AAEN Pipes

mopar1 you are correct aaen's secondary spring
is different, but aaen is using 9-2 in his set-up
instructions.So what it ends up as actual degrees
I guess I am unshure but aaen knows. I am just
using aaen's set-up but you could use a yamaha sec
spring.

oh, not saying to not use holes 9-2 w/aaen spring, just saying don't expect 110deg of twist in holes 9-2 w/aaen spring, like you would have w/yamaha spring.....that's all.
 
Yeah somewhere I read that I will probably end up with my pilot at 2 turns. Its at 1 1/2 right now, thats where I put it when I cleaned the carbs last year.

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.

No problem mopar1
I would like to know specs myself.
I know aaen blue is between yamaha
red and green for spring forces, but that
is all.
 
Proper Set up

Heres the deal! Go with the instructions! Aaen has not been around this long building crap! Go rich! Check your plugs. Darker than peanut butter (for real safe) jet down. RPMS will come up with the leaner jetting. Add weight to the tip. Check plugs. With the new load did they change? If not go leaner. Load the motor with more weight. Does it still look rich? If it is leaning out , play with the rivets in the different holes. You have to undeerstand that the harder you load a motor the more fuel requirements. Always richer. More load more fuel. More load equals more weight. These pipes like rpms 9000-92000. Find the point where you can pull that weight to that rpm with carboard plugs and you are making some seriouse power
 
Thanks everyone I think I have enough info to feel good about starting. First I'm going to weld the pipes and paint them then rebuild my clutches when I do the new springs. Probably have to wait for colder weather to do any real testing, but I will report back after that.

I really appreciate everyones input.
