Re jetting

[scott02464]

Yeah I think that's the way forward for me mate. I actually rang the dyno centre in Malton this morning which is my closest.
He said it would be £25 to put it on the dyno for a readout and £40 per hour if I let him tinker with it.

But I think I'll go for the readout then tinker myself, can't afford £40 per hour :-(

Well had a crack at it to day again,


Got the TPS dead on 500

Mixture set at 2 turns front and 2 & 1/8 at the rear

Put the 50 pilot Jets in place of the 48's

Moved the Needles onto the 5th clip from the 4th

Same 190 Dynojet mains


Took it for a ride, bike feels super smooth now but its defo a little rich at the idle to off idle throttle so might have a try at backing the mixture's in slightly but over all much smoother power and a very ridable bike, certainly isn't dangerously lean like last time and doesn't have the I'm about to melt into the ground smell

£40 an hour is quite reasonable, if he knows what he's doing around Storms.
Ask him for a couple of readout charts form previous ones he's done.

Will do mate ;-)

I'm going to try and book it in this Wednesday!

Shall I post a pic of the readout on here to see what you lads think?

I must admit tho I went to work on it today as always (no fast roads tho) and I have to say it feels very responsive and feels like it wants to go!
I just want to make sure it's the best it can be. stoichiometric wise.

Pic and pic :-)

Will do, wish it was tomorrow now lol

They are massive mains come to think of it Seb! On the chart it works out at 205 Keihin size!!

yeh they are big but i have that pipercross and yoshi set up, its pullig very strong up top just the bottom that needs tweaking now, i thinks...

my idle was fluctuating so need to sort that out

[scott02464]

Iv got the bike booked in on the Dyno way hey!

Thursday 17:00 so I'll be posting a pic of the results as I bet at least Carl will be interested to see what's happened! :-)

Wish it was tomorrow

[VTRDark]

Yep I will be interested. I want to get a run on a dyno for mine one weekend, see how far out mine is on the AF. I will then have to re adjust things no doubt. I'm going to put the 48 pilots back in mine. the 50's are just a little too big. A lot of people on the Hawk site say Factory Pro was wrong on that one. Me being the stubborn git I am, refused to listen, thinking to myself Factory pro must no what they are doing. There's got to be a reason for it. I might email Mark at factory and ask him out of curiosity. Just seems strange because they used to supply the 48's

Lets hope they can get yours sorted with shimming the needles otherwise they will be charging you for a jet kit as well. Did you ask them if they have experience with the storms.?

(:-})

[scott02464]

Yeah mine has the 48s in mate but they were already in for some reason....

It does feel strong (the bike) so if it's set up wrong (proberly is know knowing my luck) I'd like to feel how good a properly set up one is lol

[VTRDark]

This may explain the reason for 48's http://www.vtr1000.org/phpBB3/viewtopic ... 32#p114511

[scott02464]

Oh nice1 Carl, so at least mine are standard and no one else has be tinkering with my belovered! Lol

[seb421]

Arghh bloody hell

well other day i did the jets,

now its running silky silky smooth in the mid range, then has a little bit of a soft patch in the middle before picking backup again,

The 50 pilot jets have made it fantastic at the bottom end, mixture two turns out and two and a 1/8th at the back. might even them out tho on the next fiddle

now i know i shouldn't have done two things at once but i took a gamble,

wonder if i go back one clip on the needle to lean them it might sort that middle out, i changed them from the 4th to the 5th clip at the same time as putting in the 50's

still feels good at the top end just a little soft spot in the middle of the throttle range when accelerating say coming onto a motorway you can notice it.

Was going to take it to rocket centre but cant be arsed paying / getting robbed for time as they want the bike the day before so i wont be there to see how many runs they have done and charging me etc

would ryther be there to observe what's going on.

When ive been paid again i wil take it some where with an A/F read out might try that Quill exhausts in Manchester as they have a dyno

for the time being tho its not overheating so that's a plus

just need to sort out what feels like a bit to rich at idle to off idle and that weak spot in the middle

[VTRDark]

The only way you are going to know is to try it. I ended up moving a clip position on mine and thought that maybe it was a bit much and wanted something in between, so I ended up shimming the rear carb to richen a tad more than the front. The principle behind it with Hawks write up and the rear being shimmed more than the front. Sounds like your getting there. I think in your case with the full system the 50's is the right move. I'm going back down to the 48's on mine. It's just a little to rich and too hard to get the mixture spot on.

I don't know what revs you where at where the flat spot is. You say the middle so I presume about 7 thou which is right at the top of the needle circuit, so your mains are on they way to being full on. Sounds like your in that overlap zone where it's switching circuits. What mains have you got in. It may be worth considering dropping one size on one of the carbs. It's a quick easy check compared to adjusting needles.

But then there's a little voice in my head saying no. The mains are good so leave alone. Get the needle heights right and then move onto the pilot. Which is the way Factory Pro say to tune CV Carbs. Start at the top and work you way down.

A black-art, black art-indeed. It's not always that straight forward. I would love to have my own dyno. Don't Halfords sell them. Gunsen dyno tune
