Guys... cost me about 6 bucks for one bit shipped, however, for whatever reason I didnt visualize 18 thousands when I purchased it... its small as hell. What did you guys use to drill out the enrichment jet with? I was thinking about running the bit through metal a few times so that it was dull so that it didnt grab and break.... regular drill and a bench clamp?

 

Do not do anything to your bike unless you know what you are doing or have researched what you are attempting, thoroughly. I do not have time right now to do a search for you, but there are quite a few posts (with pictures) on here about drilling that jet. You are right to be nervous, a mistake can get expensive quick. It pays to use the heII out of the search function, and have patience when you do the work .
Don't use a hand drill , use a pin vise, or something similar. The area you are removing stock from is thin dont use a lot of pressure.

I was nervous also, but it worked out ok. As people have mentioned, use a pin chuck. The bit that I ordered came with one. I did have the bit come out of the chuck while drilling, but I just retightened it and continued. My only question was how far to drill. It didn't seem real obvious to me when to stop.

But in the end, it was more then worth it. The bike is much easier to start. This forum is a great source of info. I thank all the knowledgable folks that help out.

 

I did this process last night in fact, on a 2010, while installing the jet kit. Got a 10 pack of .018 bits form Victor Machine for ~8 bucks, and glad I had more than one bit.. I used a needle nose pair of Vise Grips to hold the bit, but the knurled teeth was enough to snap the tiny bit upon clamping. Half a turn less force on the next one, and a few quick twists of drilling was all that was needed on the soft brass jet. This morning was the first cold(ish) start (45 degrees f.). Usually, it was a pain in the ***** starting in the morning, borderline unreliable for a new bike, and had me worried for camping trips out in the mountains if compression starting was not an option. Anyway, this morning, pulled choke, tapped the start button, and she fired up immediately, within one revolution of cranking in fact... problem solved.

 

i used the exacto knife handle to hold the bit and worked perfect. Just a few light turns and was done...

 

He said it all. I used needle nose vice grips too. Just a few turns of the bit BY HAND and you are through.
