Took the bike for the free dyno day, my F3 got 84.6 HP an the misses bike made 88.1 HP. I read post that the 1996 f3 made 100 HP at the rear. Which we are off 12 to 16 hp, this could be a number of things but most likely a carb cleaning needs to get done.

My might be the carbon builded up on the valves and most likely the pistons.

Seaform is being used until I am able to pull the carbs and header to do a scrapping.

 

My guess is the best you'll see on the F3's is somewhere around 90-96HP.

Replace rings, valves, clean/synch/jet carbs, hi flow filter, repack exhaust can and do a 520 conversion with aluminum sprocket (just for the dyno, they suck for actual street use).

Maybe even throw in a cam job and you'd be bouncing under 100HP. nice numbers though for some daily driver F3's! Good work!

+1 on the SeaFoam.

 

Whoever said 100hp at the rear wheel was either telling porkies or was using a very optimistic dyno. All the F3 dyno charts I have seen, where the bike is relatively stock maybe with an air filter and slipon, make around 88-89 HP at the rear wheel.

Could have been 100 at the crank. Thats the figures the manufacturers normally publish - especially back in the day.

F3's are supposed to be 100-105 at the crank, 85 or so at the wheel. The guy who sold me my bike said he changed the heads (and added a slip-on) and it dyno'd at 95 at the wheel. Since he gave me the stock heads I'm inclined to believe him.
