(I assume this means the length and shape are the same as the 2002+ YZ250 knuckle, so it will mate up perfectly with the frame geometry, oversize tanks, etc.)

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5月23日 · Here's a quick reference jetting chart for '01-'08 YZ250's. It was made by taking Yamaha's manual recommendations and using the density altitude calculator to correct for altitude and temperature.-If you will be racing or running in open desert conditions, richen each jet by one size and the needle by 1/2 step

2007年4月18日 · A lot of people have said the stock pipe is different from 05 to 06.. Internally the engine is the same since 2003.

2016年9月14日 · I have a yz250 and i love the bike but it just smokes too much. I know two stroke is suppose to smoke a little bit but mines smokes too much. When i noticed it was too much smoke i found out i had a leak in the front exhaust pipe where it goes into the engine. Also another leak where the exhaust pipe and muffler separates at.

2014年12月23日 · I’m looking to replace my 1989 yz250 kick starter but I don’t know what is compatible with the bike.
