Made some changes this season.
Bought a FireBall antivib +2 stem. Liked it but that was too high since i already had a high handle bar. Bought a lower one and better like the driving position now. BHQ bar clam and pipe hangers
 
The funniest thing about last season is that i did it at +9 timing due to a fuckup on my part. But i had hard time jetting it perfect cause of it. I was at 122/189 timing, 45/170 on pwk 35, cel on leanest clip(top) . Sniper pipes.
 
I also added pankace bearing. Did the clutch 3 times lol. I putted the longest screw and it was rubbing against the cover. Took me 3 shots before i found the issue lol! Working A1 now( putted the shorter one)
 
My jugs are now at 125/195. Work have been done on exhaust shape etc.
 
I was running 23cc domes at 137psi. with 91 pump gas.
 
Now i'm with 20cc domes and 100LL avgas. Didnt check static compression yet.
 
Took it back too +5deg of timing.
 
Now i'm at 160/45 with clip on top of the needle. My engine seems too like lean middle.
 
Will do some tests with 163 mains soon.

New chain is stretched now, cutted it too long, should recut it today.

iirc doesn't lower port timings increase compression? shouldn't those 20 cc domes put you above what you were before with higher port timings? or am I getting something mixed up

Yes, lower timing give a little more compression.

 

My gauge suck. I putted a shorter tip and got 150psi now, i will try a new gauge, i should be neer 170psi with 20cc

The compression number will be lower with the exhaust being larger.
