Low compression caused my bike to not start, does this mean my top end is fried?
Honda Rob posted a topic in CRF250R & RX
Before I put my 05 CRF250R away for the winter it was running weird. I noticed it was leaking oil out of the engine cover. It was understandable because i had just put a new stator in. The bike had been running oddly for some time before i realized it was leaking. I just took the bike out for the spring and now it doesn't even start. I bought a new engine gasket to try to fix the leak. I am currently installing it. I am wondering if the low compression could've messed up the top end? I rode it with low compression for about three weeks before it started to bog so bag i couldn't ride it anymore. Will replacing the seal fix my issue or have i created a whole new one? -
All, Question regarding expected compression after rebuild. 2001 DRZ400e. The head was redone by fast heads and I installed a new piston and rings. The cylinder still showed honing marks and had no scratches or gouges, so I cleaned it up lightly with a scotch brite pad (at opposing angles) and hot soapy water and put it all back together. My only spark plug broke during re-assembly so it has not been run yet. The rings were installed dry per directions in the sticky - I did oil the skirt however. I turned it over a couple of times to check compression and I'm at 60 psi. Is that normal for a rebuild that hasn't been run yet? I'm hoping that is because the rings have not sealed up fully? Thanks

Does anybody know where in the US I can buy a ring set? Failing that a piston and ring set for a 2001 Gas Gas 321TXT? How about a part number for each as well? Thanks

My kx100 won't start. It gives a little purr when I kick it like it wants to. Spark plug is good. I never took apart the bottom end so idk if that could be bad. But I changed the piston but don't ask why but I used an old ring on the piston and one new one. The cylinder has a gash in it kind of like it was grinded by the piston a bit but that may be a problem. It's an 08. I tested the compression and got 85, and then tested 75 so it's bad. Could one bad piston be the problem? The piston was torn up bad so I'm sure the ring was bad. It was sharp too. Could that solve it? Thanks

I have a 2002 drz400s that just hit 11,500 miles. I've owned it about 1000 of those miles and they were done some highway, some urban street and some trail. I had an issue a while back with the float needle seat o-ring letting fuel into the oil, changed the o-ring and that seemed to be the end of it. At first the bike wasn't running great but after fixing that carb issue, a 3x3 mod and a JD jet kit I'm in love with this machine...which is why I'm very concerned about her drinking oil!!! Ive noticed over about the last 300 miles or so it has gone from full on the dip stick to about half. This morning I took her around the block to get her all warmed up and check the oil and it was about 3/4 of the way up the stick. This afternoon I did about 40 miles highway and 20 miles trail and came back and checked and it was half. I decided to dump a little oil in there until it read full on the stick. I"m confused because the bike is running pretty well and if it was drinking that much oil and had bad rings I would think this would be noticed. There are no leaks on the floor of my garage or any signs on the engine thats its leaking, also no sign of oil in the exhaust. So ...What could it be, is it immediately serious, and can I just keep adding oil and get another 1000 miles out of it before I have to rebuild her?

So I just bought a 2017 rmz 250 and I was wondering how often I have to rebuild the top end. I figured as long as a keep the oil changed every 3 hours and a new oil filter every other oil change and keeping the air filter clean I wouldn't have to touch the top end very often but the book says every 20 hours and I don't think I can fit that in my budget so often, any opinion is appreciated, thanks.
