Plugged my AI hose, and did a Hunterworks muffler tip. The less restrictive tip not only made a noticeable improvement in power, but the the whole rear deck runs cooler (the exhaust winds close under the rear deck). All it cost was was whatever the exhaust tip was. My '22 XTR has been running perfectly for ~1K miles, in various challenging terrains and altitudes.
I would have no idea how to prove what the mileage is because the terrain is always different. But we used to used a full tank on a full day ride and now we use only 3/4 of a tank. So it seems to get better mileage, but I have no idea how to quantify that.
@@carlosandrade7439 I think a stock Yamaha clutch runs 18gram weights. I’m running stock size tires. The 22 gram weights engage the clutch faster at lower rpm, that way your machine isn’t screaming in your ear. You do lose a little top end, that doesn’t bother me much I’m more of a exploratory rider than a racer. If you reach out to Weller and tell them what you have and what your looking to achieve they are great at helping. Hope this helps
After running it for several hundred miles, I would say it's still too F'ing loud. Not fully sure if it's any more quiet. It does run WAY cooler for all occupants of the vehicle, especially those in the back.
I can't say how much the ECU can make an adjustment for that and still get the air/fuel mix within range. You'd have to ask Weller. I would assume they can tell you from the dyne results that must have done before they developed the flash.
I ordered the stuff from them. They offer a kit with everything. Tuner, tip, weights. $675. Top end 78. Not noisy. Sounds great. Huge improvement from stock. Stock i hated this machine. $675 I kinda like it. Still slow as hell but oh well. At least it doesn’t sound like 90,000 pieces of metal vibrating now. To put into perspective how unbelievably slow this thing is I have the two seat LE. I also have a 2019 Polaris ranger XP 6 seater that is 100% stock other than an ECU flash from Gilomen. Top speed was 57 now it is 83 and it runs and sounds amazing and will absolutely just drive away from my rmax at any speed. So it’s 600lb heavier utility machine and makes this rmax look stupid.
I just did the same I was in Arizona on vacation. I took my computer they juiced it with the weller tune and I bought the tip and block off plate. I did the 22 gram weights in my first 200 miles I owned the ma nine. I have to agree sounds much better and runs a lot smoother.
