It's ALIVE!!!! Running in suggestions?
- Thread starter tma360
- Start date
Compression check will have to wait until tomorrow, but "a bunch" means one of my neighbors came down the alley to make sure someone's house wasn't burning down... granted I live in a pretty yuppie neighborhood, but that's still pretty bad!
I started it a few times with no smoke, or no noticeable smoke, then it slowly began to get worse. I am pretty confident the rings are in the right way round and there are new valve seals, so perhaps it is the valve guide? Although since it didn't happen right away, I figure they can't have fouled in the five minutes I was running it.
Beside the smoke, which I am probably just overreacting about, any running in suggestions?

That's a can of worms right there.
My advice is progressive loading over the course of the first 20 miles or so. Let it idle to warm up and dial in the timing, sync the carbs, set air/fuel screws, and adjust the idle speed. Bike should be warmed up and ready for the first ride.
Take it up and down the street a few times, keeping it in first and second. Try to stay off the brakes and let the engine do the braking for you. Keep the revs at or below 4000 rpm, but never steady.
Then find a country road with very little traffic and start the break in. A full throttle run through the first few gears, but short shift it about half-way through the rev range. After you hit your artificial redline, coast down to 3000 rpm, then downshift through the gears until you come to a stop (or near stop without killing the bike). Repeat again and again, adding 1000 revs to your redline each time, and 500 to your downshift point. Continue until you reach about 1000 revs short of the bike's redline. This will often be five or six total runs.
During this process, be very sure not to lug the bike. Better to rev a bit high than to do something like shifting into 5th when you're only going 20 mph.

thanks Sonreir. Is it better to run a little rich at this time? We pulled or plugs and we a running a little rich.Sonreir said:That's a can of worms right there.

thank you we will go down a set of jets. We are at 105 and will go down to 102. Starts without a choke but on the maiden voyage to show our neighbors who helped us she was a little hard starting after being warmed up and shut down. How long should we wait before doing a compression check? We have a small amount smoke at this time.Sonreir said:

yes it was dry. We shot oil into the cylinders and it jumped to 180 plus.Maritime said:
Just did a check and have 120 on the left and 60 on the right. Gonna shoot some oil and see if it changes...I am pretty sure the valves need to be adjusted...the oil didn't circulate till we fired it up for the first time. I have a pop sound every 4 seconds.
