Help Calling all UK WR450 Owners!!
Posted November 09, 2006 - 11:45 AM
2,Air box opened up
3,Grey wire disconnected
4,YZ throttle stop
The bike came fitted with a 45 PILOT,165 MAIN and a non adjustable Needle .In the spares bag it had a YZ Throttle stop and a 48 PILOT which i have fitted and an adjustable Needle which i fitted with the circlip on the 5th notch (from what i see on this site this is what most people have it on) But what i would like to know is what MAIN JET most of the WRs are running here in the UK.The bike starts and runs ok but is a little bit rough, what worried me is i got a glowing red hot front pipe fairly quickly in the garage!! and after doing the free mods it must be getting way more air so i dont want to ride it until i know more about the main jet. Many thanks .

I always hear very good things about the JD jet kit also, worth looking into that also.

In the bag ive got a black, screw thing with a HEX head this measures appox: 35mm in total length, non including the HEX fitment the screw measures approx:30-31mm. The thread part measures 6mm and is at the base of the screw.
A piece of hollow brass? total length: 28mm, has a thick section, with a thread 3/4 of the way up and a thin section with small holes (grouped in 2's) punched through it. printed on it: A STAR SYMBOL AND 48
A long needle type thing, approx 104-105mm in length, with 7 small grooves at the top.
A black hollow piece of steal. 46mm total length, and 13-14mm internal diameter. This piece also has a wrap of steal wedled in the middle and small holes punched through equally either side.

Ive got a 2005 model 450 and Make sure you remove the emmisions crap, this will make the bike run miles better. I run a 170 main jet and my front pipe still glows, I reckon it must be kinda normal on these bikes. Also open up the airbox on the right side and pull out the grey wire hidden under the tank,I did all my mods at once which took about 3 hours including the jetting.
Once I had done the emmissions the bike stopped popping on decel and is now pretty quiet compared to my old DUKE 2 with twin G Force cans
Oh and get some SM wheels coz there will be no offroading soon

Going to change to 4th grove see if this helps.Apart from that the bike is awesome 1st 2nd 3rd wheelies on power easy, smooth everywhere else idle ,pick up and flat out. Done all mods including the AIS emmisions cr*p.

Half way through my 1000km service, only the valves and the rear swingarm and rear shock linkage to remove and grease and Im done.
SO far so good however I wasnt prepared for the metre long horizontal oil flow outta the frame bolt when i drained the oil After a moment of panic I got it sorted though.
The problem with the 450 I have found is the more you cane it the better it gets, It just keeps getting faster until I loose my bottle and shut off.
I bet its a hoot with supermoto wheels on round the backroads

just take the seat and the tank off ( 10 mins ) then locate the wire block and pull out the grey wire from the correct side and tape it up, dead easy took me 20 minutes tops to do. There are loads of pics on here of what to remove, i cant post them though coz im only on dial up.
I found everything i needed on here in 30 minutes surfing, so for you broadbanders it should be simple.
any probs and ill help where i can

I'm going to do all the free mods and follow the guide on jetting. I have also read that changing the Leak Jet from the standard 50 to a 40 improves throttle response, making it crisper. Is this necessary?
I note that the grey wire is only found on 05+ models, so can I take it that my 04 bike is already running the YZ mapping? If this is the case I take it it will be ok to continue with all the mods and jetting?
As for the needle I will set this as recommended to the 4th grove, however any advice on fuel settings would be appreciated. I have printed off the info. that I found on this site, although the settings are from guys riding in much warmer climates. Any info. here would also be Gratefully received.
And finally, does removing the AIS emissions system make a big difference and where would you get a kit from or is it a case of filling the holes that are left after removal with rubber bungs?
Any advice on the above would be much appreciated.
