Cb350, wider fender to fit a bigger Firestone tire?

I have a drum brake 72 cb350 and recently tried to fit a 4.00 Firestone tire but it hits my fender pretty bad.

Is there another fender that is wider? Such as a cl350/ 360 fender that mounts up? Or do I need to make a custom fender? I can't imagine I am the first person to have this issue, it would be nice if I could just bolt a new fender on.
 
Just take the fender off. With a 4 inch Firestone/Cocker, it won't actually be rideable much above walking pace, so you won't need a fender.
 
Since you can't ride a bike with Firestones it's a moot point what size you got. But you can usually re-drill the mount holes on a fender bracket to raise or lower it. Sometimes you can add another bracket to it to do the same using some metal, I use aluminum for something like that as it's easy to cut, shape and drill and it's light.
 
I think I will end this thread saying that a 18 inch cb360 disc brake fender I measured was wider width wise, not sure about vertical. Although isince it's a disc fender it has a extra aluminum bracket that must be used and altogether not really worth it.



I believe sourcing a 18 inch older drum cl360 fender would have more space for a larger the but not %100 still without measuring.
 
I really don't believe that the CB360 and CL360 fenders are different. The differences in the bikes are the gearing, handlebars, tank/seat, exhaust, and the frront brake.
 
Gearing isn't different. The rear fender is different between the CL and CB, though. CL had a higher rear fender. Regardless, does the rear tire fit the swingarm?

I'm guessing you are asking about a front fender. I have a 72 CL350 front fender and I will measure it later today. I'll even check to see if it will fit on a CL360 fork.
 
Yes front fender is the main concern, rear is a non issue. swingarm clearance is a non issue with a 4.00. Because my 72 drum 18in cb350 has a narrower fender between the mounts vs a cb360 18in i measured. The cb360 has "straight" fender braces compared to my cb350 which they were narrower and curved if that makes sense.
 
The CL350 front fender is 4 3/8" wide at the widest part of inside of the fender. At the narrowest part it is 3 1/8". It is a bolt on a 350 fork, 360 fork and even a CB750K fork. I suspect the narrow section of the fender is too narrow for a 400 x 18 tire but it does sit a bit higher than the CB fender due to the stock 19" front wheel on a CL350.

Yes it is. Stock front sprocket on the CB was a 16T, CL had a 15T. Internal gearing the same, though.

LOL. I'm talking about the transmission, not final drive ratios, especially when a countersprocket swap is as easy as a credit card swipe.

Yup. Subtle changes from year to year, but for the most part, engine wise, a 360 is a 360 is a 360. (Of course there IS the CJ oil pick-up and there were some late ones were 5 speed transmissions rather than 6, and there were the top oiling issues on the early models, and... and... and...) :cool: :):D
 
Here's an idea, I guess I should have bought the 3.50 firestones?
Here's a better idea. get some real tyres not some 1940 Harley tyres
I had some weird notion we were done with this about 10 years ago
You were not dumb enough to fit a 4" tyre on a stock rim?
The original rim is barely suitable for the 3.25" tyre fitted OEM
 
The CL350 fender is wider. I still had to trim the CL fender where it is indented between the fork brace and the fork slider. I was running a 110 18 tire on a wm3 rim on my race bike. It served my specific purpose on the race track to give me the feel I needed for my particular race compound tire. It was very heavy handling and I do not recommend it for the street or the track, for anybody but myself. The trimmed fender will probably clear the Firestone, but it would be better if you put a decent 90 or 100 width tire on there.
