do a compression test and be sure everything is alright inside that engine bro... then worry about the jetting. i run that gearing also and my motor pulls it like nothing. i run out of gears way to quickly and am always shifting lol. might jump up to 15 front
i was shocked when i first seen the 14 beside the stock 13 just that one tooth made it look humongo.i was going to get the 15tooth but read u had to cut the sprocket side casing and i didnt want to do that.
ill try another compression test tomorrow im too grumpy to do anything to the blaster now
