US Dynojet kit.

once again steve the point is well put across, and i agree intirely perhaps you could be my proof reader lol

i will admit that the ability with the written word is not my best assett as i am partially dyslexic.

i have a open mind to all opinion whether it be informed or not and in the flesh can be somewhat blunt in my opinion.

and will openly admit whilst i am a normally chilled out type person and open to any amount of piss taking, the mdj chap did get under my skin.

apologies to anyone who may have been offended.

and i future i will consider my answers more carefully in the way i put them across.

perhaps i should employ you as my editor

although i make no apology for the essence of my post and stand by all that i tried to put across.

i have no personal dispute with mdj except for his unnessessary attack on my person, and rudeness. and would suggest that had he spoken to me or many other people on here in that way in person he would still be recovering.

points well put steve, cheers

[belerathon]

sorry ben agreed mate, absolutely

[steve trow]

See.... like i said about eastenders.... they all lived happily ever after

Looks like im up Llangollen on me todd then

[belerathon]

Steve......whats eastenders???

[petrolhead]

belerathon.

You say in one of your posts that you have set up the engine well. Could you please describe what you have done in detail?

Thank you.

[belerathon]

hi petrol,

well i'll give it a go, might take me a while, better with my hands and head than words.
bear with me if you dont mind.

So does all this mean that no one Knows why the U.S is different than the European one.
It's obvious (even to me) that some like em and some don't but what I was comming to was the different size of jets front/rear and was there a little more umph we could squeeze out of my old girl.( and yes I do mean the Firestorm )

Flippin 'eck! Conufused? You will be!
This is a subject close to me heart @ the mo'
Got a set of G-Force carbon race cans, low level, top condition, 6 months use, for the bargin price of notes the pair. Sound brill, but reading info from various sources, including this workshop, it would seem that the bike needs to have some work on the fuelling as they tend to run lean.
So at the risk of huge embarrassment without too much in the way of tecnical info, can take in some basic info is it worth spending the dosh + getting it set up on a dyno?, or taking it to a specialist who can play around with the jetting. Not too interested in more BHP just the bike running correctly.
Am totally willing to have the p*ss taken for asking such a stupid question !!!!!!!!!!!!!

[Pete.L]

Hi Robbie.
Not a stupid question at all. No one wants to burn out there valves running too lean.
Are you having a problem with the bike now? i.e lots of popping on the over run. Not accelerating or cruising smoothly?
If you are worried at all you should just have a diagnostic run on a dyno. My local bloke only charges 30 quid and then gives loads of free advise.
If the G-force cans are direct replacements they may not require a jet kit. Tell us some more details.

Hi Pete,
I'm new to Storms, having got mine in March this year.
The bike is accelerating and crusing smoothly, or not a noticeable difference from the standard cans, crusing seems to be 80+ on a Storm though.
There is some popping from the exhaust on the overrun.
Having got the cans seconhand, I will contact G-Force this week to ascertain what they say regarding the direct replacement.
Petrolhead + MJD give info in earlier posts regarding the settings for Main jets etc. and I was also wondering if it is possible to take these settings, apply them to the bike without running on a Dyno.
Also viewing a Dyno on another site, it seems that the fuel/air mix is way out below 6-7000RPM, above that it appears to run flat and true with minimal distortion on the graph, although the bike was a couple of years old, if that makes any difference.
I have however spoken to Stockport Motorcycle Centre, nearest Dyno to home, 25 squid + the dreaded VAT for a couple of runs and should be able to give some comparisons with previous runs using G-Force cans.
Now wondering if to run the bike with the cans on or not until have had a Dyno run. Not sure how long it would take to burn the vales out, ouch!
Unfortunatly cash at the moment is at a premium, eldest Daughter gets married next year, in Cyprus to boot, so not only a Wedding to cough up for, 2 weeks jollies as well. Kids U just can't trust them can U.

