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

    I also have a slight heat issue (no where like in Arizona I'm sure) and a couple of my ideas have been to make a tin shroud to go between the cylinder and carburetor to act as a sink and absorb some of the heat. I made a PHENOLIC insulator and it helped to a degree but as the carb is behind the jug it is getting blasted with all of the cylinder heat the fins disperse. I am really thinking of just turning the jug 180 degrees and having the carb in front no matter how much of a pain it is to reroute the exhaust and redo the cables and fuel lines...

    I modified an air cleaner assembly from a Campbell Hausfeld air compressor to fit on my NT carburetor. It is definitely quieter now and has a lower tone to it.
    Will post pics if there is any interest in it.

    Please do post pics GN. Took me forever to figure out how much sound was coming from the intake.

    The rubber muffler works great but is only half of it. (well, the louder half but not by much)

    Yeah, noise can be a drawback of having a high-flowing intake.
    I used an oilfill vent as an airfilter/intake on one of my bikes, and that thing made all kinds of noise when accelerating!

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

    I've just been riding my bike to and from work lately.xct2

    Having problems with second gear. Since gear ratios are very low, I have enough acceleration to skip every other gear.

    I bought a card key at my workplace parking structure today. I usually wiggle around the parking entrance arm at the bottom of the steep ramp. My engine has to be tuned well, and gear ratio must be low enough to climb a steep hill. Some of my MB's were not powerful enough to climb the ramp from a dead stop. Luckily, I was able to push my bike into the workplace elevator.

    Using the card key will allow me to lift the entrance arm. I will have a running start to ride up the very steep parking ramp..shft.

    IBesides my MB's, I will also be commuting to work with a Honda 150cc scooter. Both vehicles are allowed free parking, dance1

    Last night, I took the engine off and repainted it with some Black engine enamel. Today I got to put everything back in its place and on the bike and then I'm good for a ride.

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

    My car is in the shop for maintenance, so I'm riding my MB to the blood bank 4.5 miles away to donate platelets. I donate fluids there every other Saturday.

    If I had to pedal, I would not be riding my bike to the blood bank.

    To make a day of it, I'll fill up gas and motor 4 miles further to Ala Moana Park(near Waikiki) for lunch..

    in the FAST lane on the highway..xct2

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

    Had my cruiser stolen(YouTube - ‪She loves the cold!‬‏), grocery-getter's running strong. Switched to a 44 from 42 for some hauling power, building a trailer for her, might throw on a 56T.

    To replace the stolen bike, I've ordered a Friction 4-Stroke from a local(Southern Ontario, MotorBoys.com) good guy to throw on a full suspension bike I've had for a while. If the friction has enough torque I'll pull the trailer with that.

    Whatever I have I'll need speed, so If I ever see my cruiser I can pass him, then F*uck him up...

    No fun, but its gotta be done... :)

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

    So I get home from work,I have been driving the MB because the wifes car is down.I come to a stop and the motor dies ,no big deal just held it for 10 miles and its hot.I tried to start it to go to the store to get me a beer it is seized?I pulled the head not good,so I tore it down.I broke a ring on the way home a destroyed the piston and cylinder.My ipod was cranking AC/DC on the way home didnt hear it.
    :-||
    So I had a motor with a new piton and cylinder on it swaped it out and jumped on then poped it over bang the piston hit the top of the head and stoped turning over ?It lookes like the piston pin hole is a 1/4 " lower on the piston?So I had a piston and cylinder off that was used but in good shape so I put that on and wow sounds good and runs sweet.I took that down the road about 1/4 mile and the rod bearing blew and ended up in the intake port thus blowing the motor.I think I hurt the rod when I poped it with the wrong piston.
    :-||
    So now I put the my spare motor back together with the weird size piston then swap the hole motor out,not easy has a charging coil and had to change the side covers to the ones with flames.So I get it all together and try once more to make it to the store as I am getting thursty bye now.I get about the same spot as before running good and the chain snaps and wraps around the spokes taking out 3 and ripping my rear brake off.Now I am thursty pissed and my rim is trashed!!!
    .duh.
    I pushed the bike home to find the retaining clip for the master link on the ground were I was working on it,I hoped on my peddle bike and got my beer,
    going to give up for the day and drink my beer .Happy 4th hope your was better but mine was not a total loss still got my beer
