is a br8es hotter or cooler than an eg? plus i have a br8egv whas that?

an 8 is hotter than a 9...and an 8 is colder than a 7....the lower the number the hotter the plug, and the higher the number the colder the plug.
I wouldn't run any lower than an 8.

you can try the clip in the top position temporarily, and I bet it'll run nice and clean....I generally don't like to max out like that...I prefer to find a needle where I can be right about the 2nd from the top.

it won't be that hard...Rocky Mountain has an N82P listed...

and these  guys have a good selection as well...it's best to call them and explain what your situation is, tell them what your current needle is(the stock N82M), and that you want one that's 4 or 5 steps leaner, and they'll be helpful in getting you a needle/needles that will work.

here is where we startedwith the bike almost a year ago[/img]and here is where we arehttp://i610.photobucket.com/albums/tt181/Coby_Hosford/bike/100_1649_zpsatdagcuh.jpg.a big thank you to kx riders forums.and an extra big thank you to Foxx4Beaver.after coming to my wits end after rebuilding my 500 basically from the bottom up on a low end rev slouch i found this site. i got a positive response from my inatial thoughts on what i had incorrect on my bike. i thought that i had reassembled the kips system incorrectly and didnt know how to do it right. after taking into consideration all of the comments, i decided to tear apart the top end again to try something one more time on the valve assembly. found there was nothing  to do differently than i had already. but then foxx4beavers carburetor tuning comments caught my attention. i went and leaned the pilot jet down a step and didnt really notice a big difference .so i went to the shop and got even a leaner pilot by 1 step. i then stared believing what i was being led into learning about at the same time. as foxx4beavers intial comments above stated the p[ilkot will be a 52-55 and io may need to go with a leaner jet needle. well today i tried out the beast with a 52 pilot with the needle as lean as could be clipped. and thank you for being patient with a carb newbie. she is running with no hiccups at all. so as foxx4beaver also stated above what he doesnt like to do as far as the clip goes on the jet needle. and what size i need and where to buy it. i love it here.my bikre loves me for loving it here too. thanks. thanks,thanks. now my 95 half of my present bike was purchased in coos bay oregon in 1998.brand new. only because the shop i went to didnt have a stator for the 1991 kx250 i was running around the florence dunes in vacation burnt up. the florence dunes was the first time i ever rode a 500. t never ever looked back.  so the front end is my 95 .if you look at the braking system, and the axle you will know. because a 93(which the rest of my bike is), other than the carburetor, mono shock, and rear brake assembly-from the 95) has a smaller axle shaft and i couldnt just swap rims over. i bought the 93 for $1400 last summer in boise. the other bottom end i built is a 1992 case with a new crankshaft and the 95's tranny and clutch. so theres my ride. its a kx 500 bastard child. am i allowed to say that? so0 my reaper is a resurrection from death. not a lot of cash but a lot of urgew to burn premix while going through tires and sprockets.  that shinko 505 hard terrain lasted about 3 months. any ideas where i can get a steel rear tire?

that's great news!...I knew we'd figure it out.
hopefully the N82P will be enough to get it running crisp/lean enough with the clip in the 2nd groove from the top...I'd really like to see you be able to find a N82T, but they're getting harder to come by. The "T" is what got mine running super clean/crisp with the clip in the 2nd from top.

that's good lookin bike!...I like that you've got the '95 shroud graphics on it.

thank you . and its amazing how just changing the seat  the plastics and shroud graphics can make a bike look like a totally different bike to the untrained eye. i e-mailed support for the jet needle you suggested to me. i shared my situation with them and now i wait. . ill let you know ..but for the moment the stock needle is hanging in there. how long have you been riding and working on these bikes? is there a bio you have i  can read to learn about your history and feel i can give you the respect you deserve by knowing  a little bit ,not asking you to re answer stuff youve already written?

I've been riding for almost 39 years....raced for 22 years...now I just ride for the fun of riding.
I didn't start working on my own stuff until I was about 19...my dad owned a mechanic garage/gas station growing up, so he did most of my maintenance.

As far as "bio's" for you to read....just use the sites "search" option...there's just about everything you'll ever need to know about the 500 right on this site, and a lot on the 250's as well.

cool cool. ya ive been on bikes since i was 8 when my dad got me an 1980 rm60. ill say one thing for that little bike. that little thing never ,EVER  gave me problem #1. out of all bikes ive had since,(im now 42) that little rm60 was the most mechanically sound machine ive ever ridden. i remember this spot that somebody had dug out with a backhoe or something and made like a half bowl about 10 ft high. by the time i outgtrew that little 2 stroke my friends and i were seeing how many of each other we could jump over from  the ramp we had groomed it into.  i dont dare jump the 500 like i did that little 60 34 years ago. i just dont have the desire to hit an airplane. ive pretty much worked in my bikes from about the time i was 18 orso when my dad thought i should be putting my money into other things . he was right ...but oh well. never have broken any bones on a bike. knocked myself out once ,got some nastry dirt rashes . even once when i had my 91 kx250 i failed to see a barbed wire fence gate wasnt open until the final seconds an d use the the full front brake,went over the bars and bounced under the bottom strand  to end up on the other side with my bike tangle in the fence. first thing i did was looked for cuts. i had oe of those little "HALF SQUARED" barbed wire cuts on the back of my flannel jacket. and that was all. no kidding. and once sprained both my ankles landing a jump,while i layed out in the desert waiting for my friend to show up and contact my parents. that one hurt. i got my boots cut off on  that one,spent a while on crutches. but anyway back to these jets. i looked at that site  from the link you shared and i managed to figure out one thing. even if i do manage to acurately cross number the jet needle i have right now.that wont be the one i want. so how can i know the # for the n82t without having one to go by?

I would just call them, tell them your situation and what you're looking for....they actually had me mail them a needle once so they could accurately measure it, then I had them send me 2 different needles...one 5 steps leaner, and one 6 steps leaner than the one I mailed them.

so...check this out. i just for whatever reason decided to check what needle was in the other carb i have is (i havent used this carb because for some reason the choke port has been sealed off with some sort of flexible putty?)and the jet needle in that one is an n82r. that  pretty close huh? i should try that on center and drop  if not pleased or should i just try second clip position off the bat.? that is leaner than a (M) yet richer than a(S)?

sweet...I myself would go right for the 2nd from top to start, just be cautious with winding it out too heavy....and if it runs clean and crisp, do a wide open plug chop, and see how the plug looks.
