Congrats Anne Roberts and Michael Barnes at Road Atlanta!

Entered 4 races and got 4 podiums. Very successful weekend and ran my fastest time in last lap of last race. Can't thank Michael Barnes enough for all the help on myself and the bike. The only times I've gotten to ride this year were at all the MotoAmerica races, so it was great to be back in a relaxed atmosphere banging bars with my WERA buddies at the N2 track day Friday and the weekend races. Bike ran really well thanks to Marc Wayne Salvisberg's tune and we were able to make some rear grip progress with the help of Craig 'Huey' Stewart. Dunlop 7455 compound DOT's were working well too. Not sure when I'll be able to ride next, but we are planning on attending the GNF in October! Until then, lots more dirt tracking at night after work and at the Russell Ranch. Thanks everybody

Hybrid Ceramic Wheel  Bearing kit

4 bearing set

2 front wheel bearings
1 left rear wheel bearing
(use stock right rear bearing)
1 sprocket carrier bearing

Why no RH rear wheel bearing?
Because it's a needle bearing and not a very good application  for a ceramic roller.

Tough steel races and almost  friction free ai3n4 ceramic balls.

Bearings are pregreased and ready to use.
Bearings have rubber seals that are easy to remove if desired.

"Hi Marc,
We are at Willow Springs and Dave's (2009) R6 is running awesome.
Dave has no complaints at this point and it was easy (at part throttle) to ride now. Thanks!"

They had used a different flash service. With that, power at high rpm was improved but track rideabilty wasn't good.
The Factory Pro Power Flash delivered the same high rpm power as their old $200 flash but provided seamless part throttle control for the smoothest cornering.

As I recall -

After a race's worth of running over 100 AMA and WERA bikes, we gained from 2% to 3% power,

The least I saw was 1% (JR's super loose built engine) and the most I ever saw was 4% (on a super tight street  built engine).

The other 98 bikes picked up 2% to 3% power - with most 2% and  2.5%

Lasts 2 and up to 3 oil changes (tapering off in effect).

RE: Translogic (same as Dynojet)  Quickshifter:
Just a quick followup, the Dynojet tension sensor does indeed work. Connect the DJ blue wire to the YEC blue, the DJ/green to the YEC red/white.  I have the trigger voltage set to 2.5v in the YEC software, everything works perfect.

That's not tested yet. It's here so I don't lose it -  Marc

The extension of the laboratory for engines of the Swiss Federal Institute of Technology was completed in about 1935. Its architect was Rudolf Otto Salvisberg (1882-1940). He had a successful career in Berlin but returned to Switzerland after the advent of the Nazis. His architectural style was somewhat similar to that of Erich Mendelsohn. The staircase of the laboratory is in normal use but well preserved.
