipping the clutch is required
Can be a little "grabby" when trying to slip the clutch smoothly say in a drag race launch
Clutch cable and pivot points wear faster
Hard down shifts will damage the clutch basket a little more than with stock springs
Risk of carpel tunnel syndrome

El Camexican is dead on correct.

You don't need stiff springs with that motor, put the money elsewhere.

Roger that fellas, thanks for the quick info

So..... A racing motor or a racing machine would be an excellent candidate for the heavy duty springs?

I have a heavy duty kit from Barnett and haven't installed it yet into a stock 86 200x with dg pipe and jetting + k&n filter. Always was led to believe they were better seeing ads and reading magazines years ago. Maybe just for racing.
If I put it on is my girlfriend gonna be able to work the clutch? Shes average, dainty, weak, complains alot.
I love her. Buy regular springs for the Barnett kit?

I read the whole thread including post #2, El Camexican or anyone could you please comment on this spring topic for a close to stock Kxt 250 ? Kxt would be considered a racing machine.

Yep, better mileage, more horsepower, longer piston life and better tire wear. Also cures hemorrhoids. I've seen that ad too!

Geez, easy on the complements there lover boy! If it's that bad this may be an area you want to upgrade in. If not, get her the stock springs

MX, or drag racing? If the plates are all in good condition and the springs are within spec I'd leave it for MX. If you plan to drag it or climb hills I'd try the HD springs. I belive it was onformula1 that once suggested mixing stock with HD springs (half and half spaced equally) you might want to try that. If you are concerned with opening your clutch cover repeatedly to experiment just take a new gasket and very lightly coat both sides with a smooth layer of automotive silicone and let it dry while hanging. If you do it right you will be able to reuse it multiple times.

As far as a motor with a semi auto clutch would there be any need to run HD springs?

Very tiresome on the foot on an auto clutch with HD springs .
A performance motor would benefit or if heavy pulling is done yes but for general use not needed .

That was me, you can mix stock & heavy duty springs and come up with a "Medium duty" spring set.

ONLY do this if you have a even number of springs in your clutch set up. 4-6-8 evenly space them out.

Don't try this on a odd set up like a 5 spring clutch.

I know people that do it and say it works fine, but bench testing by pulling the clutch lever in & out why looking at the clutch assemble and you will see it off kilter. Don't risk the extra wear.

When I was a little kid I thought everything in a magazine was better than stock...Later is life I now only fix a problem when there is a problem.
