Looking to start and finish the exhust this weekend if I can get the wife out of the house long enough Got done with the new cool head cylinder head... anodized red to match the bike, cut the body work up, got the new splined kick start extender back form the machine shop...

    Ok, got the pipe built, does not look to pretty right now as its black parts with silver parts. Going to sand blast it all down and paint it black. Ill snap a picture when done. Only took 16 hours to make the pipe/Brackets etc... LOL
    Grind, weld, Grind, Cut, Grind...Grind some more...What a pain. Fits perfect, plenty of clearnce, high mount like a GP bike....Looks slick... Overall length is a few inches shorter than the orginal cr500 Pipe. This will help move the powerband up the ladder a bit....

Engine sounded very nice....to my suprise...I did not feel any vibration, Yahooooo... Once I get the hang of starting it ill get another video....Stay tuned!

    ran it more tonight...definatly lots of vibration. I might need to wire everything LOL. All the loose bolts hit the ground after a minute of reving it up...Good news is that it didnt seem to loosen up the important bolts LOL
    Kinda loud but not louder than a harley...Ill get a video of it once I can start it easier...

    loctite and wire EVERYTHING. My 125 liked to loosen seat bolts even with loctite! I think the 500 vibrates even more. I'd put some serious gel grips on and think about filling the handlebars with sand...

    Any instruments should have some vibe damper in place as well or they will simply crack.

    Looking for custom expansion chamber built

    I Know....Belive it or not the handlebars felt fine even though I will put on the foam superbike grips I put on all my bikes. I did feel the tank vibrating alot as well as the windshield...That thing was oscillating big time. I think Im going to pass on the Gauges until I start to ride it a bit. Seems like the Gauge could fall apart fast... I will remove the upper engine mounts and see if it helps. If it does help then I will replace the hard rubber upper mounts with much softer rubber. Im wondering how bad the body work is going to shake! The only bolts the fell off were the ones I forgot to tighten...Vibration was bad but cant say it was horibble.. Idleing and reving are a bit diffrent than riding on the road. Im not going to put any more money into it until I drive it on the street and see if it says together... Video of running should be coming tommorrow. I think i figured how to start it. Seems very much like my wead wacker LOL. Choke it, kick two times, choke off, open 1/4 throttle and kick away. All other methods Ive tried ended up flooding it....
    See ya!

    RING-A-DING-DING-DING

    Very nice

    Just wondering though, are you gonna have a hard time getting it inspected? Is it technically legal to run a 2 smoke on the street? What are you gonna do for a long ride, keep 2 stroke oil in your pocket and shake the bike around to mix it?
