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.

Could be, these motors have high compression to begin with, When I did my gaskets and tested after, the bike had the high side of factory spec and it has 200K+ miles on it, so I bet you could have increased it.

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!

Back on the furniture dolly. Wheels are at Honda of Knoxville for mounting the new Duro 918s. I know Shinkos are popular for this, but I had bad blistering on my GL1800 with them.

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.

Check valves on that side too, may have gotten tighter.

Well, I'm happy. :) 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!

Woot there you go. Good luck with the time and sync, should run much better after that.

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.

Bled the front brakes still again, and have a pretty good lever now. Pulled the lift spools I had made off and counter-bored them for the new grade 12 (all that was available) Allen head bolts and washers and re-installed. Now I can pick it up easily with my spool lift. Makes work on it much easier, and storing it on the stand keeps it upright so the left bank doesn't fog the neighborhood on startup (I had ground off the center stand).
