Anybody notice clutch slipage.
« on: January 01, 2010, 10:05:53 AM »
As the power output of the engine starts to climb. Im noticing some clutch slippage.

Is anybody else notice this.
It only seems to happen on some days. I.e. when its cold.
Once the bike gets up to operating temps. It seems to be less.

The new UCE engine seems to have a much better and beefed up clutch.
So Im wondering if Im imagining it or its an issue that is there.

I normally like to run EBC plates. Does anybody have a number for EBC plates we can run on the bullet.
First step I guess should be to shim the springs, next step stiffer springs,
But if I could get some EBC plates Id feel much better.

Also the clutch seems to engage only just before the lever is fully released.
Also to disengage the clutch it seems you only need to lightlly touch the level.
Ive adjusted the nut on the clutch cover so now I have 2mm off free plat.
Is there any other way to adjust how the clutch kicks in and out ?
Like on the RZ if you take off the cover there is an adjuster screw.
Really need to get a service manual.

I must admit that I'm unfamilar with efi bikes, a couple of times going into third around town  at 50kph, I've given it a bit of throttle and experienced what I perceived to be a bit of clutch slipage but after a while I now think it is only a natural thing in my not being used to the accelaration takeup from that speed in that gear with the efi. The bike certainly shows no symptoms normally associated with slipage.

Sorry can't help.

Cheers

I would think that making clutch slip a thing of the past, combined with light operation force, would have been important design goals for the UCE. It shouldn't be behaving like a Classic with filter/muffler upgrades and standard clutch springs.

I remember gazing in wonderment at the clutch on my new Honda 250 in 1980. The basket was the same size as my Triumph 650 and the lift mechanism bore against a caged ball bearing! I could pull that clutch in with one finger and it never dragged or slipped, no matter what heavy use I inflicted upon it.

I remember thinking, "so it didn't take rocket science to make a clutch work after all."

I'm at 3,500 miles on my G5, but haven't noticed any clutch slippage. It's colder here now, but I went for a ride today (low 50's F) - bike ran  smoothly.

No clutch slipping om my C5!
On the eighth day God created the C5, and it was better looking than anything on the planet.

I have 4200 miles on my G5 and it runs smoothly.  The transmission and engine runs better in colder weather.  I like its clutch, it is lighter and better than older Bullets.  Only minor adjustment of the clutch cable is done if needed.

thanks guys.
It could also be a sticking cable. The routing is a bit stiff.
Will oil the cable and route it properly.
Hope this cures it.

cable serviced.
The first thing any UCE owner is going to run into as the power output climbs is going to be clutch slippage.

EBC CLutch plates and custom Clutch springs will help to some extent.
But a lock up may be the only route if you cross 35 BHP.

Ron,

Are you making uprated custom clutch springs for the UCE?

Cheers,

Jay

May be
first I need to see if the existing springs we make and use on the RDs can be used on the Bullet.
The UCE basket looks identical to the RD basket.
So Im hoping the EBC plates and springs will work.

If there is a ready solution out there why not try that first.
Ive not reached the clutch side yet.
Still stuck on the Cam side

The EBC plates work well on the older bullets. Many people are running EBC plates on the older bullets. Not sure about the UCE though.

Cheers,

Jay
