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 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!

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.

bigbluebear · « **Reply #10 on:** 17 May 2012, 08:51:41 pm »

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

mcyoungy · « **Reply #11 on:** 17 May 2012, 08:53:33 pm »

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

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.

bigbluebear · « **Reply #15 on:** 18 May 2012, 11:03:26 am »

Which Mike do I contact as there is quite a few on here

mcyoungy · « **Reply #16 on:** 18 May 2012, 11:09:00 am »

Falcon 269 is that Mike

bigbluebear · « **Reply #17 on:** 18 May 2012, 11:14:10 am »

Thanks...Id hate to fit the wrong one and regret it later

chitsu · « **Reply #18 on:** 18 May 2012, 06:06:53 pm »

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

tomlinscote · « **Reply #19 on:** 18 May 2012, 07:13:16 pm »

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
