Works Connection Oil Filler Plug
James in WA
Nice cap
Its just a cap and it does that well. The stock plugs always look to me like theyre ready to fall out. Hand tighten only!

Tusk Clutch Kit With Heavy Duty Springs
Jody in MO
Tusk is Beast
Still going strong in a 2004 660! It's been 4 years of abuse on these and they still feel great! I can't believe the quality. Second to none. Tusk delivered as always!

EBC Clutch Kit
MARK in FL
Yamaha WR250R EBC Clutch Kit
Heavier duty construction and materials than OEM. The 15% higher compression springs is no joke, sound like a small number but even with a Magura aftermarket hydraulic clutch you can definitely feel it. Perhaps after a bit of wear in, they will soften a bit. Something to remember if you're running an old fashioned cable.
