I enjoy being a citizen of the
United States of America.
I would like to say to all the Governments/ people in the world that oppress women, by denying them human rights.
"YES, I believe you are stupid."
And not just women but every Human being has the right to be the best they can be, and enjoy this life as much as they see fit.

Keihin carbs now doing great on my CB360

First. I do not recommend you try this mod on your bike.  
Messing w the carbs could kill your bike.  
And running her too lean could destroy your engine.

OK heres what I been up to these past couple weeks.  I feel confident I have all the bugs worked out of these Keihin carbs.

The biggest and most annoying problem I was having was the rich mid range rpms...3800 - 4300rpm zone.

She would pop and cutout...However, above 4500 she runs great.  
Watching the O2 sensor I installed I could see she was dropping as low as 9.5 to 1 on the Air/fuel ratio, during the mid range rpm.

Another issue was she was rich when cruising 65mph in 6th gear, (4800 rpm)

So, in order to fix this issue, here is what I did.


I found the feed hole in the Main Primary tube measured 1.15mm.
So, I cleaned them and shoved some flux in there.



I filled the tip w solder.
Just a guess, I drilled one out to .76mm and the other to .82mm.
After making a few laps terrorizing the village.  I found the .82mm to be perfect.
The .76 was too lean.  She died as I was slowing to a stop.  And was getting lean on midrange rpm WOT acceleration.  up to 15 to 1 A/F ratio, also she sounded flat and lacked power.

I drilled the .76 out to match the .82mm and viola.

No more popping and she is cruising 65mph at 12 to 1.  She doesn't hesitate on take off and returns to idle smoothly approaching a stop.  She has tons of power during acceleration, throughout the entire rpm range.  And sounds great.  Starting from a stop she can reach up to 15 to 1 A/F ratio, as the throttle is cracked.  But, only for a second or two, after that Acceleration averages 12 and 13 to 1.  All the way to redline.

I am delighted.  

So, here is the complete current jetting and mod concoction, I have.

NEW, Tensioner / slippers for the 360 will be shipping soon. sparckmoto.com




Big News from sparckmoto.com...



sparckmoto has placed the order for the tooling, molds, and prototypes, but the production run has not yet been ordered.
  
Place your pre-order now and get a big discount.

OK folks...

I know a lot of us have been after these for a while, so I've been working for about a month now to hash out the details of having them made, and we're finally to the point where we're ready to enter production. These slippers and tensioners are being designed after the original pieces, using OEM materials, so there should be very little difference between these units and the stock parts.

So while that's pretty awesome, the down side is that I need to scrape up $1000 for tooling costs and molds.

I'm hoping that there is enough interest in these that a pre-purchase will help to cover this initial outlay of funds.

So... without further ado... here we go:

Pre-purchase price for a single set will be $50 + shipping (shipping to be invoiced after the production run). More than one set is $40 per set and I'll cover the shipping costs. Final retail will be $75 per set, so you're seeing a significant savings by getting in early.

There's no set date (yet) for this pre-purchase period to end, but if/after we're able to raise $1000, I'll give everyone else another week and then I'll make payment to the manufacturer. At this point, they will do the initial tooling and molds and send some prototypes my way for testing. I'll need some volunteers with running Honda 360 engines that don't mind opening things up to run these new parts, and then again (possibly several times) to inspect the parts for wear and performance.

After the prototype parts have been verified, we will enter full production and everyone gets their orders. (Very) rough timeline on these is about two months, so I'm hoping to have these ready to ship out mid-summer.

If you're up for it, payment can be sent via paypal to sales@sparckmoto.com. PLEASE, PLEASE, PLEASE include a note in the payment specifying the purpose. That paypal account sees a lot of use and I don't want to miss anyone out.

I'm happy to answer any additional questions here, or by email at info@sparckmoto.com.

Thanks again for all the help with this,
Matt

Enough funds have been raised in order to place the order for the initial tooling and molds. Prototypes will be headed out way in a couple of weeks.

There is still time left to get your pre-order payment into place! sales@sparckmoto.com

The good and the bad.

Got a couple subjects to post this morning.

first, The Good.

Finally the weather cooperated enough to finish the shotgun project.  I am delighted w how it turned out.  
Heres a quick recap...


