Maybe the tech did your upgrade a week ago on another bike and they ended up changing the jet after they got the bike on the dyno.

 

I think a good Dyno tune is worth it to get the most out of you bike. On my XL50 I did the pipes and it did not run right, pipes got too hot and other issues, so I did the Stage I AC and PC III with a pre-made map, well tired a bunch of differant maps and it still heated up the pipes too much and did nto run right. I tried to tune the bike myself with the Dynojet program and laptop and I got it better and the bike was faster, but it was running too rich, but I had to get it so I could ride it to the dyno shop. After the dyno tune I picked up some nice HP, the bike ran better than new and no more glowing pipes. Do you have to have a dyno tune? NO, but ask yourself if you want the most out of your bike and want it to last with the new mods then go from there.

 

I'd do it if it was a race application that I was trying to get the most out of. But for the average street rider with a stage 1 or maybe even a stage 2 I sure don't think its worth it. Seems to be a pretty even split of those that do and don't so probably no right answer.

 

Anyone ever had their bike in for dyno and tune, and been told that there was really nothing they could do, that your bike was tuned correctly?? Probably pretty rare, You could take the same bike to 5 different tuners, 5 days in a row, and I'll bet they will all "fix" or tweak something to justify your bill.

Seat of the pants is all that matters to me, the way my bike feels is more important to me than what a slip of paper in my pocket says.

 

Dyno tuning is overrated. A waste of time and money unless you have a problem or you are racing.

 

I don't understand how guys spend so much money on the bike and then skimp on the tune. Wouldn't you want to maximize your perf. mods ???

 

A dyno tune is only necessary if:
You want to maximize the potential of your motor (stock or modified) by subverting EPA mandated leanness.

Run cooler (see above)

If those are your goals, your dealer is correct. If not, well, it's your call and your bike...
