The right side is still much louder than the left, and I think I've figured out why! Back in 2013, when I first started work on it, I had to file on the right side head and block both to get them flat. I don't know how much I removed but it may have been as much as 5 thou (total). Could this have increased the compression on that side? I know that my compression testing a while back showed #1 to be 20 psi higher than the other cylinders.

My gleanings from the learned folks her is 0.005 is not much but could bump it a little and also retard timing on that side, but not much.
Whatever I suggest here should be given ample time for a moderator to delicately correct. I apologize in advance.

Loaded up the Hunley and took it to Stearns, Kentucky to the Moonshiner's Run Car Show. Had a great time, met some wonderful folks, and talked to a lot of them about the Hunley. Next up is new lower brake lines and new tires, so I can get some riding in this fall!

Well, the wheels and new tires are on and the new lower brake lines also. Bleeding the front brakes I noticed fluid on the plastic that I had put over the shelter (glad I did). Coming from the master cylinder around the push rod. Went ahead and ordered a new China el-cheapo and it is on the slow boat (uh, I mean China Post). So, with things a bit on hold and monsoons rolling through the rain forests of East Tennessee, I decided to check on engine things. Ohmed plug wires #1 to #2 is 25.2 kOhms and #3 to #4 is 25.8 kOhms. # 2 plug looks awful - I don't see how it could fire there is so much wet black (gas smelling) on it.

I then did a (cold) compression test which was really confusing.

Remember now, #1 and 3 cylinders had been discovered with bad rust that I scraped off with razor blades. #2 and 4 looked fairly good. #1 and 3 first compression tests were bad and #2 and 4 were Ok. Well, NOW #1 and 3 are 180 psi! BUT!!!! #2 and 4 are down to 120!!!???

So, I am suspecting (hoping) that I've missed a tooth on the left cam belt. Would explain a lot of things like fuel economy, difficulty in getting it timed, difficulty in balancing carbs. Oh, replaced the carb 2-4 balance screw today as the old one seemed maybe stripped.

So, left belt cover comes off tomorrow and (hopefully) correct that issue, then redo static time, valve lash, fire it up and do strobe timing followed by carb balance. Don't mind that work - a lot better than thinking about one bank running 60 psi lower than the other.

Left belt was off by one tooth!

Post #97 by pidjones » Fri Aug 03, 2018 1:42 pm

Well, I'm happy. dancr Removed the left belt cover (ratchet head wrenches are a blessing) and indeed the belt was off by one tooth. Corrected that and readjusted left side valves. #2 and #4 compression is now 155 and 175 psi! After a bite of lunch (wife is cooking catfish), I will reset static time, put the clear timing hole plug in, and take her outside for strobe timing and carb re-balancing. Woho! Maybe she will be too loud out both sides now!

We have much better idle and throttle response now. Retimed (static - checked with strobe and was spot-on) and balanced carbs. Made some spools out of some scrap aluminum slugs I had and tried out the Harbor Freight stand I'd picked up a few months ago. Makes it muck nicer for working on. The spools are mounted to longer lower shock bolts. I have allen heads on order that I'll counter sink into the spools.

Working on the CB750F project today. Changed the oil before doing a compression test. I sure hope that I am never this kind of P.O.:

The first oil change I did on my Gl I discovered the po had left the spring out, no where to be found. I started double checking everything he had touched.

After finding internal snap rings in the external grooves in both the front and rear of the Hunley's driveshaft, I shouldn't be surprised. On this one, they had a sheet metal screw jammed into the tach drive housing instead of the 5mm X 20 mm bolt that belongs there. The screw split the housing, but I think that I have it JB Weld repaired. Not worried about the appearance as this is a rat bike build anyway. The front forks had been replaced with forks from another bike (750 series I think, but not sure - has a leading axle). Has welded-up (not painted however) adapters to hold the old CB750F brake calipers that are frozen solid.

Well, . . . . the 750 front forks turn out to be Kawasaki KZ750H, and because of the leading axle (and being mounted in the CB750F triples) gives a trail of only ~3.2" with forks extended and 2.3" with them compressed. Just too little for comfort, so I'm pulling them off and replacing the whole front end with '78 GL1000 forks and triples. I had the forks left over from the Hunley build, so just need to put the new seals in them and get some triples (all over eBay). Won't need the cruddy steering stabilizer that they had welded on it then. The brakes are already identical to '78-79 GL1000. Cleaning the carbs on it is pretty easy compared to the Hunley as it was last fueled with non-alcohol fuel and just has rust from the tank and varnish in them.

But that will all wait for a week because we are headed for Barber this coming week for vintage weekend and the museum.

Hunley update time. She's been resting quietly in the "family room" side of the basement for over a month. Today I backed her outside, fired her up and turned off the petcock to run as much fuel as possible out of the system. When she finally died, disconnected all fuel lines and drained the float bowls. Topped of the tank with treated, real 100% gasoline. After airing out a while, rolled her into the garage and removed the carbs for a winter servicing. She'll go back into the family room tomorrow.
