Dynojet
 

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."

After doing all that, it must be running like shit with the standard jetting !!

Oddly enough it is running quite well.
Took it for another dyno last month with a restrictive silencer, tried it with snorkel in and out. Smoohte with, slight blip at 5250 rpm out.
Now I have a much less restrictv silencer and I can tell the difference in performance but still runs well.

The guy at the dyno offered to fit the stage 2 kit, same price as above plus 2 hours of his time.

Anyway I was wondering if I could fit the kit myself and if I need any speciual tools?

I have fitted the tyres, brake pads chain and sprockets, and exhaust, service and other bits myself but maybe working on a carb is a bit technical for me?

Well, I guess it's jetting pretty rich from standard. Take a look at your plugs and see if they're running too hot/lean.

Id be tempted to fit the stage 2 but do it yourself. It's pretty simple if you're methodical about it and a great way to learn they anatomy of your bike.

No special tools required.
