Just bought some AAEN pipes for my 01 SXR 700. Does anyone have a good setup for these? Mostly trail and lake riding in upper MI. Interested in reliable setup don't need to be on the edge.

My sled is currently all stock.

Thanks
 
i got a set on one of my 98`s (srx) and i belive it has 150`s straight across on it ,,,just now seen you got a sxr not too sure there
 
Those are going to wake the crap up out of your sled. You'll be amazed. You have to get some clutching.. I am running bender pipes and had to put in an RX1 heliz plus diff weights and spring etc.
 
Thanks for the replies, keep em coming.

I am getting the tuning sheet with them, just wondered if there is any knowledge that differs from what AAEN tell me or should I just set them up per there instructions.

Anybody know what clutch springs and weights?
 
Aaen sells a kit with his Blue secondary spring and
2 primary shims. Still using stock weights.
I used this in my 600 to start with and worked well.
 
Ok just got the pipes delivered. They look pretty good. Thanks MM800 you are a good guy and sent me everything you said you would.

Couple questions:

There are some small holes next to the cylinder where it looks like some probes were installed. Any suggestions on the best way to close these up. I don't have a welder, but could take it somewhere if i had too.

I also got a black and yellow spring and a blue spring. It says to use the B/Y in the primary. I assume the blue is for the secondary. I have rebuilt engines but never done any clutching. What do i need to do a good clutch rebuild and do I need any special tools. Also, do I need to do the clutches right away or can I ride with stock clutching?

This is probably a dumb question but here goes anyway. The directions say to increase main jets 1 size, but because of increased vacuum a large jetting change should not be necessary. Since the stock jetting is so rich anyway do I really need to go up one size?

I'm sure I will have more as I get into this. My goal is to have it still be reliable and not finicky when done. I don't need to eke out every bit of power available.
 
If you use aaen's set-up the clutching is real close
and if anything you can always add clutch weight.
Aaen's set-up is general so rider weight, etc will reflect
your final clutch set-up. When I ran my 600 with these
pipes I ended up using 1 size larger pilot jets, 4 sizes larger
mains, and raised needle 1.5 slots. This was spot on trail safe
jetting for my sled. Watch your needle jets as these pipes
like more fuel in midrange.
I suggest you read Mrviper's jetting page in tech section!
 
Thanks for the reply. I am pretty familiar with reading plug color and piston wash, but I will probably read it one more time. Can't hurt to refresh my memory and its better than screwing up my engine.
 
Another question.

If I go up one jet size do I still maintain the staggered sizes. You know what i mean, the stock PTO jet is a 145 and the others are like 143.5.

So logically I would think that I would just increase each jet 1 to end up with 146, 144.5, 144.5.

i would still stagger the jetting for starters. also, start out w/like 148.8 mains or 150's to play it safe. keep an eye on plug color and piston wash, and then determine jetting changes from there.
 
That's a good idea. So go up like 3 or 4 sizes and work down till I get it right then?

Also, this paper I'm looking at says "AAEN Blue Sec Spring, Install spring 9 and 2"

What does that mean.
 
Keep the staggered jet sizes.
9 and 2 refers to holes in helix and secondary clutch.
The holes are numered. You will see what I mean when
you look at your helix and clutch. This is the spring twist
in degrees. 9+2=11 or 110 degrees
 
Ok thanks

anybody have any ideas for plugging the probe holes? Could i just run a screw in there?

Also, are there bushings and other wear parts I should buy for the clutches?
 
I just want to mention to watch your needles as
your main jets are hardly an issue unless your wide open
for 600ft or more. Needle jet will cause a burn down
first. You could try welding to fix those holes but unsure.
Get a clymer manuel for your sled and you will have the
wear specs for your clutches. Recommended

it would be 110deg w/a yamaha spring, but aaen sec springs are wrapped differently i believe, where holes 9-2 is like 60 deg or something like that. hauck red sec spring is like that.

sure, start 3 sizes fatter on the mains, and work down from there. whatever the stock mains were for you, increase them by 3 sizes and go from there. also, i'm 99% sure you won't need to touch the needles.....stock setting SHOULD be fine. also, i would weld a small patch piece of sheet metal over the egt probe holes.

will probably have to mess w/the pilot circuit, w/either the fuel screws and/or the pilot jets.
