25 posts in this topic

I'm waiting till the end of October to pick up my '16.

Will buy the Power Tuner and I'll try this map

I'll use Akrapovic full exhaust system though.

I'm not to knowledgeable about the timing, can someone give me some input on what advantages are there on advancing it? Pros/Cons? Thanks!

I have always been nervous to mess with the timing map.. What are the odds or how easy is it to mess your engine up? i have only used the maps for my '14 in the picture i posted.. That first map has so much power.

I will try the map for you at least the timing curves.

As for the fuel its going to depend upon mods and elevation. I noticed the 16 ha a great bottom into mid range. Very smooth and a consistent pull. Although the top seems to fall a bit short.

I'm installing a good flowing intake to go with the yosh rs4 full system. I doubt that the bike is corked up factory but seems to feel that way on top. I'm sure it's due to the cam profile change , that I might add is great for tight stuff.

Don't take my opinion for anything tho , I come from a background of modifying these 450s. Even if there's no reason to.

That first map seems pretty powerful lol.

Do you have any feedback about it?

Just that.. POWERFUL! i maybe did one or two laps with that map and changed it. It was constant power everywhere definitely not for me. My bike has the gytr head cams and piston and  dr.d pipe. i damaged my engine last year and the complete GYTR head is a pretty good deal considering what u get with it. definitely added alot to the motor, but it is tame once i got the right map

The base map on all of them is zeros, but that doesn't mean that they are the same year to year; they aren't.  The '14 and '15 are two identical engines apart from the CDI, but you wouldn't know it to ride them both.  All of the difference is in the base map, and all of them are all zeros.

Thank you.

Anyone tested this map or something similar yet?

Stock muffler seems pretty quiet/blocked also, maybe there is room improvement also.

Btw, after I installed a aftermarket exhaust , bike was popping in deceleration, so I used this map and the decel-pop was gone. ImageUploadedByThumper Talk1445610699.630979.jpg
