Re: 72 CB350 work in progress

Nice going scud. Beside the engine issue, the bike looks to be in great shape. Are you just planning on completing the engine work, or will you be doing some other things while apart?

lots of little things for the looks...stuff like bars, cables, bolt-ons, polishing & painting, grinding some tabs. I'm going to try to make a cafe inspired seat with my stocker that will still allow me to have a passenger too.

 

Re: 72 CB350 work in progress

Ouch that bike looks way too good to chop up.

 

Re: 72 CB350 work in progress

I was thinking the same...When I obtain bikes that clean I leave them stock. there are just too many roached junkers out there to be had for next to nothing that make great platforms for customizing to your hearts content that the thought of hacking on a clean original one kinda hurts.

but of course it's not my bike and we'll happily follow along with progress either way.

 

Re: 72 CB350 work in progress

yeah, to each is own, that's for sure!

I wish there were more junkers out this way. Hondas like these are few and far between here. I see bikes like these that are barely running selling for $1,200 - $1,500 all day long in SoCal...ridiculous...

I'm a young guy...and although I appreciate the beauty of a restored vintage CB...it just doesn't fit my style. So I must hack, chop, and grind my way through...but I do it with love

 

Re: 72 CB350 work in progress

go for it!

 

Re: 72 CB350 work in progress

Yup, your bike, have at it and enjoy the build. Similar around here, not many of these bikes at all. Very rare to see any Japanese twin for sale locally, I was very lucky to find my 350.

 

Re: 72 CB350 work in progress

I really like your 350 Perry...been impressed with it since I first started snooping on this site. I just looked over your 400 build you did awhile back. I hoping to have that much persistence to see this build all the way through without cutting corners!

 

Re: 72 CB350 work in progress

Be hard to cut on that one,but as long as you ride it,it dont matter.

this thing is going to be a daily driver...so I'm going to ride the poo out of it :lol:

 

Re: 72 CB350 work in progress

cleaned up the lower cases some today so that I can drop them off tomorrow for soda blasting.

question: do I need to remove this seal from the case? if so, how should I go about doing it? my first thought was tapping or prying a little with a flat head...but that seemed to likely to damage it...

 

Re: 72 CB350 work in progress

If you're spliting the cases you should replace all the seals while your in there. They have probably hardened up over the past 40-years and will eventually leak.

To remove the seal you can tap it out from behind, if your lucky enough to have access, or use a flat tip screw driver to lever it out from the front. Go easy and move from side to side as you go.

A lot of these seals are still available from the Honda dealer and usually for less then they are being offered for on e-bay. You can also take your old seal to an industrial bearing supply shop. On the front of the seal you will see three numbers. Those numbers corrispond with the thickness, inside width and outside width (Though I can never remember what order). Using those numbers a bearing shop can usually find the seal you need in stock.

Good luck with the build.

 

Re: 72 CB350 work in progress

Thanks 74shovel...I realized after I posted that this seal will be in the engine seals kit I'm getting from bore-tech...I just spaced for a minute because I'm so focused on not damaging parts I need to reuse!

 

Re: 72 CB350 work in progress

lower cases came back from soda blast today...looking very nice now. top end should be done at machine shop next week...should have my gasket and seal kits by then to start the reassembly. mufflers came last night and were supposed to have a satin powdercoated finish, but it looked about as thick as a two-coat rattle can job :shock: and there were places around the stabilizer arm bolts where it was flaking off...unacceptable. already emailed seller and they will be taking them back. so now I'm back on the hunt for mufflers...but it just doesn't seem like there are many options for these 350s. I've seen the megaphones and cones and shortys...all chromed. If I have to settle for chrome than so be it...but I would like to find mufflers that resemble the MAC 4-1 (black) on the 750s, but just shorter. I like the idea of having a muffler in the 12" to 16" range. so the search continues...

 

Re: 72 CB350 work in progress

lets see some pics of those sparkly clean cases!

 

Re: 72 CB350 work in progress

ask and you shall receive!

 

Re: 72 CB350 work in progress

nice!!! they look great !!
so what are your plans ... paint the cases? clear coat the cases?

 

Re: 72 CB350 work in progress

gonna go the paint route. got some engine enamel coming from jegs. I got nu-cast aluminum for the lower cases, going to do the cam housing and breather cap in that too. then I have black for the cylinders. then a good polishing on the side covers before it all goes back together!

 

Re: 72 CB350 work in progress

If all you are looking for is a satin black finish for the mufflers you can order a set of after market chrome ones, scuff them with course steel wool, then paint them with VHT high temp satin black. They can easily and inexpensively be touched up if the paint gets chipped.

yeah, that's what I figured would be the ultimate outcome. I'll keep on the hunt...but if nothing turns up, I'll go for the scuff and paint method!

 

Re: 72 CB350 work in progress

started work on my seat today. trimmed down my stock pan so I can make the profile lower. I was going to leave a little cafe-inspired hump in the back, but have decided to make it straight-ish, with a little curve following the natural bend in the pan. it won't be as dramatic of a bend, because I will trim the foam so the seat has as flat as a surface as possible. I will be using my original pan, foam, and cover.

 

Re: 72 CB350 work in progress

not to burst your bubble or anything but most of the strength of the seat was from that lip that you cut off. without it you are mostly left with a thin metal sheet
without the lip your seat will bend over time

yup, I noticed the thinness of it. going to do some reinforced welding to not only close up the gaps but also to provide support. thanks for heads up just in case!

 

Re: 72 CB350 work in progress

top end back from the machine shop. now the extensive cleaning begins in preparation for paint!

 

Re: 72 CB350 work in progress

parts look great!! can you post a shot of the machining that they had to do fro the KA slipper for the forum to see
