Question how much horse does the crf150f git modified?

RcWannabe

10 hp stock and slower than hell. With a 175 kit carb and air filter with a pipe you can get 14hp. But the bike weighs 225 pounds so no amount of power is going to make it fast.

Paxracing

is it a crf150r or a crf150f ?

More like 12-13hp at the wheel stock

With a 175 kit, stage 3 cam, 28mm carb, and exhaust, you can look at 15-18hp depending on your setup

If you wanna blow a ton of money, you can go even bigger and more powerful.. A little bit on the highside, but coeshow does make the 250kit which is capable of 28-32hp

But just depends on how much you wanna put in a 150f.. But with some people that dump $2,000 in there fiddy motors, I could easily see how someone could dump $2,000 into a 150f motor




btw 150f's suck for anything but trail riding or stunting IMO

It is a crf150f

Stuffing a CRF230 engine with a HC piston and cam in is likely cheaper than modding the standard lump. Should bolt right in.

Towlieee

I think they have different cases dont they?

Or at least a different top end/head right?

firepower354

Not so very different. I think that the newer e-start 150 is basically the same as the 230. I'm FOS often though...

Towlieee

What does FOS mean? haha

I'm not sure if they are different, but if they are the same, that would be sick..

I'd much rather get a E-start 230 and put it in my kick start 150f If I could, and upgrade it

jrotten

better off with the 150f with a 230 bigbore kit,with the kick start you can run a inner rotor ignition, you can't with the e-start

Towlieee

i'd never run a inner rotor, I gotta have my headlights

I found out from coeshow that 230 motors bolt right in..

Now I'm considering a 230 motor with a 250 big bore, 30mm carb, cam, and exhaust... mmmmm

Would be a good route to go, since I don't like kick starts, and kick starters are prone to going out on 150f's I hear..


edit: also not to mention the only bore kits for the kick start 150, are teh 170, 175, 190, and 250 kit..
The 250 kit is expensive $1200..
Whereas the 250kit for the 230 motor, is only $500 I think..

I figure I could probably get a 230 motor for anywhere from $300-$700, and sell my motor for $200-$400..
Then bore it to a 250, get a big carb, cam, and exhaust, and see where that puts me

I hear with the 250 kit, I should be looking at 24-26hp+, with TONS of torque all the way through the power band
