I'm sure that most of the common people you'll meet on the street and when parked the bike have a different view than these show judges.
The Ariel and your CR750 can not be compared, totally different bikes. I'm sure many will put their vote on the Honda. I'm sure that ALL on this forum will... ;)

Vincent,

Jay (LaRossa) and Justin (Webster) agreed with me and loved your bike.  They are not only friends of mine but invited builders to the 1 Moto, Forged Invitational, Handbuilt Show, Quail and Outlier's Guild Moto shows.  Together, we could not understand why your bike did not win its class.  The Ariel did not belong in a Cafe/Street class.  I thought the judges got it wrong but, unfortunately, these things are subjective.

I'm betting the guy with the Ariel had his toes painted beneath that snazzy Street Race Footwear. It's those minute differences Vincent that make an award-ready entry  ;D

You know, it must be hard to pour yourself into the exacting efforts of re-creating something only to have some "Experts" determine it's significance. And they have not heard the immense pleasure of watching this thing come together with pictures documented by your thoughts. So forgive them, they know not what they do...

As Don said, I think I'd rather have the respect of professional builders like Jay and Dustin who know those details, have made these things with their own two hands than some guy with a clipboard. But thats just me.

If you're so shattered that you can't bring yourself to love that bike any longer, being a forum citizen, I'll pop right over and remove that eyesore from your garage so as not to extend your languishing in despair  ;) Just say the word-

It really is, an absolutely gorgeous work of mechanical art, Vincent. Really.

At Corsa Motoclassica this year, the bikes were judged by 2 people.  I didn't agree with their opinions nor did it appear that the attendees did either, as measured by the sheer interest in the CR build all day long.

Many times, it is down to the subjective opinion or one or two people that decides who will win a show. 

I'm glad you brought the bike to Willow Springs.  It was appreciated by people who knew what they were looking at.  That's all you really should try to focus on.  I suppose 1st place trophies are nice, but that's not why you put 7 years of your life into building this bike.  You built it for YOU and you also have the respect of our members and other fellow vintage/race enthusiasts. 

Now get over to the BOTM board and accept your nomination so WE can vote on your bike.  http://forums.sohc4.net/index.php/topic,171897.0.html

I hate to disseminate bad information! Don, I thought I was being introduced to Dustin Kott, and then I wrote it here on the forum. I guess I was so hyped about being in a show that I wasn't listening clearly to what you said. And then, of course, there's the cumulative hearing damage caused by years of motorcycles, power tools, and rock 'n' roll music. So, for anyone who thinks I met Dustin Kott: no. Different guy. Justin Webster.

Thanks again to everyone for your support. And calj7373, I'll just leave my poor-excuse-for-a-bobber motorcycle out at the curb. Pick it up whenever you can.

No worries.  I'm not sure if Dustin has been invited to the Quail this year or before.  JUSTIN has been showing bikes at the Handbuilt for few years and the OG show last year.  We were talking about how a big show like that can give a new builder the confidence and exposure to launch a business.  For Justin, it was selling parts to Dime City Cycles and getting an invite to the Handbuilt Show that launched his business. 

I think that just being an invited builder to the Quail is a big deal and anything else (experience awards etc) from the show is gravy.

Have a great show!

That bike is a time machine for many. 100% sure that many old guys will comment your bike and remember the old days when CR750 ruled the race tracks. Let them talk and remember the old days ;) Fun to see their happiness remember....

I get many good comments about my CB750K6-76 from people with memories of the 70's. "It look like a mint stock bike, a real survivor" etc etc. "I had a friend with a CB750 early 70's... I had one..."

Those judges should be crazy about my CB750.... not stock, not stock. Honda did not do that...color too dark sapphire blue, cylinder is wrong, carbs, holy pods !.... But that does not change my feeling or all others that see the bike.

You've created a beautiful machine, Vincent! Remember that criticism says as much about the critic as it does about the object being criticized. The fact that judges chose the bobber over your build says a lot about them and not your bike.

Don't let it bother you! dj

I hate bike shows, and folks who own show bikes, only for the purpose of showing them. Bikes are meant to be ridden, not trailered to a show and parked like statues in an art gallery, so their owners can waffle on about them to anyone who'll listen, stab each other in the back for a pissy plastic trophy, then trailer them home again.

Fcuk bike shows, get out in the wind and enjoy that bike Vincent, it's a motorcycle, not a fcuking statue......... ;D
I was feeling sorry for myself because I couldn't afford new bike boots, until I met a man with no legs.

So I said, "Hey mate, you haven't got any bike boots you don't need, do you?"

Wow Vincent!!! What a beautiful bike!!! I couldn't agree with you more the cr750 is by far one of the most sexist bikes ever made and definitely my favorite. I could only hope one day to have the time and resources to create a masterpiece like yours.

