I have an 09 xp, I just put a new set of mcb dual ring piston kit in, piston,rings,bearing, wrist pin clips and metal base gasget came with kit, I tried pulling over with plugs in it it will only pull over like two lobes not two revolutions on the third the compression builds I'm assuming si high it stops the engine from turning, This is the rest of senarios I tried . I'm using the word lobe as if the rotation is like a lobe on a cam , u know when u pull your sled over slowly u feel it stiffen up as compression builds then it let's go for a sec until the other cylinder starts building pressure , I'm calling that feeling a lobe. 2plugs in ..... Pulls over 2 lobes, will not let it roll the third1plug threaded in 4 threads...... Can get to pull over to the third actually with one plug screwed in all the way I started it for a sec but then I killed engine, I then did it with the other side but broke pull cord when it started No plugs pulls over with easeI removed exhaust system , raves, put plugs in and same as above will only pull over 2-3 lobesSo I believe I have eliminating piston fetching up, plugged exhaust etcCompression is 148 cold of course at 1500 feet , I also put a terra alps head on with 13.5 domes Has anyone seen this before , is it possible that the base gasket is too thin, would it actuall cause that much compression for it not to completely roll over with one pull of cord , pistons r definitely have arrow pointing at exhaust , rings writing up , I'm gonna go check the kit packaging to make sure they r for an 800r verses 800 ho or wat ever , plus redo pull cord , please any experience in this would be greatly appreciated, I'd hat to have to tear the cylinder off again I got way to much on the go , I'll be in garage awaiting any input.Thnks
