OK, we've gotten considerably far off topic, but one more question:

Is there a way to turn that strange thing off? "Has a dragon in their garage", "Corbu blah blah blah", it appears under my name and in no way describes me. :shrug:

I meant pure oxygen instead of the normal intake air. Do I really present as that ignorant?  :???:

Off topic, I see that "Corbu is my Homeboy" is posted under my handle. Dafuq is a Corbu!?

Your post count title changes automatically. There is a unique one at 666. Blink and you'll miss it!

EDIT Ah you missed it.
Yes, Tank, but that doesn't answer the question, "Dafuq is a Corbu!?"
:shrug:

I didn't make make the list :Gaah:
:lol: OK.

"Like his contemporaries Frank Lloyd Wright and Mies van der Rohe, Le Corbusier lacked formal training as an architect."

Whitney was an architect, probably still is, Corbu was an admired figure.

Ooooo, I'm in the Petrol head thread!
Quick, lets get out of here before we get oil on our toes.
Take my advice, don't listen to me.

Lol. No you can't turn it off. But it will change when you reach the next posting milestone.

User ranks are just fun titles we give to users based on their post count.  The following is a list of those titles and the post counts associated with them:

Quote from: Recusant on October 18, 2015, 02:18:04 AM
Since I've been outed here (), I'll carry on with my plan and request further ideas for user ranks. Not sure regarding how high the possible limit on post count based ranks is; some further experimentation regarding that will be necessary. For instance, I tried to set "Guardian of Reason" at 25,000 posts, because that was a rank that Tank had requested years ago, and it didn't seem to work. I'll try it again, though, and maybe get it to stick, in which case we might end up with only one guardian of reason.

Some shuffling of the rank designations may take place, depending on the selection of titles that are suggested, and of course there's no guarantee that all titles offered will be used (I rejected at least one of my own earlier suggestions as not worthy, for instance). Though some of the fun is trying to figure out what the particularly gnomic ranks signify, I will also be willing to try to explain any that seem especially mysterious and/or vexing.

Above you will see that the not commonly lamented former member "AnimatedDirt" came up with a couple of more or less derogatory ranks "for the minority at HAF."

He had such a way about him, did AD.

Not interested in stuff like that--more in things you wouldn't mind having associated with your posts, perhaps for 500 or 1,000 of them. In other words, try to come up with the good shit, my fellow HAFians.

Although I deviously carried out the revival of HAF ranks without telling anybody, I did consult with Tank once it had been done, asking for any thoughts in re revision or addition. Same applies here for the membership in general, including advocacy for reviving any of the old ranks that got dropped.

Or, we could leave it as it is, for now.

:lol:

Don't underestimate Recusant's ability to surprise, I remember when he switched the User Rank tag to 'Silly Overlord' when I hit the...14,000 milestone I think? He acted quickly and stealthily. Recusant is not to be underestimated. :o

it's getting warm enough to brave the warehouse again.

tomorrow i take my cylinder head to the machine shop to explore some combustion chamber re-shaping.

the races in maine are in july. so far i have three children interested in riding a motorcycle over 100 mph.



more people have been to berlin than i have

billy rubin

two of them already have the little kawasaki up to 103 mph.



i need to work on suspension,gearing, and carburation, and we'll see whether they can take the overall record of 107.

billy rubin

all right. we've passed the equinox, and the peepers will be calling in 10 days. it's spring, and the first robin returned two weeksa ago, the fiorst redwinged blackbird last week, two killdeers and a meadowlark. at the same time, more or less.

i have just spent $400 each registering the two race bikes for the land speed races in maine this coming july. thanks heavens for pay pal credit. we're running a 1965 650 triumph bonneville in modified production gasoline, and  a 2012 250 kawsaki ninja in pure production 250 gasoline.

and tomorrow my cylinder head finally goes to my pet machinist. he has to re-work the combustion chamber that took a piston hit at 7000 rpm, and i then have to take the motor back down.

hats because tthere are four connecting rod bolts. i only remember tightening three of them. i am 99.9999 percent sure that i tightened the last bolt, but 99.9999 percent is not 100 percent. the whole thing is together, but it comes back down so i can look at that one bolt. then back up and it will be time to break in the new pistons.

the guy that makes my pistons told me that  i would use them up pretty quick. i thought he was exaggerating, but it turns out he was correct.

my machine has gone 135.259 mph, the fastest speed ever recorded for an old-school triumph bonneville. the overall record for any 650 british machine that burns gasoline is 139. if i can squeeze 140 out of this fifty-five year old motorcycle, it will have beaten every record in every class in which it could be entered. so we'll see.

in the meantime, i have two daughters and a son willing to aim for the 107 mph record on the 250 production OHC class, on our little kawasaki ninja. if they get comfortable, one of the three might get a shot at the riding the dinosaur.

Don't forget to pack the parachute.

parachutes are only required on cars over 170 mph. we won't be playing in that sandbox.

they're important for the faster classes, though. breedlove lost his at 500 mph in 1964, the year my machine was built:

3:36

oops

the machinist apprentice says my head has two bent valves and may need some seat re-work.

i didn't think it was that bad.

it's a unique head-- a 1973 9 1/2-bolt, which was built only for about six months. hard to find.

we'll see what they say when the boss looks it over.

Machinist? I think you need a plastic surgeon for that head job.

if it can be salvaged its the one i want. the head itself was not expenive, but its got some very finicky flow work, and tbat is hard to duplicate.

i have another head waiting in line at another specialist, but he's had it four years and i am not optimiztic that i will get it back in  time for july.

You guys are nuts BR.  So alright.  I like gear head nut cases but I do question their sanity ....including my own when I was so heavily into that sort of madness.

I do hope that the machinist is fully aware the the valve seats are a major part of the flow regime.  Port work is appropriate for someone who knows the business but  the shape of the valve seats and the cuts on the valves themselves must marry appropriately with the port work.  The valve seats largely determine the flow rate at low lift intervals.   It is common for the head work guys to quote maximum flow rate at such and such a water level....usually 25 inches.  BUT and Big But...........Cylinder filling is a matter of  gross volume that predominantly includes the low and mid  lift characteristics. 

In fact the top lift is almost instantaneous and the dwell time and flow rate between low and mid lift provides more O2 flow than those impressive top lift figures can.  The whole idea is to stuff as much air containing oxygen into the combustion chamber as the induction system can accommodate.  Full on race engines use a fuel air ratio in the 12.5 to one region.  Adiabatic ratio is normally 14.7 but that is for the family grocery getter.  You can stuff as much fuel as you want into the combustion chamber but it will not burn unless you give it enough oxygen to do the burn rate. SO we have to get a bunch of oxygen laden air into the the chamber.  Whereupon we can burn more fuel and we can produce more piston pressure.  Burn rate too, is a biggie.  Combustion chamber shapes with respect to valve seat locations and flow rates do determine whether the fuel is completely or efficiently burned or not.  When the fuel air flies out of that valve seat.....where does it go and is all the potential energy of the burn and heat producing process complete. Not likely but it is a concept worth exploring. 

If your port guy has a wet flow bench and takes account of the chamber flow distribution pattern, you are ahead of the game

Maine? Where in hell in Maine do they do LSR record stuff.  My impression of Maine is of Lobsters and chowders...make that Chowdahs. And of course there is L.L. Bean.
