    They need to modded to clear the oil injector ... Don't try to bend the injector ...

    I have used them but now use Pro X ...

    mod the oil squirter, as stated dont bend it, WSM should put instructions with the pistons on what has to be done, but they dont.

    See if you can find a good deal on stock cp's 8.4 pay a tad more and save time and aggravation our find a good used set and buy a brand new set of Oem rings if standard bore if not go .

    ive just fitted one in my 215 engine.

    as above the oil jet will foul. i bough the newest part number for oil jet and bolt and the newest type oil jet does clear the WSM piston.

    not expensive so worth buying

    Sorry I meant the rings
    as i had problems with dip stick popping out ,so I cable tied down and now I'm chewing up rings on about 6-8 hour rides - compression down to 75psi due to rings and I'm using BRP oil. Someone told me it could be the airbox as its coming from outside and not from hull I'm riding in salt water 98 % of the time.

    Yes. If your talking about the very latest wear ring. It's the best they've made.

    My friend if the dipstick is popping out your getting blowby through the rings or your bore is out of wack. Your crank case is filling up with air pressure. You are riding a ticking time bomb. Pull the motor bore gauge it most likely you will find yourself going .20 over . Stay away from that wsm junk for internals
