Lockup Clutch?


dajogejr

Recommended Posts

I'm building a 4 mil cub in the next month or so.

 

I'm looking at the direct drive lockup clutches.

I play drag with my buddies most of the time, but...still want to be able to run some trails. NOT Tight, whooped out trails...but, fire road style...

 

What are the cons of having a lockup style clutch?

I already know the clutch bascially can't or won't slip, it will last longer...and I don't have to run as tough of springs...but, what are the demons?

 

Thanks...

 

:cheers:

All clutches engage.It's just that once you really start making big horsepower or the clutches get worn they can't handle it and start slipping.The lock-up just helps them not to slip.No sence putting alot of money into a motor and lose it through the clutch.

I would say the only cons is the price and the extended case might get in the way.

It's only 120 from direct drive. Nothing, compared to the thousands you can dump in a motor...

 

How much extra does the side case stick out...you got a pic by chance?

 

the pics on their sites don't do it justice...I don't think...

 

They show one on, but without the side case modded.

It adds about a 1 1/4" to the side of your clutch cover. You won't notice it. In my opinion it is money well spent. If you are running the lock up you can still run your stock springs then you don't have the heavy pull of the stiff clutch springs alot of people run and your clutch is going to last along time.

Well thats what i was guessing, but a clutch is still a clutch. All clutches are made to LOCK UP. So it I wouldnt call it a lockup clutch is just a hi performance clutch!

Sorry I had to be a smert AZZ!  :yank:

its not a clutch at all, but rather a clutch lockup.works with centrifical force and the more the motor revs ,the more pressure it applies to the clutch pressure plate.its a great investment for higher hp and torque motors exspecially if your drag racing.i have noticed that in time it will put wear marks on the pressure plate where the fingers apply pressure.if you do go with a clutch lockup,be sure to also install a bearing kit also to prevent the clutch adjuster,ball and pushrod from melting themselves together and possibly even melting pushrod to the inside of tranny shaft.the bearing kit only costs 40-50 bucks and is a great investment even if you run a totally stock banshee.

It's going to require you to put spacers on your right foot peg to clear the extended cover. This also means longer bolts on the peg. I also had to tweak the brake pedal to work well with the wider cover.

 

I've never ran a lockup except on engines with an override transmision. If you are still manually shifting with the stock transmission, the lockup may make shifting a little harder. Seems to me the lever would become much harder to pull when the lockup is engaged. Something to consider.

 

I've also heard a stock clutch setup using an aftermarket HD clutch pack can handle 70-75HP before slipping becomes an issue.

Does anyone have picture or a diagram of what the pancake bearing replaces? I am loading putting together a new motor and I swear this new bearing set up I have does not look like the old one I have in the bike. :confused:

The only con I can think of is more rotational mass that your engine has to overcome. If your clutches slip, then obviously it is a benefit. If your clutches aren't slipping without it, then it's a disadvantage. There's a price for peace of mind knowing your clutches won't slip, cause if they do, it may cost you a race. If your running high HP and you can't take the risk of a slipping clutch, then it would be a must.
