Yoshi Rs-2 Dynojet stage 1 kit

Just installed my yoshimura rs-2 and rode it a bit, was going to install the dynojet kit (Tucker rocky #409880) but from searching it appears that my jet numbers are off from what is mentioned (dj128-136) where it is mentioned here about 150 main jets and 155.

have a twinair filter to install as well. should i just do the 3x3 mod as well?

i travel all the time, so i will be at varying altitudes (today at 4200 feet) last week was at 2000 feet. where would be a good middle road on jetting so i dont have to change all the time. Thanks for the help

SM or S?

2007 s. 150 miles:ride:

that kit was intended for the unmodded air box.

you will need to run a 150 main for the 3x3 mod and pipe.

alright. so put off the 3x3 for a bit. and run the 136? or the 134 (which it recomends)

I would go with the 134 at the altitudes you are riding, but at sea level you will be lean. It would be best to get the right jets and do it once.

134 for know. thanks ill let you know how it goes. instructions say clip on groove #4 from the top stick with that?
