Well, this weekend I picked up a 1972 cb350. I got her on the cheaps, so I'm pretty excited. As you may have noticed, I have been polluting the 'other bikes' section here on the boards because my 750 has been running great! So, basically I was wondering what I should do before I think about taking her on the road? Aside from the obvious- tires, fresh oil, carb clean, plugs, blow out air cleaners... I have some rust and I will be stripping the tank & painting. Battery blew up, so there is a neat little splatter that rusted. I have two other stock bikes, so I want a neat little cafe-ish bike- but I want it to RUN GREAT well before I get into modifying anything else.

Any thoughts?

Clean out the centrifugal oil filter on the RH side of the crank, cant remember wether its got an acess cover or you have to take the clutch cover off---either way DO IT

There is an access cover. Best way to get it off? Impact driver?

Ha! Yeah, a buddy of mine who races a 69 Chevelle was trying to convince me to let him go to town on rigging up a turbo on my 750. If you do actually do it I will enjoy reading how it goes

My oh my! That was a pain to get off, but there was a ton of crud in there. I'm definitely glad I did that.

Well, now I've been getting into it- probably distracting myself from the work that needs to happen on the other 350.

-Chain has been cleaned and lubed
-Oil filter cleaned & new oil
-Carbs are off and are cleaned
-Air filers have been replaced
-Rubber is good
-New plugs
-Points cleaned
-New Fuel Lines & filters

I haven't put the carbs back on, but before I took them off and after I got the proper filters on with decent boots the bike would ride well and then hit a wall. It would not keep accelerating unless I shifted. Before I put on the other air filters the bike would acell just fine, but it had a wicked idle. The filters helped the idle, but now I've run into this. Hopefully, I the carb clean will help this. there wasn't anything gummed up. I just cleaned all the passages and cleaned the bodies. I'm not sure what it could be. Might be a timing issue?

mikedialect · « **Reply #6 on:** June 20, 2007, 03:26:57 PM »

Cleaned the points again (ordered a new set too) and it's running like a champ!

I did go and put flat bars on it, but I ran into an issue with the wiring. I was unaware that the controls ran through the bars. It was a pain to get all of that out... Now I rigged it up to work, but the throttle is a little messy now. Best way to deal with that would be to drill the bars? There really isnt another way that I can think of...

mikedialect · « **Reply #7 on:** June 20, 2007, 08:37:21 PM »

Well, I drilled the bars- not my best work, but it will do. Now I have cause yet another issue, or I should say I have stumbled up a learning situation...

I screwed up the starter button. It came apart in my hands... I was wondering if anyone had any experience in relocating the starter button. From what i can tell there is only one wire. This is correct? The question then is this: What type of switch do i get for this? Anyone have any suggestions on what to grab or if I'm missing something here?

1. Strip it of anything unwanted/needed
2. Lower the hell outta it
3. Throw some clip-on bars on it
4. Ride the hell outta it..

dr.proteal55 - I sent you a message in regards to the starter issue. If you get a second- please check your personal messages!

got it! Thanks!

The starter button is available from Honda. As you say, only one wire goes to it; it grounds the wire to the handlebar.

I saw that, but it is an assembly issue. So, as I understand it (proteal's tip) I can wire a momentary switch in another location. I assume the other prong on the switch would be the ground?

I'm such an amateur when it comes to so much of this stuff! Many thanks to those who have helped so far!!

U are correct sir..

Like I said I got the little push switches from Home Depot for under $5 each..

If everyone followed some of the advice given here, all the bikes would look the same. $:-\$ Perhaps that's why some folks look around, see what others have done and use ideas of their own along with some ideas others have used. If you do relocate the starter button, I'm hoping that you'll pick a spot that the switch can't accidentally be activated.

There are a lot of folks here who have built some great bikes and if you'll notice, most have their own distinctive look and features.

Later on, Bill

Agreed! I took the simple knowledge and I am trying to put it to my own creative devices. Not sure how it will come out, but I think it will at least work!

mikedialect · « **Reply #16 on:** June 24, 2007, 07:40:03 PM »

Electric starter works, but now I believe I have a gasket leak on the bike. I went for a ride tonight and when I pulled into the garage I was smoking and leaking oil from the top of the engine. Now I have 3 bikes that aren't running! Isn't that just inspiring! I think it's about time to go buy a ducati and mortgage the roommate.

Now there's a thought!

Nothing running can be depressing, hope things turn around for you soon.

If only the bank liked me more

I guess I'm going to have to chase this leak down...

mikedialect · « **Reply #19 on:** June 26, 2007, 06:19:31 PM »

Well, I found the leak....

I have oil coming out of the Tach cable!?! I rode it around for a bit tonight, just to get her warmed up to see if I could ind the culprit. I pull into the garage and let her idle for a bit and I'm searching high and low because she hasn't totally started smoking yet and I see some bubbling right where the tach cable goes into its housing. I pull the cable and sure enough it's coming from there! This would explain the very specific drip pattern on the motor.

Now, why and the hell would that be the source? What's the fix on that one!?!

mikedialect · « **Reply #20 on:** June 27, 2007, 01:08:48 PM »

Well, I've looked for a 'how to remove tach housing gear' everywhere, but I can't seem to find anything. Does that spinning gear NOT come out without removing the whole tach cover?

dusterdude · « **Reply #21 on:** June 27, 2007, 01:29:33 PM »

just a guess here,if the cable is held in by a screw,remove the screw and the cable will come out,now take a pick type tool and reach in there and remove the seal,by a new seal and install.

A pick type tool, eh... I hadn't thought of stabbing the damn thing! I suppose it's not worth much as it stands! Thanks for the hint. Hondaman suggested a crochet hook, but I'm as single as they coming and I never quite picked up the hobby;)
