Already put a different map in the bike and went up a tooth on the rear sprocket. Any suggestions mapping etc. ? I ride MX only , always ride 250f and this bike has a ton of power and it's wearing me out

Try a smaller sprocket like a 48 tooth.

Can you add a heavier fly wheel?

MXA map and run a gear higher with a tiny bit of clutch work.  It'll fly.

Ghill28 is right. You cant ride a 450 like you do a 250. If you try manhandling the 450 your gonna have to be in really good shape and be prepared to hit the ground at epic speeds. Short shifts and a smattering of clutch as necessary.

What MXA map? So go back to the 49 tooth rear ?

Look up the review MXA did of the 2014. They included a recommended map. Lots of oomph.

Going up a tooth causes more low end hit. The 15 had smooth power and uses a 48. So a 48 rear sprocket and a smoother map.

Every 450 I ve owned since the 03 seem to like an extra tooth or two on the countershaft

I would also suggest you look into the Dr.D NS-4 slip on. I added one with the stock map and it smoothed the bottom nicely and felt like it pulled stronger through the mid. Dr. D also can supply you with a map for their pipe that you can try.

Pulled an RV.  :ride:

 

I agree with Wes.  I have the Dr D setup on mine, and it doesn't seem to hit on the bottom like my 2011 YZ450 did.  It does feel smoother, and pulls harder higher in the rpm range.

Got one to unload if anyone wants. Was keeping as a spare because I liked the low end hit of the stocker so I put a sparky on that instead. If I ever RV myself I can have a spare..

I'm too slow to take digger, more likely I tipped because I was moving too slow!

Heck no! I'm slow but I like my ride plush. They were done by Shock Therapy a week after I brought her home. Stock was good, re sprung and valved, priceless.
