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

    I made a new front motor mount from 1/4" aluminum. Now the chain can be adjusted. All it takes is 1/4-3/8" adjustment. Just finished @ 2am.

    Can't wait for daylight to commute to work!xct2

    got a new spark plug in that should prove much better than a normal plug.

    i'll let the pictures do the talking.

    it's a NGK BU8H

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

    Finally had a break in the weather so I got to ride to work today. Good run each way, had to tighten a couple of spokes before heading home, but that's why the spoke wrench lives on the 'biner with my keys. It's the original rim, so a few loosen up a bit sometimes.
    It still has that 'new muffler smell' but that should fade in a couple more rides. I haven't got the lights aimed quite right yet. They helped in the blind curve, but aren't throwing the light far enough ahead for me right now.

    Please let us know how it works out.
    That is quite an interesting looking plug for use in an engine.
    It resembles a mechanic's test plug.

    The plug sure fills the hole a lot better than a stock one, skaard! I'll bet it even bumps the compression a tad. Wonder if the coil has enuff poop to drive that plug???

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

    Fours of sleep and I was biking to work. Previously the chain was as tight as "high G" on a guitar! After the new motor mount was installed, chain adjustment was good. Tension was the same at day's end. Previously, with the old mount and a Chinese freewheel, the chain would tense and loosen within a few strokes, then tense up again. Now, chain tension is spot on and consistent. i can sense there is less undue tension on the chain, freewheel, sprocket, even the bottom bracket cartridge.

    The ride to and from work went without incident. You never know how the commute will go without a test ride.

    I had been searching locally for M6-80mm length allen bolts for years. The correct bolts were found on McMaster-Carr reasonably priced. They arrived today and were quickly installed.

    I can't wait for daylight and my commute to work!xct2

    I rolled it out the back door of my garage so I would have room to work on my air compressor.

    MM gen 2 head: check
    BU8H NGK plug: check
    Piston to head clearance: check
    dellorto clone carb: check

    *starts bike* super low compression (didn't let rtv cure long enough)
    me: balls to it.. *keeps pedaling until engine starts catching. then give a gentle lap around neighborhood, stops, checks the bike. starts it (harder to start this time).*

    *gave it gas*
    me: HOLY S***!!! *hangs on for dear life!!!*

    verdict... this bike owns my last build now!

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

    Got stainless steel tubing for exhaust system out back of motorbike. 3 ft with 3/4 thread and two adapters to add at ends to make it to 1/2 pipe thread on the Briggs engine/spark arrestor muffler. Just will remove the rubber gasket for the water pipe use and put the Permatex 700 F copper forma-gasket stuff on the threads. Also go the clamps that I can hang the tube along with other brackets that I already have for assorted stuff to do on the bike. About $44 for the stuff for todays purchases.

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

    For my birthday today I got 68 degree weather! So I took the bike out for a spin. Stopped by the local NAPA and showed the fellows what I've been doing with the parts I've been buying there. They loved the bike. I got some interesting looks from the other customers also. Fun day. Nice ride. Pretty good birthday.

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

    Woohoo! This mid-sixties weather in January is the bomb! I've been out and about lately, just puttin' around the neighborhood. And answering the occasional question of "What is that?" with a simple "It's a motorbike." I love doing that.

    BTW: Thanks guys for the birthday wishes. For all I've been through, on good days I don't feel that much older (until I look in a mirror, which I only do when I have to).

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

    I started work on my chainguard, using generic aluminum channel. There's a LOT of exposed chain when you use a Scooterguy mount.

    Also working on my shoulder strap. I'll be using this to carry my bike up 2 flights of stairs after every ride.

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

    Got the seat tube adapter to use the Dynacraft seat and post in the LA Cycle's BigMo I'm fixing to sell. The BigMo has a 31.5 post hole and the LTD post is 25.5mm. I'm sitting on the bike and notice the chain side crankarm is bent in :p I'll be getting the BIG pipe wrench out to bend it back out. Then chain it to the gas pipe in the front yard and sell it :)

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

    congrats on getting it running, R_M!
    I had the same problem when I got mine going....I had to adjust the motor mount so it tilted forward a little, & then I also opened the drive sprocket cover & used a file to wear down the parts (a little) where the chain was grinding against the motor. Your problem might be different, but those are decent places to start.
    DEFINITELY get those brakes fixed lol have fun

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

    Rode around for 45 minutes recording with my playsport zx5 in my phones holster clipped to my brake cable. Really shaky vid, but youtubes' video editor cuts that down to a minimum. Got a few good "looks". Got chase by 2 dogs. Smaller dog was maybe a lil' over a foot long, 2nd dog was a good 3 foot long, and about 1 ft wide. The smaller dog was trying to get himself ran over by my front tire. Before i saw them, i heard barking, and as i got to a coldesac, this small dog come barrelling out of his owners drive way, with his friend not far behind. Both barking the whole time, the bigger dog ran a good 2 ft to my left for about 30ft then gave up the chase, the smaller dog snagged my pants leg and then let go(so glad). I didn't want to have to pull his remains out of my rear chainstay and friction drive. The smaller dog kept getting closer and closer to my front wheel and then darting out right in front of my wheel, so i had to keep jamming on my brakes and swerving to the left cuz i was inches away from hitting mailboxes on my right side. I finally swerved quick enought that the smaller dog rolled over trying to turn back to his left and i gunned my engine and escaped. Fun little adventure. caught some air on speed bumps. :) Top speed so far: 26.4mph
