2008年12月31日 · 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 ...

2020年5月13日 · 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...

2017年12月29日 · 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.

2008年3月29日 · +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.

2007年4月18日 · From top of my head the most notable changes - someone please correct me if I mess something up.... 1993-1995 same

2008年7月26日 · Also, keep in mind that these indicator-advance specs are unique to the '99-'09 YZ250 because of it's. flywheel-stator relationship, stroke, rod length and CDI advance programming. The results:-The whole area behind the flywheel is the moveable stator

2010年9月26日 · On my 2007 yz250 i run stock gearing which is 14 front and 50 rear. Maybe try a 14 front and a 48 rear for some more top end but you still will have a lot of bottom end. I run a renthal oring chai with a front sunstart sprocket and a aluminium 50 tooth renthal rear sprocket. Both are awesome.!!

2012年10月21日 · My bike was built for pro SX rider Ryan Clark, so it already had all the work done to it. I've simply rebuilt is as-is over the 5 years that I've had it. I feel like it has a lot more bottom/mid than any other YZ250 I've ridden, with about equal top end. But I can't say it's all the long rod, as the it's had a great deal of port work done, it ...

2018年1月2日 · 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.
