  • 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 The previous version was outdated and no longer supported.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!

Hi all, i havent had my 07 450 for long. But whats happening is shes stumbling at 1/4 throttle and then some times bogs down. i'm also getting loads of decel popping which is annoying. Ive repacked the muffler and sealed the exhaust joints checked both sides of the manifolds and everythings good. The only other thing ive done is remove the evap pipe from the manifold which ive also sealed up. Any ideas on how to sort this out. The second question i have is my clutch is grabby so im expecting to replace the clutch friction plates does anyone know what year crf friction plates will fit.
 
I am using 2008 or 09 crf clutch plates from EBC, they have outlasted the OEM plates.

I'd say your jets, especially your low speed/idle/pilot jet needs cleaning or replacing. varnish can build up in that smallest of jets and really affect the bike's running at idle and decel.
 
Here's my write-up on clutch plates:

A few months ago, I'd get this grabby, snatching feel from my clutch on cold take-offs, never really had it happen at full temp running. I DO abuse the clutch alot on tight sections, since I am geared so high, I have taught my left hand to be my Rekluse, this bike never dies, but the plates takes alot of abuse as I slip and feather the clutch. New Husky frictions are packaged as a set with the steels, for about $150. I got some Honda CRF450 plates for about $60 delivered, below are the specs.

EBC friction plates, part # CK1247
Width of tab = .540 - .542 in.
Distance between tabs = .915 in. (approx)
Thickness of plate = .114 in.
Diameter of plate = 5.4 in.


The plates fit into the hub but so far, the measurements are disappointing, the .114 thickness is the wear limit for the 450-510, new Husky plates are supposed to be .118 thick.

Wow, just took a test ride and the time when I usually get the grinding/snatching/jerking action is GONE, it's all butter-smooth now, on cold take-offs in a high first gear with plenty of clutch slipping. The new EBC plates reduced my tab gap (Clutch housing to friction disc clearance) from .8mm to .6mm, the limit for wear. The .6 gap is probably the smallest I'll get it to, with all the wear on the clutch basket slots, but the .8mm gap that I did have was what I thought was giving me the snatching action on colds take-offs. Here's a pic of the plates for comparison, the EBC plates have the steel plates stacked in them, the Husky plates are on the right, the EBC plates seem to have more cork surface area than the OEM plates. I can tell there is no slipping going on, the new plates are hooking up real good.

Thank you OHR, ill get the plates ordered in the morning and then get the carb off for a good cleaning.
 
Just a quick update on the clutch CK 1247. The friction plates dont fit the centre diameter is to small and the plates dont fit into the clutch basket. (On a side note at least i have new plates for the wr 250) Does anyone have any more ideas on which after market plates will fit a 07 TE 450. I sure ive found what was causing the ruff running the o ring and spring was missing from the fuel screw and the fuel screw was turned a quarter of a turn out.
 
well quick update, im still on the hunt for a clutch pack, but after fitting a new brass fuel screw my te 450 now idles and no stumble or bog and idles great.
