    The car is fine. I have a garage full of parts, not worried about pulling engines and transmissions, swapping, welding stuff together. Silly thing will go forever with enough love.

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

    On my way to work, the 8mm(T8F) engine drive train jumped off the new 72t chainring sprocket. This happened atop a moderate hillside, the biggest obstacle along my daily route. I pulled over onto the sidewalk, wrapped the chain around the big sprocket and motored off to work. This all took less than a minute. I made a mental note to doublecheck this when I arrived home.

    I noticed that this larger sprocket greatly improves acceleration in low, medium and top end. In fact, the first three gears wind out very quickly, allowing me to better use the rest of the cassette's gearing. With this new sprocket, it is much easier to ride up the steep ramp at work.

    The 72t sprocket was well worth the $10 I paid for it on ebay.dance1

    I pulled into the Chevron station and refueled after work. Gas prices are dropping here. At $3.86/gallon, my bike took about $3.30 to fill the four-liter tank. I've been filling my tank every 8-9 days. That amounts to less than $15 a month to commute to work. Compare that to $500 monthly to operate a third vehicle in our family, plus the cost of buying a car.

    Traffic was gridlocked for a few blocks before my biggest hill, so I hopped onto the sidewalk and motored along at jogging speed. After that, it was smooth sailing uphill. Top speed on the hill's plateau exceeded 40 mph for a few seconds. This is in a 35 mph zone, which was still too slow to keep up with the cars. Nevertheless, I still claimed the lane and watched the drivers speed away. I guess they're all trying to make up for lost time, before they hit the next slowdown on their way home.xct2

    Upon reaching home, I always park under the cool shade tree. There, I wipe down my bike and check everything. I noticed that the pocket bike freewheel on the engine sprocket was loose and wobbly. This could account for the 8mm engine chain jumping off the new sprocket. I have a spare pocket bike freewheel ($12), which I'll install this weekend. I also inspected the frame's bottom bracket. The left-side adjustment looks flush with the frame, but the right side looks like it's sticking out about .060". The adjustment could be loose there. It could also be the fact that the frame took awful beatings from the chain repeatedly falling off and scraping the carp out of it. This all happened until I finally solved the chain jumping problem late last year. When I replace the freewheel, I'll inspect the bottom bracket.

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

    changed my c*appy brake pads, adjusted my chain tension, fixed my fuel leak problem, adjusted my floats, rejetted my carb, replaced all my fuel lines and filters, went to fill up at the gas station ($1.90) and answer about 20 questions about my bike.

    seem to have developed a new problem now, my rear wheel looks wobbly when its rollin so it might have a few bent spokes in it, need to find some replacements now...

    cheers!

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

    I took a nap this afternoon and woke up at 830 pm, feeling regreshed. The loose freewheel on my chainring sprocket was on my mind, so I decided to replace it. That would give me an opportunity to inspect the bottom bracket.
    Nothing was loose.The cartridge was installed slightly off in the bottom bracket, towards the chainring. I noticed that the same amount sticking out on the chainring side was sticking in on the left side of the bottom bracket.

    No big deal.

    After soaking the new pocket bike freewheel in oil, I installed it and reassembled the chainring sprockets. One of the Scooterguy mounting through studs was crossthreaded. This was the stud which pivots and secures the engine plate, so I replaced the stud and nuts.

    The sprocket on the pocket bike gear box seemed to have excessive side clearance on its shaft. A mental note was made to find a shim/washer to stabilize the 11t sprocket. Unfortunately, the Tanaka engine's exhaust pipe must be removed to get to that sprocket.

    Otherwise, everything is in place, and the bike is ready for today's commute in five hours.

    Can't wait for daylight!dance1

    LOL 5-7. If ya have waited for sun rise to ride your bike, ya might be a MBer"

    I am curious, do you always soak new parts in oil? I had never thought of that and am wondering.

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

    Rode the bike last night, looked it over and inspected to make sure nothing was coming off or loose. Waiting on my spark plug to arrive from SBP as mine is beginning to foul out so I'm losing power.

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

    Woke up, got out of bed, drug a comb across my head.. Went downstairs and had a cup..

    Seriously: I am waiting for the USPS and UPS Santa's to bring me my things.

    Lets see, a light is on the way. A SBP exhaust and hardware is on the way. Plus the handle bar accessory extenders ( to lift the lights above the front basket ) and an Air horn.

    The turn signal unit horn stopped working so I wonder why..

    My last trip was a 40 mile round trip to another town to eat. I thought where do I want to eat tonight and I took a chance a town far would surprise and satisfy and also it was my first night ride ( with a Walmart bike light ) but I made it. I am sure the brake light and blinking turn signals looked good in the dark to other drivers.

    The engine mounts loosened on the way and I had my first rear flat with a 2 inch long wood splinter going through the tire and tube.
    The Chinese food in that town was excellent and I will go back again!

    So in the mode of another Song .. Do Do Do looking out my backdoor..Come on Come on mr. Package delivery person..

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

    I hung out with the other alumns at my HS graduation. Toward the end very black clouds came in... So I gave the bike a good run for it's money home!!!

    I actually tuned it when it was 65 and dry, riding around today at 90 and really humid I had to re-tune! crazy. I don't usually have to re-tune until I ride it at 0 and below in the winter.

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

    LOL, I only ride during daylight hours. Old eyes and less chance of getting hit by cars.

    My friend Hawaii Ed used to commute from Ewa Beach to Pearl Harbor, almost 20 miles, all in traffic. That's a LONG way to dodge cars in Hawaii, and he rode at 230 am!xct2

    I don't usually soak parts in oil. However, the pocket bike freewheel is not serviceable. There is maybe a .005" clearance between the OD, which moves with the chainring sprocket and the ID which screws onto the crank arm. When I install the freewheel, most of the oil seeps out, so I try to push some grease through that .005" crack.

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

    When I rode up the ramp at work, a bystander thought that a go-kart was screaming up the ramp!xct2

    "Is that a motorcycle or bicycle" he asked.

    "Bicycle".

    "I thought a go-kart was coming up the ramp". he said.

    "Excellent observation. My engine came out of a Tanaka Powerkart. Most people would've guessed it was a weedwhacker engine".

    It turned out that my new friend used to race twin and three-engine Maico go-karts years ago.

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

    Cleaned up the porting inside the exhaust flange of my homemade exhaust and sanded the whole thing in preparation for the BBQ paint. Also started painting the muffler mounting bracket. Decided to try out Krylon Fusion paint since I have read many good reviews on it. The can says it is good for plastic, metal, wood, wicker and more. No primer needed.
    So far I can say that it comes out extremely watery thin, runs easily and has poor coverage. I only spray paint things with many light "dusting" coats. Seems to be more durable that way. I have applied 6 coats and I can still see through it. Maby after the whole can is used up it will cover and color better? I will find out tomorrow!
