I am thinking about installing an Ivans Jet Kit....anyone got any info on these

Cheers...do you have one fitted

Mike on this forum is very up to speed on ivans jet kits :) he has fitted most of the ones you will find in the uk :P
I brought my bike with a Dynojet kit fitted and wasnt happy with the low down feel and midrange. although top end was great.
After talking with others on here and with mike i decided to try the ivans full monty.
WOW so much better feel and rideability. the midrange is greatly improved and on dyno runs (had 3 done over the years) the air/fuel ratio has been great and the power curve smooth with no dips.
-
I also had mine dyno'd resulting in power at 128bhp and running extremely rich. I was told to install the standard kit by my mechanic as he couldnt see any real advantage to porting the rubbers etc as it wold generate any more power for a hell of lot more work.

Extremely rich at all throttle/rpm combinations or just at full throttle? It's usually the latter. Ivan's kits get the air/fuel ratio right across the board. :)
Show this (http://www.yamahafz1oa.com/forum/showthread.php?t=49856&highlight=intake+boot+mods) to your mechanic and see what he says. Porting the intake stubs takes me 20 - 30 mins. The airbox lid mod is a 10 minute job.

Full monty on mine, dyno run short time later, air fuel ratio near spot on according to dyno man. :)

Mine has a standard kit fitted by Mike and a 4 degree advancer, love it! and Maxton kit back and front, no point having the power (and smoothness) and then tying the suspension in knots!
-

oh yes! :D
SO kit, modded intakes and airbox modded. for me the biggest noticeable difference is the low rpm pickup in top gear.

The other thing to remember is the ivans kit is not all about BIG bhp. the Dyno jet kit produces a couple more horses but destroys the midrange and low end to do it.
lets face it most of the work a 1000cc gets is in the mid range.
either the SO kit or the full monty will greatly improve an allready good motor, i just didnt see the point in doing half measures. a lot of research went in to the ivans kit to produce the best all round motor and i think all will agree that have had it done, it was time well spent.
-
Does anyone really think the full monty will be the best option for me over the standard, I have an after market mercury can but I may be thinking my mechanic cant be arsed with the porting
-
If you want the porting you could do it yourself, or buy ported boots or see if Mike can fit you into his hectic schedule.
Or just go with the SO kit.
-
I dispute the suggestion that the Dynojerk kit produces more peak bhp than either of Ivan's kits. It's certainly true Ivan's is way better throughout the rev range, though. :)
Full Monty or Slip-On kit? Both produce similar power curves and throttle response up to 8k rpm. The extra kick of the Full Monty comes in at that point. If you don't routinely use the throttle hard to exploit the high end of the rev band then the Slip On kit will be fine.
If your mechanic can't be bothered to port the intakes, beware. Most of the unsatisfactory Ivan's installations are done by professional mechanics who can't be bothered to do the carb work thoroughly, either. Or else they think they know better than Ivan and skip stages because they don't think they're necessary.
-
I dont have BHP charts to show the dyno jet curve, wish i had done it before i got the ivans jet kit fitted.
But the dynokit certainly "felt" with butt dyno quicker at the high revs. now this could be down to lots of thing, mostly down to how god awfull it was untill 7k+ when everything kicked in giving it that feel.
but also didnt ivan run a comparison and the dynojet kit had an extra few bhp? thought i had seen that when i looked in to getting the kit all those years ago.
but i could be wrong and will allways bow to you with anything ivans related lol
realy affter i had the kit fitted i wanted to have a little doll of mike on the tank so i could prey and give thx to the god of ivans :lol :b
-
I had a 96 CBR 1000F before the Fazer and the Fazer felt really gutless low down compared with the CBR (CBR is a lot heavier as well) but after that God also known as Mike fitted the full monty it changed the bike completely in my opinion and I love it now.
I too couldn't see the point of fitting the SO kit so went for the MO plus Mike did it in a 1/4 of the time it would have taken me, I think the cost of the kit and fitting was more than reasonable.
-
Which Mike do I contact as there is quite a few on here
-
Falcon 269 is that Mike
-
Thanks...Id hate to fit the wrong one and regret it later

