Why would he want to run a hotter plug ?

Honda uses a cold plug from the factory the D8. Any mods you do it carbons up easy. Even with all things stock if you ride at WOT alot or race Honda says to go with a hotter plug. With the additions of mods including the dynojet kit which fattens up the fuel and he seems to.want to race alot, I recommend the next heat range thats all. Its not really a hotter plug just you go to the next heat range. If you want to stay with the D8, do a plug chop and go from there.

      Where you like to ride and what riding does for you?

      I like to ride in wooded and grassy areas. It takes my mind off the everyday routines and helps me deal with my father's cancer. Also gives me a reason to get involved with forums like this one.

      2000 Honda 400EX Backfires
      By Trent Finnessey
      I’ve got a 2000 400ex with a dg slip on muffler, it came with he stock muffler on it but the previous owner had the dg in a box so I put it on. I’ve been riding it for the past month and a half and every time I let off it backfires, and the other day the backfires got way louder, 2x louder! I’m concerned that I may hurt my motor? Why does is backfire??? Thanks

      '03 Honda Sporttrax 400EX Carb issue.
      By Dumass
      My name says it all. I have a '03 Honda Sporttrax 400EX with a new aftermarket carb on it that seems to be having issues. I can start it but it idles really rough and when I give it throttle it just kills the engine. I have tried adjusting the idle screw but to no avail. I am in the San Diego Ca area. 
      Any advice will be greatly appreciated. I would also like to get an owners manual for the thing too but can't seem to find a downloadable one.

      400ex with 450 carb??
      By Trent Finnessey
      So I’ve got a 2000 Honda 400ex absolutely love it!! I’ve had it for about a month, I ride with bruteforce 750’s, outlander 850’s and 1000 sxs’s and I was thinking of getting a trx450r carb and a full hmf exhaust. And probably doing the air box mod too, how much power would this give my 400? Just a little different or a big difference? Cuz if it’s not much of a different I’ll just stick with my dg slip on..... thanks!
