I got my tune done today and I'm pleased enough at 103/106 it made the ride home in the mid 40s and rain not that bad. My question is, for the occasional incident where I have to get on it, where would be the best RPM point to turn on the shift light I have integrated into my tac? I currently set it to 5400 RPM. See dyno chart below.

Thanks.

You're still holding 100 HP at the end of the run which looks like about 6300. You first made 100 HP at about 5150. So, as long as it's pulling back at least to 5150 on the shifts then you want to shift at least as high as 6300. That puts your shift light at maybe 5900-6100 depending on how quick you react. Your RPMs are climbing faster the lower the gear is that you're in, so keep that in mind.

 

Well you should be happy with that 95' build, it's gota be fun huh.
Any way I'm glad you posted a graph with the shift light question because with out it that question can not be answered accurately. First off lets talk about 'After Shift' because this is much more important than the 'Up Shift'.After shift is how far the rpms drop when you shift up to the next gear, if you had a air shifter the rpm drop would be about 1000 rpm but since your not that fast your best shift manually will drop2000 rpm. Okay so now we know how much the rpm will fall after the shift is made so where do we wantthe rpm to fall to.....good question......your peak tq on your graph is at 4100 rpm, you want your after shift to hit peak torque because this is where the bike accelerates the fastest, knowing the dropin rpm is 2000 after the shift you want your shift lite on at 6100 rpm.Ifyou hit the 6100 rpm shift the after shift will hit at 4100 which is peak tq and off you go.
Now if you really want to get technical you should take into consideration that there is a reaction time from your eye to your foot....this is about 250 rpm lag so if your brain says to shift right at 6100 rpm the shift will really take place at 6350 (or close) so subtract the 250 from the 6100 rpm and you have 5850so your shift lite should be set at 5850 rpm's forthe fastest your bike will accelerate. How's that for an answer.....lol.....

 

Doc, you ROCK! I'm totally happy with the build. Answers like you provide are what keeps me coming back to this forum.
