I've installed several of these kits,the newer yr model kits (19&up) are a completely different cylinder head,not just a CNC Ported oem head as in years past.Parts seem to last longer then most of the aftermarket stuff so that's a plus.Only thing I would like to see is a better quality timing chain as the 250f yammie seems to stretch em out fairly fast with the added PONIES,especially with a A or Pro rider aboard.

Dont know,what those guys here are are asking for with "no added low torque".The YZ250F is known for having plenty of torque for a 250,just needed a little more overrev.That is ecactly what gytr adresses with this kit.Well done in my opinion.

Yamaha250f has is almost dead last on the dyno in there stock settings yet everyone that rides them rates them top 1-2 in shootouts for 3 years straight. Dyno doesn’t always relate to how bike is on track. Prime example Honda 450 19-20 had great dyno numbers but it was to much power which meant it didn’t get the power to ground it had so much power it caused wheel spin and felt like it was pulling your arms off.

I’ve got the 23WR 250 F with the GYTR competition ECU I had to fabricate my own gytr race baffle , for some reason I couldn’t order one from Canada. Everything else on the bike is my exhaust and airbox are stock .it opened my bike up exactly the way I wanted and I noticed that with this competition ECU at around 6000 to 7000 RPM it’s like it opens up power ban or something and the bike open up. You can hear the change in the rev. So with this GYTR competition set up work for the WRs because they are a competition bike also right

Hi, i would like to hear a bit more details about the vortex ignition. It sounds like just benefits, but I got another experience. You should run 98 octane and above. If you struggle to get hands on the fuel , you need octaneboost. I did try to run it at normal pump gas 95 octane.(engine knocking)What can 3 octane do? It lasted 6 hours and cost me 5grand to fix the engine.(all new except new head) Im putting the vortex away now, and will run stock ecu. Just a heads up, for the lazy people like me.
@retroretro-x2q Жыл бұрын
Standard octane booster is not good to run in bikes for so many reasons I’d just get pump 93 and mix it with vp112 at 1:1 ratio or take it to a dyno and run a e85 blended fuel with standard pump gas

My 22' 250fx does the same but only noticeable at dusk/night. My bike is bone stock, haven't even changed maps. I think it's ok and runs great, no signs of detonation on the plug. Thought about fattening up the lower 25% map but really like the crisp throttle response.
@okcmoparguy724 Жыл бұрын
So to answer your question I think the light throttle maps are probably on the ragged edge of lean but if it were a problem I'd see signs of detonation. Pull your plug and check the ceramic under the electrode for signs (google it). I think under higher rpm and load the tune runs richer for a safety factor. All of these variables can be manipulated though through the tuner. Try one of Keefer's tunes, good reviews on thumpertalk.

Not near the same tho. The YZ450 is unbalanced, pitches under breaking, and the motor is very on/off feeling. The 250f is an incredible bike tho that doesn’t seem to have these issues. Plus it is way more fun that a 450. On a 450 you feel lazy, where the 250f allows you to ride much more aggressive. Plus much less flywheel, and a much more free feeling. Night and day difference. The 250f is a blast.

Its virtually impossible to retain all the low end pull the stock machines have and make gains everywhere else in the powerband. All the money in the world can't change the fact a modern 4 stoke internal combustion engines designed by Yamaha make gobs of low end grunt bone stock. Keep your bike stock if you value off idle transition more than having better power everywhere else in the curve. I personally hated how my bike felt stock.

@@NickW90 no one needs to “gain” bottom end power on a YZ250F. They easily could have if they wanted to but it already hits like any other brands 450 off the bottom, they increased the feel from mid to top in order to increase usability and window of available power. That’s where the YZ “lacked” in comparison to others so now it’s more well rounded, no one asked for more bottom from a Yamaha.

I’ve got both a yz250 and 250f. Two-stroke is a blast to ride but I am faster, safer, and smoother on my 250f. A top end for the two stroke is about $150. For the four stroke, $200. If $50 makes or brakes you over 50 hours you are not in the right sport. If you change your air filter regularly and oil it properly the valves are not going to move for well over 100 hours.
