Want to pop your motor.....go for it.

Sayin.
FM...I didn't think he was talking about the marks on the cam sprockets. I think he's talking about the plates vs. the pins on the chain. See the difference in dan's pic vs. tweak's pic? No offense to tweak, but it's a bit hard at times to comprehend his description. Obviously the cam timing in both pics is identical and correct...as long, of course, as the TDC mark is lined up on the flywheel.

FM, I think most of us know the proper cam timing mark orientation.

good luck .
If you PM me your email I will email you the KLX 300 manual which is the base manual for the KLX250s. It has the info you need. You email has to handle about a 20mb file.

Golly neds, looks like those IN and EX marks in the sprockets are lined up parallel with the surface of the head. Everything is right, no pin counting needed. If it was off by one pin one sprocket's markings wouldn't line up now - would it. Whereas if the pin count is correct, but the IN and EX marks don't line up with the head when the T mark is aligned with the mark in the side cover hole, you've got serious problems... it'd be out of timing. The pin count means nothing, the T, IN, and EX marks lining up are the critical factors. If it is off by one tooth it will be quite obvious in the alignment of the IN and EX markings. In addition if the cam chain had severe wear it might also be apparent in the alignment of marks, but I'm not positive of that.

A pin count may be in the manual, but it's purely irrelevant other than maybe to measure cam chain wear.

Right, when he said "the only place the arrows line up on the engine are in the middle of the link not in between like it should." sounded , to me, that he was worried about the fact that the plates on the chain lined up differently than he had observed elsewhere. Plates do not matter, timing marks and pins matter.

Default well

i turned i crank over manually so far chain seems fine i and goes with compression. when the cam marks line up( on their sprocket) i check the crank and its still tdc. i coudsl make a video displaing it. i hope she fires up well. i just need to makre a quick run for luquid coolent and gasket sealer. still waiting on a top end bolt. thanks again ill keep u guys updated. i do notice when the compression increases it creats slack in the midde under the chain gurard cause of stress but i think thats cause its without the chain tensioner pushin in at all.

Hello, I am working on a 1985 ZL900. It jumped time and needed a new timing chain and it broke one of the rocker arms. It arrived at my house in boxes. Does this diagram work the same on a ZL900? Do you have any info on the cam shaft caps. They are all marked and have to line up with the valve cover holes and they have arrows. Thanks Torsten

Torsten, try here at the ZL-OA site. They're very knowledgable about the Eliminators. I'm a member there. They should be able to help you out.
