I'd left my bike at work yesterday. I just didn't wanna deal with the choice of a successful repair or pedalling my bike home after dark. Today, I borrowed my wife's dear friend/my coworker's truck and brought my motorized bicycle home. She warned me not to fill her gas tank. The last time I borrowed it to do a short errand, I pumped $47 into it. She treated me to lunch because she felt guilty. I dunno why she feels guilty; I know I can ALWAYS borrow her truck.

It was time to trim the herd, so I put an old Giant bike in the truck for her when I returned it.

I'm on vacation, so I'll have time to fix it. In fact, it's 1:30am and I had 5 hours' sleep.

Might as well work on my baby now. It's nice to have her home safe.

Update: The 8mm engine drive chain is 4 feet. Eight feet of chain and 4 master links were ordered, as well as a new bicycle chain, all on ebay.

Welcome back Skarrd!

Took my clutch cover off to inspect wear. Looked ok..

Here is a pict or too of my air box.. Noise silencer. http://motorbicycling.com/f47/goats-...tml#post350784

Works pretty good.

I'm interested in lowering the sound volume or frequency, if anybody knows how, without damaging the engine (Tanaka 33 friction drive). I am thinking of trying a few feet of heater hose or silicone hose. If it doesn't quiet it, maybe it will change the sound. I've seen a lot of bikes running rubber hoses on the ends of happytime mufflers. Please send links if you know of anything.
I have run 39" of silicon exhaust hose and a cigar muffler from the OEM muffler/motor in center-frame position, past the rear axle.

You could try fabbing a muffler outa a tin can and steel wool.

Quick trip over to the park for a bit of metal detecting.
Hit abt a dozen targets in 45min, or so.
Didn't need to call for an armored truck and guards to carry the loot home. lol

The motorized bicycle has good power through the rpm band now, but it's just too rich.
I can't see where a cns can ever be adjusted perfectly, or close to it.
Perhaps I need to make btr adjustment to the idle mixture adjustment screw???

I did find my Schwinn 12 function bike computer!
Might install it today... got other probs...
Squeeky noise coming from the handlebar stem where it foes down into the top of the neck. I HAVE seen 'em break off on non-powered bikes, so THAT should get attention first.

CHAIN LUBE:

A short time ago I bought Liquid Wrench brand.
Did NOT like how it sprayed on... even with the little tube thingy, it went all over the place and wasted quite a bit of the spray, getting lost on the shields I had put in position, just for that reason. (card stock & rags)

I DID let it set overnight, before riding it.
It soaked in well, really made a noticeable improvement in chain noise and pulsing.

What I would like to comment on, today, is that it has NOT slung off the chain while in use. VERY GOOD !

I have rim brakes and do NOT want lube slinging onto my wheel !!!

The Liquid Wrench chain lube product IS black.... but it isn't getting on the rim. I like it!

Happy:

It should not be difficult to make a non-restrictive glass-pack muffler to add onto your existing pipe...
Get some sort of tube a little larger than your exhaust pipe and wrap a layer of 1/4" mesh hardware cloth or expanded metal around the tube, which will be used for a mandrel, and removed, upon completion.
Then give it a wrap of common household fiberglass insulation. Loose. Don't wrap it tightly.
Make the fiberglass wrap a diameter you can slip into a can the size of your choice... a 24oz bud can would be kool... :-)
Hole at the exit end should be abt twice what the inlet end is.

Give it a try using coat hanger wire, to hold it together, and to mount it to see if it effective for you... no $'s... then you can decide if it brings the effect you are looking for.

Best

I don't know if mine air filter even makes a diff I was idkleing the other day
"A feat in itself" I figured I want to see if I can choke it out by covering the 4 holes on the "black scull" air filter cover So I covered all 4 holes and nothing it just kept on running ten I got down looked at it then covered the holes again still just kept on running I couldn't block the air going into the carb to save my life

Well I was feeling ambitious so I ported and polished my intake, shortened the studs to the head (noticed a lil blow by on the fins. figured the accorn nuts were bottoming out) shortened the intake studs and grinded the weld down so lock washers and nut would sit flat. and shortened my chain so I could get rid of the tensioner. With the porting and polishing bike increased in speed from 30mph to 37mph! well worth the effort. I live in the mountains of N.C. so climbing is more important than top speed, so this allows me to go to a slightly larger sprocket. currently running stock 41 thinking about 45. Unfortunitly to make to chain work without the tensioner I'm going to have to get some half links, ans since I already popped the chain that means no motorized bicycle riding til parts come in.
God Speed, Mark
