Quick question, I have done the same mods as above with same bike and when I put it on a dyno yesterday the max hp was 33.7 and torque was 24.3

Tech mentioned that it looked a little lean possible on the main jet and the needle...what should I see, I am located in Vancouver...sea level

Thanks

alright... dumb ass question #1062

are you guys putting the washers from the stock needle back on?

why is it the "SM" uses different jetting than the "S"

what kind of dyno?

open yosh pipe or cork in it?

"looked a little lean possible on the main jet and the needle"- what were the a/f fuel ratio readings at wide open throttle and steady throttle?

It is an open Yoshi pipe, I am new to dyno testing etc so not sure of the type of dyno, attached are the printouts, no a/f readings unfortunately.

It was a free dyno day sponsored by a local dealer and race club so :thumbsup:

Not sure if you can come to any conclusions but any tips will help :thumbsup:

Well, I am not using the nylon washer. The Dynojet needle is adjustable. Therefore, you can set the length of the needle (by setting the clip position) to be equivalent to utilizing the stock nylon spacer. Mine is set on the last position (6th) with only the thin metal oem washer. This is the same as setting the clip position in the second slot and using the nylon washer. If you think about it, the taper of the needle is only dependent on its relative length. If you have the same length, it doesn't really matter how you get there (nylon spacer or clip position). The nylon spacer was probably used due to the fact that this particular needle may have been used in various applications. Being that the stock needle is not adjustable, the spacer was used to get the desired setting.
