Re: ktm 300 exc
This has been mentioned before, most of us I know are running 165 main jet, 35 or 38 pilot, clip 2 from the top on the needle & 1.50 - 1.75 turns out on the air screw, If you was to ask a top secret I'm not telling you person to have a reply of " I had to figure it out so I'm not telling ", but then all you do is ask a certain other 300exc person & all is revealed , power valve spring depends, if you have the Green spring in it's great for low down lazy torque & hill climbs but just takes a bit more to wind it up, yellow spring I'm on now & it was great for the Barmouth trip of open moors & forest tracks and a good all-rounder really, I tried the red spring on a trail ride & had to change it an hour or 2 into the ride as all it wanted to do was race off & I'm not up to the red spring, Besides most have tried the red & it's to silly for trails, they've all gone back to yellow or even green. spring will be trial & error & how you ride I think, hope this helps..

just trying to find a happy medium with the valve spring green seems a little boring red wants to kill me.. just found a yellow spring so fitted that..
as for jetting just found my main jett had snapped in the carb that was 168 so i fitted a 170 but run out of light to test so will go through it tomorrow...

We've all done what your trying to find out by trying loads of stuff, If you run with our set up: 165/35 clip 2 you probably wont get it any better, 170 jet is rubbish on fuel, I know.... I run out 2 or 3 times on a ride & had to borrow some from the 4 strokes
