I think thats a little conservative. Id say 45whp with modded stock can and jetted right. Then add 41mm bore to the carb and hmf full system and youll probably see around 48-49whp and 36ftlbs. Itll run alot better. Dont you agree Walt?
We dyno one of our 450xc with CT pipe and different cam, got 47whp . Next month we will be putting the second 450xc with motor work, bored carb 43mm/dial a jet, cam, twin air filter/power flow cage/No Toil, CT pipe with 20 disk (stoke is 14 disk), case vent check valve, open air box and Baldwin oil cooler. Waiting for it to warm up alittle so it will be ready for the Extreme Dirt Track Series.
After second dyno, will post both results.
