Dynojet kits?

Looking around these look like an American company, anybody know where I can get a stage 2 kit in the UK and do they make a noticeable difference?

When I changed the exhaust and air filter on my 893 blade engine it had horrible flat spots, stage II dynojet kit sorted it out.

Ah that's good to know thanks was it a stage 2, where did you buy the kit? Was it easy to fit?

I would personally go for a Factory Pro jet kit over Dynojet. Factory Pro use the same labelling convention on their jets as the carb manufacturers do, but for some inexplicable reason Dynojet decided to use their own numbers so you can't compare them with standard jets if you want to adjust the fuelling.

Dynojet settings - pretty much ballpark as follows -

132 main jets
pilots turned out 21/4 turns
FLTV50 needles with circlip on #2 groove from top
Half shims not used
Heavy duty lift springs
Do not drill slide lifts as per instructions
We can supply a dedicated kit if you need one as the stock kit is aimed at bike and has wrong jets and needles in
Hope that helps

On mine (Fireblade 919) I have 130 main jets. Could be good or you suggest anyway to change them for 132?
How can I recognise if I have Heavy duty lift springs?
All other specification are according to your suggested setting

In general 132 jets will work with our forced induction airbox or a pipercross panel filter, if using a stock airbox with performance filter 130 will work better, stock airbox and stock filter usually sees mains down to 128 - the heavy duty liftt springs are a very course open wound affair whereas the stock ones are longer and very close wound
hope that helps

I'm pretty simple when it comes to bike engines.
I have the Yamaha fazer fzs 1000 engine 142 bhp I believe.
I am looking at getting ram air individual filters and it also has a four into one exhaust already
Which kit do I need and how much is it going to cost me?

Also is it a case of fitting the new jets and rebalancing the carbs or is it a full set up by bike Specialest or rolling road?
