Had a friend get me the throttle stop screw setting. I had mine very close to his, so leaving alone for the moment.

Checked the lash adjuster shim adjustment as well. Changed number 2 intake to "0" shim(s). Turned engine over cold, "0" compression. Started the engine and let warm up, still no compression. Installed one intake shim and compression was good - didn't have to touch the exhaust shim adjustment. With no shim, the intake valve must have been held open just a bit. Monitoring as usual.

Have a few Kms on the engine now, and quite pleased. I will be parking the bike on the side stand and keeping track of the first startup in the morning for blue smoke. As I have mentioned, shouldn't be any with a fresh engine rebuild, and new rings.

Will just ride for the time being. When I get to some 7K Kms and time for an oil change, will check compression at that time. Need to let everything settle out. Not concerned with a break in period. Research indicated that should be able to put everything back together and go, no need to do any fancy so much of this, then this type stuff.

In the meantime, will ride it like I stole it. Going to miss having something to do, but not to worry, I have a lot of other things to do.

24 hours on the side stand and no smoke on startup. Supposed to be miserable weather for the next few days. Intend to change out the #2 cylinder injector back to the OEM. Working on the fuel system is not one of my favourite pass times, takes a few days for the fuel smell to be gone.

This is going to be a very boring winter season. My projects are at a stage where I don't have to do any work if I don't want to - I get to pick and choose when to work in the coldish garage. The 1200 is a ride it like I stole it bike now - minor cosmetic items to tidy up. Heated clothing is the rig of the day.

Looking into what we need to do for our cross Canada trip next year. Pull out the trailer, make sure it is clean and the gear inside it is in good nick.

More time to exercise, it's good for me, but takes a lot of discipline.

Monitoring the engine performance regarding the new rings. Have to get some Kms on it before another compression test is done.

Thought I'd make a post to let the collective know I'm still alive and kicking, and still browsing.

Cheers

It's been about three weeks since I stated the 1200. Been on the side stand all this time. Decided to start the engine, let it warm up and see if what I have done is good. Satrt up was good, a bit of smoke, really had to look to notice, out the back end, but I think more from just sitting and whatever is in between the rings, and such. Pleased with the start.

There is still an unburnt fuel smell on start. Been thinking about this, and the IAC system is a key element in getting enough air into the cylinders when the throttle is closed, allows air to pass by the throttle plates. This is needed because the throttle plates close completely at idle. There is no fast idle cam to keep the plates open at cold start, or when riding.

Know the reed valves are working, but the air passages in the throttle bodies could be restricted/partially blocked. Thinking this would be a good project, remove air chamber and soak/clean/blow through the air passages. January/February would be a good time frame. Replace the small vacuum hoses on the reed valves - have replaced the larger ones.

Another two weeks or so and had to move the 1200/Spyder for work and such. Pleased to report that when the 1200 started, no blue smoke. The new rings are working well.

Have the unburnt fuel smell that I am surmising is a lack of combustion air. Will be looking into this soon.
