Glad you got it sorted. Using 140 mains suggests that your exhaust is probably a bit restrictive in some way (manifold and/or can). If you get the urge for a bit more power you'll know what you need to improve.

Anyway, enjoy driving!

very glad you posted this topic. i am just fitting the dynojet kit and was not sure which hole the main air jet is. the manual is about as clear as mud.
I will set it up as per the instructions but at least i know to go to the 140 mains if necessary. Which position did you end up with the needle setting. 1 to 6... 1 being at the top. cheers Paul

Mine is currently set to the richest groove on the needles - that is with the needle as far out of the jet as it goes.

What I did was try a selection of grooves each with the 140 and 144 main jets. I drove at low engine speed, mid engine speed and high engine speed at low throttle, mid throttle and full throttle to see how it felt and sounded. I also tried rolling the throttle on and off plus snapping the throttle on and off.

It was terrible at some settings, marginal at others but there was only one setting where it was good at everything.

I think, to be fair to Dynojet, the kits are designed to be used on bikes, most of which will still run the standard airbox, and the mods might be a new air filter and exhaust and / or can. This is the sort of range of adjustment they are looking to cover. (Although I do agree the descriptions in the instructions could do with being a little clearer!)

We have a foam filter and a much better flowing exhaust system. My dynojet kit for the ZZR came with a range of needles and jets. I fitted the 155's to start with and the clips on the needles as instructed. As you found it was very rough and spluttered.

I spent a few days experimenting with needle position and jet sizes. Eventually settling on drilling the mains out to 205 and the needles right out with two washers under them. Now it goes like a rocket.

I am planning a trip down to Holeshot next month to get it set up properly on their rolling road, as I think that'll be the only way to ensure that it is right throughout the rev range.

Cheers

Mike

Which hole? the idle air jet? On my car, blocking them makes the engine sound brokend and kills the power by a staggering amount. unblocking the holes restored normal service.

I used silicone sealant, that way it was easy to remove.

I have an All-Bikes spec 4-2-1 exhaust (as per Rich Miles' Striker) and have used his settings. They were: -

144 mains
Needles on 3rd notch
Air screws out 3.25 turns.

I've never had to touch it since, except for the occasional carb balancing (once a year)!
