Just wanted to know when jetting is necessary. Have really come to the conclusion that I dont know Sh*t about four wheelers.

 

Jetting is neccessary any time that your quad doens't run to its full potential due to the air/fuel problems. If it sputters at all, in any range of rpm's......then you can change something in the carb to fix it.....to run better.


Generally, assuming your quad is already jetted correctly, you need to rejet when you open(add more flow) to the exhaust or intake(fuel and air) systems.........


The quad is not neccessarily jetted appropriately from the factory, generally they are a bit on the rich side.....to be safe.



To check if you quad is jetted correctly:
Put in new spark plug(helps...but not neccessary)......go out and ride for a bit(not slow)......and then hammer on it and run it full throttle for a good amount of time, and then immeadiately shut it off(with no idle)......check the plug.......if jetted correctly, should be paper bag brown down in the plug.......if black, you need to go down in jets.......if white......more fuel(up in jets)......

 

Thanks, so i should re-jet after i put my full hmf exhaust and new air filter

 

Also will this cause my bike to run hotter.

 

Yes you should definately rejet......but I would run it once, and do the test I told you to do......and see if you need to actually rejet......



I'm not sure on what your bike is.......but if it is a raptor, I think they come a little rich from the factory, so you might not need to rejet.



You bike shouldn't run any hotter, if anything it might run cooler(getting rid of exhaust quicker with less restrictive exhaust)

 

ok cool, on a scale of one to ten how hard is it to re-jet. i went from a street bike to a four wheeler, so i dont know a lot about these things yet

 

I couldn't tell ya on your bike(don't know what it is......please tell me).......but on mine it is about an 8(easy).......the first time is a learning experience......and the second still takes a while.....and by the third time.....you are learning tricks to make it go quicker....

 

Sorry lol 06 Raptor 700R. I want to get these things done so it runs cooler. the temp light keeps on coming on and i think these things will help it

 

temp light huh??? Is it the engine temp(coolant).....or is it the oil temp?? I personally know nothing about the 700r.......not many people do, its just too new yet.

 

the coolant light, i have been trying to figure out if anyone has had the same problem with the 700. When you re-jet do they show you how to do it. Dont mean to sound stupid, but does it come with directions
