Realistically....probably low-mid 30's.

 

Yeah...Thats what alba said. With the kit a good pipe and an air filter it would be around 32-34 HP. Now that could be true about it being at the crtank...I did not ask...but it doeas have some mean power. The people that have rode it were shocked with the power it had.

 

I never said anything about the pipe giving me 30...If thats what you were meaning. The pipe air filter, and 400 cc kit is what gives me 30

 

A 400ex has 28-30 horsepower. You should be able to run with one...any buds have a stock one?

 

haha he should be able to smoke one man... he prolly has 35-37hp

 

My old motor has the same parts and mods as his except minus 45ccs and I had a lectron carb with the filter right on the body. Maybe mine was jetting like crap or something but it never felt like more than about 25 or so hp to me. Might of been more hiding in there but it ate another oilpump and scratched the cam so I packed it up in a box. Others with the setup have said theirs ran about even with a 400ex but my friends 400ex had a pipe and big bore so he left me like I had flat tires. I imagine the extra 45ccs should get you ahead of a stock 400ex and right on the tail of a piped one.

 

Yeah...Hopefully I'll run into some 400 ex's soon. I'd like to race one. I am very pleased with how well mine is running and it has been running very good for awhile now. No major problems.
