How to tell if the PCV is working?

Or the Akro slip-on vs stock too.

I took the time to call a local dyno shop (only one for miles) & was going to get some AFR & power numbers but the bastard is min charge $160 first hour or part there of.
That's nearly a pair of tyres on a bike I know is running well, so didn't go ahead just to have numbers to quote....

I went from stock to PCV with the FMF Powercore 4 and noticed a major difference. Seems like the bike loves to rev now and has a lot more bark acoss the powerband. I was also able to tune out the starting and flame-out issues that I was having.

Is the airbox mod worth it? Just questioning whether or not I want more dust, etc. in the airbox.

Thinking I might bolt my never fitted cat exhaust on just to see how bad the bikes you guys get are.

The slip on Akro is very restricted as well. I still have one sitting in a box, the thing is a heavy beast.

Do you have a dyno sheet for a bike with one installed? I'd love to know how much is unleashed over the standard cat exhaust.

Okay so I now have a Barrett muffler on my bike instead of the factory pipe.

Amazing difference. Acts like a totally different machine. I never would have thought that an exhaust pipe could make that much of a difference. Honestly not getting a better muffler for the 449/511 is a waste of money IMO. It acts like someone put a 450cc motocross engine in it when I wasnt looking. The PCV is deffinately working. The top end is there finally. I have to actually hang on now

Which map do you have installed?

I uploaded the "Husqvarna 449/511 ZipTy Full Factory Race Map" that you have posted in the Zip-Ty Racing forum.

Try this one. Add accel settings in foot notes.

Will do when I am on days off. Is this going to be some crazy Nick Burson Flaming Balls style map?

Nah.. Nick's map is pretty tame compared to this one.

Is standard 92 PON pump gas sufficient or is race gas necessary?

92 is good

Totally off topic now, but could Zip-Ty Racing offer 449/511 crate engines? Kind of like how Speedbrain sells 449 engines.They could come built with almost all parts. Simple things like the valve cover could be swapped by the end user as a cost cutting measure (plus they are already drilled for the breather- some better than others). The original engine could be sent back to Zip-Ty for a rebate/core charge.

That's an excellent idea, but we don't have the engine cores to offer such a program.

Would it be possible to source the parts from Kymco? Where does Speedbrain get the engines from?
