pilot jets- can't unblock them

I'm having an issue getting the pilot jets cleared out on a 97 gsxr 600. 3 out of 4 are completely blocked. I've run them thru my ultra sonic cleaner twice, I've tried using fine wire to push thru, I've tried carb cleaner, soaking in acetone & heating them with my hand held butane torch. Nothing seems to work. They're $20.00 each here in Canada from the dealer.

Any suggestions.

yeah, I think I should just give up & get new ones.

Thanks for the link.
 
AWESOME cleaner

AWESOME cleaner

You might think this is nuts, but this cleaner is the best I've found-
It's AWESOME cleaner from the dollar tree- I buy it by the case-
Everything from plating metal to gun cleaning- it soaked the fouling right off my combustion chambers like it was nothing- Only a dollar and I think a good soak and the wire from a bread tie and you might be ok- last ditch is a new set.

Everyone seems to like to recommend vinegar or Pine Sol if you can't use the Berryman's.
Have you tried soaking them in either of those?

I use this in my Ultra sonic cleaner works great
 
Sweet! Yeah it is super stuff! I wouldn't use anything like vinegar since it's acidic- pine sol not a good degreaser.
 
Try boiling them in a saucepan of water with washing powder added. Not too much powder or it'll be all over the stove.
 
The only way to guarantee that your jets a completely clear AND the correct size is to drill them with a pin drill.

Try the shank (blunt) end in the orifice first for size, then gently drill the jet orifice clear by hand. hold the drill in the pin vice and then twist the jet onto the drill with your fingers.

You will need a very small drill for the pilots, somewhere between #77 and #80. If you're paranoid, start with a smaller drill (bigger number) and increase size from there.

This is the only way to get an accurate hole size. A wire may not completely clear the crud out of the hole and may also scratch the walls of the orifice. Plus, with a pin drill, you can enlarge your jet size if you want and it is cheaper than buying new jets. YMMV
 
While buying new ones sound like the best option at this point, I would recommend trying the old fashioned method handed down to me back in my youth (circa 1970) because it's low cost and low effort.

Take a small container (i use Fuji 35mm film canisters) - put the jets in, fill it about 1/2 full with carb cleaner, snap the lid on and shake gently for 30 seconds. Now, put the container in your pocket and do whatever else is on your list for the day. Take it out every hour or so and shake it for 20-30 seconds. A day of agitation (which continues while you do other stuff) should do the trick

THIS! The best post in this thread. The same way I do them. Ray.
 
wow, the versatility of the gs'ers never ceases to amaze me.

Thanks everyone, I'll let you know.

Paul,

That's the beauty of the GSR

No matter what the problem, someone has solved it in their own way
 
like Kat said Guitar strings,strong and as you work up in size have a winding that cleans really nice.lol

without scoring the orifice either as the windings are round wire

Ahhh, so you carefully polish the cut end of the wire so it is hemispherical. Very clever.

Otherwise the cut end of a wire may be round in cross section, but rather sharp at the edges.

I don't know that this is really a big deal, but when the cost of a good set of pin drills is less than $10 (less than the cost of a set of new jets), and you can use the drills many times over many years.... just saying. YMMV
