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

If I drive like I stole it to work, I get 94mpg. That's with a Tanaka 47R racing engine on my motorized bike, speeds up to 45mph.

If I drive like a sane person, I get 125mpg, and speeds up to 35mph. And less oil splatter.

Simply awesome!

If you are getting oil spray from the carb & filter, maybe you need a longer intake manifold or different filter box. My Tanaka 33 has a little foam donut for an air filter. Kind of hokey for a "$300" motor, but we'll see how it runs! (and if it drips lol)

My grubee didn't want to idle for anything, or idled really high, till I narrowed the plug gap a little. Now it can run the lights without lurching or killing it and starts easier.

Lol, I'm not changing any part of a perfectly engineered racing engine.

I'll just wipe it up. It might be coming from the slip-fit connections of the Tanaka three-piece pipe. I'll seal the pipes.

Today I had to adjust my brakes. The legislation for this region doesn't cover our bikes very well, it's geared mostly to electric and/or step-through frames. The only thing I did find that seemed consistent was a mandatory stopping distance of 9 m (29' 6") from 30 km/h (18 mp/h or so). I marked out a couple of stripes on the back lane and ran the bikes through it. The wife's stops in half the space. On mine, my brake cable had pulled itself under the edge of the tank and pinched between it and the crossbar, reducing my back braking power pretty badly. I loosened the tank and fished it out, and a couple of small cable ties now keep it pulled clear by going around the tank studs on that side. Now that it's freed up, I go over the end line by about a half a rim with no additional tweaking. That'll do for now.

After that we went out for a cruise over to check the PO Box, have a coffee and back. Around 20 km (12 mi), not bad. I did most of it barely above idle (30 kp/h/18 mp/h), since my wife's bike is a bit slower than mine, and that's where she's comfortable with it for now.

We stopped at the Canadian Tire for another bottle of 2-stroke oil and a few odds and ends on the way back. Answered questions everywhere we went, though not as many as we did on our trip towards downtown earlier in the week.

I'd close the plug gap a little as suggested...so it does not appear to be flooding out..or "loading up" as I've heard it called.

Mine is acting peculiar...if I pin the throttle open..it gets up to about 24mph...then if I close the petcock it starts screaming up to 32mph...just before it would start to cut out..if I open the petcock...it will stay screaming at 32....I think it has to do with the hotter engine being able to handle the extra fuel a "relatively" cold engine can not. I'm guessing though..oh and i've lowered the float so far if I go any lower it won't run right at all.

Put on some medium height narrow "ape hangers" today....because i bought a custom hand made gas tank yesterday and refuse to let it get dented by the handle bars.

I assembled my Dax Friction Drive with the Tanaka 33 that was listed for $89, and made my own remote throttle control/tester and plastic u-bolt to frame pads made of milk jug cut-outs. :-) What a wonderful day. Now just waiting for daylight to fire it up so the neighbors don't hate.

I'm using the bare cable, a little rough. Tip: thinner gear-specific cable works best, and shrink wrapping the cable after running it through the smaller hole (housing side) would probably help a lot, for finger comfort. The control works with 2 fingers or thumb easily. (do not grease cable where it touches fingers!) I am trying it out tomorrow, waiting for worm-clamp throttle lever from friend via USPS.

Interesting temp throttle. Simple enough in a pinch

Jumpa, you've gotta adjust your float to allow the fuel bowl to stay filled. You can also remove the gastank/petcock inline filter and put in a higher quality inline filter to improve flow at high rpm.

re: test throttle. Yeah, it was made to do until I get the plastic lever with hose clamp. I also plan to use one on my monster-tiller. This is a great test tool, as you can see where you want to install your lever, or run the motor while testing different handlebars or grips.

If you zip tie the cable to the stem or bar, or ziptie the tester to the bar or grip, it can function long term but it is a little wierd.

I got the idea from some custom brake levers on a high-end hand-built bicycle. There were two stalks per side of the handlebar, with a length of cable between them, and the brakes were actuated by pulling the cables with any fingers the rider chooses. Very cool! I could not duplicate them even in a rough fashion, so this was my there-I-fixed-it answer.
