If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

pilot jets- can't unblock them

The only way to guarantee that your jets a completely clear AND the correct size is to drill them with a pin drill.
... hold the drill in the pin vice and then twist the jet onto the drill with your fingers.

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

I have great problem with this suggestion.

Yeah, it's going to clear the jets, but what size will they be when you are done? Do the jet sizes exactly correspond with the drill sizes? You are doing this "by hand". What will prevent you from drilling at a slight angle, which will give you a bigger hole? Even if you do manage to drill it straight, it may be "accurate", but is it the right size?

Personally, I think that drilling out jets so they no longer match the numbers printed on them will turn me into one of those "dreaded previous owners" that we all cuss so regularly.

Thanks, but I think I will stick with my method of soaking the jets in Berryman's overnight, then using a strand of copper wire (softer than the brass, but harder than the crud) to clean out the holes. :o

all the suggestions are great, but why not just get new ones and not worry about drilling them too large, or anything like that, by the time you buy the drill bits, the berryman's (we can't even get that) pine sol, wire, this that and the other........

for about 40 bucks you will have new jets and probably no more headaches

well it's the way I would do it at least, at times this works out great "KISS"

by the way Paul.....let us know what you did

Steve - I am completely comfortable with using COPPER wire after a soak in Berrymans or similar carb cleaner. I am not so comfortable with using steel wire, such as the wire from a barbeque grill brush!

Also, in my experience, carb cleaner and wire is not always sufficient to unblock a pilot jet. I have "cleared" a jet with wire, then found that the flutes of the pin drill will be filled with gray crud after running that through the jet. This is why I just go straight to the pin drill and skip all the soaking and poking!

Finally, I have never gotten bits of brass on the drill unless I was intentionally trying to enlarge a jet.

Your mileage may vary. ;)
 
AJ said:
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

I can agree with that,guitar strings are 7 bux a pack, i save my old ones tho so for me it is no biggie.I didn't know the drills were that cheap.

AJ, never mind, they don't like your idea so don't want to hear that it WORKS & does NO damage to the jet unless you TRY to modify them. And for you doubters & newbies that are ASKING for advice, I have been doing it this way for over 35 years. Yes, I speak from EXPERIENCE. That's why I seconded AJs answer about this. Ray.

Oh found a helpful chemical about a year back. I work alongside an outboard technician at my shop and questioned him about the cleaner he was using for cleaning (I'd always used a 50/50 mix of Yamaha dip and fuel, along with the Maxima Contact cleaner for spray, along with a selection of old float needle wires for the stubborn stuff).

Anyway he was using a product sold by Mercury called "Powertune", actually intended for use as a spray engine decarbonizer, he'd always spray enough into the loose float bowl to soak a single carb's jets, and leave some in stubborn passages to free up what compressed air or contact cleaner weren't helping. It's a little frustrating in the fact that you can't just pour it in a bucket, but I've been most impressed with the results, and hell the brass actually comes out looking like brass.

Maybe ya'll will like it, maybe ya'll won't, but i'm fond of it. :D
 
Personally I'd run one of my 5 sided watchmakers broaches through the center of it. Why you ask? because that's what I have on hand. ;)

I save all of my cut offs... I have a coffee cup full of them. They come in handy for MANY things...
 
For me, there are situations that merit cutting your losses & moving on, rather than spend a couple of hours on something that "might" work although I appreciate each & every one of you who took the time to reply.
I decided to purchase new ones. Spent about $30.00 & I know they'll be right.

Thanks everyone,

Paul

Ya can't go wrong with that approach, and you'll have complete peace of mind. (plus a sweet riding bike again!)
