Dynojet kits

[taint]

After a startling bit of luck, I've managed to purchase a stage 1/3 Dynojet kit for my '95 D6 from eBay for the measly sum of £23 inc shipping.

Assuming it turns up and is complete, I'll be pretty happy (seller has 100% positive from over 1000 ratings, so I'm pretty confident)

So my next question really is, how difficult are they to fit?

I have Reapers DVD and I've previously had the tank and airbox off. From the looks of things, removing the carbs shouldn't be too difficult, but do I have to do a reasonable amount of carb dismantling to actually fit the new jets?

Similarly, I'm guessing the carbs will need re-balanced once re-fitted?

Is this something that a home mechanic should attempt, or would it be better to get a real mechanic to fit?

Thanks for any opinions.

DJ kits are dead easy to fit - just follow the instructions and you won't go far wrong.
Hopefully you'll get a good setting straight away, can be a bit of a 'mare to set up but you should be fine with the stage 1 jets.
They are easier to fit than the Ivans kits.... but not as good.

And yes, balance the carbs afterwards !

[taint]

Considering an Ivan kit for a '95 D6 is rarer than hen's teeth, I'll stick with the Dynojet kit

I'd been planning on going for the stage one jets, but I'm glad of the secondary opinion ; I figured that the stage 3 jets might be too aggressive. Anyone have any experience of the D6 with the stage 3 jets?

I'm guessing I'll need to go for a K&N filter to get the best out of it; rather than the stock OEM filter I currently have fitted?

Thanks for the confirmation that I'll need to balance the carbs, it's been needing done for a while, with or without the jets. I just don't know anyone with a set of manometers and I resent paying for it when I can get a carbtune pro for £50; just too much of a canny Scot I guess It's probably a worthwhile investment

Thanks again

The kit has arrived and looks perfect.

I'm slightly confused; as there are 4 sets of jets; two options for each stage.

My D6 has the Motad 4-1 Stainless system rather than the original twin exhausts, does this qualify as a 'high flow baffle' or is the Motad considered the same as the OEM?

Thanks

T.

[General Gman]

Same as OEM - they don't flow any more air, and you get no performance gains at all.
I too would be interested to see if anyone had fitted a stage 3 kit to a divvy - to get full effect you need a race can and individual pod filters.
Also a nightmare to get set up properly - especially on short stroke motors cos you lose any bottom end power you ever had.

[Padster]

As the Motad is designed to be used in place of the original with no changes to set up you can assume it is not a high flow baffle.

[taint]

So I suppose the next question is, are there any high flow baffles available for a '95 D6 with 4-1 downpipes? ;D

Not that I have the cash available to fit one

I think the K&N OEM replacement filter will be the limit of my expenditure for the next few months.

Thanks again,

T.

any update? whats the dynojet kits like and are they worth it?

[taint]

I have the kit and it seems genuine, however I've yet to get it fitted.

I'm currently waiting to pick up a Morgan Carbtune www.carbtune.com/ before I start the work; which is looking like a purchase for next month.

I've had my D6 off the road over winter and been getting on with some of the other maintenance.

I'll pick up the K&N Filter later.

I'll update again once I've actually fitted them

This bike is a detuned version of a seriously old motor, put in a commuter bike. Why even bother trying to tune it? If I were going to consider it, I'd start by looking at where the 10bhp that got lost between the XJ600S and the XJ600 Diversion went, and trying to round them back up. Probably by trying to get hold of some XJ600S cams and carbs.

But that's a really big "if".

"If" you want to go faster, get a bandit. If you still want to go faster, get a fazer. If you still want to go faster... etc.

Yes, I am being a bit cynical. But then I treat my Diversion as what it is - a bike that's very cheap and quite comfortable for commuting 200 miles a week on. It wasn't ever meant to be fast, and no amount of persuasion will make it so!

Here's a clue, check the diameters out:

Hi Amorti,

The D6 will only ever be a cheap commuter for me, I have no interest in making it faster; just perhaps improve it's mid-range a little; for accelerating in and out of traffic. Maybe make the engine a bit smoother and efficient; for comfort and fuel economy.

From my point of view, £23 to improve the bike a little is a worthwhile investment. If I'd had to pay full price for the kit then I'd agree it's a waste of money. As for the Carbtune, I wanted one anyway; for regular carb balancing, so no loss there either.

The K&N airfilter (direct OEM replacement) may be a little overkill, but I'm still deciding on whether it's worth it. The D6 felt a lot smoother after replacing the old, oil clogged, filter with a new standard filter, so perhaps the improved airflow of the K&N will make a similar improvement.

I spent more replacing the front and rear shock absorbers (because they were both shot) than I will ever spend on 'tuning'.

I'm planning on keeping this bike for a long time; primarily because it wasn't worth anything to start with and it's not likely to ever be worth selling, so I figure a little bit of investment is worth it for my own comfort.

itl never be a racer but no harm in cheaply trying to get the most from it. I'm just looking to get best mpg/low down performance-response . I enjoy the bike. Thanks for info about carb

I would say that the Ivans kit is just as easy to fit as any other kit and even easier as it is plug and play so no dyno time needed, after all 4 jets and 4 needles to change which ever make is still 4 jets and 4 needles to change.

The only time Ivans kits get more difficult is when you go the hole hog and do all of what Ivan recommends, this is not compulsory though. I have fitted over 20 kits to Fazers and done from just a straight jet kit fit to whats known as the full Monty and they all work 1st time and need no tweaking.

As with Ivans SO and MB kits Dyna-jets stage 1 and stage 3 are very different animals and will need as Gman points out a good quality end can if not a full system and I`m not sure one is made for the Divvy 6

A K&N filter as a direct replacement should flow better than the paper element original. I'd also expect the airbox has an effect - sports bikes all use the same type of setup. I'd go for the mid range jet kit and see how it turns out, but if you have the small carbs see if you can get the 600S type as shown by Amorti.

reaper how much are the ivan kits for the fazer and how difficult are they to fit/setup carbs to get the best. i already have k&n air filter and an fuel can. so all i really want now is the jets doing. do they improve mpg? are the thundercat ivan kits different to the fazer ivan kits as the are mostly the same engine. help and advice much appreciated. also how do i go about balancing my carbs on the fazer

dan

[taint]

The jet kit is now installed and the carbs balanced. I also opted for the K&N air filter. I still have to work out some other kinks in the system, but I'll update again once I've managed to road test.

Dan, you can find out more info and prices for the Ivan kits here: www.ivansperformanceproducts.com

I think they may only sell directly, but I could easily be wrong. There's a fairly small number of kits offered but they list detailed information specific for each bike. I doubt the kits will work across models, no matter how similar the engines are; as Ivan prides himself on tailoring the setup specifically to the model. Dynojet kits are not as highly tuned.

If the base Ivan kit is as easy as the Dynojet kit for the diversion, it should be easy to fit. I think it'll be down to how much extra work you want to put in perfecting your set up.

Theoretically you should see an improvement in the MPG; as you're getting more power out of the same engine; therefore making more efficient use of the power.

No idea how to balance the carbs on a Fazer, but I would assume it's pretty similar to the diversion. One of the Fazer owners may be able to shine more light on the subject.

been in touch with the ivan kit distributer today and informed by another member that they never made a kit for the fazer or for the thundercat but i will keep lookin for that cheap dynojet kit and stage 2 the bike i think ive got a fuel end can and k&n filters. so shud be easy (fingers crossed)
