Dynojet

[03XT600E]

Is it worth paying £75 for a stage 2 dynojet kit?

I have already taken the snorkel out, piper x filter, big bore headers and less restrictive silencer.

Just been doing some reading and apparently,

"I found the jetting to be easier on my XL than my XT simply because both carbs are identical with the exception of having a choke circuit in only one side. I assume the Raptor would be setup the same way. I just bought a Dynojet jet kit for the XL600R and followed their recommendations. But everything that the YDIS carb needed was a struggle. Rejetting was a nightmare, setting the float height was crazy hard and adjusting the air screw required drilling out a brass plug."
"Just getting the float height set right requires a special Yamatool or a LOT of patience."
