I have access to a youshimura and an fmf pipe off of a king quad 700, will they work on my 250? what gains or losses will I see and also which is a better pipe? thanks, Paul

The Yoshi pipe is most likely better(depends on model). I doubt that the mounts will line up, mock it up and see what you can make work

Yoshi is probably the bettter pipe.If you have a welder and some fab skill you can make anything work.As for gains they will be minimal.If you open the airbox and jet it you will have much better gains.

 

[Paul07]

so it won't hurt anything to run the pipe off of a 700 on a 250?

Nope, as long as you adjust your jetting accordingly.

 

[Paul07]

does anyone know what jets to add and do I need to change them even though it is just a muffler and not a full system?

 

[Redracer]

Put it on and start the machine, if you have any bogs in the throttle you need to rejet. Or if you have a lot of backfiring on decelleration, you need to rejet.

What he said ^^^^^^^

 

[Paul07]

my local honda tech just informed me there would not be enough backpressure and that I would never get it tuned correctly w/ either pipe. So I may pass on the deal but thank you guys for your help

 

[Redracer]

I don't believe that, I have seen a guy put an exhaust off of a GSXR1000 on a 450. The 700's pipe is not going to be that much bigger.

Agree^^^^ they just want you to bring it to them.

 

[Paul07]

ok not to drag this thread out any longer but how bout a pipe, head pipe and muffler, fmf, off of a 300ex? the way I understand it it is the same pipe assembly as mine. Pry easier to mount and dial in correct? and what is the possibility the same jets will work?
