I have a Graydon Proline pipe/silencer and i have 10 1" holes in my airbox lid...the problem is that it is starting to heat up a lot and when i give it gas at high revs it skips...so i jetted up 2 notches and it bogged out BAD when i touched the gas but didnt skip at high revs. i went down a notch and it still did it. so i left it the same with the small skip. Any ideas on what i should do?

 

What do you mean, jetted up 2 notches? On the needle, or the main jet. If it is skiping at high rpm's then you might need to raise the main jet. I am not completly sure so don't go chaging things until someone that has more knowledge resonds also.

 

I too am a little confused by your explanation. Exactly what did you do? I'm not sure what you mean by "notches". Over heating can be caused by a lean condition & the problems get much worse with continued use. Put your jet needle in the 3rd position (center slot). Then install a main jet two sizes fatter than you now run.Put in a new plug and test ride at 3/4 to full throttle for at least 1/2 mile.
Cut your engine & pull & read your plug for color. If it shows tan or light brown and you had no cutting out at full throttle you have the right air/fuel mix

 

so this is the same do on *********? I'm 300ex_in_tx or trx300ex. later

 

ok...thanks a lot for the help..i was misinformed.someone said to move the needle up 2 notches and do nothing with the main..so i should go up 2 with the main. what about the pilot?

 

BY the way (hondatrx300ex) did you ever find a Graydon Proline pipe?

 

whats the deal they won't let you say ********* on hear? nah I think I've changed my mind cause I've heard the graydon proline pipe doesn't add hardly any top end. I'm gonna be doing some mx racing and need quite a bit of top end. I'm looking at the supetrapp ids2 or white bros e-series.anyways see ya

 

I race mx and I get pretty good top end. I can do around 60-65 mph flat out. If you wanna race mx you are gonna need mid and low more than top anyway arent you?

 

well not the tracks around hear they are big long and fast! you just gotta haul to do the jumps. thats why I want some top end. today I rode a banshee for the first time. I like the top end of it but I got tired real easy cause it doesn't haddle quite as good as my 300ex. anyways I want a pipe that adds alot of top without taking any of the bottom away. later man

 

thats the opposite of most of the tracks i ride....they are quick and tight....jump right after jump. Yeah i agree with ya about the banshees too...
