Save it for MOPAR, punk. ;D

but you just dont see h or crossovers on twins with 180 cranks it has to do with the spacing and timing of the exhaust pulses and reversion effect there is a lot 2 it
180 twins do better with individual pipes all the way back
it could actually cause more "resrtiction" i think if it was advantagouis then it would have been done at one time or another by a oem mfg but you only see it on triumps bsa's and other twins with a 360 crank
i am all for experimenting but i just think on this one yer barking up the wrong tree

I would agree that it would be of more benefit on a 360° twin. If I have the time and money, I would opt for a two into one setup with unequal header lengths.

Looks like we got the same forecast, bubba! champaign illinois here. So, you must be kinda close.
lol you must be pretty new to 360s. These things got a lot of personality. But I wouldnt have it any other way ;-)

Yeah Im new to classic/vintage bikes in general. Im just ouside Purdue University, West Lafayette. I often take trips to the Danville VA Hospital, so yeah im in Illinois quite a bit. :)
 
Re: 76 CB360, making ready for checking carbs.

My local pure gas source has dried up. So, now I got drive 50 miles to get it. DANG.
Gonna have to get a 2nd 5 gal can So I can keep 10 gallons at the house at all times.

Also, gonna check w Don and see if I can buy a 30 gallon drum through him. And keep that at the house. That should keep me pretty well stocked throughout the summer.

If your hunting pure fuel, without alcohol or ethanol. Heres a great resource.

Re: 76 CB360, Lovin the new pipes.

Temp hit 41f today. Got bundled up and took her out for a ride. 2x10 mile jaunts. I swapped the o2 sensor to other pipe 1/2 way. I considered running her out to Bromz place. His bike is torn down in my garage and he sold his 360. So, I know hes getting the bug now. ;)

;D Lovin the new mufflers. They Are less than 1/2 as loud w a way deeper tone. At 6000 rpm they hit a really low note, growling kinda rumble. And under WOT they really come to life at 7000rpm gaining acceleration quicker. Its not like Im having to hang on for dear life. But, it does kinda take off...best as a 360 can. LOL ;)

She is running superb under 4k. At 5k she gets a bit rich. Running approx 11.5 to 1 ratio. So, I will have to look back. But, I think I have 112s installed and gonna take her down to 110s and that should be the only change.

LOL, Other than Pjs mods and my own soldered Primary emulsion tubes. The jetting will be pretty much right back to stock.

After a long winter, now soaked in salt and road grime...just the way I like her best.

The Hagons are great also.

A rare Cafe racer... not only looks nice, but can be, and is, ridden.

I think you may have a market for those sexy pipes too

thanks bubba. I think I may be racking up more miles than ever, this summer. I like that I could actually hear myself thinking during the ride! :D
 
Re: 76 CB360, Lovin the new pipes.

Where better to spend a monday evening?

Digging into the "rich above 5k" issue.

I do believe im armed and ready.

Re: 76 CB360, Lovin the new pipes.

i was just noticing the location of the coils,it does impede-atate cooling airflow thru the head a bit ....seems some small side scoops are in order to direct air and could be an interesting adition to the theme 8)

Thanks bubba, When I did install the coils up front. I used the non-contact thermometer a lot. Hell for a short while there, carried in my jacket pocket. Mostly to insure coils werent getting cooked by the pipes. And I was delighted to find the backsides of the coils nearest the pipes never got over 100f degrees. I still check temp of the headers nearest the collars, often. Just to make sure I dont have an unexpected lean carb. (I only use the o2 sensor for troubleshooting tool, its not permanently mounted.) As with the head nearest the spark plugs. Less often if header temps are within normal average range. Im sure there is a bit of a flow change. But havent "noticed" anything major.
but still a scoop is not a bad idea.
 
Re: 76 CB360, Jetting.

Tonight Im gonna crack open the carbs.
After giving it some thought.
Upon initial start up, she was real lean at the idle. I had to give A/F mix a couple turns out.
Changing pilots from 35 to 41
Going a bit too rich 11.5 to 1 at 5k+ WOT. I would like to see 13+ to 1
changing the secondaries from 112 down to 107

Wasnt so rich as to pop and sputter. riding temp was 41 and once its summer it will be just that much richer

Engine cold or warm?

Upon initial startup. I gave some turns on the idle, to keep her running, til she warmed up "enough" then put the o2 sensor on her. She was pretty warmed up by that time. But after the excitement. I let her get good and warm and tuned the A/F w sensor. She dialed down to 12.8-13.3 (fastest idle) to 1 but them needles are about to fall out. Not really. But they are out there! RPM is set to 1200 also. I was toying w the 41 idea last fall. just for fun. So, thinking "what the hell" worth a try, now. And let me crank them back in some.

Kinda like an experimental aircraft.
 
Re: 76 CB360, Lovin the new pipes.

On the front page this thing was dressed like a two wheeled dominatrix... with a fuagostone on front haha wtf man!

Those megas are sweet though!
 
Re: 76 CB360, Lovin the new pipes.

Don't worry too much about A/F ratios until the bike is warmed up. Even modern EFI systems ignore the O2 sensor until the car's been running a while.

HA thanks dude. Yeah I ran those P.O.S. firestones for 2 years. The $200 cost and outrageously cool look of those things made it hard to justify moving on to something different.

The bike was scary on long mild curves at 50mph. Then, signed up for the first year Spring Thaw in Kentucky.

Thank god I bit the bullet threw them in the dumpster and found out what a real set of tires feels like. Best $200 I ever threw away.

Had I even survived the twisty Kentucky roads on the Firestones, they would have completely ruined the trip.

I swear the secret ingredient in the AVONs is asphalt glue.

I got a comparison pic of the avons and firestones side by side. its easy to see the difference in the square firestones. you have to try to balance the bike on the edge of the tire when leaning around curves. The contact patch is zero.
