Drove to the dealer to pickup the S4Rt. 
Stuck in traffic for 3 hours on the way home

Beer
Sleep

Will try for tomorrow

Oh...did I mention the dealer who told me he had a dowel pin for me.....didn't.  Gee, thanks.  I get to wait another week now.

I suppose I could do that.  And just drill a hole same size as the other one. (Oil feed I believe)

Thanks!

Those are jets for the FCR's

Doing some work:

Indexing the pistons




Vid showing the cutting


Head is on now, with solder to ch\
check squish (no base gasket)



Break for lunch - done
Headed to lowes to buy a 15mm wrench...so I can make another head nut torque tool.  14mm would have been nice here ducati (so I could use the other one I just made weeks ago)

[TAftonomos]

Squish measured out at 1.06mm on the tightest portion, 1.10mm on the largest part.  Looks like I'm good to go w/o base gaskets

I want to confirm the orientation of the piston before I button it up completely.....


Can someone look at the above pic and let me know if the piston is oriented the correct way?  Intake on left.  The depth measures the same, but the done is biased towards the right (exhaust) side.

[brad black]

looks right to me.

[TAftonomos]

It's a roller now. 





Some leftover Ti bolts I had laying around.  Looks like I need to order some washers too.  Spring was 5 mins with a wire brush/drill and some WD40.

that kickstand bolt looks like shit.   

is the swingarm aluminium or steel?  I can't tell it looks like one of the box alu ones.  powder coated?

you can use either 14 or 15 mm nuts, i think mdmetric has the right type of 10.8 nuts.  

the 14mm wrench is much easier to work with, 1mm is a lot in that space..

[TAftonomos]

Aluminum arm, PC'd

I just ordered a TPO kickstand nut, thanks 

I made a tool from some kobalt junk.  Actually it may not be junk after all...tore up a dewalt sawzall blade trying to cut it down to size.
