Dec 31, 2008 · If you ride a YZ stock, without applying any of the tuning advice you can find here, you will be pretty disappointed with the fuel mileage of the (100% bone stock,) YZ250. As noted above, getting the jetting just right, which takes some effort, & float height adjustment, are essential for good fuel economy. Setting your cyl. head sqush ...

Mar 29, 2008 · +1 on the Bel-Ray Gear Saver Oil for the YZ250's tranny. The other one that I've good luck with is Golden Spectro Gear Lube 80W(Transmission/Wet Clutch). These two seem to make my bike shift easier/smoother and the gear box also appears to be a bit quieter.

May 13, 2020 · Ok, I am aware of the differences between the 250 and the X, and know there are a bunch of posts about it, head, porting, transmission, porting, suspension, kickstand, CDI, power valve, pipe. Problem is saying the "porting and head is different" doesn't answer the questions I have. I am beginning...

Dec 29, 2017 · Ive always loved the versatility and fun factor a yz250 2 stroke has (track/woods/ whatever) and wanted more power- plain and simple- I own an Af500, a '15 yz450f and have had bikes for 20 years- I ride track intermediate and woods as fast as some of the better guys- a 450 in the woods was a tank- went right back to the yz after less than a season.

Apr 18, 2007 · A lot of people have said the stock pipe is different from 05 to 06.. Internally the engine is the same since 2003.

Aug 10, 2020 · I've owned the Gnarly and Fatty for my YZ250. For me, a slow Senior C offroad guy, I found the stock pipe with the FMF Turbine Core sparky was the best combination on tight technical trails. The Gnarly hit harder down low, and honestly way more that I needed or wanted. I was more comfortable with the OEM pipe. Sold the FMF's and found a back up ...

Jan 20, 2024 · are you doing hard enduro, with a rekluse?. i tried that combo again last weekend , and realized (again) it's a really bad idea to not have the ability to rest the bike against the engine braking, while repositioning it on a failed climb. i do have a lhrb setup, but getting leverage and shoulders in the right places means i can't hold the lhrb …

Jan 2, 2018 · I'd go with any yz250 for harescrambles. I'd recommend a 1999 or newer YZ250, because parts are easier to find. They're all good bikes though. I've raced a 1993 yz250, a 2001 yz250, and a 2008 yz250. In the woods, they were all great bikes. No major difference in performance until I started becoming a rather fast rider.

Apr 16, 2014 · 2012 Yamaha YZ250: If Yamaha would invest in new plastic and a better exhaust pipe, the YZ250 would be reborn. As it sits now, it is old looking and gives up easy horsepower to the KTM 250SX. 2007. The big change for 2007 was the swap to the N3EW needle that most hardcore racers had been using in 2006. The N3EW needle brought about a big ...

Oct 21, 2020 · Thank you for the info FLO_Rida. I like your name, I was born and raised in Orlando, Florida. I have already bought the Boyesen Rad Valve for my 2020 Yamaha YZ-250X, so I will jet it properly and hope their is some improvement, …
