Moderator Airhead Posted January 4, 2011 Moderator Posted January 4, 2011 what do you mean a jetting 'kit' ?
bobalicious Posted January 5, 2011 Author Posted January 5, 2011 sorry may have been the wrong phrase, i want to move up a jet size. i dont want to drill my own out, my bad haha
Moderator Airhead Posted January 5, 2011 Moderator Posted January 5, 2011 sorry may have been the wrong phrase, i want to move up a jet size. i dont want to drill my own out, my bad haha Jets are easy come by, I use motocarb they will post it to you. What size is it now?
bobalicious Posted January 5, 2011 Author Posted January 5, 2011 standard, 210 i assume? to be honest i dont understand how jet sizes are measured. iv taken de cat out of the exhaust so i reckon jets would be a good next move.. ye no doubt id get them in the bike shop here, but id fairly pay for them 2, i just wanna get a few prices on the internet before i hand over mad money yeno urself..
Moderator Airhead Posted January 5, 2011 Moderator Posted January 5, 2011 they are fairly cheap I wouldnt worry too much about the cost
bob-c Posted January 7, 2011 Posted January 7, 2011 First thing is to check if you are jetted ok now, the colour of the plug gives a rough idea, ideal is mid brown http://www.dansmc.com/sparkplugs1.htm If you want to be more specific e.g. if you think it is out at full throttle , then a plug chop will tell you , but it costs you a couple of new plugs No point re-jetting just for the sake of it , http://www.kawasakimotorcycle.org/forum/kawasaki-motocross-offroad/17227-spankeys-jetting-guide-info-2-stroke-riders-must-have.html http://www.thumpertalk.com/forum/showthread.php?t=538197 Bob
bobalicious Posted January 7, 2011 Author Posted January 7, 2011 its hard t tell the bike goes tru plugs like a mad yoke, dis last ones held up pretty well tho so il check it out 2moro.. iv the exhaust gutted, i flowed the inlet ports and iv a knn style filter to go on aswell, surely a bigger main would be a gd step now no??
bobalicious Posted January 7, 2011 Author Posted January 7, 2011 that kawasaki forum is class btw cheers dude
Moderator Airhead Posted January 7, 2011 Moderator Posted January 7, 2011 I wouldnt recommend a pod syle filter if thats what you are considering. More trouble than they're worth getting it set up right.

More trouble than they're worth getting it set up right. +1 DTR's do not like K&N's. A pipercross or similar original foam style one works better IME. And what do you mean by "flowed the inlet" ?
bobalicious Posted January 7, 2011 Author Posted January 7, 2011 idn men its all trial n error for me just took the dirty blunt edges off n smoothened dem down as best i could

Dead Right It is very tempting to mess with porting and exhausts , unless you are a skilled tuner you are more likely to lose power. Your efforts are best kept to keeping the bike in good order. Once you have done the standard de-restricting of a dt125 ,the next step is probably a pukka exhaust system like a DEP . After that I reckon there is no substitute for a bigger bike !
bobalicious Posted January 8, 2011 Author Posted January 8, 2011 no iv taken the blunt face off the inlet n smoothened it into a point, its still as bumpy as it was. its definetly better im 18 now in a week or 2, time for de bigger bike... in 2 years. thanks to the restrictions in ireland.
