    Installed a remote fuel tank on my Staton friction drive.

    Purchased Damp Pro dampening material, Grim Works Happy Pipe expansion chamber, lime green hp plug wire, and two 26" x 3" Kenda Flame tires (w/matching tubes of course!) All for my new GT-2 frame!! Can't wait!!

    I let it collect dust in my garage while I went to work.
    I want to get a better LED headlight, and those tend to cost around $100.00
    My $35.00 spotlight works fine, it just looks....wrong.

    A few days ago, the Scooterguy front pivot mounting stud snapped. I took some time off this morning to replace the all-thread mounting to a 7/16 x 3" Grade 8 bolt. That should work well.

    I also adjusted the front and rear 203mm disc brakes. They work par excellence.dance1

    On the way home, I pulled into a Chevron gas station and pumped 3/4 gallon of 87 octane. Two ounces of oil is kept in my 18 oz aluminum bottle in my cage. Before filling, I mix about 12 oz gas in the bottle, then slowly pour the oil mix in, while pumping gas. I had been filling a gallon of gas every 8-9 days. However, it got messy and overflowed, especially if there were more than a few ounces in the tank. Now, I simply fill 3/4 gallon with no messy spills. That amount should last me 6-7 days.
    I'm glad I swapped the chainring sprocket from 63t to 72t. Now even 8th gear is usable on flat ground.

    I've also been "tucking in" at speeds over 30 mph. I can REALLY feel the difference in the bike's performance. The Tanaka 47R engine seems to be pulling more at higher speeds.xct2

    was successful in jamming the chain inside the motor.

    wonder how people are able to get the chain running so smooth on the OCC chopper bikes. i made sure this time i built it that i got the offset mount for it.

    Replaced my seal, put heater hose between tensioner and frame.

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

    found out that the motor mount has been twisting when the motor is running. gonna get it aligned again tomorrow, then take the motor off, and drill a hole through the mount and the frame, then put a large bolt through it.

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

    I was thinking the same thing, but something like ceramic.

    I am also wondering if using the NGK BPR7HIX Iridium IX plug might be the cause. It has the most heat transfer from the cylinder to the head I could find, which seemed to make sense considering my extreme heat riding conditions this time of year and usually always running the motor (via gears) in the top 1/3 of the RPM power band.

    Then again maybe I am running too lean now, I'll pull the plug and check it, then just pop in a stock LD Z8C and Z4JC plugs and see how it runs.

    Don't you hate it when more than one condition has changed when a problem occurs?

    In my case a different plug heat rating, a different oil and gas/oil mix, and the ambient temperature is ridiculously hot to start with.

    One thing is for sure, it sure as heck performs like a full race motor until it gets hot.
    0-30 in a heratbeat, and much faster than I typically want to ride.

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

    Contemplated, ...
    half a cigar's worth. .. .
    The problem with inheriting a project, no matter how cool, is the family politics that go along with it. I'm thinking I'm gonna start with a fresh engine kit and a fresh bike, paint it the same color and see if anyone notices. It'll be a "tribute bike" I'm thinking.
    I'm absolutely sure I've spent like 4 to the 3'rd power more time siting on a milk crate contemplating the possibilities and smoking cigars than I have actually riding my bike . . .
    In the end it's all joy I guess!

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

    I love doing just that. Cup of coffee or a libation, a smoke and just sit (also on a milk crate. is the perfect height) and just contemplate. "Medi-engineering" ("engi-meditation"?)

    Oh man! On an early Sunday morning. No one but the birds, the bike and me.
    A perfect day....

    Not so much what I did To my motorbike today more so what happened with my and my motorbike today. I ran out of gas. Bummer to say the least. About 3 miles from my truck. I peddle back and man I will tell you, on a 100 degree day easiest gear felt like top gear. My bike sounds like a freggin TANK! You can hear me peddling up on you.

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

    Broke a ring and stuck the piston. I was only 12 miles out, mostly up hill. Lol. Looks like I will be doing some polishing on some bearings, piston, rings, rod, wristpin. The whole topend. For the 4th of July weekend.
    Im hoping I can find better bearings. Maybe better piston and ring.
    Does anyone know of better then china piston and rings for a grubee 66cc.?
    Im sure the bearings will be easy. There are a bunch of bearing houses around here.

    Just about every online retailer carries them. Check out the links on the sides of the page.

    If only we could get a group buy on having Wiseco make pistons for these little engines.
    It's too bad that there are 3 different pistons all marketed to fit "66cc".
    It would become a nightmare!

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

    Well, when we're dealing with diff. manufacturers motors, get parts from a retailer of that motor. If it's a Grubee, go with BikeBerry or GasBike, if it's a Raw, get it from Raw. Etc etc.

    Though, it would be nice to have some custom stuff made - I myself would like a custom machined 48cc hemi with a shortened skirt on the intake side.

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

    sat on the plastic dog food dispenser and re-engineered the tensioner...the flat spots that allow it to be tightened without turning inside were rounded and it kept coming loose...put a couple washers on the inside to make the large boss..."stick out" (so i could get a vise grip on it) then put a skateboard wheel bearing on the inside...to help with the off center bearing placement....(ground to proper width...and drilled....tightened it all up...and wallah! a chain that stays taunt. I'm soooo happy.
    also put my 7 speed derailer on the bike chain as a "tensioner"...works great as well.