It would have been a heck of a battle if H2Eric's CR race replica went head to head with Vincent's CR street bike.  I'll take one of each!

I've seen a lot of really nice Bike of The Month winners, and it's an honor to be in their company. Thanks to everyone who helped make that happen.

I've hesitated to come here with a problem, because I have this thing about wanting to figure everything out for myself. All that has brought me so far is a lingering problem with no solution in sight. This is the second electrical problem, and I'm happy to say the first one was solved by my friend Mike. But first, here's a sample of Mike's talent for finding solid, proven methods for handling wiring woes:



Pure genius, no? Anyway, back to the story. I would charge my Shorai battery up to about 13.5 volts, start the engine, and see the voltage go down to about 12.5. I found continuity between the white and green field coil wires and ground, but when I removed the field coil from the alternator cover, there was no continuity between the wires and the coil body. Screwed it back into the cover, and there was continuity again. Out again, and no continuity. Mike screwed in one of the screws that held it into the cover, and there was continuity between the screw and the coil body. Backed it out, and no continuity. I pulled out my parts manual and saw that the three screws are supposed to be 20mm long. I had replaced the stock screws with stainless flathead socket screws, and the store only had 30 mm screws. I poked a little rod into the hole, saw that there was room for 30mm, and thought, OK, I don't have to cut the screw down. Turns out the screw was long enough to make contact with the core of the coil, resulting in continuity and preventing charging. So that's over. Now the bike charges, but there is another problem that still remains. Since the battery ran down several times, I keep the charger handy. The bike can sit with a fully charged battery for a couple of days, but it can also suddenly drop to about 6.5 volts, and nothing will work. Since it's intermittent, I have no idea when - or where - to start looking. When the charge is full, I have working headlight, instrument lights, tail light, brake light, and horns, so there's no obvious culprit. I had taken off the fairing and front sprocket cover to access the alternator, and when I was done I went out for a short early-evening ride yesterday. Stayed around the neighborhood, so I was within pushing distance of home if things went bad.



Big fun. And big noise! But when I pushed it out to the street this evening for another ride, nothing worked, and the meter said 6.7 volts. But being a hard-headed (foolish?) person, I'm determined to ride to The Rock Store tomorrow morning, and then on up to Neptune's Net for lunch. It's been so long, and all I can think about lately is riding the thing! I'll be riding with my friend Will, so at least I'll have company if I wind up waiting for Hagerty Insurance to send out a roll-away truck.

So. I showed the bike at The Quail a few weeks ago, and here's a picture from shortly after the gates opened.



It was a great day, and there were tons of beautiful bikes. The judges came by in their blue blazers and straw hats, and they asked questions and had lots of nice things to say. They loved the tail light, and one of them said it was the nicest tail light he had ever seen on a CR seat. But then he asked me why the bike wasn't in Cafe Racer class. I said that when I filled out the forms to enter the bike, there was a list of classes that included Cafe Racer, Competition Street, and Custom. Not being a show person, I had no idea which class was appropriate for the bike, so I checked the box that said The Quail organizers could put it where it belonged. Well, they put it in Japanese 1937-1979, and when I arrived they gave me a little plaque to put on the lawn in front of the bike. That was the end of that. The bike that won in Japanese class was a totally restored gold '72 CB750 with NOS painted parts.



The bike that won the Cafe Racer class was a 1961 BAS Gold Star.



They were the right bikes to win in those classes. And Terry, I agree with you about bikes being meant to be ridden. Otherwise, they're just statues.

OK, now I'm off to a night of tossing and turning in anticipation of riding the bike. And hopefully not breaking down. It still only has 5.6 miles on it!

Vince, something must be discharging the battery when the bike is sitting? 6.7 volts is extremely low for an LiFe battery, and may have damaged it. :(
Don't fix it if it ain't broke!

Vincent,

Lithium based batteries, once they drop below a threshold voltage level, will NEVER retain full charge.  It's their Achilles' heel.  I've had 2 die this way.  After they dropped below the level, it did not matter how long I charged them.  As soon as I took the batteries off the tender, they would start falling off.  The symptoms you are describing sound extremely familiar.  If this happens tomorrow, I would recommend inspecting/replacing the battery.

Disconnect the negative battery terminal when the bike sits overnight, until you find out what's draining it. Are you using an M-unit?
Don't fix it if it ain't broke!

I believe he is, and an M-Lock too.

I suspect that he drained the Shorai with the HI switch not deactivated when killing the bike, then damaged the Shorai (as Don said). Time to replace the battery.

Vincent, whenever you activate the HI switch, you must return the headlight to LO before deactivating the M-Unit, else it will be a parasitic drain on the battery. This is documented in the manual in an obscure way so many fall victim to it.

Damn! I didn't know about that idiosyncrasy.  Good to know.
