Your compression is probably OK, since it is correct with the auto decompressor "activated", i.e. normal operation. 86 psi at kickstart speeds sounds about right. With the manual release activated, 0 psi sounds about right.I compression tested my L after a new piston, rings and liner - after running for .I had my bike apart and decided to run a compression test.

As best I can tell, road racers want soft fast compression ("plush" over small bumps, potholes) and hard slow compression (resistant to brake dive). I don't have a good .
Honda XR650R is 87 PSI with decompressor applied and 160 PSI with decompressor not applied. It jumps all over the place so check your shop manual before you rip the top end off thinking the compression is too low. The screw on the reservoir is compression. If you look closely you will see a screw on the shock fork (bottom of shock that connects to linkage), this is the rebound.
There's 2 compression releases. One is actuated by the lever and is used for rotating past past TDC. The second, built into the cam assy, has a centrifugal force .

You were asking about compression testers. You would have over the top high readings especially if you coated the cylinder, piston and rings with thick assembly lube.

I ran a compression test yesterday and got 130 psi cold. Compression settings for the stock xr650l is 92 psi.
compression to be 200 +/- 14 psi. Low compression caused by: improper valve adjustment. valve leakage. leaking cyclinder head gasket. worn piston rin or cylinder. oil down the pipe is, i believe, the conventional way to determine if its a worn ring or cylinder (Versus valves/head). Good luck Anyone know what a good compression test reading would be for a 2001 650. Due dilegence on a used bike with well maintained bike with a few hours on it. I found a site that said a minimum of 100psi. How does the compression ratio 10:1 vs 11:1 translate into fresh psi? Any insight appreciated. You will now depend on the XR650R's manual compression release to find TDC on the compression stroke and take the piston slightly over the top before pushing downward on the kickstart pedal to start the engine. Once you can "feel" the piston's position, you can kick through firmly without risk of pedal kick-back injuries.
interesting my book says 185 - 213psi for a compression test. and stock compression ratio is 10.2:1 . with compression ratio it refers to the space in the cylinder and combustion chamber. with the piston at BDC the air space is 10.2 units and with the piston at TDC that 10.2 units of air is compressed into 1 unit = 10.2:1 A cranking compression test is very difficult with the OE decompressor mechanism. A leakdown test is performed at TDC on the compression stroke with all four valves fully seated, which may require loosening the valve adjusters. The leakdown test is more conclusive anyway.

They were fitted with knobby off-road tires and were not always street legal.The L version models were dual . A compression test on a single cylinder 4 stroke motorcycle is worse than useless. Most engines in this class use a compression release, and are supposed to have low compression at cranking speeds. Even worse, gages vary and testing methods vary, so without other cylinders to compare (the only value of the test) the test is more than worthless. There's 2 compression releases. One is actuated by the lever and is used for rotating past past TDC. The second, built into the cam assy, has a centrifugal force mechanism that reduces compression at kicking speeds. When the motor fires up, centrifugal force causes the system to disengage (full compression).
Compression 11 clicks from full in Rebound 9 clicks from full in Looks like compression is on the bottom of each fork leg and rebound is a little screw on the top (not the air-bleed) of each leg in the center. Now, for the rear shock: They list compression 6-10 clicks from full in. Rebound 11-15 clicks from full in. Now for the questions. The fork on the L is a 44mm Showa cartridge conventional fork that is essentially the same thing that many top off-road riders used back then.

The compression test you mentioned 10 to 20 psi is really bad. With a good condition engine pull the plug and simply connect the test device / gauge it should show around 92 psi that is with the de comp working. With out the de comp it should be 199 psi. You can disengage the de comp by backing off the valve adjuster. But 20 psi.. So I have a 2007 XR650R supermoto, its been an awsome bike for every one of the 8100 miles ive put on it. . i thought this would be the perfect time to bump up the compression ratio:bike: . And for God's sake put some high test in there. Detonation is like taking a sledgehammer to the piston. Hell I mix 100 into mine to get the octane up to . Hello everyone, my 2017 XR650L with 11k miles is blowing blue smoke at cold startup, it also blows black smoke when revved, after it warms up the smoking stops, is it possible that it needs new valve seals?.
