It's Alive! yahoo

I was finally able to carve out some time to work on the FJ and finish installing the new cylinder and pistons .
The rings were a bitch to deal with due to the small taper left after you bore out a 1100 cyl to 1200 size.
everything was cool except the rear chain guide needed to be shaved a touch to clear the 1100 cyl.
My FJ is 100% back together and running great so far....knock knock knock on wood.
I am 12 miles into the break in and plan to ride tomorrow Sunday and reach my 500 mile oil change.
The RPM rally is less than 3 weeks and I plan to be ready to turn and burn.

yes I actually took some pics , so enjoy my crazy method of engine installation.

Nice Job on the rebuild Mark!  good2

I just had to replace the Battery in my FJ also...............after having "slow-crank" issues for the past year, it finally would not crank at all.
New Battery and now it cranks like I pulled the spark-plugs out!   drinks

Mark,
I just got a battery off the shelf at Autozone for $104.
Its a gel type without a vent.
The guy at autozone said they are miles better than an acid fill and can take more irregular current like the Fj electrics love to throw out.
The standard batteries from Wally World are about half this price, but I'm thinking these are better value.
Only time will tell.
So far, so good.

I am checking on my options for battery replacement ... possibly lithium, but I think my charging system may kill it.  gonna flip a coin.

If the engine quit running because the battery died, that means the alternator is not working. A new battery won't help.

Let me clear that up... I rode 50 miles and stopped to hydrate and smoke , when I tried to start the bike the battery was dead 5v. The alternator is fine 14.2V normally when the engine is on.
I knew I might have a dead battery before i went on the ride but It had charged up from being flat. I was surprised it charged at all being an agm .

Anyway I replaced the Battery with a new agm again and this time I will pay attention to it....Ha Ha.  rofl

Moving on ......  The FJ is running great and rebuild smoke is almost gone , still have some on deceleration but I only have 350 miles on it. 
power is good and strong . I went riding with Zari and George on sunday and had them watch my smoke . We rode around Coloma area on the roads some of you may remember from the WCR a couple of years ago. I tried to keep the revs down for break in time and Craig had brought along his default stepson who was riding a Hyosung 250 thumper so i rode in the back to watch him . This kept me from going crazy and just winding the shit out of the motor... however I did succumb to my inner demons and blasted up to triple digits once or twice.

So I should have the oil changed at 500 mi just in time for the RPM fall rally ...  good2
