Tool suggestion

I'm just getting back on a 4 stroke after having ridden ktm 300s for the past few years. I forgot how much more effort is required to access various components of the 4 stroke carb compared to a 2 stroke. I was able to change pilot jets, mains, and even pull the float bowl without twisting the carb on my 09 450 using regular tools but it was kind of a pain. I got to thinking about the tools I have at work (I'm a Mercedes master tech) and remembered my favorite tool for doing interior work. The skew driver.

You can buy the same sort of tool at Lowes. The one at Lowes is made by Milwaukee tools and does not come with a handle, but a 1/4 inch bit driver works just fine for a handle. I brought home various bits and found pulling the float bowl takes but a minute. I ground down a flat blade bit and use it for pulling pilot jets, attach a socket and the main comes right out.

The way I use it for work is attached to a cordless drill (these things don't like cordless impact drivers) but that seems a bit much for working on the bike.

Now you're going to have to get used to how tight everything gets with this and double check your work for a while to make sure you are getting the proper torque on the fasteners. Once you get a proper feel for it I think this tool could save you quite a bit of time and frustration. Oh and it works fantastic on vehicle interiors too!

Thats a handy device, I have something similar but a little wimpy comared to those things.

Maybe you could help a guy out? I'm working on a '98 slk230 with P0301 and P0304. No miss right now of course, do coils fail on these things? Guess I could always swap it with cyl 2 but I'd prefer to fix it and make some $$$

Handy tools, those. I've never found a need for one on mine, but I can see it being useful.

Have you seen this thread? By far the most trying aspect of pilot jet changes is getting the new jet started. There's a simple cure:

I ground the flat blade bit that I used so that it was just as wide at the pilot jet. I then took my dremel and made a nipple in the middle of the flat that locates the jet side to side. The bit is fat enough that the jet fits snug and lets me use the skew driver with no worries of the jet falling off the bit.
