Happy New Year!! I haven't posted in a few weeks but have been busy working on the bike.

I got the parts back from the powdercoater and very happy. I also took the head to the machine shop and had him cut new exhaust seats, clean things up, and deck the mating surface. I also purchased 4 new old stock exhaust valves and got the rings gaped and installed on the pistons.

I cleaned up the fenders and removed the rust from underneath and coated them with an automotive under body coating. Got the rear light reinstalled as well as the turn signals. I also rebuilt the master brake cylinder and the front disc brake pad/piston area.

I cleaned the rims and hubs and laced them and partially trued them, installed new bearings, then took them to a shop and had them finish truing and install the tires. I also rebuilt the forks and did some polishing.

Hoping this weekend to get a roller up!! Just need to install the swingarm bushings and the steering bearings and start putting on pieces! I bought the rising sun tapered steering head bearings, I hope they are decent, kind of thinking I should have gone All Balls.

Thanks! It will be great for my home life too, I think the wife is getting tired of me being in the garage all the time!!! :-)

Spent most of the weekend working on the bike. Surprisingly, the swingarm bushings were easier than I had anticipated! Probably because I spent so much time researching that area. Things that actually tripped me up were a spacer I forgot to put back into the front axle and a boogered up lower triple bolt thread. Then, after having the front wheel off 2 times already, saw that I forgot the speedo seal!

It looks really great, keep at, but at a measured pace. Happy wife, happy life. Been there done that.

Thanks! Yeah hopefully now most of the grunt work is done. I met my self imposed deadline of achieving roller status by mid January, now to get it all assembled and ready for Spring!

Looks really good. My bike is in a similar state (400F), roller complete and engine ready to be rebuilt. I'm jealous of your progress. You're moving faster than me!

Thanks lol! I've been pushing myself pretty hard, as I am OCD and don't like the thought of an unfinished project laying in the garage in pieces, with so much invested! The sheer amount of time that I've spent on this blows my mind, this is my first full restoration and it is a lot more time consuming than I thought it would be.

On a side note, I have most of the engine work done, just have to rebuild oil pump and clutch, assemble top end and engine should be good to go! If you run into any issues along the way let me know, even though I'm fairly new to this, I may have recently experienced it too!

Not that I'm an expert, but be careful going too fast especially with the engine. I often find myself putting things together only to take them back apart because I missed a step.

Anyways, I have my roller totally buttoned up and ready to go, ready to accept the engine but the engine is totally apart, absolutely square one! haha. Need to push myself to get it done but I try to be careful and find a balance where I'm still having fun. I'm also kinda OCD, maybe even real OCD, but that also leads to stress from NOT working on it.

Yeah I was looking through your build, looks like you are going all out with your engine with the vapor blasting and case splitting, looks very nice!! My bike came 100% intact with 1 owner and 16k miles so I am hoping the bottom end is fine as it appears to be upon initial inspection.....fingers crossed! Engine wise, I just cleaned out the sump and did a top end with new pistons, had the mating surface decked, had new seats cut and new valves and stuff. Hoping that just rebuilding the oil pump and throwing in an all new oem clutch for good measure will get me where I want to be engine wise.

Very good advice about going slow, I have had to undo and redo my work on the frame and wheels a few times, so I really know what you mean!

jakec · « **Reply #87 on:** January 16, 2020, 09:19:03 AM »

Yeah, I'm not sure which post you read, but my crankcase had a hole in the bottom from another owner using longer bolts to install an engine guard. The bike did need some work but I was riding it around just with a huge oil leak. Eventually it wouldn't start up on day and I was like alright here we go. I'm sure yours is fine!

Was able to throw the tank, seat, and side kickstand on this weekend. Also spent a few hours sanding and painting the battery/air box with the undercoating paint that I used for underneath the fenders. The texture makes it look like there's rust or paint underneath, but believe me, it was nice and smooth before I shot it.

Focusing on electrical and handlebars this week......

Now, are you going to put the bottom end in and build out from there or install the engine fully assembled.

jakec · « **Reply #91 on:** January 20, 2020, 01:59:49 PM »

At first I was going to tip the bike onto the engine to install, but decided to put the bottom end in and build up from there. That's because I wanted to move ahead assembling the bike. If you're doing the tip over method it's better to leave most parts off to make the frame lighter and easier access (no blinkers in the way).

574hondarider · « **Reply #92 on:** January 21, 2020, 05:48:42 AM »

I was able to get the engine out while the bike was upright and tied down to my lift, with the help of my neighbor. Was thinking of building the entire engine and putting it in the same way it came out. I know I will have to take the brake pedal off, but I had to install it to get the rear wheel setup.

Mark1976 · « **Reply #93 on:** January 21, 2020, 09:42:12 AM »

Having done this, more than a few times and in various ways, its always been my preference to build it out on the bench and then install it. That way you can set the points, static time and set the valves at a more friendly work height. But I always drop the frame over the engine, its just sooo much easier, but I'm not young anymore either. You can do it either way, your build. (Regardless you'll need two people) Its also just easier building out on the bench, everything you'll need is right in front of you. Take your time, you'll do fine.

This weekend's progress:

Finished painting tank logos, installed tank logos, tank cap and latch and safety sticker and petcock.

Finished inspecting and re wrapping wiring harness, added atc style fuseblock, installed components into air filter box, installed air filter box on bike and insured ground up to coils.

Mounting coils tonight and this weekend hopefully will get handlebars, gauges, front brakes, and headlight wired up!!

--does anyone else get a small high off of opening new honda clear and white parts bags and installing new stuff on their bikes?!?! lol

A quick question about grounding issues after powdercoating: What places need powdercoating removed on this cb350f for grounds to work as intended? I have the main battery box ground, the engine mounts, and the holes for the bolts for the coils. Are there any other places that need a frame ground, such as anything up around the handlebars? I powdercoated the triple clamps, is this going to cause any grounding issues with the controls on the handlebars?

MauiK3 · « **Reply #96 on:** January 27, 2020, 08:48:27 AM »

I'm not familiar with the 350 but you will need to ground to clean metal any where a green wire bolts to the frame. Your turn signal and tail lights may have a local ground wire, check the wiring diagram for any ground symbols and see where they go.

carnivorous chicken · « **Reply #97 on:** January 28, 2020, 08:17:11 AM »

Front turn signals, which are grounded to the nuts inside the headlight bucket. I've had to route a ground wire past this for turn signals as there was a bad connection due to paint on the fork ears. And of course your main ground, which attaches to the frame near the battery. If I remember correctly, rear turn signals also ground to the frame but don't quote me on that one. Can have a look later.

574hondarider · « **Reply #98 on:** January 28, 2020, 10:13:08 AM »

Thanks guys. I was thinking about those headlight bucket nuts on the way to work today and wondering how the ground will be with the new paint and clear coats. I mounted up the coils last night and made sure to clean off a little bit of powdercoat from the bolt holes and add some electrical grease (at the time was going to scrape away enough powder coat for the entire square-ish coil mount bracket but didn't) and the coils show ground, but then I read somewhere where the 350s' coils get the ground from the points anyways, so I guess I did that for nothing. I am figuring it out as I go, just takes twice as long as it should!

So do the handlebars have any ground issues with a powder coated triple?

Tank work looks really nice.....

How did you install the gas cap? Meaning which pins did you use?
