Subject: Re: Dynojet Kit


Hi friends,
>>> I have a question. Has somebody install the Dynojet Kit with K&N Air
>>> filter? How many HP you now have more? What is with the fuel consumtion?
Okay, first of all, there two different versions of the dynojet kit
available, a "wrong" one and a "right" one. (->Manfred knows which kit
number ist the correct one).
You can distinguish the kits by the needle, if the needle has a smooth
"outline" like the original, you have the "wrong" kit. If it goes from thin
to thick all in a sudden, you have the "right" kit.

Both kits contain a setup for original exhaust as well as for "good
aftermarket" exhaust, which basically means open exhaust. All kits tested
with K&N Filter. hp numbers are "rear" wheel numbers.

Wrong kit:
original exhaust: runs too lean in the middle, can't really be fixed with
lifting needle. No hp gain, no difference in fuel consumption. Bike runs
very bad in cold weather.
open exhaust: no chance to get it work (according to Mr. Horvarth, also our
own experience).

Right kit:
original exhaust: runs correct in middle, but a bit too fat in high rpm. hp
gain about 1hp. A bit "better responding to throttle" can also be noticed,
maybe thats because of drilling a little hole in the "underpressure
regulator slider" (uggh, that black plastic thingy where the needle sit on).
See the pages of raymond fels to learn more about that.
Fuel consumption was raised about 1/2 Liter, mostly if you go in high rpm
(abvious).

open exhaust: the kit works good with open exhaust BUT you have to adapt the
kit to your exhaust. Without dynamometer workbench your chances will be very
low. Also, exhausts are very different, even the same exhaust can have very
different results if you cut away a piece (ask Manfred about his "flex"
arrow :-)).
So, with correct setup of the kit AND a good (and VERY open) exhaust you can
expect 3-6hp. Fuel consumption is about 10 Liter per 100km.

Costs: DJ kit is about 100Euro or so. K&N Filter about 50euro. Installation
through proffesional tuner: 200-300 Euro.

Other options (as far as I know):

Raymond Tuning. see homepage of Raymond fels. I don't know, if he has tested
with dynamometer workbench.

Yet another setup with DJ parts for open exhaust: needles from "right" kit,
softer springs (but no drilling holes in this gas thingsbums), 132jets and
making a swiss cheese out of your airbox...unfortunatly, this kit isn't
produced anymore (as far as I know)

Strutzenberger Tuning, see African Queens homepage for options and price.
Exhaust makes "starting helicopter" noise :-))

Sinus "Silent Force" Kit: very new, no EG-ABE. Consists of airbox mod.,
carb. mod. conical exhaust piping and exhaust. Out of the box guaranteed
+5hp. Cost 1.000Euro. Quite legal noise, 7 1/2 liter per 100km going fast, 8
1/2 going mad.
Goal ofthe sinus development: to "kick ass" varaderos :-))))

best regards, Martin
p.s. Personally, I tested Dynojet Kit "wrong" and "right" with open and
original muffler. Currently, I have the Sinus kit installed, a final test
through Ingo and Manfred (the fastest atic's :-)) is still missing.
