Whats the best way ti increace the HP without breaking the bank?
Cam,piston????

Cheers.
 
I have a barrel and piston that will take your bike up to 550 that I'm selling, came from a running engine that I stripped for my 650?
 
In that case, you could change the cam, the ktm rfs cams are the same just cut the waterpump drive off. or the best mod I did to mine was fit a fcr 41 carb?
 
I have a carb from a KTM 525 / 02, is that a fcr?
will try remember to have a look tomorrow.
 
Have had a look at the ktm spares site and cant find a 613 cam, am I missing something?
If you have a part no I would be relly happy :bounce3:
For a cam + hc piston combo?

Keep the ideas comming.
 
hc piston: wossner
ktm 613 cam: ktm part number: SMS36010000

You have the stock exhaust on your bike?
 
Not a stock exhaust, thing is the motor is in a crosskart.
Have been thinking of rebuilding it for a while.
Guess it would be smart to start with new pipe + FCR carb?

Thanks for the input.
 
Yes I think it would be smart to start with a 41 fcr (if possible mod in 42.5 mm)
and an exhaust kind akrapovic, doma or FP
 
Be sure and have a look at the DOC.

Make sure the crank float is correct.

Make sure you have the timing set correctly, you will have to use a strobe.

Make sure that your jetting is spot on.

Have SPARKS rewind your stock SEM ignition so it will last, and provide spark that will be consistent, strong, and won't get snuffed out at high rpm's and WOT.

As far as exhaust goes, just get a slip on that will allow the motor to breathe, the stock one is trick looking and super quiet, but very restrictive. This one mod will really wake that bike up.
 
I do softer valve spring kits
also a jetting kit for the FCR that has had great reports!
I can re-programme the ignition for racing
look at oversize exhaust valves? 31mm or so with porting to match?
I also do a lightweight cam chain and alloy sprocket set.
I also do a belmouth and cone filter conversion for that FCR carb

Taffy
 
Dale, what's the DOC? sorry if I sound stupid, first 4stroke + Berg + all the folks around here speak Swedish :cheers:
Taffy, wish I had the budget, will try the carb next outing .
