Silicone friction pucks? Now there's a interesting idea....

The SBP hose material is what I'm using now, but it's on the thin side. Fine for a temp fix. What I'm getting is a 10' length of 1/2" round solid silicone so I can get it thick enough to clear the clutch ring.

It's got grip and held up on a 20 minute ride in 90+ temps. Squeaks a bit when pedaling with the clutch in though - but that's going to be fine tuning in height.

Re: what did you do to your motor bike today?

I let a friend ride it so I could hear how loud/ quiet it is now after making the crossover exhaust and modding an air compressor's air filter to fit. I wanted to hear it from a spectator's point of view as the bike went by.
He crashed. The bike slid out from underneath him as he was taking a corner that had a bit of sand in the road. I must say that he did a great job trying to save the bike. Both his knees took a beating though. He was wearing cut off pants and got some good raspberries on both knees. I could care less about the bike, I was concerned about him. He could care less about his bloody knees, he was apologetic and worried about the bike. My wife nursed his knees while I drained the fuel tank which was leaking pretty fast. I thanked him for trying to save the bike, but told him to save himself next time, no matter what he was riding.

The muffler got a teeny patch of scratches, the right grip got a bit of road rash, and the petcock got spun around (how on earth that happened, I don't know) and stripped the threads off of it.

I found out that a spare original Hodaka Ace100 valve that I had lying around was a perfect match, so on it went.
I'll re-install the tank tomorrow.

Re: what did you do to your motor bike today?

Just received 2 10"x10" samples of Ultra High Density Bendix Clutch material. One piece is 1/4" and the other 5/16" thick to try out as clutch pucks. This is rigid ferrous metal impregnated material that doesn't put off too much dust and should be great for the China girls clutch pucks.

The first ones I am going to cut out on my band saw to try and if they work well I will have them cut out on a water jet and make them available for other people to use.

This material is kind of expensive and to have them cut out wont be cheap either. I saw someone selling round pucks for $25 per set (vs the $6.50 OEM price per set of 15) and thought that kind of high but if the work and wear better than the originals it might not be too bad of a deal...

My question is:

If they work out would you all be interested in them and what kind of prices would you pay for quality clutch pucks?

Oh well down to the shop to get to cutting. Hopefully will have them in by tomorrow to try out.

Re: what did you do to your motor bike today?

Mark Ive never had to replace my clutch. Im still breaking in. I would deffinetly buy better quality. You should start another thread. You would probably get more responses.

Re: what did you do to your motor bike today?

Its interesting. I think a thread about it would be good. I'm just using the stock ones. I haven't worn any out because I don't slip the clutch to pull the bike on takeoff, but it is fascinating because I wonder if harder pucks will make brass shavings in the compartment. The china girls seem kind of "cheesy" to me, but they are lots of fun, so I bought another one after my first one blew up, and saved the spares. I'm having a good time with it.

I bought a used kid-trailer for mine, to use as a grocery hauler or fishing trailer. I found one that clamps to both the seat and chain stay at the same time with "ears" on the clamp halves, so I feel like it will stay put and not catch the motor chain.

John I did start a thread with a 2 question poll here in the for sale category to feel out the market:

http://motorbicycling.com/f23/ultra-high-density-clutch-pucks-31484.html#post303025

Thanks for your response I just got done measuring 3 different clutches I had laying around and each of them had slightly different puck sizes (up to .020" so much for not having to fit them). I am going to go with the larger of the puck size and a little sanding will allow people to size them to float in the carrier they have.

Re: what did you do to your motor bike today?

I ride kinda gently and have had no problems with clutch pucks but many have.

This is funny. Carol and I host a picnic/ ride thing here in the spring. First one, (and curse me, I forget who) kept taking off on his China Girl with out pedaling. After we asked him about how to, he was showing us and some one said "ya, but your gonna burn out your clutch"

With out skipping a beat he said; "ya, but is a 10,000 mile clutch and a 5,000 mile engine. I'm OK with that"

I literally bent over laughing. (you guys are some of my favorite lunatics)

Re: what did you do to your motor bike today?

This thread and the Snork thread go together. I do wonder about how long the beer cans hold up though. I wonder if anybody has 10,000mi on one, or if everybody just has a box full of parts and hopefully 1 running engine.

Re: what did you do to your motor bike today?

Question should be - What did your motor bike do to you today? Driving home from work today (about a 10 mile ride one way) and my muffler cap decided to come off. Rode the rest of the way with a straight pipe muffler. Man does the power increase on them china girls when the back pressure is cut down.

Re: what did you do to your motor bike today?

Lol Happy! I wasn't raptured either, so I guess we're all sinners, of the 2/4-stroke... :p

Cowboy, these engines don't like not having any back-pressure, they tend to over-rev and disintegrate stuff... like bearings.

My father always told me, "An engine will always run better just before it dies" take heed, brother.
