Run Ivy Run: Fanny Pack

Took a nice run down Lake to Ashley's Cafe.  Has the perfect parking spot and outdoor seating.  They serve dry cappuccino, but I guess you can't have everything.

Felt like the idle was weak during the whole ride and when I got back, I just let it die at the garage.  Wouldn't hold idle for more than a minute.

Came back down in garage gear.  Battery was fine at about 6.28V.  Spark plug looked ok, though noticed it was a D8HA.  Checked the gas flow through the carb and that seemed fine, too.  Noticed that when it was not idling well, turning the throttle screw seemed to have no effect... interesting.

Decided to swap out the plug for a new D6HA.  Started it up and she seemed a little better.  Then dialed the air screw out from 2 1/4 turns to 3 1/4 turns and that had her running strong.  But a bit weird that the screw would need to come out that much. 

Not quite satisfied with that result.  Probably need to invest in an aftermarket carb (with the gas line on the right!).

After that. rigged up the new Hide&Drink tool roll using the leather strap from Springfield leather.  Bolted it using the holes for the fender.  Came out rather well, to be honest.  Not sure if it's the best look (hanging it off the bottom of the left side seat is still best, I think), but at least I can carry it now.

Finally tested the first version of the 3D printed cable guide and it was way too big (as expected).

3d Printing: Carb Displays

Finished the mounts for my carb "collection".

As of now, this includes:

1. British Amal (a matching pair)
2. Mikuni - plunger type
3. Dell'Orto from a Lambretta scooter
4. Bing
5. Solex (made by Mikuni)
6. Offset Mikuni (with the broken choke gate)
7. Offset Keihin

3d Printing: Intake Cap

Handy little intake cap, instead of trying to find a clean rag or sheet...

Run Ivy Run: Leaks, K&N test

K&N learnings...

• The RU-0100 filter barely fits, but she does RUN with it
• The RU-0060 filter also barely fits, and she RUNS with that, too
• The RU-0060 filter is 75MM high - whereas Roxy's is only 62MM!!  How did I get that measurement so wrong.
• Browsing the K&N site again and stumbled on "Vent Filters" as opposed to Air Filters, and found the shorty filter which I think Roxy uses.  Will know for sure in a week...

 Carb gasket learnings...

• There was definitely gas leaking from where the bottom half meets the top.
• I drained the carb using the carb catch but this time put a thick layer of duct tape around it (worked a treat)
• Thought I'd just replace the gasket with the Keyster one, but then realized the Keyster was too small (and realized that that's probably why I cut my own in the first place).  It kept the floats from actually moving.
• Pulled the gasket from the other Keihin carb only to realize that one was also DIY
• Tried pulling the gasket from the broken Mikuni, but only half a gasket was even there
• In the end, put in the DIY gasket from the other carb only because it looked to be in slightly better shape
• Will have to check again to see if it's still leaking... 

Petcock learnings...

• Unfortunately, there seems to be a very slow but steady gas leak coming from the petcock even when fully closed
• It leaks now because it's open at the end, but if it were attached to the carb, wouldn't it stop once the carb filled?
• Though having a petcock that doesn't actually stop the flow seems pretty pointless.
• There are 2 used ones in stock, but not sure of the condition.  Or maybe just need to disassemble and check this new one.

3d Printing: Transmission display

The tranny "cozy" was fun.  A lot of measurements and I'm honestly surprised it came out so well with minimal versions.  The frame locks together with 6mm bolts and then sits in the mount at a 45 degree angle for desktop display.

Also good for maintenance/education since the gears will turn and engage within the frame.

3D New Year!

3D printed a temporary carb mount!  Possibilities are endless...
