1985 350x clutch frictions - ebc

[Micahdogg]

A friend of mine needs a clutch overhaul on his 350x. It recently started slipping a little in the higher gears. I want to use EBC frictions and reuse the stock steel plates. Can anyone confirm that CK1190 is the right part number? It looks like an array of Hondas used this same clutch kit (NX250, XR250, XR350, TRX250X, and even the 81-84 CR125). The prices on these kits are all different though so I would rather buy the cheapest one. Thanks.

I wouldn't do that if you gave me those parts; Thats a bandaid on an amputated arm....

X2 on that. Just buy a kit.

Kit is best.

I never used the EBC clutches, but I have had good luck with their brakes. As far as part numbers, from memory, the 250es big reds use the same clutch basket/fibers/plates. I don't really get the above comments, if the plates and basket are in good shape, what is the problem reusing them? If they fail, you no longer can get power to the wheels, seems the machines with no brakes would be a larger concern. Maybe I'm overlooking something?

I've used EBC clutches in 3 personal machines and have not had any issues, or premature failure to date.

The reason why I personally prefer a complete kit (frictions, discs, and springs), is for the simple fact that they are all new components. Stiffer springs for better clamping force, especially on the performance builds. Flat, non-glazed steel discs (some claim better oil retention, some are actually thicker then stock giving a higher stack height).

Many prefer stock clutches with the addition of stiffer springs.

I must have skimmed over your reply, my reference with the posts above was about the personal injury caused from replacing only the clutch fibers. I do agree replacing everything is best, but sometimes money is tight.

Thanks for the review though, my 86 350x might need a clutch soon, and I was looking at replacing them with either EBC fibers, or a whole basket from a 250es/250x since I have a few spare used ones.

You guys have a ball with inexpensive parts. I like to open the clutch cover once, and not touch it for another 10 years. Barnett and OEM are all I'll install.

To each their own......

Get the Barrnett dirt digger kit

X2 on the dirt digger. better quality and take more abuse.

[yaegerb]

Barnett or OEM is the only way to go. I have seen EBC clutches fail multiple times.

[DohcBikes]

Use whatever you want. I have seen OEM, Barnett, and EBC clutches fail multiple times.

I'm going on 6 years with one EBC clutch in my Fourtrax. That is the oldest clutch I have in any of my machines at the moment. I do have a brand new Barnett Dirt Digger kit in my tool box for the Fourtrax because I got a hell of a deal on it. Biggest thing is frequent oil changes, proper cable adjustment, and not abusing the clutch. But, that goes for any clutch.

Just be assured it comes with the steel plates as well. I have bought some aftermarket clutch kits and some have the steel plates, some not. The 2 kits I got last were "White Bro's" made by Barnett; But, I don't think they came with the steels. Most of these kits do give you the 4 new springs though.

Then get a new clutch cable or silicone smooth that cable for a nice clutch operation. A soft strong clutch is sooooo nice!!

NEVER open up a motor to "re-use" parts that wear. It's just not a smart thing to do and you'll learn the hard way.

Thanks for the replies guys. There was a time when i replaced parts for the peace of mind. But now i take a more economic approach to things. I'll mic the steels and if they are in spec and not warped, i will rough them up. This is a stock trike that hasnt been abused so it just needs a functional clutch again.

I purchased a 350x with a new clutch.Wasn't long and the clutch was slipping.Tore it appart to find new fiber plates.Had used metal plates.You easily tell they weren't as new..Measured both and they were good.Clutch was adjusted properly also.I purchased a whole new clutch kit.Didn't know what fibers had been installed.Everything worked fine.Strongly suggest the whole new kit.The clutch will work so much smoother also.For the little extra money,good insurance.Look what a gasket will cost,times two.You hunt around some and clutch kits can be very reasonably priced.

[Dirtcrasher]

The hardest spec to get is the "warped" dimension. You need a piece of flat glass on a good table and use a nice set of feeler gauges all the way around...

Just to update, EBC # CK1190 is the right part for 350X clutch frictions no matter what the box says. This kit was for a NX250, but it was $35.00 shipped which is why I got it. Spent a half hour carving out a new clutch side gasket from a roll of Fel-pro stock for $6.50. Clutch is as good as new!

The old frictions were actually in good shape and within spec, but the steels were glazed. The clutch springs were also sacked out by 1 full mm. We roughed the steels up with 220 grit and installed the spring shims, but all I ended up doing was shimming the clutch stack 1 mm :) Now that I know what I did wrong we can make some new shims, but for now it is all assembled with the springs as is and it works great!

Thanks for the help guys.
