Project S4 base gasket/lean issue repair progress

If your taking the heads off then do the valve adjust on the table. Much easier IMO.

A big +1 on that.

Just a little nervouse about TDC and the belts.

You will eventually consider this the easiest part

I put the Duc in 6th, rotated the rear wheel, so I use a long screw driver, and wait till it pops straight up, that's TDC? Then what?

I know this may be obvious, so please excuse if you already know this, you must make sure you are at the top of the compression stroke. The best way to do this is to hold your thumb over the spark plug hole until you feel pressure, other wise you may be finding TDC of the exhaust stroke. Then just when the screwdriver stops moving up, before it starts back down again is TDC

I pu**ied out, taking it to Corse Motorsports. If I'm lucky, they'll let me watch. Too scared to cause damage.

Doing the valves is not that hard... Base gasket repair is no joke I think you may have saved yourself a lot of frustration and downtime.

I would still attempt the valves if I were you. When I did my S4 the first time (First experience with Desmo Valves) I worked step by step using LT's book and split the task up over several nights.

Man I work full time at Dell, am a recording engineer, boyfriend etc. I decided to let Corse do the work, I volunteered to come in and turn wrenches. We're dropping the motor, getting the frame powder coated. Maybe all a blessing in disguise. I was just scared trying to find TDC, getting it all back together, running compression test etc. We're getting this thing running for once.

boyfriend etc.

The ultimate time sink 

[fouramdesigns]

Still waiting. Hopefully should be done in 3-4 weeks. The vision in my head is nasty. Let's hope for the best

Bike is done, motor turned out to be solid. Thanks to Alain and Phil at Corse Motorsports Nashville. Will pick up shortly, waiting on some goodies from Pigmy. Now to decide on new Termi's, MiVV or Ex Box. Wish I had the time to send to Boom Tubes.
