Ive heard the front runner hondas like Byrd have around 65whp. i dont doubt it. I run a dyno and ive had numerous 450s on it that produce 60whp
for instance
08 ltr
cp 13.75 piston
venom port
web stg2 cams
yosh shelf pipe
fuel intake
pim
Tuned by me it made 60whp 36ftlbs.
With just yosh, fuel intake and pim it made 50whp. So 10whp gain with all shelf parts. Tell me that national racers dont have motors with more hp than that. One off heads, one off exhaust systems, custom everything. This was still on stock valves too.
Another bike I did was a 07 honda
13.5 cp piston
43mm carb
local head port
06 hrc cam
ron woods pipe
fci intake
this bike did 59whp 35ftlbs. with all shelf parts. Stock valves and mild porting.
Another was a 07 yami
had 13.1 cp piston
+1 valves
web 2 cams
local head porting
fci intake
dasa pipe
43mm carb
cdi box of some sort
61whp 36fltbs. All shelf parts This bike rips. though nothing special here. All parts bought over phone.
Those factory national motors are doing big numbers with massive power curves. Dasa motors are putting out big numbers and if pro-tec is doing more the motors gotta be in the mid 60s.
55whp setups will get straight owned in the pro class. I can get that outa an ltr with just some bolt ons, piston and cam.
