Back on a YZ..... 2011 YZ 250

Recommended Posts

I have had 3 Yamaha's in the past and always loved them. All of them 125's.

I have been on KTM's since 2002 but was looking for a change. Found a super clean 2011 YZ 250 in Moses Lake Washington and snapped it up.

Main purpose is riding with my two boys. 4 year old Colton just got on a KTM Mini Adventure after a couple years on a Oset Electric Bike.

The only real changed I did right off the bat was to install some Fast Co Flex bars.

I have not had a 250 2 stroke since 2006, when I had a KTM 250 XC. The power of the YZ surprised me at first. I could see where it could easily get me into trouble once I got tired. The revalved suspension from EVO was magic. The previous owner was close to my size and weight....so it seemed to work great. We reset the sag to 105mm and I immediately felt at home on it. I am way to out of shape at this point to fiddle with much........just need some seat time.

After the first night on it I order a G2 throttle tube and installed it with the 300 cam. Huge improvement.

The thing runs soo good I have not even looked at what is in it for jetting. Runs nice and crisp throughout the throttle range.

Next step will be a FWW I think. I had a Rekluse in the 250F, and it has taught me some bad habits. I am having an issue with stalling it coming into corners. Getting on the brakes before I have the clutch in far enough. Working through that.....but I think the FWW will help the stalling and tame the hit even more.

Really happy with the amount of power everywhere. Bike has a 49t on it. Was thinking a 50t would help me use 3rd a little more.

Thanks guys. Yea when I looked at it in pictures on Craigslist I was skeptical, but when I saw it in person it was the real deal.

Clean and unmolested.

Used to race the NDMA series in the late 80's, get a GYTR flywheel from RM atv/mc best price around and they work great.

Not a whole lot of tracks around back then.

How much weight does the GYTR add?

Coach, what it that on your front fender near the number plate?

It is a Garmin Cycling Computer. Tracks laps times, total time riding, etc.

That is more than I thought. I did not start racing in North Dakota until 1996.

Did a little testing last Saturday......I saw a little because I was having too much fun testing to monkey with much.

First I rode a moto with my existing jetting. Then I switched to:

NECW/3 - Suzuki needle
170 - main jet

Then I realized I did not have a screw driver sized for removing the pilot jet. Crap. I tried the set up with the existing unknown sized pilot. From 1/4 throttle on up it rocked. Traction was prime and I was charging on the track. As the day went on....the track went away and I was getting tired. I was coming out of corners a bit softer and noticed a bit of a hiccup between 1/8 and 1/4 throttle. Not a bod.....more like a surge or pipe bang. I messed with the air screw without any change.

Overall still really pleased with the bike. Adapting well.

After riding my old KTM and a 2017 Husky.....I miss the Hydro clutch......or at least the easier clutch pull. Any suggestions on lightening it up on the YZ?
