Re: 1976 CB360t Slightly modified restore to roadworthiness - Beauty later project
No pics, but SUCCESS!!! I actually put 10 miles on her today. After a little work documented below.
A fully charged battery does help, but there was more.
I started Sophie up cold, and she ran fine. Warmed it up a little...still good. Though "Fine" does mean some burples and coughs.. I take her for a short ride, up a short hill and down (don't want to push her back, so start uphill first...LOL)
She seems fine, but on the way back starts misbehaving, so I pull her in the driveway where she quits running.. UGH.
O.K. the battery is low again????? Don't think so, but I get my booster battery (one of those external yellow plastic container ones) and try to restart. Bingo, restarts...must be a low battery. Get the voltmeter to check the new regulator.... 14.4 volts max, battery is 12.7 resting, gee, the battery isn't bad.
Think I have it fixed, maybe, and try to ride again...She stops. Won't restart.
O.K., maybe plugs, pull the plugs (New NGK Iridiums) and they are a little sooted up, but not fouled. Back in.
O.K., not battery, not Plugs, maybe Carbs? Maybe Timing? Maybe the points cover is shorting. I take off the cover, and there is no change. The cover wasn't shorting, and the right points look too tight.
I had timed the bike VERY well the last time, so I did not expect timing to be out.
I get my meter, my Alternator cover with a hole in it, and a strobe. Whoa, timing is way out....???
I can't get a handle on the timing issue. The left points are firing on the F mark, and the right are firing on the T mark...Check for shorts, cross connections...Finally disconnect point wiring from the harness..Seems all backwards.
I check the advancer for correct placement, but she ran fine, then quit...I decide just to start from scratch. The right points don't look like they are opening much at all, so a complete re-timing is in order.
I gap the left points, and set the timing to the "LF" mark after the intake valve closes. Perfect. Check the right, and the timing is a little advances, and the points are too shut. Adjust the right to the right timing, and the gap is about 0.014", perfect.
Now time for the Strobe. The timing is a little off. As I loosen the backing plate to zero in the left, the timing changes a LOT!!
Takes a lot of fiddling, but finally get the timing on the spot for left and right.
A few more checks, and I try a restart. Starts, but doesn't like idle. But is running on both cylinders and sounds better too. Idle is a little erratic, but throttle on and above idle, perfect....
Button her up, try for a restart....she starts.
O.K. Helmet, gloves and Jacket on, lets test ride.
Up the hill again, good. Back and forth, she is running nicely, except for the erratic idle. Pulls well.
My riding ventures further and further, finally was going back and forth a mile. My face is hurting from the smile...!!
Put 10 miles on her today. Except for the idle being a little erratic, she is running nice.
So,
1. PAMCO Pete, I need the pointless ignition .....
2. I need to work over the carbs again. I think the sync is off again, and I think the idle circuit is still a little flaky. I am going to clean them again, and re-sync. That should help with the idle.
3. I may need the throttle shaft seal repaired. I think the idle issue is a vacuum leak. The boots seem good (I may replace anyway), but the seals have never really been checked, and being felt, they are probably stiff and victims of age.
4. I need to clean my new rear rim, as the chain threw oil all over it!! Happy Problem.
5. Further Plans. A nice guy from Do The Ton, sent me a couple of tabs he cut off his bike. I need to replace a broken tab for the air cleaner mount. Once that is done, I am going to re-install the factory air box and filters. I am going to replace the paper element with Foam, but I think the factory box will help with the idle too, as the UNI pods may be causing some of the idle issues.
So,
I need to do a few more runs, before I trust her...Then I will start using her for local trips to the store and alike. Trust takes time to build.
Hopefully, the next run I'll have my son video some drive by's and you will be able to see and hear her rolling....
