Well how's that big ole motor treating u? Been a while but almost done and might have gotten i n a little deeper. Performance and cosmetic...Can't wait now. Hey u still like the Rivera pro? Just started on the chassis as racing is over for this year and no snow plowing as of yet. Brembos front and rear as u said it needs to stop. Anything else u have found u like to share. Fuel pressure staying ok? No need for electric pump? U build a diff gear box?
Thanks in advance

The big engine finished the season strong, pulling back the compression made it start easier and tamed down some heat, runs smooth in normal conditions but still has a giddy up button.
That Rivera clutch is the catazz, clutch pull is less that stock, hasn't slipped one time pulling a big bike and donut eating rider.
Have a Baker trans but don't thrash it, have stayed away from throttle whacks and power shifts, don't need either with the torque of a big engine. Have a Screamin Eagle side car drive belt but still try not to test it. Did a couple of whacks with one of them cool with the front wheel lifting and the other ruined underwear, left it alone since.
The Ultima R1 with a Tjet is supplying all the fuel needed, have the AFR's on the rich side in WOT and AFR's numbers stay consistent, believe the Pingel helps also, no pump needed.
Yes brakes are VERY important when pushing a big bike past it's designed areas!
What changes have you made? you may need to wear a adult diaper when you run 3 gears

Deers are smarter this year than I am, currently at 0 but have been picky. Coyotes invaded my property and might be picking up a AR Varmint riffle tomorrow, putting an assault rifle to good use to shoot those ba$tard$.

I'll look up the number for the clutch and have the middle of the road ring gear set up, one ratio above the 66 tooth. It was also a Rivera product and was in the stroker motor before the big one, has held up well.
Sachs said the Ultima heads are bottle necked some and can release more power, he had my ports on the original heads opened up after looking at the new set of heads, really hit hard but was on the peaky side.

Turned 60 years young and motor finished up all on Xmas eve. Time for motor mounts. Clutch and the dreaded oil lines now. Maybe air breather for that fatazz 48 mukuni
