Clutch problem?

Hi,

This week i had a strange problem for the first time but it suddenly disappeared.

Sometime when i drive at night i like pushing the throttle all the way getting on the highway, I climbed to 80 km\h (about 50 miles\h) at about 35% throttle and then i twisted the throttle to about 80%-90%, the RPM went all the way to the red line (about 8000 rpm) and i was only driving 100 km\h (about 63 miles\h).
For the rest of the trip whenever I pushed over 50% there was a feeling that something is slipping without any real acceleration and the RPM went all the way.


The next morning i tried to see if the problem is still there but nothing, everything is running ok.

Two weeks ago I changed the Drive train belt to a new one (Gates), I have Dr. Pulley 24gr sliders for about 6 month (6000 miles), 2006 Silver wing with 63,000 km ( 40,000 miles) on it.

I first installed my 24 gram Dr pulley back ward's and my rpm and acceleration went really high.I went on u tube and saw a video by Big Bird and reposition the sliders. The other thing that can happen is the variator nut loosen up .I would look there first for what is happening,check for oil on the variator.

What!! you changed the belt and didn't use a Honda belt? I'd say that's the problem.

The OEM Honda belt is specifically designed for the variator faces as well as the correct length. And when the belt wears it causes problems like slipping, etc. Even then it is difficult to discern the worn belt from a new one. And that wear may only be 1mm or 2mm difference.

I can't imagine Gates manufacturing a belt that could accurate substitute for the correct Honda belt. Maybe that Gates belt would work in an emergency, but it would be a bodge job at best.

The correct Honda belt isn't cheap, but suck it up and buy the right one. Then your 24gm sliders will show you the performance you're looking for.

All that said, perhaps you could share the Gates Belt part number with us. There may be others here who could benefit from that information.

The Gates belt I have as a spare (bought in UK) says 9802-41804.

That Gates part number is specific only to the Honda Silver Wing 600. I would think Gates is perfectly capable of producing a belt to the exact Honda specifications, so your slippage problem is likely related to one of the other suggestions, although it is possible (likely?) that the slippage you have experienced already has damaged your Gates belt.

Same here 9802-41804, I bought the belt at Wemoto

I guess i have a job for tomorrow .

When I think about it it's not likely that it's coming from the belt because the V-Belt indicator didn't turn on and I know for a fact that it's working because four weeks ago the V-Belt indicator turned on and that was the reason (and km's) I changed the belt.

It does not look like the Gates belt is available in the US.

Hi,
Today I finally go the time to service my Silver wing, my intention was to check the Sliders, Bolts and clutch bell and if there was any oil in the variator.
The bolt was secured tightly, the sliders was in place no oil was in the variator but when i took apart the rear pulley and clutch i discovered the problem...
In the pictures you can see all the dust collected in the clutch bell but this was only 1/3 of what was in there...most of it fell off when i took the clutch out.

So, i think that the clutch didn't grip when i pushed the throttle because of all the dust.

I believe that is dust from the belt making its way in there, how many miles has it done since it was last cleaned out. You may be close to needing a new belt.

That is clutch pad 'dust'. However your clutch pads look to be in good condition. I would blow everything out with compressed air and then use some coarse sand paper to roughen up the pads.

Unless you are riding in a lot of stop & go traffic you might want to consider switching to Malossi clutch springs (white). The Malossi clutch springs are 'stronger' and will allow the Silverwing to rev slightly higher (closer to the power band) before the clutch engages. They won't, however, allow your clutch to grip any tighter the way a Dr Pulley HiT Clutch will.

And, oh yeah, be sure to grease that internal needle bearing in the clutch outer.

I bought the Silver wing 2nd hand and drove it 20,000km.
When i drive to work in the morning i do drive a lot in a stop-go traffic so i guess that the main reason for the wear of the belt.
I never cleaned the clutch bell and I replaced the belt few weeks ago.

And i did greased the bearings before i closed everything.

Thanks everyone for your help
