Just spent an hour reading posts on changing the flywheel on the 426 / 450. Still confused. Just want to confirm - If I go with the GYT-R 9 oz flywheel for my 02 - 426 for better trail performance, it is a direct replacement and will fit under the stock cover. This is a welded unit, just pull off the old flywheel with a puller and install the new. Right??
