Topic: Timing chain help

[Jmed22]

Wanted to upload a video of my problem but would not let me as tgere seems to be no option for it. I need some help with my timing I believe I have too much slack in my timing chain because I can rotate my crank back and forth quite a bit ( maybe 1/4 inch) before my cam turns which is causing me grief and getting it to time right I am not sure how I can adjust the timing chain with the tensioner or if that is too much play please any help would be greatly appreciated and I have been struggling to get the old girl back on the road

Was also doing some researching and had found that there may be a as many as three different style gasket for my engine? Only reason I am bringing this up is due to the fact I am going to need to pull off the side cover and obviously we'll need a new gasket set but am worried about ordering the correct one as this has recently come to my attention.. any help on this issue I am having would be great and would greatly appreciate

What bike is this for?

If not a SOHC4, it needs to be moved to the Other Bikes page.  You'll probably get more answers if you include the pertinents....
Year, model...etc.

Its a 67 Honda cl90 and its a sohc bike.

There is a cam chain tensioner on those little bikes. Do you have a shop manual? if so, check it out. I believe it comes up from the bottom.

How many miles. Popping the top on one of those motors and changing the chain is pretty easy and cheap. I've rebuilt so many of those could almost do it in my sleep.

No I do not have a shop manual on it I have been doing some research and was told that some models were non adjustable and some were. I am pulling the motor out right now so I can put it on my bench to make it a little easier to work on

Definitely believe there is too much slack in the timing chain as I can move my crank back and forth a good quarter of an inch before my cam starts to move which makes it near impossible to time it

 Yes, but it's not a SOHC FOUR.
 BTW, cool bike and I have a CL70 and CL90 in the line up. But this does belong in the OTHER forum.

Join the Yahoo group for the S90.  They have a scan of the gasket sets in the files sectionyou can id the correct gasket set from that scan.  It appears your CL is a late build with the ruby red metallic candy paint.  Mine has that color too.  Shoot me a few photos of the complete bike, interested in seeing them.

the tession use to be a small schrev vith a Lock bolt..unscrev the Lock bolt and Loose a bit..then a spring vil press the adjuster aut..and it vill adjust itself..then redo the schrev light inn,,and turn tye Lock bolt..to sekure it..its the vay to do the smaller engines..but the 90 is sleightly different..

think the engine use hydralik..oil pressure to teighten the thain too..so there vill be a lot of slack at no pressure..try to pressure ot up..and thek the thain..just push the bike and feel vith a finger..if it teighten up..
