Doesnt a 162.5 Jet seem too small for an after market pipe?

Thanks
Steve

 

I gues it kinda depends on your elevation, other mods, and oh yeah, IT WOULD HELP TO KNOW WHAT QUAD YOU HAVE!!!!!!!.

 

z400 with ct pipe

 

Not alway's,aftermarket pipe's alow the engine to breath better,you could be too rich.What's the problem?,is the "Z" bogging or back firing?

 

Is that what size CT recamended for you?Just curious.
My 175 is on the money but I have the full system no airbox lid K&N.It bogs when you first start it when the engine is cold till about a minute once warm then she rips & shreads.

 

Yeah, they recommended that jet

I put in the 165 but it ran like crap with the lid off...with the lid on the 165 was great.

Now with the lid off, K&N the 162.5 seems good....

You say 175? Makes me wonder...

 

Sometimes jetting does weird things, but don't let it lead you to beleive that a larger jet doesn't richen up the mixture, because that is how it works. Larger jet is running richer

 

no no I didnt recamend a 175 for you.Remember we have different pipes.
HMF = 170 slipon 175 full system worx great but I guess I lucked out on the elevation thing etc.
