Update:
Today I put in a 50 pilot, a 400 main and left the clip on the 4th position. With the DG pipe it ran a lot better did not ping like it did before and still felt a little weak down low
I decided to tear it down and try the PFR pipe again
Fired it up on the 1st kick and took off .... felt like a monster down low but sputtered and had a hard time revving all the way out? I decided to play with the needle before changing jets again.
I moved the clip up to the 2nd position from the top and ..... Wow
Monster down low, revs good and doesn't ping
The only thing is it is like 65 degrees today and overcast. When its 90 degrees I suspect I will have to go back to a 390 or maybe the 380 main? Hopefully, fingers crossed, it will stay running this good!
I can't wait for the next race!
