Also put a 1/2 hole in the silencer baffle. It runs out a little better, not an impressive difference though. Haven't checked the mileage with mods yet, keeping my fingers crossed.
Funny thing is, I never jetted my first bike. It got 58 when new, and then I modified a KLX300 silencer to work with the stock header, and it still got 58. It was definitely lean, but ran ok.
I'm hoping for a big torque gain with the 351 so it'll pull 6th easier.
FWIW, this one seems to get 50 even when I baby it. I'm not too concerned, but I'm hoping it stays at 50 or even gets better with the 351.
no need to go to the 40 pilot the stock 35 is more then enuff
