Topic: 1973 CB350F Build

[ponishenko3136]

hey guys, this is my second build thread on here, i've done a cb750 cafe racer and had this 350f stand around for a long time and finally tackling it. building when i have time and money. im planning to go with a tracker/scrambler look on this one. i bought it with front and rear off a 2001 r1 that i was wanting to put on but think the rear end wont look so good going with the scrambler look. im thinkon go of swapping the front end though and keeping the cb350 laced wheel. are there wheel bearings that i can use that fit the cb350 hub but will take the r1 axle bolt? and will i need spacers or something for the r1 forks to work with this wheel? or do i have to buy a new hub from cognito? or should i just front and rear swap with the wheels and go for another look? i also have the parts to convert it to a 400, is it worth the hassle? what are some opinions? thanks guys

here is how i bought it, all torn apart and lots of work ahead

You can make an old honda hub fit a new front end, but unless you can machine parts yourself a cognito hub is probably cheaper.

You're going to be busy.  I can attest to that after three years on mine.

I have an assortment of parts I'd give to you for the cost of shipping.   There's a rear hub (situation with bearing retainer), rear rim, and miscellaneous other stuff...

Thank you, I’ll message if I run into something I might need. But I bought this bike with a ton of parts off it so should mostly be there

Thanks for the tip, definitely can’t machine that kinda stuff. Might end up going that route if unless I stay with the original front end

[ponishenko3136]

Thanks cal. It sounds like way too much work and money to go with the swap. I can’t machine stuff on my own and seems like just getting the front end swap will be a huge part of the budget. Might consider just doing the whole swap with the r1 wheels. Front and rear swap so wheels match. Or just go with the stock forks, swingarm and wheels.

Swapping front ends is pricey.  I think even machining parts myself I have $800 plus my time in the swap.  $250 for the forks, $550 for the custom rim and spokes + lacing, the steering stem and adapters were machined out of scrap bin material from my last job.  If you have to buy a hub and stem your probably looking at $1200 or so.

One thing to definitely keep in mind is going to the 17" r1 wheels will lower the bike and tire selection will be tough for those wheels.  Lacing to a 18" will give you height and options.

after deciding i don't want to spend that much money on just the front end im going with the original setup. found a triple tree on ebay so ill be putting it together to at least see how it sits and start planning the look. thanks for all the tips guys

I'm not sure I follow.  Tire choices for 17" wheels are MUCH more plentiful than for 18" wheels.

Sorry mean for scrambler off road tires

Lots of supermoto and adventure touring bikes use 17s.  I'm running shinko 705s which are a chunky looking 80/20 tire in 17s.

Not saying there aren’t options, but there are more with a wheel size outside of a 17

got around to putting the triple tree on, forks, swingarm, rear shocks and wheels to get a roller and start mock up of everything else

[ponishenko3136]

got the frame loop welded up and found an old rear fender/splash guard laying around and tried to see if i can do anything with it. i have it temporarily installed and seeing how it looks. it would need mounts on the side holes coming down from the frame to get more snug up against the frame hoop.
