XTREME KARTS XF 1,212 Posted November 13, 2014 Hey fella's A mate of mine has an XB with the 250 log motor and needs to adjust the rockers, whats the correct clearance to set them at? Also do need to bleed down the lifters or are they a solid type of cam instead of hydraulic? Its the original engine so no flashy "go fast bits" etc. I've never played around with the eariler sixes so i thought i better ask first. Share this post Link to post Share on other sites
bear351c 10,270 Posted November 13, 2014 I thought they all had hydraulic lifters. If she's rattling, the lifter is fooked, or the pushrod is bent. Share this post Link to post Share on other sites

Yeah true, well i adjusted them and they seem to be fine now apart from the bad exhaust leak, someone forgot to put the last bolt in for the exhaust manifold at somestage.

PRO250 1,506 Posted November 14, 2014 Its not a solid cam. Turn it down till you can no longer lift the rocker and half a turn after that 2 Outback Jack and XTREME KARTS XF reacted to this Share this post Link to post Share on other sites
