So, it's an aftermarket petcock. Which way is fuel ON and which way is RESERVE?

Custom upholstered seat. Added a slight bit more cushion. It'll do for now. Tank and speedo mount are next...

Swapped out the bell-end megaphone for a Dunstall-style reverse cone muffler and I'm wondering if I have it sticking out too far (about an inch beyond rear tire). The Dunstall-style muffler is definitely more muffled compared to the bell-end megaphone, and despite that it sounds like a better fit for my 550, I'm now missing the big roar of the bell-end...

Chopped the muffler and the downsize adapter a bit.
How's it look now? My neighbors, I think, appreciate the muffled noise.

 Tarozzi front fork brace is proving to make handling a little more stable which is a plus

calj, I agree. Muffler ending around mid-drum would be nice. Maybe I should have gotten a shorty muffler instead

So I think I figured out my petcock - up arrow is fuel, and down arrow is reserve.

During a night ride, I had to switch to reserve at around 200 miles on my trip odometer and I filled up 3.69 gallons at around 202 miles... If my math is correct, that comes out to 54.74 miles per gallon? Pretty sweet.

Currently still running stock size 38 pilots and 110 main jets.

Pretty cool.

Next on my list for this bike:

- toss out old ignition and relocate new/smaller key ignition
- figure out and mount Koso gauge to make a lower and tighter and more sturdy fit above/behind headlight bucket
- install USB socket
- finish stripping eBay fuel tank and decide on whether to punch in some knee indents or leave it and paint it some color
- keep riding because it is such a thrill

That looks sweet! I would be very pleased with the position of the muffler, I think you've nailed it!

Working up my courage to begin riding on the freeways here in LA and I notice quite a difference in high speed handling (upwards around +70mph) with/without the Tarozzi front fork brace (as well as having properly inflated tires) - the stability is good to have for sure. Otherwise, I'm taking it pretty easy and riding "behind the scenes" and fighting the urge and curiosity to split lanes - it'll be a while until I get the hang of that. But dang it, I love riding this bike! Baby kicks!

One of the challenges I face while at a stop, particularly when waiting for a traffic light to turn green (some interesting tricks I learned reading this wiki on getting the lights to change), is getting the gear to click from NEUTRAL to 1st gear. There've been stops where before the light is about to turn green, I'll pull in the clutch and stomp down like mad trying to engage the gear and I get nothing because it's stuck in N. I've stalled out in congested areas because of this; struggling while cars behind me start honking and wondering what the heck is up with me. For now, I found that while I'm at a stop in neutral, right before the light turns green, I can roll the bike slightly forward and somehow that will allow the gear to line up and engage into 1st (sound like I need a clutch adjustment?). This has worked well so far and I can deal with it for now but there have been other instances where I stall at a stop/start intersection and wish that I had HAZARD LIGHTS to allow others behind and around me to know that I'm (temporarily) stuck in a hard place.
Any links or instructions to mods where I can fit a relay/switch to allow for my blinkers to flash like hazards? Is this considered sacrilege?

Oooh, that wind noise is something fierce.  Looks like the bike is running stable at highway speed!!

It sounds like you need to adjust the clutch.

Thanks for the firm reminder, calj. The MSF Course is coming back to me now; they did cover that part about keeping the clutch in to escape for safety. Maybe I need a refresher? Understood - never stop at a light in NEUTRAL. Thank you.

bwaller, I have tried this and it's great for times it has worked but I've stalled at other instances and that's when I think it'd be great to have some hazard lights :-)

CB750, that wind is definitely fierce and I bet I've lost some inner ear follicles as a result of some light riding. I must invest in some better ear plugs. Any sworn-by brands out there? I'm currently trying a pair of Ear Peace earplugs but they may be fitting a tad small letting in some of that harsh wind/engine noise.
