On the end of your silencer theres a protrusion....Youre gonna have to get that protrusion lengthened by welding a nipple on it to lengthen it then clamp the hose on route it back around and down towards the rim sprockets..Id use about 16-18" piece of 5/8" inside diameter silicone rubber high heat hose......Did something similar to my mini trike of death because of a similar reason aswell as the noise it made....It is quite loud.......

Still loud after the mod?

By the way, won't it make it look ugly? Lol.

Re: Motor bicycle build. Reduction tranny on cag engine.

So I measured the small hole that sticks out of the silencer. It measured to be sticking out almost 1/2" and the outside diameter was 0.635" which is just a little larger than 5/8" (0.625").

So do you think I need to lengthen the protrusion still or is it large enough? (I don't have a welder).

Also will this block exhaust flow, thus sacrificing performance or is it only minimal?

Will this tubing work? I think firm is better to choose than soft. I hope it's the kind that doesn't melt and preferably black in color:

If you dont have a welder you can cut the small protrusion off and tap the end cap for a 5/8"od brass barb...

That black temp resistant hose will work and the perf loss will be minimal but the quietness will maximize.....

Re: Motor bicycle build. Reduction tranny on cag engine.

Approximately how long of an extension would I need? I hope I can obtain that cylindrical "barb" for a local Low's or Home Depot.
Is the material thickness of the end cap thick enough to hold a thread like that without it loosening up?

Also do you have a picture of your trike with the hose? I'd like to see how ugly it looks.

The endcap is thick enough...I used a thin ring nut on the inside from an ignition switch to keep it tight and secure....Right now I dont have any current pics of the Mini trike of death with the hose..the trikes in the storage bin because its not ridden as much.......Its not that ugly with the hose but it definately had a good effect for me...

Re: Motor bicycle build. Reduction tranny on cag engine.

I didn't fully understand the second sentence.... You use a thin ring nut on the inside of what?

So I found this:
http://www.ebay.com/itm/Brass-41-64-...item4167e08417

Will that work?
I couldn't find a smaller threaded one than 41/64" with the proper barb diameter of 5/8", and don't have a tap as large as 41/64" so that might be a problem.

Have you found anything good that I can buy?

Re: Motor bicycle build. Reduction tranny on cag engine.

In the link I posted from McMaster, the wall is only 1/8". I hope that is large enough.

As far as the barb goes, I have yet to figure out which one I can get that I certainly know I will be able to screw it.
It seems to me as if you have never done the tapping to screw the barb in, but only used some rings nuts I suppose.

Re: Motor bicycle build. Reduction tranny on cag engine.

Something is weird about my steel clutch. When I put on new springs, they don't need any stretching whatsoever to get put on so I can literally do it by hand.
On my aluminum clutch I need to stretch the springs with pliers to get them on.

So I guess it engaged early because of that. Although I will give it a shot now that I have drilled 2 holes per shoe so it should lighten it a bit. I will see if it still engages and if it does then I suppose it's POS and I'd like to buy 1 steel clutch from Cam2 for as low as you can possibly give it to me please because all steel clutches on ebay cost more than aluminum clutches.

Re: Motor bicycle build. Reduction tranny on cag engine.

The springs should be real tight like your other clutch, if there loose and you can move the clutch shoe, that's not good. They will not work right cause the shoe wil want to drag on the bell all the time. Loss of horsepower and alot heat.

Take a needle nose pliers and make the springs tighter..Thats what I did when I modded an aluminum clutch and made it over 1.5mm's less in diameter to increase stall speed......

Re: Motor bicycle build. Reduction tranny on cag engine.

That's what I did to one of the loosest springs. I'll see how it performs tomorrow. I'm still waiting on the 1 foot tubing I ordered from McMaster, and I will try to fit it on without a barb. I can certainly file the exhaust tip to the shape of a barb.

Re: Motor bicycle build. Reduction tranny on cag engine.

I was hunting for the best deal I can get with shipping included and this seems like the best deal:

http://www.ebay.com/itm/5-8-Verociou...93c9d3&vxp=mtr

However, it says to NOT use with fuel and oil. Hmm, will it still work for exhaust? Which one do you use?

I'm pretty sure the link I posted to McMaster don't support fuel and oil either, and I didn't want it either because the hose itself cost more than this hose with shipping combined.

Re: Motor bicycle build. Reduction tranny on cag engine.

Or I can just try this:

http://www.ebay.com/itm/10-AN-Push-L...ed551e&vxp=mtr

300F should be adequate.
I haven't seen any silicone hose that can withstand fuel.

So do you guys think I should go with that or do you have another suggestion?

Re: Motor bicycle build. Reduction tranny on cag engine.

I measured and approximated that in order for the hose to reach the chain, I will need about 2.5-3 feet of it. And I don't know how good or bad that would look and I certainly don't know if that's bad for the engine and/or its performance.

I bent my muffler so it points down and guess what.. I can't believe that solved the majority of the spitting problem! It may spit a little, but it doesn't seem to spit as bad as it used to.

AND, my exhaust sounds more like a car with big mufflers and less like a weed wacker so that's a good thing. However at very high RPMs it is loud so doing that tube mod might be necessary to eliminate this.

Here is how the muffler looks you can also see that cover I put around the exhaust and made it hold it place via exhaust strap ball held ties:



I managed to FINALLY put on the steel clutch after bending the springs to an unacceptable level that I somewhat damaged them, so I'm worried they might snap (even though I rode about 10 miles today with no problems). I think it's the steel clutch that caused me to keep making them tighter and man the springs were so HARD to put on. I bent them a level smaller and smaller over 5 times until I got it right where I wanted it. It just kept engaging and then FINALLY it worked.

Man I think I need a new steel clutch. CAM2 can I buy one from you for cheaper than I can get one on ebay please?

Aside from that, while the steel clutch doesn't engage at IDLE, but engages right away when I give throttle, the engine revvs up slowly and I feel like the clutch pads do not rub too hard or anything. And this allows for a much smoother acceleration and ride in a way.

It accelerates slower than before, but it's not a big problem because I'd rather have long lasting pads and a smooth ride than a quick engine. Oh and it might save me some gas due to slower revvs lol.
Decelerating however, might be somewhat problematic in the long run because the clutch has problems disengaging, but I hope it will last.

I took it out yesterday and no oil was trapped in there.
