Was riding my 450, testing out a new speedometer, shifted into 2nd, moved a couple feet and heard a loud crack noise from engine area. Will not turn over, sounds like its jammed or seized from moving. My guess is tat the timing chain just exploded and fouled everything up. Haven't found time to open it up. Thought I'd go to forums to get some opinions on what to look at first. As far as back round info: Engine was opened up to replace some gaskets. replaced my valves and adjusted rockers to .05mm. Timing chain taken apart a couple times. Shifts through gears fine even though it doesn't run. I am not very fond of ktms or dirt bikes in general but fairly mechanically inclined. I don't know what to do so here I am on the forums. Any help or advice is much appreciated. Thank you.
hey guys ive had my drz for about a year and recently the little hole on the left side of the engine has started leaking what looks like oil, ive read it could be a head gasket or something failing but I have no other leaks and the bike still runs fine.
can someone please tell me what this hole is for and why its started leaking recently. thank you

So having a little issue with my 05 RMZ 450. Just recently did a top end fresh in up on my 450 and now it seems very sluggish and boggs in the low end.It does not have the snap it had before the build. The top end feels great lots of snap and power. So not sure if I have to get the carb tuned or it's something I'm overlooking on my first rebuild. Only got maybe 1 or 2hrs on the build. Any help would be appreciated thanks
