Salzburg '73 CB350 - Summer Riding Update

Re: Salzburg '73 CB350 - Update: Motor runs! -- Pin hole fuel leak :(

Sucks about pin-hole but better to find it now than have a tank of gas dripping on hot engine
That just reminded me of a GSX250 I worked on years ago,friend noticed paint bubbling on seam and before I could stop him he rubbed it which pushed the rust and caused massive leak ::)
Probably wouldn't have been so bad if it wasn't a traffic cops bike that he needed to get to work that day
Everything worked out eventually though

Sealing the tank this afternoon.... I hope it fixes the leak. I'm getting anxious to ride it.

99.99% finished by Matthias Salzburg, on Flickr

Loaded up the bike on my truck hauler. I'll take it to my local shop for state safety inspection and then go have the carbs dyno tuned. The seat pad and front fender are yet to be installed. I'm still waiting on my fork brace and have the stock 450 brace on it temporarily.

The VW Bug is a 1970.
 
Re: Salzburg '73 CB350 - Update: 99.9% finished / tank fixed / state inspection next

Bike looks great! Hopefully the inspection goes well and you can get out on the road. I really need to get back to working on the one sitting on my work bench. I've been spending all my time riding the other bikes haha.





As for the Bug, I assume a 70 body on a pre 67 chassis.

Nope, 70 on a 70. Brakes are CNC 4 pot (Baja racing stuff) wide 5 bolt pattern. All other aftermarket brakes are shit. These can lock up the wheels on dry pavement and have great pedal feel.

2442cc, TF-1 aluminum case, twin Weber 48 IDFs, Berg 5 speed with a ZF limited slip diff. Hauls ass.

Whoa...wait. You are in Missouri? What part? I'm in the KC area.

Bike looks amazing by the way!
 
Re: Salzburg '73 CB350 - Update: 99.9% finished / tank fixed / state inspection next

The bike passed safety inspection today. :D

I'll get it on the dyno tomorrow.
 
Re: Salzburg '73 CB350 - Update: 99.9% finished / dyno / state inspection passed!

Lookin forward to see the dyno results.

Also, just went through the build and that techflex wiring harness sheathing really looks clean.

looks good my man! can't believe how close it is to mine... same tank, same tail, gold chain, same muffler, similar rearsets, header build looks identical!
 
Re: Salzburg '73 CB350 - Update: 99.9% finished / dyno / state inspection passed!

Just got a call from the dyno shop. It's running a bit rich in spots and lean in others. I jetted it with recommendations from other builders. He's going to try some things to get it running smoother. Hopefully I'll get it back today or tomorrow.
 
Re: Salzburg '73 CB350 - Update: back home - needs front fender work

I picked it up from the shop today. I rode it home and she died on me 12 miles from the shop. Apparently my gas cap isn't venting properly. I had to crack it open for it to continue to run.

Also I need to raise the idle speed a hair. I had to keep goosing the throttle at stop lights or she would die.

What do typical 350s make at the rear wheel? Mine seems a bit low considering a complete fresh rebuild. 23 hp at 9000 on a DYNOmite machine. Don't most make 25? I know Honda claimed over 30, but I think those were done under the older SAE H.P. formula. Also that might have been crank H.P. and not RWHP. Seemed like most plots I saw online from others were at 25?

There needs to be a thread on this! ;D
 
Re: Salzburg '73 CB350 - Update: back home - needs front fender work

Should be making 28~30bhp, that's well down so something isn't set up right
Honda claimed 36bhp but that was at the crank
 
Re: Salzburg '73 CB350 - Update: back home - needs front fender work

Could it be timing or fuel? The shop owner said he re-timed it, which seemed odd since I set the timing according to the Honda shop manual with my timing light.
I'll check compression as well with my tester.

Advancer is working and full advance does line up around 3,000rpm?

Aluminum fender bracket by Matthias Salzburg, on Flickr

Got started on mounting my front fender. I'm ditching the stock fender bracket (replaced with Tarozzi fork brace) and am fabricating some aluminum brackets. I'll also use some small tubing for front and rear stays to help brace the fender.

I've yet to mess with the engine idle or check timing advance.
