Good Morning!

I'm working on building a CB350 "chopper," but its really a '72 CB350 with mix and match parts, and extended front fork tubes/big handlebars.
Just got the frame back from being powder coated- picture for attention!

Anyway, I have to sort out what front end I want to put on this thing now. I'd like a nice clean look that won't require rubber gators. I have what I believe to be a CB175 front end in stock. Is there any reason I shouldn't use this? I'm used to my CB750, and my other 350 scrambler has a pretty rough suspension (for my tastes) as a 6'5" 240 pound middle aged guy. So my gut tells me I should go with something better. The only fly in the ointment is that I powdercoated a CB350 triple tree, that needs the threaded top cap to hold the fork tubes in.

Am I wrong? Is this an SL350 front end? Because if so...I guess my problem is already solved.

So I guess I'm looking for any feedback on this from you guys. If I use a CB350 front end with external springs, will I be able to set it up like this link? Or is that unsafe?


I guess the first question is, what is this front end? Its got 33mm fork tubes on it. Is it an SL350 or 175?


Thanks guys! Looking forward to the feedback...

I have no idea what those forks came off, but that aluminum fork brace looks like it might be an aftermarket addition. The 3H stamped into the front of the brace may be a clue — are there other markings?

The upper portion of the forks, where the cap bolts go in, does not seem to fit SL350.
 
Easy answer (as a spectator) would be to install it and if it handles funny then that's your answer.

What is the bike going to be used for?

I have a 350 w extended 33mm dia forks and brace. When I carry a passenger, we're over 240lbs and no safety or handling issues.

As a side note, there are lots of 35mm cb450 and 750 extended forks out there and I generally pref the 35mm tubes over the 33mm tubes... but like mentioned above, no issues w my 33mm tube setup.

Unfortunately, no other markings, but definitely aftermarket. I am supposing it came from a mail order company for guys making semi-choppers like I am doing now...

This is great information...I should seriously consider a CB750 set up I suppose, as I am generally familiar having rebuilt mine.

The bike will be used for tinkering mainly, but general evening cruises around the outskirts of town, and I guess an occasional bike night. Just really for fun you know? Not planning to have any passengers on this one. Any pictures of your 350 front forks? Are they the external spring model forks?