Old Harrington and Richardson "Bay State" .410 shotgun.  I am going to present this gun as a gift to my buddy Emerson when he turns 8 years old.
It has a cracked stock and its pretty rusted and pitted.
I purchased a scrap of Western Big leaf maple for this project.  From my buddy Tim.
Laying out both pieces on the maple to find the best grain to fit the wrist of the stock.  Ideally the grain should run parallel with the wrist.  You dont want it to cut across the wrist, this would create a weak area.


Roughed to form.
Inletting for the reciever.
Fitting and shaping.
Taking shape.
Ready to inlet the barrel groove into the forestock using a wood chisel.
ready to incise the barrel catch.
More chisel.
Properly fitted.
snap on smoothly and a nice snug fit.
After shaping it, I cracked it and had to start over and make another.   Grrrr.
So, I did everything you just saw a second time.


The new forestock, glass bedding.
Incise carved Em's initials into the stock.
Bright and Ready for browning.
The browning turned out poorly due to low humidity.
Bright and ready for browning...Again.  Uggg.
Finished and fully assembled.








I am delighted w the results.
I think Emerson will like it.
And now part 2....  the BAD.

The Thaw is less than two weeks now...

I found one of the header studs snapped off inside the head.


So the past couple days I have been heating w the torch and soaking it with penetrating fluid.
Last night I center punched it.
Drilled a 3/32 pilot hole all the way through til I hit aluminum.  The old lady standing over me helping to keep it on the right angle.  I dont believe I got into any of the threads.
Over an inch deep.
Comparing the bit to the other stud they seem to be pretty close to parallel.
Now I am waiting for the delivery man to drop off the left hand carbide bits and extractors I ordered.

to be continued...I should now more this evening.

What is brat style?

Brat Style, is a motorcycle shop located in Japan.

They sell customized and used bikes, of all makes and models.


Brat Style shop

If one thing has come to separate a "Brat Style" bike here in the United States, from say a Cafe or a Bobber.  I would say it has to be the seat.


HD customized by the Brat Style shop in Japan.
 The seats are customized shorter, thinner and flatter than the original seat.  Im sure this style has taken off in Japan because they are small and relatively inexpensive to own and operate. It makes sense, these small vintage bikes fit the bill perfectly for a young, Japanese couple, just starting out in life.  They are reliable, parts are pretty abundant.  They may want a cool, hip ride to cruise around town yet still be able to ride two up. 


Custom Yamaha built at the Brat Style shop.
  
I use the term "One a and a half "  When someone asks about the seat I designed for my bike.   Due to the fact that these seats may be  perfectly suited for a 120lb dude and his 95lb girlfriends japanese butts,  they only fit about 1 1/2 or less full size American butts. 


Another Yamaha from the Brat Style shop.

 I decided to go "Brat Style" with my bike because the typical Cafe style seat, with its 1/2 inch foam pad, just looks like...Well...a pain in the butt.  I wanted a little more comfort than the traditional Cafe seat has to offer.  And mine has 2 inches of wonder gel, its a very comfortable ride.


Cafe Racer.

I think I may be done w these carbs.

I do not recommend you use these numbers for your own bike.  It could be way to lean and cause damage.  this is only a test.  Quite literally it may turn out to be a "trial by fire"  I am fully prepared to toss this machine into a dumpster and then throw the dumpster off a cliff and into a lake.

I got out of bed at 3am.  Went to the garage and rejetted these Keihins,  I believe this is my fix for this particular pair of carbs on my particular CB360.
I will know more after a test ride this evening.
I do not recommend these numbers for your own machine.

stock sized Keyster needles
jbm ind. diaphragms
floats at 21mm
Keyster pilots #35
Keihin primaries #55
Keihin secondaries #110  
According to the O2 sensor I have installed on my machine.  I have found after setting the air fuel mix to 12.5+ to 1 w the bike on its side stand.  Once I climb on and stand it up right, it drops to around 11.3 to 1.  If this O2 gauge can be trusted???

Waiting for the 55s

I am currently waiting for the 55s to arrive from jetsrus.com.  

So, I have been piddling around the house.

Freed these poor bastards from the dingy, fume filled environment of the Garage.  These sorry looking things are whats left of my Venus Flytraps after the 6 month winter storage.
I am amazed to see some green starting to show.
Got a bung welded on the right side pipe.  So I can swap O2 sensor and check the health of both carbs.
Went to ebay and found the front brake light switch I was needing.A good $12.31 spent.
I got it here... brake switch
Fits and functions perfectly.  
Best of all "free shipping"  and it got here fast.
Fried up Ribeyes on the Weber.
My little doggie sits and waits patiently for his.
