    I did a plug chop test the other day and it looked pretty good tannish brown. Gap was between .60-.65.. I looked in the reference guide and it showed this is 1 step hotter than stock. What does that mean? Should I go back to stock? Thanks

    I bought the bike with the plug boot broken off the coil wire.. I shoved it back on the boot with no problems but I'm wondering if this would cause any future issues....

    Thanks for any help, really enjoying this bike

    A BR9 is one step cooler but the 9 will foul easier unless you ride it really hard and have it jetted perfectly. I run a BR8 in my WR250 and usually change it once a year because it gets lead fouled from running leaded VP110 race fuel.

    If your color is good like you say and you aren't experiencing detonation (pinging/knocking) then the BR8 is the correct heat range for what you are doing.

    That is good to know. I was going by this

    Typical Plug for Husky 2-Stroke Bikes:
    BR9EG = fine electrode (Stock)
    BR9ES = regular electrode
    BR9EIX = iridium electrode
    Gap = 0.60 mm = 0.0236"

    Alternative Plug:
    BR8ES = 1 step hotter, with regular electrode
    BR8EG = 1 step hotter, with fine electrode
    BR8EIX = 1 step hotter, with iridium electrode
