42 pilot

[jeremyd]

would 42 pilot jet be ok to run with white bros air filter and stock pipe with spark arrester out?

[almostred434]

should be definitlywould get rid of the cold starting blues
just blip the throttle a fe times and it should start right up

[jeremyd]

i was just wondering if it would be too rich or not, will it cause it to bogg down easy.

[jeremyd]

will 42 pilot make it start easier with white bros rev box?

[almostred434]

it should start a little easier u most likely wont have to ever use your choke again and how is the white brothers cdi box workin
ive heard mixed thoughts about them

[jeremyd]

well i had it on there for a while, then i took it off. it made it really hard to start. will the 42 pilot cause any engine problems?

[almostred434]

no 42 pilot wont hurt ur engine

[jeremyd]

good, im new to dong this. i would probably be better off to take the choke off wouldnt i? i think ive heard of people doing this.

Honestly, I think a 40K pilot would be better for your quad. Everyone is quick to recommend a 42K but, that can be too rich of a set up for some.

[TRFOXX]

I used a 40 and it works great.

The only time I suggest using a 40 pilot is when your running a stock exhaust, otherwise a 42 with an exhaust won't be rich.

That's a bold statement.

agreed, especially once you consider that every motor is different, and we are all at different temperatures and elevations...

[Honda#4]

thats also with an air filter too. Otherwise you might as well go back to stock.

[rescue6]

As you can see in my signatue there is no way I can run a 42 pilot just because of elevation so not everyone can run a 42

[Honda#4]

If you ride in the mountains of course you can't use a 42 pilot. your quad would'nt even start.

[rescue6]

Sorry I just had to bust your balls a little since it was such a bold statement that you made about using a 42 pilot jet and you do call yourself "Doctor Jetting" but it is all in good fun man

[400exrapes]

i have just an hmf pipe with a 152 main and 42 pilot two and a half out and its too rich and a 148 the stock main is too lean so i turned the pilot in one turn and its still too rich should i put the old 38 main in or do i just need to turn the pilot in all the way

[rescue6]

How are you determining that it is too rich or lean ?
What elevation are you at?
What temp?
Airbox lid on or off?
Have you adjusted you needle?
You want to be 2-3 turns out on your pilot more than three you need a bigger pilot less than two a smaller one. so dont turn it all of the way in.

[Honda#4]

use a 155 main and the 42 pilot and take your lid off, put your needle on the 4th slot from top and turn your screw out 3 turns.

Honda#4 What several people are hinting at is you are giving very specific jetting advice that may not be accurate.
I try to suggest jetting that will get people in the "ballpark". Not every quad responds the same to jetting. There are way too many variables to nails it down to just one jet size.
I would recommend giving advice on jetting only if your quad is similar in set up to the one asking. I hate to see people misled or confused.
"Dr. Jetting"? Didn't you just learn a couple weeks ago which way to move a clip on the needle to make it richer or leaner? I did read that in another thread.

x2

you need to do it to your engine, You'll spend a good amount of time getting it right if you are not sure what your doing, sometimes it pays off to have somebody do it that knows what they are doing.

checking the plug color is the best way to make sure it's not to rich or lean

just my $.02

[Honda#4]

400exrapes try a 150 main then, if the 152 is to big and the 148 is to small then that should be close. Then put the clip on the 3 slot from top.

[Honda#4]

I'm sorry for the wrong jetting but he never did say if he was running without a lid and using an air filter.

I handle jetting questions everyday so cut me some slack not everyone is perfect you know.
