OK all of you that have piped and put a K@N filter on, what size jetting did you end up with as I am getting ready to do the same and would like to know were to start also what is your elevation.

Thanks,
Dads400

 

I have a Yoshi slip on, K&N filter and the top plastic part of the snorkle off. I am using a 152.5 main. The elevation I ride is around sealevel to 400 feet and 70 degree temperatures.

 

I went with the full Yoshi system and with the lid off 152.5 jetting was perfect. Elevation 0-1500ft and have only one complaint; the rev limiter comes on much faster with the new pipe. Waiting on rev box to start shipping.

 

Even with the Yoshi slip on the rev limiter hits immediately in 1st and 2nd but not in 3-5.

 

I never hit my rev limiter cause I shift. I also have the lid off, K&N, no snorkle, HMF pipe and am running a 152.5. It seems perfect.

 

Trinity pipe, lid and snorkle removed, 165 main.
