DCPR8EIX is the correct NGK iridium type plug for the 2002 fe 400.
IXU24 is the Denso brand iridium plug number.
I would use the plug that was designed for the engine rather than try what might work.

Regarding twin electrode spark plugs:
I have been using EK series spark plugs in early Husaberg engines since roughly 1995. The primary reason being the same as that of using a precious alloy model "ie a potential reduction of misfire with the consequent likelihood of improved starting and enhanced low RPM performance."
For the record:
To Date the fine wire, multi or slotted electrode spark plugs have yet to register a quantifiable power improvement during dynamometer testing.
Kind Regards,
Dale

Hello Dale.Thanks for the info on the ek plugs,I will have one in my 99 fe400 next ride. The canadian motorcycle monthly "Inside Motorcycles"just published a comparision test on the new crop of motocross machines.Unfortunatly the FC450 supplied by BMG got a lackluster report.It suggested that this machine suffered from poor starting and lack of power.Being a Yamaha and a Suzuki dealer for many years I know that the machines offered for testing by the Japanese makers are carefully prepped before being offered to the magazines for testing and very often service reps accompany the machines to the test.To get to the point,is this a service that you can provide?If so, Please call BMG with your rates for a proper set up and road test support. They need you...nsman

Hi newsman,
Thank you for the vote of confidence.
For the record:
Over the past one and one half years I have repeatedly offered my services to BMG. Prior to BMG said services were always made available to Husaberg Sweden and KTM Austria / USA.
For your review:

As the old saying goes "You may lead a horse to water though you cannot make him drink".

Hi Newsman,
I am quite certain such is the result of an initial "Dollar Investment Bottom Line". From a business perspective I suppose one must speculate on where best to invest. In the case of BMG it is of my opinion that they have invested most all of their available resources into product inventory. As an engineer (not a businessman) my opinions regarding marketing are quite likely far removed from what is truly best regarding unit distribution and profit margin.
For the record:
It is of my personal opinion that BMG has delivered far beyond expectation regarding product availability and distributor interaction. If and when the time comes that funds are made readily available for more technically oriented ventures I hope to once again be an integral component.
Time shall tell.
Happy Holidays,
Sincerely,
Dale

Hi Faktor,
Either the NGK or ND Iridium plug will suffice.
One has proven to be no better / no worse than the other.

Dale

Since I am still waiting for some spare parts from Husaberg I amused my self with reading the review posted above. In the tests made in Europe Husaberg is in the bottom of the list as well. I believe there will be a new test in the beginning of January as the last three years. BMG I don’t know anything about but I don’t believe they deliver the bikes for the European tests.
However, this question is perhaps a little controversially. Since the KTM 525 engine and the Husaberg 501 engine are very similar, why does the KTM feel easier to handle?

Where ever we park the motorhome, USA
Part of the answer is the frame and the steering geometry. The Husabergs are much more stabile at higher speeds, especially in the sand washes and on hardpack trails that have loose pebbles on top.
The 525 engine diagram shows 2 counterbalancers that are running at a lower rpm compared to the Husaberg counterbalancer. The KTM counterbalancers have larger gears on the counterbalancers and a smaller gear drives them, therefore they would be spinning at a lower rpm, relatively. Since enertia is a product of mass X the square of the velocity, the Husaberg design will have more enertia effect. Double your rpm = 4 times the enertia = more gyroscopic effect.
I found that if I make a conscious, deliberate effort to toss the bike sideways when leaning in the turns, I can consistantly get the bike to lean better and the gyroscopic effect seems to help keep the bike stabile in the turn after the bike is leaning.
The Husaberg bikes, in my opinion, perform better at higher speeds. The bike is designed to be ridden fast. The bike is not designed for very slow, technical trails.
Yesterday, while riding, this was reconfirmed. When negotiating 1st and 2nd gear turns, my son on his KTM literally left me in his dust. But when we were in the higher speed sections, 3rd gear turns, we were about equal, and in 4th to 5th gear turns, the Husaberg turned better. The Husaberg was able to go faster throught the turns and exit at a higher speed.

Spark Plugs. Little things that come in standard materials or some exotic metal (Irradium, Gold Palladium, Platinum) and who knows what next. The exotic metals stand up better so the tip can be made finer and still give good service life. The Small tip is supposedly easier to fire. Changing from standard to exotic will only hurt your wallet. Engine is all fine. All the older engines use a 10mm thread (CR7E) and the new engines 12mm. The new engine plugs are weird as they have 12mm threads (the D prefix) yet use the small 5/8 socket (the C Prefix) DCPR8E. These buggers for the new engine are hard to find at local Jap bike/independent shops so having a spare is a good idea.

already try today my bike(fe501) with the ngk iridium.the bike starts easier cold and hot.
the idle was way too high and after i set it the bike ran ok!!! but if i rev it the idle doesnt come down :?: it stays very high for 30 seconds and then suddenly drops....is there any chance that is the plug doing this?
HELP HERE :?: :?: :?:

Hi alex,does not sound like a spark plug issue to me.If you removed your fuel tank to get better access to your spark plug there is a chance that the throttle cable may have been moved and is now kinked or twisted and is causing a binding in the cable.Sounds like the carb slide is not returning smoothly in the carb.An air leak also can cause the symptoms you describe but I assume this just started after the installation of the new plug..is this correct?...nsman

hello, well before the instalation of the new plug it already had this problem but now is more pronounced.
already check the cable ,and its ok no bindings ...
maybe it was just coincidence and this as nothing to do with the iridium plug.... :?: :?: :?:
tell me more about the air leak :?:
or more options to correct this annoying problem :evil:
thanks

alex,if you have air leak your idle speed will be unstable as you describe.Normally,you have a crack in the intake manifold(rubber between the carb and cylinder head),if you do not find one(spray wd-40 on the rubber while its running to determine if the idle speed momentarily becomes stable) ,then the most likely cause is you have one or more of your engine valves with not enough clearance.If your engine has been operated for even a short time without enough valve to rocker clearance then it is very probable that you have a leaking (burnt) valve(which is still an air leak).Have your motor checked by a competent tech and ask for a leak down test as well as a compression test,he/she can tell by the results what your engines valve condition is.hope this helps....nsman