Ive had seven fazer 1000's now, 4 have been stock, one had a dynojet kit fitted & two of them were fitted with the ivans kits (one S.O & one Full Monty)
The dynojet kitted bike was awful as all the power came in very high in the rev range and at low rpm/throttle it was an absolute pig to ride & bogged down all the time.
Unfortunately I never rode the ivans kitted bikes back to back, but from memory I could'nt really tell the difference :\ Other than that they BOTH rode better than stock.
I honestly could'nt imagine riding one of these now without having an ivans kit fitted as it really does transform the bikes tractability, and as an added bonus it will also reduce fuel consumption too, so win win really :D
-
A quick qn re this subject: what is the difference between the 2 kits? (the full one and the slip on one) I have read the instructions for the full one and they seem quite involved!! Is the slip on one any easier to fit?? As per Mike's post above I seldom find the need to exceed 8000 rpm so the slip on would seem the better option if easier to fit.
As usual any advice welcome lads and lasses :)

The mechanics of fitting either of Ivan's kits to the carbs are identical.
What sets the Full Monty apart is modifications to the intake stubs between carbs and cylinder head, and alterations to the airbox lid to work best with a K&N filter.

what is done to the inlet stubs to modify them?

Having just given mine the full monty I would definitely recommend it :woot :thumbup

My own experience is that , The jet kit is essential to get a thou running right with an after market can fitted!But my bike was running smoothly before the mod and apart from the better starting I would not have bothered .The fuel consumption has increased slightly and the power delivery is more aggressive ,probably good for a younger owners
but I don't like it. The kit is expensive by any standards.
thats my two penneth, sure to upset everyone !
-
Sorry, I can't agree that it's expensive to get a bike running a whole lot better. Mine is an '04 bike that had just over 6,000 miles on it at the time of conversion, and I only had the "slip-on" version as I still run the standard can, and am delighted with the improvement. I DON'T ride this way, but it will pull 20 mph in 6th gear without ANY complaint.
-
Mine runs fine with an aftermarket can without the jet kit. I'm looking forward to a bit more oomph with it fitted though.
-
The term a whole lot better is subjective!( As is expensive). Mine was smooth vibration free and progressive. That was good for me!
When I fiitted an after market can "before mod" it killed the mid range ! .Certainly more power when Ivanised . If that's your requirement go for it . you pays yer money Etc !
Just as an after thought , I don't see why you could not do a cheepo carb mod , ie the drilling and clip carb springs, float levels, air box , carb rubbers, richen mixture ,but leave the needles and jets alone, the first part I would think would ensure a quicker take off, I'm sure someone will say it a bad idea . But has it been done that way?
-
I have joined the ranks as I am now Ivanised with 135BHP at the back wheel....awesome improvement.......just need some decent weather to do some full testing
-
Why didnt you just refit the standard can if it was running smoothly. If you consider the jet kit expensive against your mod that killed the midrange,the aftermarket can, it must be a really cheap crap can.
I would not describe the power delivery as more aggressive, rather fuller and more linear without the dips through the midrange when standard. Not sure whats not to like. :\
-
The can I fitted was a quill t3 ! It killed the midrange on the thou , Just as the viper can did the same on the 600. The standard can weighs a ton and looks and sounds crap.
I did the ivan mod ,because i read all the hype and "old adage "it seemed a good idea at the time!
-
Think I know where you're coming from bwizz. My bike lost a bit of grunt at very low revs with the Ivans kit fitted. Top end power is the obvious improvement & it is easier to start now. Think I might have been better off with the slip on kit for my bike as I did enjoy the low down pull.
-
140 at the back wheel? Great result SilverFZ!

Hi Guys
Just bought a 1000 thats stood and has a bit of a misfire, I'm guessing stale fuel and a bit of crud in the carbs, if I'm taking the carbs off I may as well ivanise them at the same time but will have the standard can on for a while, any issues with this setup?
I will probably go full monty rather than SO kit, can will be changed eventually.
