Kaw FC540v HP Secrets
« on: March 19, 2015, 09:18:56 AM »
Anybody have any HP secrets they are will to share?  Has anyone tried a Mikini flatslide carb on this motor?  Different valve springs??? I am running stock cam and flywheel.  Anything else can be changed.  Thanks for any help you can offer...

Depends on what class you are attempting to run.
We run 10 of these 540's in GP-ModXR class with much success in bone stock condition as delivered from the factory.
The Carb is the weak point, very lean low speed jets.

No Billet Parts available commercially unless you machine them yourself.
The Mikuni Flat Slide will be Illegal in most classes.
The cam is actualy quite large in stock format.
The stock Valve springs are decent, they usually do not float until around 5.5k rpm.
DO NOT run this engine without a governor with the stock flywheel, the counter weight will come apart
very quickly.

We found much success with this Kawsaki FC540V engine, especially of you just leave it alone and run it stock.

Thanks Flipper.  Big Al, we are in the EUP of Michigan.  We have an open class and I can change anything on this motor except flywheel and crank/cam.

If I keep this motor stock, what are the best front and rear pulley sizes to run with a 5 speed rear end?
