Whats the most powerful map for a 2012 wr 450f.

I have a 2012 wr 450f. it has a power tuner, ecu and a fmf q4 exhaust. whats the best most powerful map i can plug in? also is there any other good mods to maximize power for cheap money or do it your self type deal? i am looking to get the most power out of it and have it start up nicely too. would dyno tuning the bike be worth it? would the dyno help the bike as far as starting better and running better? please someone give me a solid answer. thank you

i got the tuner, ecu, and the exhaust. the bike starts like shit and feels like a 250f! should i dyno it? whats the most aggressive map for the tuner? and how can i make the bike start. is there any more mods i can do without building the motor to get good power.

No not really,if your really picky about a/f ratios then yeah,dyno it or just use powertuner from yamaha and use the sx/mx map.any different map apart from standard usually starts easier than the factory setting that i have found so far,when I bought mine it was a POS to start hot or cold straight off the showroom floor!when I set mine up on the Aussie map,did my pipe and other mods it fires up no probs!

Remove the vents (ducts) from the air box,pull the seat off and you'll see them,remove the throttle stop screw and use the shorter one they give you in your off road kit.

I have the maps installed on my powertuner so its set and ride,14/51 or 52 gearing I assume is on yours?

I have maps if you need them,I found mine online and they work very well.

Read the other post you posted,I've answered it :)

Go the the WR450F forum.

You need the complete GYTR kit if you want to get the full 48hp lurking inside the motor.

With just the ecu and pipe, you will get about 40 hp.

You MUST re-tune the new ecu to match the pipe and airbox mods per the recommended instructions.

Thank you very much for the feedback! yes i am very picky im prolly gonna have it dyno tuned. if you could post your favorite maps that would be greatly appreciated. mine was a pos off the showroom floor too my dealer is wack too because they told me i didnt need the tuner. they should give you the power tuner and ecu for free when you buy it. i have been reading a bunch of forums here about the bike and everyones had the same problem. either way thanks for the feed back.


Dunno if this link will work but that's where I found it for mine.there will be 5 maps there

      Hi Guys,
      So I recently bought a 1997 XR400. I've done some research into getting more power through some basic mods and rejetting the carbs. Though all of the ones I've found have been for post 98 XR400s so the stock carb set up is a lot different. Usually people are opening up the airbox, exhaust ect. ect. and Jetting their carbs up to 160/162 for mains around 60 ish (I think) for the pilot. However for the 97 model this is close to stock for the jets.
      So essentially what Im asking (Just to cut to the chase ) Has anyone got a 96/97 (maybe 98, not sure) XR400 and has done these similar mods, and what sort of jetting have to done as a result.
      Thanks in advanced, also its my first post so apologies if I havent done everything correctly.

      38MM Cast SmartCarb. Purchased a couple years ago for a yz250. Don't have the bike anymore, and it has been sitting around for about a year. Used, but in fine working condition. You can also purchase a different needle for different bikes, as well as rebuild kits from their website.
      Asking $250 shipped to continental United States. I can arrange other shipping options at the buyers expense.

      Hey guys I just bought a bike last night. So the seller said the bike will turn on but then die. We didn't try it because it was really late at night and it was raining (seat was wet). But he said if you bump start it, it will turn on and ride. So what do you think the problem is? I just want to make sure it runs... I probably won't be able to bump start it till Saturday (rain)... It's a four stroke, and I know absolutely nothing about them. Thanks.

      I know this topic has been discussed in the past, but I have not found any options available for the new 2018 bikes. I live and work for a new Beta Dealer (Auburn Extreme Powersports) in California, and we are having a difficult time mapping the RR-S bikes for full FMF exhausts. We have tried contacting Beta Support several times for this issue to no avail, and we typically are given the runaround when transferring to techs and secretaries. From what we can gather, the FMF flash is designed for the RR bikes, but not the street-legal counterparts. Every time we try to install the FMF map onto an RR-S errors occur, and the programmer screen goes virtually blank. We have heard through the grapevine that some are using the RR maps on the RR-S with success, but we have yet to try it, even on our own bikes for fear that it will permanently erase or damage the CDI. Any and all help or suggestions regarding this topic would surely be appreciated! Thanks, Ben.
