You have to put compressed air into the cyl to hold the valves up (tool goes in place of spark plug)remove rocker cover ,remove cam, belt or chain !Put engine on TDC and mark valve timing dot,s on cam wheels so it goes back together the same , replace the seals one cyl. at a time,white out makes a good marker fo cam marks.

I have a 93 honda xr200r no compression can I remove top end without messing up timing to put new ring kit


no compression can be from valves burnt or held open are you sure that it is the rings
if it is not an overhead cam shaft but uses push rods to move the valves then no problem
if it is an over head cam then no so get a manual on how to set the valve timing before you pull it down
you will need the book for all the torque settings and clearances any way including the ring gap for the new rings

One other thing you should check judging it being a 1993. Check the fuel pump pressure for adequate fuel supply to all those new components. If you don't get the correct pressure you will experience back firing and inconsistency in your engine performance.

On driverside of engine, oil leaking out around where I call the back cam ( one closet to firewall) at end. I am talking about opposite end from timing belt on engine. If I removed cap ( w/two star screws...


That seal typically comes with a pack that includes all the cam bearing seals and the valve covers seals. It very easy to replace. Remove the valve cover and discard the old seal, remove the old cam shaft bearing cap seals. Replace the bearing cap seals and the valve cover seal and replace the cap and cover. Tighten the bolts to about 30 lbs and that should resolve the problem.

How to set Honda CBR 150 timing


Make sure the motor is on TDC compession stroke when you take it apart.
I'm skipping the tear down because if you want to adjust your timing, im assuming that you already
have it apart.

On TDC place the cam in the head so that both valves are closed.
There should be marks on the cam gear.(cam gear is attached to the cam)
Those marks should be parellel with the head.
While holding the cam in its slot in the head, carefully put the timing chain over the cam gear. You make have to pick the back of the cam up so the front leans forward enough to allow the timing chain to go on.
Once timing chain is on, double check that the motor is still at TDC and that the cam gear marks are parellel; with the head. if not you may have to go one tooth either way to get parellel.
If Motor is still on TDC and your timing marks are good, then your done.

Put the valve rockers back on and the timing chain tensioner, adjust your valve clearance.

With then spark plug out, turn the motor over by hand and watch the valves open and close, if anything is in a bind or if feels tight then your 180 degrees out which means you had you cam in upside down. Turn the cam over 180 degrees and your good to go.

The rotor is keyed so the only way that could go out of time would be if the keyway is sheared, hence the rotor would move retarded or advanced hence back fire out exhaust or intake.

If rotor keyway is sheared, you'll need a puller to pull off the rotor and replace the keyway.
It only goes on one way. On The Keyway.

If your CDI isn't working it will have to be replaced.
If your signal generators isn't working it will have to be replaced.

Any chance the valve spring has collapsed? Cam shaft thrust washers missing? Cam shaft bearing gone bad?
