N8's '81 XS400 Special Build

Good to hear What kind of air filters are you going to use?

 

Or go with this one that has been shown to fit

RU-2970

I would go with uni's or k&n's they both are chargeable filters ( meant to be oiled). The mike knock off ones say they can be oiled but are NOT cotton gauze so the oil will not stick and fill up the filter like a real k&n will. I have used both and there is a big difference in how well they work.

 

http://www.xs400.com/forum/showthread.php?t=12025 If you can find a set of these you will still be able to use the H-pipe and they will filter/perform well.

 

Do you have a Dyno sheet to prove that?

 

Does anyone Much easier to tune than any emgo or mikesxs filter and better than stock

 

No I am just giving him a hard time. Being closer to a stock intake is likely to produce the best usable day-to-day low to midrange performance.

 

Glad to hear y'all like the gold leaf idea! Can't wait to see it. I would use it like shadow - not outlined, just on lower ends of sun rays, as an example (the suns shadow is gold, right?)

I am currently stock airbox with aftermarket pipes. Chris, I know you use uni pods, would you say they make your bike run nicer than stock boxes?

My understanding on higher flow intake is that you lose some bottom torque and gain some high end horses. True? Dyno aside, is there another good reason aside from style to upgrade to a different filter?

 

I have not had a chance to use my uni's yet but from all the research and talking to the xs650 guys it will be a upgrade from the K&N's I had. Also the type I have don't have a capped back so there is no restriction at all with them. When I went from using the H-pipe with a set of mikesxs filters on the end it ran better across all ranges than with the stock ones. When I put on the K&N RC-130's it ran better yet. It was also the time I changed to xs360 carbs Running uni's with and without H-pipe is the last setup I need to test but that won't happen for a while.

 

As long as you have oil-able filters you will be fine. If not it's just a screen and not a filter
