Dynojet Kit Stage 1 vs Rejetting @ Dyno Place
 

I know pleanty of threads about the dynojet kit already but they don't answer my questions...

What advantage / disadvantage is the Dynijet Kit vs the rejetting at a dyno place ?

I have a K&N & a Remus GP.

I might be able get the stage 1 kit cheap. My local dyno place quoted me £140+vat for a rejet.

where's the dynojet kits cost around £80.

Anyone? WHat's better getting it rejetted at a Dyno place or buy the Stage 1 kit ?

(Need to know asap as someone els might buy the Stage 1 kit...)

My opinion, frankly, is that the Stage 1 DJ kit is utter junk- you get very little and in my experience the directions are poor- the suggested setting were all done for the old K&N, it seems. But at the same time, that price for the dyno work is pretty steep.

K thanks I won't bother then :lol:

I think 21Quest would disagree though, to be fair ;) But I reckon you can get 9/10 or more of the benefit with a couple of jets (at £3 a pair from PDQ) and possibly either moving the needle clip or putting a thin washer in to raise it a half step.

You completely lost me.

Too much tech talk :lol:

Take little bits out, put bigger bits in :)

I've never understood the principle behind the Dynojet kits, its like tuning a guitar using a book to tell you how many turns of the machine head! It might run better but its a thousand to one that its going to run perfect.

Even two bikes set up the same can end up up two different carb/PC settings to get the right air/fuel across the range of revs and throttle positions, not to mention run with optimised power (not usually stochiometric ratios).

The ONLY way to get a bike set up right and know its right is on the track with data logging on board or (for the rest of us!) on the dyno/rolling road.

Sound like you were already making the right decision tho!

PS in my experience £140 for an afternoon on the dyno sounds pretty heavy, can you shop about?

Top metaphor action there. The other way to do it, is with a finely tuned ****. You'll probably never get it 100%, but you can get it within spitting distance with enough practice and trial and error. Mine's off to YPE next thursday, we'll see how badly wrong I've got it then :) I'm thinking that quote includes a DJ or Factory kit, if not then I'd agree it's too steep.

So also a bit like setting up a guitar I suppose, in that you can tune by ear and get a fair result, but if you want perfect intonation you'll want a quality tuner.
