Part 6 of the 2015 YZ250FX...As Ridden by 21J

Looks pretty good after all the different rides Doug put it thru!
Looks like Part 6 is going read like a diary I’m going to fill it in as the rides accumulate.
Since the big mud fest CC event I’ve ridden the bike a number of times, at Mammoth Bar again and for the first time I made no adjustments or changes, just rode it. After beating the crap out of myself there I went to Chalk bluff which is very tight single track trails at about 5000 foot altitude in the high Sierra mountains. Made no changes there either and for the first time rode the bike on those very tight back and forth trails, which this day was very wet, snotty, rocky and the trails were full of debris and downed trees as result of recent rain and wind storms. This made for some real technical riding and again the bike worked great. I had a few tip over’s as well and the side number plates now look like that of a year old bike.
The reworked suspension has taken all the twitchiness out of the chassis it’s now very stable and planted and worked very well in those conditions. I’m using the clutch a lot more now especially riding in this area, the bike pulls well even when it’s at lower RPMs but to get it going just fan the clutch a little and it comes to life. But it’s a very controlled coming to life, not a holy shit hang on kind of hit, just starts pulling stronger and since the motor revs to the moon you can leave it in second or third and ride at this place. And again the stock gearing seemed to work very well for these types of trails.
I am going to make one change to the bike before I ride it again. I’m going to move the foot pegs from the back and down position the stock position. Not sure if it’s the peg position or just a new, but I’ve noticed my shoulders are getting sore and I’m not sure what’s causing it. In some ways it feels like I have to reach farther out to pull myself forward or something.
Well I went a mile up the trail and a mile back with the foot pegs stock. It just didn’t work for me, I felt cramped. I put the back and down pegs back on and finished my ride.
Wayne and I went up to Georgetown (El Dorado National Forest OHV Trail System) and put in about forty miles. We thought we had gone a lot further than that, unfortunately Georgetown is now about as bad as Mammoth Bar is, in other words if you want to beat the crap out of yourself go there. Although today we came across a couple of guys who are working on the trails and the parts we rode where they had repaired were a huge improvement. We need to spend time looking for the seldom used trails up there and I know there are some.
The bike was once again great, rock solid did everything very, well the only problem I had was on some slow steep rocky, snotty up hills. I haven’t figured out how to modulate the power yet, I know the bike will lug up those getting the power to the ground without spinning the rear tire but I didn’t trust it (Or what I should say is me) and spun the rear tire loosing traction, thus coming to a complete stop.
I haven’t until today touched the compression settings, but I backed them out and the bike responded in a positive way. The bike feels light and is easy to change direction and flick around; it works very well in the rocks.
I haven’t had any drag races yet to see how it stacks up against other bikes but Wayne has a KTM 350 SX and said he couldn’t gain on me in any of the straight a ways where we could open it up a bit.
The only issue I’ve had mechanically with the bike so far is it’s started puking out coolant; it was good that it wasn’t that warm. I think it might be a faulty radiator cap, I’ll change it and we’ll see.
I went to Georgetown today for two reasons, one to have my first ride on the new bike on those trails, which are more open than Chalk Bluff (You can use all the gears) but also one of my former colleges’ brother-in-law passed away and he was an avid trail rider, the family asked if I would spread some of his ashes on the trails up there for them, which I was very honored to do. Some of the panoramic pictures are in the area where I spread his ashes.
The next day after the Georgetown ride I went to MMX (The sand MX track in Marysville) this weekend there will be a CC event held there. They combine the two MX tracks plus put you through some bushes, sand washes and rocks as the tracks are located right next to the Yuba River. The course will be a little over four miles, so there will be lots and lots of laps.
I installed a new radiator cap and that seemed to solve the coolant issue, but I bottomed the forks enough that I blew a fork seal. My fault, I stiffened up the compression damping but forgot to close off the Air Cells. Off with forks and over to Bucky at SBB to replace both seals before the weekends race.
My intention is to report on this weekend’s CC event and then go to Arizona the following weekend for the first Old Timer International MX race of 2015 and report on that one as well. After that I think you’ll probably have had about enough of me and my stories.
