What is Ivanising?

[jonjenk]

Someone on here suggested I "Ivanise" my fazer1000. ... can anyone explain what this is, who does it and how much. Cheers.

Sorry to be a tease! Here's the web page

The kit costs around £120 and makes a Fazer 1000 even better than it already is. Crisper throttle response, less surging on a steady throttle, smoother torque curve and the rear wheel horsepower goes from 120 to 140. Not that I did it for the top end power increase, it was more about making it more rideable. If you do a search on this forum you'll find 8 pages of glowing reports

It takes about 4 hours to fit but there's a chap on here called Falcon who has fitted hundreds who pops over from Spain every now and then.

Don't worry about reading all that  :z
Just look at the last line in the last post here http://foc-u.co.uk/index.php/topic,5911.0.html
It looks like Mike will be over here soon working his magic, the only problem is, once you know when he is coming, is the waiting.
Get in on one of his visits, you wont regret it.. I did 10 years ago and the old girl has never missed a beat since, still running sweet and pulling  strong after all those years.

Hi JonJenk,

Drop me an e-mail (mikegreatorexAThotmail.com) and I'll give you chapter and verse on 'Ivanising'.

And yes, still thinking of a May visit ... must get started on the planning of that soon.

How do you know if it has been done already?

How do you know if it has been done already?

I 2nd that.. mine seems to be fairly smooth anyway. It has also had a few mods by the previous owner so is there an easy way to spot if it has already been done?

[kebab19]

Probably several ways, but I noticed that after fitting my kit the amount of revs while starting on full choke dropped by quite a bit - from memory she now sits under 2500rpm instead of 3000+ she used to run at

Then again, perhaps I didn't fit the kit properly :-D

[Falcon 269]

Quickest way to check is to remove one of the carb tops (#2 is easiest) and then take out the throttle slide and inspect the needle.

If it has SD-129 or SD-130 stamped around the top, it's a standard original needle.

Ivan's needles have 5 different taper angles ground into them, two of which are obvious to the naked eye.

[bigbluebear]

Any idea of the jet part numbers

[Falcon 269]

Jets are marked 130 and 132.5.  Mikuni standard parts. 

You can't get at the jets without removing the carbs, which is why I suggested the needles as the quickest check.

[bigbluebear]

Thanks Mike, not that I don't trust my mechanic but checked the old needles and they were SD-130 but looked at the jets and they were two different part numbers, I thought he maybe forgot to replace two of them. I did some checking with SG Motorsports and Ivans are 122.5 for the four of them.....anyone know why the old jets are two different sized and Ivans are all the same.

Quite common with Yamaha running richer outside carbs. The old fzr4 3tj ran 1 size down on the middle cylinders. Apparently the middle cylinders run hotter. All the dyno operators told us to run 4 of a kind as at 16k rpm you dont want dodgy fuelling

16k rpm on a fazer.......my clocks only go up to 13k. :'( if it reached 16k rpm I'd expect more than dodgy fuelling :lol

Is it really worth the £110 price tag? http://www.sgmotorsport.co.uk/index.php?...ucts_id=44

Going to check mine over the weekend to see if it has been done or not. I hope it has that way I can put the money towards a Multiguage

[sadlonelygit]

yes

[AyJay]

Yes x2


The best £110 you'll ever spend on a bike.

[Falcon 269]

Exactly as SLG called it ... your mechanic hasn't screwed up.

And yes, definitely worth it ...

[ghostbiker]

When I got mine someone had put a dyno kit on it. Ran like a bag of nails till.6k ish then off like a cat affter a rat. Hated the way it behaved.
Then mike worked his magic and was a huge improvement. So clean from low down to red line.
Had it on a dyno run a couple of times now and each time they comment on how good the fueling is.

2nd best money you can spend on the gen 1. (first being suspension)

[FuZzBoM]

Ok well you have convinced me.. so much so I got lucky on the bay this evening. http://www.ebay.co.uk/itm/IVANS-CARB-TUN...true&rt=nc



I have had a read through the various guides and I think I am capable of doing the work myself. however if anyone has any pearls of wisdom feel free to pass them on. I am in no rush as the bike is not my primary mode of transport but having it sorted for the better weather is my goal.

Apologies to jonjenk it was far from my intention to hijack your thread chap.

[Tulumbe]

Sorry if I'd missed it, but how the fuel consumption is reflected on bike Ivanised, is there any change?
