Hi guys, so been up on the road on my recently done slabside 1100 fighter , the bike was put together from bits and pieces so the plan was to get some miles on it and test what's working and what's not , every thing seemed to be going okay apart from a few tweaks here and there , really wanted to test the engine as I was planning on getting it bored out over the winter, it's an original 1052 engine with dyna200 ignition, stage3 jets and pod filters, I noticed there is smoke coming from the engine breather with that smell of burning oil when it gets hot and it seems to be hot all the time! It seems to be going through a lot of oil ( over a litter in 800 miles) but it doesn't seem to be burning it in the cylinders , the engine runs and sounds okay but not as fast as I thought it should be so I did a compression test on it and it wasn't great ( around 100psi across the board if the cheep Chinese compression tester was reading right before it fell to pieces!) Was planning on boring it out anyway so wasn't to worried about that but figured I'd do an oil pressure test just to be sure , when the engine is warming up it reeds at about the minimum 40ish psi but when it gets hot it drops to between 15 to 20psi , I thought this seemed a bit low so I dropped the sump out and checked the oil pressure regulator and relief valve and they seem fine, repeated the test with fresh oil and got the same results, would really appreciate any advice here as this level of spannering is pretty new to me! Are these oil pressure readings on the low side? Replace oil pump? Combined with the low compression test is this indicating a worn/ knackered Engine? As usual any and all advice really appreciated