The fourth race in this year’s District 36 CC (Cross Country) series was held in Marysville at the MMX motocross facility. Two of the first four races this year have been held on courses that were a little over three and a little over four miles in length, very short by CC standards.
I had a command performance late Saturday afternoon and evening. My wife had passed her black belt test a few weeks ago and Saturday was the belt awarding ceremony. I dared not miss that if you know what I mean.
I had planned to race Saturday but by the time my race would have finished and I got home desert would be served after dinner at my house and that just wasn’t going to fly. So I raced on Sunday instead, I moved up one class from what I normally race giving away a few years in the process, five or six years at the very least. I did quite well I won by two and a half minutes over second place. My race was an hour and a half of mostly sand and I had enough gas to left to do a couple more laps. The longest trail ride I’ve done (Our trail rides aren’t leisure) was fifty miles and I’m not sure I would have wanted to see if I could make sixty. Hopefully someday someone will come out with a larger tank, 2.9 would be great but because of the electric start and the location of the battery and all I’m not sure if they’ll be able to get one that large.
The course lay out was very good and fun, but the back sections were very, very difficult, lots and lots of soft sand woops and river rocks as part of the course ran next to the river. My arms pumped up the first two laps and I felt like I had used all my energy, but by the third lap I started loosening up and by the end only my knees were getting tired. The bike just doesn’t pull on you and tire you out like a big bore does.
I didn’t change any settings on the bike other than close down the Air Cells and the bike once again ran great, handled great and except for the occasional short run up a soft whooped out sand hill had enough power for me. The rider who finished third overall in the AA class was riding a 250FX a testament to this new bike.
Off to Arizona for first round of the Old Timer International Moto Cross season, with a stop on the way in Havasu to see #33.
It’s a long way from Northern CA to Havasu and after a short visit with #33 it was off to the ACP (Arizona Cycle Park) which is between Buckeye and Gila Bend (Pronounced He-la Bend) and both of those places are about an hour outside Phoenix.
The track is located behind a Federal Prison in a big pit. The pit is big enough to put two motocross tracks and an Endurocross course in it. Since it was in a pit I assumed it would be a sand track but it wasn’t. It did have sand but mostly it was kind of hard packed. It had some nice short up and down hills and I really liked part of the track, but the rest wasn’t what I’d call Old Timer friendly. It was very jumpy and the faces were peaked and valleys between them meant if you didn’t do it right you could be in a world of hurt. (And there were more than a few who didn’t do it right)
One of the things I was curious about was how the 250 would fair against 450’s off the start. The start was a slightly up hill left hander and the first race I got a great jump and was second into the first turn. The second race I stood the bike straight up after the gate, the third race was a mid pack start and the fourth race I was dead last into the first turn. From great to lousy in four starts, that’s progress. Conclusion, I would have to do almost perfect starts every time in order to beat a 450 into the first corner. (Probably not going to happen) The other thing I noticed was in order for me to feel comfortable jumping the jumps I did jump I needed to carry a lot more speed through the corners to make sure I had enough momentum. With the 450 I don’t need to be as perfect through the corners because of the power. Not sure if this feeling was because of the faces on the jumps or if this is just the way it is. (Going to Prairie City and the Hangtown National Track in a couple of days, we’ll see if that feeling carries over) But the 250 definitely didn’t wear me out as much as the 450 and that’s a big plus.
Time to wrap this up, every part or accessory I put on the bike was to help me and they did. There isn’t anything I’d take off or exchange for something else, the goal was not to make the bike better but rather to make it better for me and that I accomplished. There are plenty of riders who could ride this bike totally stock much faster than me.
As I remember in Part 1 I wondered if this bike could give the KTM 250 XCF a run for its money, I still haven’t ridden a KTM 250 XCF but I believe the answer is yes and then some. Except for those occasions when pure horse power is called for this bike can hang with anything.
As I’m finishing up this six part series I now have 21 hours on the bike and Roseville Yamaha has checked the valve clearances and given the bike the once over for me and all is well. There’s really nothing more to say about it, it has far exceeded my expectations.
Once again thanks to everyone at Roseville Yamaha for their support and to Bucky at SBB suspension.
Maybe at some later date I’ll do an update, but until then, this is…. The End.
