The valves sound a little loud but other than that it sounds good.
My bike has 37k on it and the valve cover has never been off. My 01 sounds quieter than that but my exhaust is louder tho so that may be it.
3k miles on the front and 1500-2k miles on the rear.
My 01 is at 38 front 34 rear right now
I ran my 06 fz1 at 34/32 rode it a lot harder.
My zx14 is at 44/25 for dragracing and 38/34 on the steets 34/32 if im riding hard.
Dusted it off and rode 120 miles. Took the brakes apart and cleaned them up while I was at it I cleaned the chain and pulled the wheel bearings and regressed them rolls much better now. Pulled the carbs again for the 1000th time and tinkerd with them trying to get the fueling perfect.
The 01 just hit 40k and the motor has yet to be opened up. Maybe that's why it don't run right anymore. It is a spare bike so we don't do anything to it unless we have to. This bike has had nitrous ran though it several times and she just keeps on going.
Living in the dirt sucks.
1. Spark Plugs - supposed to be done at 8k miles but many posts have said you can go longer (which I went to 12). I will probably do NGK Iridium plugs any reason to not do these?
NGK cr9ir is what I ran in mine
2. Throttle Body Sync and throttle adjustment: Love...
Apples to oranges
The zx14r made 214hp with the stock filter and a full system your Fz1 will not make that kind of power without nitrous or a turbo.
Get a filter open up the airbox and a slip-on and a tune the bike will be at 145+hp at the wheel.
