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

I was lucky with installing weaker springs in my centrifugal clutch. With weaker springs the clutch engages just above idle for a smooth takeoff and no jerks. The transition between shifts is also very smooth now. The bike is so much more fun to ride that I probably won't be able to finish the rest of my projects!!!!! This solution will work on any clutch that engages too slowly or with a jerk. I used springs that I had scavenged from discarded appliances or tools. The replacement springs were the same diameter as the originals, but the diameter of the wire is slightly smaller.

2 below farh. with 13 below wind chill had to get out the winter bike and winter motor. Spent 12 hours couple of days ago stripping the summer bike and prepairing the winter one.
Today I finished up and took it for a spin up and down the alley and around the block and it's running ok with alot of bottom end power- that tiny little motor sat all summer- I sure am happy that it fired up!!!! After the test ride, I let it sit and idle for a long time.
Still have some summer gass left that I gotta burn up-then it's time for sno-mo oil!!!
I cannot wait to try some of that Shell Advance.
These bikes are my only transportation so I gotta have them runnin- I cannot mess around. Well, all ready for the winter-they say that it's gettin warmer next week.....
YYYYAAAAAHHOOOOOO!!!!!

WoW ! THAT is COLD !
I just don't want to deal with that anymore! lol

Whew!

KC, yes, I should pop it apart to look, but I have no spare parts on hand. Not even a head gasket.
...if I bought a con rod bushing for a nickel, they'd probably want to charge me another nickel to mail it... wouldn't pay. and I'm not even sure if it is the wrist pin, or if it even uses a bushing, or a bearing.
The top end kits seem to come with a piston and rings, but no wrist pin or bearing???

Any advice on cheapest barrel WITH piston, rings, wrist pin & ... well, I don't know if my 48cc skyhawk is bushed or not! ???

From ded cold, I set the plunger choke on, it starts in the first 5ft and runs for a warm-up 300-400ft, then I can take the choke off and run a mile or so to the market or hardware store. It's still reliable. I don't want to give it up ! lol

m8r... U did the right thing! ...NOT going back out for another spin... always good to set and look at things, (especially after something has broken), when you're enjoying the excitement of that first ride! :-)
...the slide in your carby may be position incorrectly...
with the spring OFF, you should be able to move the slide up and down quite freely with the cable end... if not, be sure it's rotated for proper alignment of the groove.
the groove goes towards the drive chain side... the small ramp at the bottom of the slide is for the idle speed adjustment and goes towards the clutch side of the engine.

I went up to the hardware and bought replacement screws for the parcel rack I took off a parts bike yesterday. Will change 'em out tomorrow. Don't want it to end up like a floppy fender boggled up in the back wheel ! Ever !!!
I'm a big spender... 40 cents a piece for #5 metric screws and a dime each for washers!

Best

I am not sure, but I think it is just the shoes chattering against the drum when it is at an engine speed that is just not quite enough to stretch the spring hard and fully engage the shoes. It's a 2 shoe clutch (tanaka) so I think they are just bouncing back and forth when it does that.

I have a duplicate motor and I am going to put it on another Dax drive. If it does not do that, I would suspect it is the drum then. The drum does not visibly deviate when turned by hand, and it does not move left or right, as it is locked in place tight by the 1" roller with set screws.

I have had similar issues with both my BMP kit & 2 Staton double bearing clutch drivers. It wasn't the clutch shoes or the bearings, but a loose/wobbly drum. On the BMP kit, I had to install an extra 1/2" washer which allows the shaft-end screw to remove excess play from the 1/2" shaft removing drum play. On both Staton drivers, there is no threaded end to the shafts, but by removing the driver, laying it flat on the ground & installing one to two extra 5/8" washers between the pulley & bearing & pushing down on it while locking the pulley set screw, it also removes the play allowing the drum to spin totally true...

I rode my Schwinn Avenue cyclocross bike with no motor kit today, on some mtb trails. It was fun, but not enough fun to deter me from putting it back on motorized bicycle commuter duty when I get the other Dax kit (1st one moved to wife's bike in hopes of getting her butt off the couch).

The low bottom bracket makes this bike less than stellar for off road riding, but the low stand-over height is great. It is very fast on singletrack type trails but is limited by the narrow (700x38) tires.

Hahha. I like the Metric System, but I have not gotten used to Kilometers per Hour or Degrees Celsius yet. When you said 34 degrees in Melbourne, I was thinking, how odd. It should be summer weather there. Then I remembered....

Also check the routing of your throttle cable.. too many tight turns and it will bind up in the cable sheath. There's a good thread around here on shortening the throttle cable, I haven't tried yet but it's on my to-do list when I get my hands on a bit of silver solder, which is around $10 from many retailers. Last time I looked the place I went to was actually sold out, so the project will wait until I'm there again.

I'm from the switch-over generation here in Canada, they started teaching us the old way, then told us to forget that and shoved the metric system on us. I use both in different areas, feet and inches for short/project measurement, kms for driving distance... Pounds more often than kilos (outside work, where I have to use both for shipping). The place it works out best (for me) though has to be liquid measures.. so much easier to make up gas/oil mix with a base-10 decimal system than with gallons and ounces.

I use a couple of different sites for converting units, this one: Metric-Conversions.org, and Master Unit Converter. They cover everything I've needed to convert (so far). As a rough rule of thumb, 10 km=6(.2) mi.

Today is clear and sunny, but cold. Close to freezing, there's still frost in the shadow of the house. However I'm going to gear up and take the new motor out for a 'confidence run' in a little while. Once I'm happy with it I'll feel better about riding out to go to work in the dark @ 7am.
