wacko2000 Posted December 6, 2007 Report Share Posted December 6, 2007 I need to know what size drill bit it will take to turn my stock pilot to a 27.5 I am goin riding this weekend, Im currently running a 30, and its to fat, none of the shops around me stock these and wont have them until next week.. anyone have any ides for me to try, I have no use for the 25 so It cant hurt to drill it out for know until the 27.5 comes in some time next week...

RIPRuck Posted December 6, 2007 Report Share Posted December 6, 2007 Why didnt you just have them sent priority mail? I'm sure Jeff has them and he'll next day ship to you! I needed a certain needle (which was hard to find) for my single to go riding that comming weekend which was 2 days later, called up Jeff paid a little extra and had them the next day..

wacko2000 Posted December 6, 2007 Author Report Share Posted December 6, 2007 yea thats doesnt sound like a bad idea, but i ordered them for the local stealership already, I will call him tom i dont mind eating the 10 that i gave the stearlership.. It cant be that hard to drill them though, i kno that there was a shop by me that used to do it , they drilled my brother 250 for him..

brian Posted December 6, 2007 Report Share Posted December 6, 2007 Those pilots have really tiny holes in em. Even if you could find out the size, the drill that size wouldn't be found in a standard drill index. You would have to try to find one elsewhere. It would probably take more time to find the drill than it would to get the proper jet from FAST. Also, it wouldn't be as easy as drilling out a main jet. If you are not perfectly steady you'll break that size drill really easily. Just my opinion, but modifying a pilot would prove to be more trouble than it's worth.

When you drill them grind off the jet number, you don't want a jet marked with the wrong size. Quote Link to comment Share on other sites More sharing options...
dajogejr Posted December 6, 2007 Report Share Posted December 6, 2007 As said on the E2S. Either leave the 30s in and turn your air screws to 2.5 turns out, or put stockers back in and turn the air screws .5 turns out. People drill main jets for methanol because you drill them from .110 to .125. Easily found in a drill index... You'd probably need a .00 something for the pilots...and when it's all said and done, how do you know you're not going to plug the small holes on the outside... You're going to ruin your weekend of riding by taking this chance? Use the air screws.... Quote Link to comment Share on other sites More sharing options...
badassbanshee479 Posted December 6, 2007 Report Share Posted December 6, 2007 yeah.. dont drill it... screw it. :biggrin: sorry could not resist Quote Link to comment Share on other sites More sharing options...
wacko2000 Posted December 6, 2007 Author Report Share Posted December 6, 2007 (edited) Okay I need some help.. played with the pilot and air screw today, I left the 30 in there, I started at .5 out and work my way out, at .5 it was smoking alot, as I turned it out .5 at a time the bike got louder It ran the best at 2-3 turns out but it stop smoking and when i put my hand byt the pipes there wasnt much pressure comin out.... some help please? Also I did the carb trick, I pulled the choke out half way, and rode it, It got worse doesnt that mean that I am to rich on the pilot and it would be safe to lean it out?

LiftdT4R Posted December 6, 2007 Report Share Posted December 6, 2007 Sounds right, as you turn the screw out, your leaning out the pilot mixture. With that big 30 jet your gonna wanna be somewhere in the neighborhood of 2.5 to 3 turns out if your still running the stock box with a lid.

wacko2000 Posted December 7, 2007 Author Report Share Posted December 7, 2007 Im still running the stock air box but, No lid Right know I have it set at 2.5 out, but I was alittle nervous bc shee was barely smoking, dont know it thats okay or not...

brian Posted December 7, 2007 Report Share Posted December 7, 2007 (edited) keep in mind that you are only dealing with the low speed circuit here. idle to 1/8th throttle. you dont need to worry about burning up the motor from being too lean at this range. it wont act right if you are too far off. just adjust the air screw until it idles right and comes off and returns to idle smoothly. then it will be set right. it is not required to smoke to be running properly. that depends alot on the amount and type of premix oil you use. mine usually only smokes (very little) when it is cold. when it warms up there is almost never any smoke.
