Ok i have a 400ex that is bored to a 440 and i just rebuilt the engine about one and a half months ago. (new piston rings)
B4 i rebuilt the engine it would blow blue smoke at start up but once the piston warmed up and expands it wouldnt. Also it would gradually loose oil over time for some reason. Now it is doing the same exact thing and when i store it for one night or so and check the oil the next day its very low and no oil spots are under it. Now maybe its just burning oil when i ride it but im not sure bc its freshly rebuilt. I know the engine on my 440 gets REALLY hot when riding so maybe it just burns it because of that i really dont know. But no matter what it runs strong and never bogs or anything i mostly race 1 and 1/2 hour long harescrambles also. any suggestions r very appreciated
ps i have been running a 10w-30 and 10w-40 valvoline oil. But i just ordered some maxima atv 4-stroke oil thats 10w-40 maybe i should go thicker??
