FE/FC Looking for some FE501 Feedback

Just spoke to them and they are not available. They asked many people and all said this was not the case.
I am providing some info they requested on mine to see what they can do.

Ill update as I get info.

I have the ecu programmer for the 350 and 501's but I have not tried it on an S model yet.

so do we (Andy FE350S) still need to keep our vegas appointment...or should we stop in to oak hills before heading the rest of way up the 15 for a trial run at S ECU map burn....?

Wish me luck. I'm hoping to be a 501 owner early next week. Previous owner really took care of it and has it all dialed in. Thankfully I weight as much as him, I'll just have to play with the sag at most.

Here's what the bike has

How many hours are on this bike? That seems like a really good deal considering he spent about $12,000 to build the bike.

I just picked up a new 15 FE501. NOT the S model. I'm confused about this euro remap. Does the non S model need a reflash or not?

AND if it does, what's the advantage? Also doesn't it have 3 modes to switch to?

Has anybody confirmed a Non S ECU can be used on a 501S model?

In addition, that the Euro map for a 501 supports the different ignition mapping options for 2 or 3 position handlebar switches?

I'm considering a 501S but want to nail down the ECU/map options first. I'd really rather be able to do a remap than use a PC5. I have a PC5+AT on my Husky TR650 so I'm quite familiar with them.

In general I really like FI, but with all the hassles of getting them reflashed these days carbs "almost" start to sound better. At least there were no restrictions with changing the jetting.

Thanks for those posting the info on the Acerbis 4.1 gal tank, that's perfect.

Any comments on good options for a 501S Tinken?

It doesn't NEED a reflash but it will run smoother and cooler with the EU map. If you opt for a switch you can choose from 3 maps. I did this and like it but it wasn't required. It will run pretty good stock. I'm referring to the non S model here.

I can map a non-S model from mild-to-omfg. Haven't tried the S model yet.

I agree, the wild mode on my 501 is wild indeed. It revvs to the limiter much quicker than the base mode. The mild map is nice for tight woods riding as well.

I think a LOT of us want info in the 501S model not the non S. Myself included.

So is this 100 miles per tank approx? Gonna try a 100 mile desert race for the first time this spring. Two 50 mile laps. If I can make one lap then I am golden. Thanks

Getting 100 consistently with 13/49 gearing. If I ride really tight single track I can do 75 miles. Forks turned crappy too. I pick my reworked suspension up Monday.

Forks turned crappy??? Why? Did you breath them?

Tinken,
I'm seeing lots of hate for the PC155 oil filter on KTMtalk for these 510cc motors. People talking about issues with cavitation and bypass valves.
I actually bought a PC155, but am nervous to install it.

Since I trust your opinion would you mind explaining what these folks are talking about and if it truly is an issue. I believe it was an issue on the older style motors, but I cant find any comforting words on the XC4 (or whatever they're called) single cam motors. Thanks!

We run them in our race bikes. Cavitation has nothing to do with the stainless steel filter. There is a bypass valve, but it will probably never use it due to the extreme flow.
