• Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

630 Hydraulic Clutch & Plates

So my clutch master cylinder started leaking. Need to take it apart and inspect but I'm pretty confident its coming from around the piston. Lifted the silicone shield and it was pretty wet, then as I started making my way home it started oozing out on the lever and the clutch started feeling funny.

Going to get a rebuild kit for it and from what I understand should fix everything. Thought I'd bleed the brakes and all that fun stuff while I was at it.

What about the clutch plates? I know they last for quite a while on the sportbikes, how do they typically hold up on a supermoto? Lots of clutch ups and really heavy down shifting seems like it would eat up clutch plates pretty quick.

I was thinking about messing with the clutch plates and getting some stiffer springs and would like some feedback if anyone has some experience with it it.

Bikes only got 2000'ish miles on it so I'm sure they're more than okay, just figured while I'm there might as well put some fresh plates in too...

Thoughts?
 
Mine master cylinder is leaking as well. I think Hall's is going to send me a whole new master cylinder under warranty. As far as the clutch plates go, I have no idea. I'm at just over 4000 miles on mine and everything works fine. So, I'm leaving it alone.
 
I spoke with my dealer today and they're going to warranty the rebuild kit for me which rocks! But it wasn't without a couple jabs from my buddies who have cabled clutches and took the opportunity to point out that hydraulic sucks and cabled rule. Then I reminded them about that one time 140 miles from home when their cable broke they didn't have a clutch at all and that mine was still working

How do you like the clutch on the 630 temple? Have you had hydraulic clutches before? This is my first and am still on the fence if I actually like it or not... I like the feedback you get from a cable, hydraulics dampen that a lot but its not completely gone. I notice some slipping when I'm leaving 2nd and hammering 3rd. Nothing thats abnormal I just don't like it. Hence my thoughts about heavier springs and new plates while I'm there.
 
When my TE510 hydro clutch leaked a bit after a few thousand miles and I was told that when the clutch plates wear it increases the fluid in the line and reservoir. I simply opened up the reservoir and it overflowed due to too much fluid. Ensured that the correct amount was in the reservoir and it hasn't leaked in 6000 miles.

Thats some good info there. Makes perfect sense too. I like it :thumbsup:

I'll go pull the cap off of mine and see whats going on in there.

I really like the smooth action of the hydro clutch. This is my first one. I haven't had any slippage issues that I've noticed.

You know, mine was leaking around the cover gasket late last year. When I pulled the cover, the reservoir was completely filled to the rim with fluid. This was with about 3000 miles on the odometer. I took some fluid out and replaced the gasket, and the leak stopped. Now that you mention this, I'm wondering if my reservoir is too full again. I didn't remove much fluid at all, just enough that the level was down below the lowest point on the gasket.
 
Holy Crap am I glad I took the whole clutch assembly in. The dealer went to put the rebuild kit in and said that the clutch shouldn't have lasted 500 miles. So because they absolutely rock they swapped me a whole new one off of a new bike. Got home and started putting my bike back together and noticed a small crack in the new one they just gave me :eek:

It doesn't seem to be leaking but I think I have some bigger issues with the mineral oil I used. Apparently if the bottle says on the front in big bold letters "Mineral Oil" its not necessarily 100% pure mineral oil... Turned the bottle over after the fact and it said Active Ingredient - 99.9% Mineral Oil and Intended Use - Lubricant Laxative... I think I just fed my clutch laxatives. At first I was :eek: and now I'm :lol:!!! Nice one nard LOL
 
+1 That makes perfect sense to me, plates ware down and push the fluid back up and its gotta go somewhere right? If you pull the cap off though and the fluid is a funky color (should be a red'ish kinda color) or looks like old motor oil like mine did I'd take it in to the dealer for a new clutch.

So far two out of two of my OEM Magura clutches have been faulty. Starting to think about dropping some coin on a new better quality billet clutch master cylinder and maybe even upgrade the brake too.
 
I took some fluid out of my reservoir and removed the lever and cleaned up the seepage. The fluid level was too high, but it wasn't up to the rim of the reservoir like it was last fall. I used a syringe and lowered the fluid level down to where it should be.

The fluid looked clean.

I haven't heard from Hall's yet on a replacement master cylinder. I just sent them another email for an update.