Hi Orange Robbie.
You Said

Good Idea. You don't have to have it set up on a dyno. If they can tell you the main jet sizes,the needle height and approximate number of turns to open the mixture screws from fully closed you should be able to get a pretty close set up. Don't know how long it would take to burn the valves out, it dependes how lean you are running. I blew an exhuast gasket out on my old 250 years ago on the way to Blackpool and by the time I had returned I had to do the last 50 miles on one cylinder no exhaust valves
See what G-force Says, What have you got too loose. Also there is a Bloke I see some mornings who has the same pipes as you if the oppertunity arises I'll ask him if he knows what his settings are

Hi Pete,
Had a word with G-Force yesterday, the first question they ask is "have you changed the air filter?".
It would seem that although the addition of race cans leans the mixture to a degree, it is not to the point where it will damage the valves if you retain the OE air filter.
Only when a free flow filter is added will it lean the mixture to the extent of risking damage to the valves. At this point they would advise that the bike is given a Dyno run to ascertain the adjustments required to correct the mixture. As the guy at G-Force said, you can run a Dyno with OE air filter to squeeze out a more performance.
Me I just fancied a bit more noise. so that clears it up, will leave as is, which brings us back to the question, would you have your bike fitted with a Dynojet Kit O.K only joking.
The only other question that crosses my mind is, if fitting a free flow air filter with standard cans, will this have the same effect as fillting a free flow air filter with race cans. Petrolhead has done this judging from an earlier post, so is he having any problems?

[Pete.L]

He He

would you have your bike fitted with a Dynojet Kit

It is

if fitting a free flow air filter with standard cans, will this have the same effect as fillting a free flow air filter with race cans

Oh yes

Fitting a K&N filter with std cans was the first thing I did at Its first service. I hoped to save a little money in the long run(100,000 mile user life) and thought it would improve the proformance. All it did was give me a stumble in the power curve between 4&5k rpm.
Then I added a jet kit to get rid of the stumble.(wasn't signed on here then so I didn,t know to pack the needles with a 0.7mm washer ) still on std cans. Small inprovement but overall in my opinion nt worth the expence.
Then Last year I changed the std pipes for some Laser Duo Techs and started adjusting jets and needles all over again

Pete.l
Maybe I should have signed on as Twidler?
Hmmm. Whats this do ?..........Doh!

[Orange Robbie]

Hi Pete.
Thanx for the answers to the queries, very helpful.
Interesting your last post regarding the fitting of a free flow air filter , you would have thought that by making the engine breathe a bit easier that any holes in the power curve would have dissapeared.
Going off on a tangent here, is it me been a total mechanical juggler, or is it that Vee twins are more affected by tuning / twiddling than a multi cylinder on the basis that the overall effect on a Vee twin is multiplied by a factor of 2 over a four cylinder? or should we all rush out and buy the new Strom when it appears, complete with fuel injection, and any tuning can be compensated for by the purchase of a new chip, and problem solved.
Bugger this could go on forever, forget I said it, or should a new forum titled, "All sh*te about Storms" be opened.

[Pete.L]

Hi Robbie
you asked

you would have thought that by making the engine breathe a bit easier that any holes in the power curve would have dissapeared.

Not really. You have to take into consideration that as the revs increase the ignition timing advances at the same time and on some bike a certain amount of cam overlap is built into them to increase bottom end torque also the carbs normally have 3 stages of fueling (tick over uses pilot jets,mid range uses needle(don't get me started on needle profiles, and top end uses main jets...simplified version) all these stages have to varying degrees affects on each other as well. Honda have probaly spent a lot of time trying to get them all into ballance with each other and then fine tuning it all together by working out an electronic ignition map which will adjust the firing times to smooth any rough edges.
Changing one tiny thing ie the amount of air flow passing through, can upset this balance and remove the silky smooth power curves we are so used to on modern bikes.

Then you asked

is it me been a total mechanical juggler, or is it that Vee twins are more affected by tuning

This is the first one I've played with so I've not much to compair with but I can honestly say I've had to do more farting around with the twin than any multi-cylinder I've messed with.

should we all rush out and buy the new Strom when it appears, complete with fuel injection, and any tuning can be compensated for by the purchase of a new chip, and problem solved

Guess who's saving his pennies
