Today i went to my dealer and picked up sled after he did updates including oil pump.I have 2750 miles on F-7 no problems but my oil ratio was roughly 110 to 1 i have only used a little over 2 gals of oil in this time?Ihad them do a compresion test they said both cylinders were 140,but he said when he took the pipe off and looked at pistons it looked like the top rings where worn.and he also said the pistons had blow-by but it wasnt that bad he said his race f7 was worse.So i took sled home and took pipe off there is brown blow-by half way down piston on both and also scares on pistons half way down.My question is this normal wear,or could this be a oil problem.My dealer said he could probably could get me new rings on warranty next year.I have noticed a power lose since 1800 miles mostly on midrange. sled has been gone thru top to bottom and nothing has changed,so should i just ride it till it blows or bug my dealer more about it? <_<
