cb 350 P2-light

well since I don’t think I can get my P1-500 championship winning bike back from Jody :laughing: I have to build another. I’ve never built a 350, and being a P2-light I can go a little crazy :mrgreen: frame started as a cb 360 and after lots of cutting, grinding and welding
[attachment=2]cb350-1x.jpg[/attachment] tank and seat fitted[attachment=1]cb350-3x.jpg[/attachment] engine mounts and extra frame mods[attachment=0]cb350-4x.jpg[/attachment]frame is almost complete

and more, frame is complete[attachment=1]cb350-5x.jpg[/attachment][attachment=2]cb350-6x.jpg[/attachment] the bike is rolling now, but I’m going to change the wheels[attachment=0]cb350-7x.jpg[/attachment]

lots of work to go, engine next, lots of go fast parts :imp: pistons, megacycle cam, valves, the works
:laughing: :laughing: :laughing: :laughing:[attachment=2]cb350-8x.jpg[/attachment][attachment=1]cb350-9x.jpg[/attachment][attachment=0]cb350-10x.jpg[/attachment] more project pics to come :smiley:

Alan, how am I suppose to drool over your bike with these tiny photos?

:sunglasses:

Wow, nice job. Can’t wait to see the finished product.

Really nice Alan! Looking forward to seeing and hearing it in a few short months… :smiley:

Scott

Very nice! Another quick CB350 that will kick my ass in P1500 :open_mouth: .

Hey Alan, hmmm… I shipped your P1500 down..you didn’t get?

Ok. So I finally get up to decent speed (without crashing!) in p4 and sure enjoy Jody wants to play in F3. So I start dusting off old 350 stuff, and now all these go fast bikes and guys jumping into p1 p2 350’s … I guess my podium day’s are over… NOT… look out you young whipper snappers, Grampa’s back!

With that said…what are the chances that p2 needs a rider for Barber next Fall ?? :wink:

Nice work on the build! I’m building a bike right now and would like to consider racing it along side you. Mine’s a CB 350 as well. 1970.

I looked at the rules but they seem a little obscure. What’s the rule with disc brakes if they didn’t come stock but from same period? I’d like to use the front fork from a cb750 (35mm) with front disc.

Also I got my frame welded yesterday but read that you can’t use additional frame support in VRAA. Yours looks like you chopped the hollow center support and replaced it with 2 side frame supports. Maybe I should do that instead?

So far I’m looking at

Bore tech 67.5mm pistons
X5 megacycle camshaft
32 mm mukuni’s
lightened/balanced crankshaft
cb750 forks
lightened 5.5mm valves with RD springs, titanium retainers and bronze guides
Head port/polish

As far as you know is there anything there that is non conforming?

I still need: connecting rods (no idea who is good)
Seat/tank
tires (not sure of allowable width. I think the cb350 actually came stock with wider tires than
VRRA supposedly allows too)

Any advice you can provide would be awesome. I’d really appreciate it.

I didn’t realize it was a 360 frame. Even more impressive!

still motoring along, rearsets, bellypan and wheels are the last big push. ready for trackday at Shanny

Allan

Very nice ride indeed.very nice workmanship.Are you going to pilot this bike yourself Allan.

Regards Paul

yes, I’m going to race this 350. Jody has first crack defending his P-1 500 title on my 500. I hope he says yes, it’ll probably be the only time I see a #1 plate on one of my bikes :laughing: If he has other plans, the 500 could be lent out again :wink: or sold :frowning:
Allan
#393

Hi Allan

Maybe with a friendly push he will defend the tittle.It would be nice to see the North Bay crew having the number #1 Plate up there again.Look forward to seeing the 350 at the Shanny.talk to you soon Allan.

Regards Paul

:smiley: wheel building on Good Friday :imp: :blush: :open_mouth:

the good and the bad, 1st the good, I got the bike done for shannonville track day yesterday. everything working as it should. brakes and suspension set-up right, super light and handled perfect. 2nd the bad,
after running the bike 2-3 heat cycles at low revs, i took the bike out on the track, 5-6 laps keeping the revs down between 6-8 grand the bike ran smooth, 2nd session more laps and more revs, staying under 10 grand. bike ran great, 3rd session, more laps and more revs. this motor should make power to 12, and everything seemed right, then 6th lap, opening it full down start/finish straight going into turn 1, poof :open_mouth:
black smoke out of the left pipe and power dropped off. oil pushed up through the breather into the catch.
broken ring? scored sleave? today i’ll do compression check and leak test. oh well that’s racing :smiley:

Nice bike! Too bad about the troubles.

Very Nice. Those pictures really make me wish I never sold My cb350 project, and would have stuck with it. I had a similar vision for mine, seeing yours all finished makes me really want another one…

If you want one that bad I have one collecting dust in my garage that I’m willing to sell. Full fairing so no belly pan needed. PM me if you are interested.
