  • Tusk Clutch Cover Gasket

    Tusk Clutch Cover Gasket

    Kevin in CA

    not for rfs, apparently

    never understood how a gasket could be inherently "bad" but this guy would not seal on my 525. i was astonished at how much this leaked compared to the factory "ktm" gasket i purchased later, after reading reviews about how the Tusk for whatever reason wont seal a ktm. there is a huge difference in material between the two, with tusk being green fiber and ktm being something . . . .im not sure how to describe but it is i think a grey fiber with maybe a coat of silicone. i put an extra, thin layer of rtv on the ktm gasket and it leaves not a trace of oil. the tusk would drip before my eyes. im not an idiot and have been wrenching on things for a while so i cant chalk it up to "mis-tightened" bolts

  • Hot Cams Cam Chain

    Hot Cams Cam Chain

    JON in WA

    Poor build quality in comparison to OEM

    I recently purchased the Hot Cams cam chain and was blown away that this chain is supposed to meet or exceed OEM. It is frail-looking in comparison and the quality of metal looks inferior and the links seem very loose for a new chain. The 100+ hour stock chain I was replacing had far less play and appeared to be the "new" chain when compared side-by-side. I returned it and will stick with OEM.

  • Dirt Tricks KTM Timing Chain Tensioner

    Dirt Tricks KTM Timing Chain Tensioner

    Miguel in FL

    Incredible! No more awful noice at cold start

    The OEM timing chain tensioner is awful, since it is hydraulic, it takes some time to charge from a cold start and the engine sounds like it is going to break!! I installed the Dirt Tricks Tensioner in about 10min and the noice disappeared completely right away, now it has a better idle, it doesn´t stall on trails, it´s a night and day change, it´s a must have from the OEM!!
