Power output ???

[fandango]

OK guys

hawk 700 with
fcr 39's
flowed/ported heads
megacycle cams
balanced knife edge crank
520 chain

what sort of hp at the rear wheel do you rekon???

i'm looking at around 70-74 bhp at wheel do you think i'm way out??

kyle

[Doc]

Yep.

[fandango]

Yep.

hmmmmmm i best get to work on the case's / ign / flywheel then

[Doc]

I am just thinking that those numbers are a little high for RWHP.

Hord would know best.

add some 28mm valves and you'd probably be close....but then you have to think about reliability.

[Dash]

My thoughts exactly. it might spit its guts out if you wring it too much.

what the hell! that picture combined with the name just says bad things about whiskey. it should probably be removed

Hey if someone wants to post pics of himslef in his new Halloween costume who am I to stop them.

[whiskeypigeon]

Halloween costume? sheeeiiit, i wear this every night

seriously tho, if people think its NSFW then i'll change it.

[jregezeino]

hah. its all good

Your goal of 74RWHP is completely reasonable and should be reliable.

I would suggest that you save your money on knife-edging the crank. Also determine a realistic RPM for the crank balancing and not somewhere up near redline. JD can do a set of heads for you that will yeild good port velocity and get a good radiused valve job while your at it. I have used the stock valve springs with even the steepest of Megacycle cams and have always had good results. Don't forget to have your cams slotted so that you can optimize your cam timing (or as optimal as you can get with a SOHC motor). Also if it's a race bike and you want to pull the charging system that is your choice but leave the starter installed, you won't suffer any power lose and will always be able to start the bike.

With a careful build/setup you will have a nice broad tractable motor with a torque curve like a tombstone. Remember peak HP is great for drag racing and dyno bragging but your goal should be total area under the curve on your dyno sheet since that's what makes a good race (or street for that matter) motor.

Don't listen to these guys (they are just sour grapes) it will make mid 70's and it won't blowup.

What the hell do you know. Just look @ your avatar! Your stunting without proper safety gear! Some example you are to the children. At least Whiskey is wearing a helmet.

And what about your avater huh? 3 man on a bike. and all doing a knee down. you call that responsible? what if some kid decides to cross the track? or a bus of nuns suddenly pops up on the other lane? huh? huh?

btw: won`t it cost a freakin` fortune to tune the thing to such an extent?

If I had stopped with those simple and inexpensive modifications I would consider my hawk to be a bargain!
