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
