From the scoring on the piston, I'm guessing the cylinder doesn't look so good either?

Our only real constrains are left side drive and it can't be a dual exhaust system like the CRFs since we trying to save cash and run stock exhaust if we can route it. http://www.motorcycle-usa.com/11/370/Motorcycle-Article/2007-250F-Motocross-Shootout.aspx Looks like Kawasaki might be the way to go.

JP Money posted:Do you have hilly terrain or just flat woods? I never minded having a 250 2 stroke in the woods even. I feel a lot safer knowing the bike has the power to make it up hills and whatever else you throw at it versus an underpowered bike you don't have confidence in. Riding my 250 4-stroke, the only time I've ever not had enough power was trying to pull 4th+ gear wheelies on fire roads. 35Hp is enough power to make it up any hill you can tackle without an extended swing arm. Torque is another matter, you may need to slip the clutch a bit to make a slow climb. Also, it works, but I had no idea how much my MX bike blows in the woods until I rode it back to back with a 450XC-W. Edit: To be clear, I'm not saying you shouldn't want more than 35HP, I'm just saying you don't *need* more to make it up pretty much any trail.

I tried really hard to get Spiffness back for all those times he splashed into a puddle next to me by jumping into a giant puddle right next to him at high speed. It ended with me and my bike very soggy, and Spiffness dry and laughing. In retrospect, choosing a 20x60ft 'puddle' in the 4x4 area for this prank was probably not a good idea. It stalled before it went under, but it hydrolocked as I tried to kick it back to life. I wasn't able to get the spark plug out and clear the cylinder until the next night because, in their wisdom, KTM decided not to make enough room for a standard spark plug socket, so I had to grind one down. It's much easier to start now without a combustion chamber full of muddy water.

That will do it, a brand new bike can be pretty hard to kick over. He's going to change the oil before he rides it again right? Speaking of... my 250sx-f has gotten pretty easy to kick over, and pretty hard to start. I was looking at ordering a new piston. The Vertex aftermarket piston says it goes in an 2006-2012, but the CR went from 12.8:1 to 13.2:1 in 2011. It could be that the piston didn't change, but I'd rather not inadvertently lower the compression. I guess Vertex should know though, TT says they make the OEM piston too.

velocross posted:Have you checked your valve clearness lately? I'd take a look at them if you're going to change the piston. What year sx-f? I've been using CP pistons in the last 2 KTM's I rebuilt and really liked them. Yeah, I did an adjustment first. It's a 2011. Bad info on the OEM piston, it's an Elko. Right after I figured Vertex probably know what they're talking about and ordered the stock replacement piston, someone responded on thumpertalk to confirm that I need to order the high compression piston.

BlackMK4 posted:Thank you guys I would recommend a 250 four stroke for trail riding, 2-strokes are lighter, but have less usable torque, and get worse fuel economy. If you do get a 2-stroke a 200 or 250 with a heavy flywheel weight works pretty well off road. I started on a 125, it really is a lot harder to ride than a 250F. You need to ride the clutch on slow climbs because its either bogging, or spinning the rear tire otherwise. Range depends on a lot, riding style is a big factor, as is the terrain. You might be able to ride trails for 5 hours on a tank, and burn through the same tank in 40 minutes out in the sand. Edit: Actually at $1500 I would get a 2-stroke.

Kony Kid posted:you weigh like 140 soaking wet. For you a 350 would be a nice trail bike... not so much a race bike. 250 XCF-W 105.5 kg (232.6 lb.) 350 XCF-W 107 kg (236 lb.) 450 XC-W 111 kg (245 lb.) Plus 14 pounds for fuel. The 350 splits the difference pretty well, but it's closer to the 250 in weight than the 450.

Silver posted:Yeah looking at next bike to be a 250XC or Beta 250RR. Mighhhhtt go with a 250XC-F but not positive on that yet, going to ride them back to back soon I think and see. Why the XC over the XC-W? IIRC the XC is basically the same as the SX with a slightly larger fuel tank. The XC-Ws give you a 6th gear, softer suspension, and wider ratios.

VTNewb posted:Looks like a psudo-local dealer has the following: I know the XC is a 5-speed, does it have the same ratios as the sxf? If so, that's probably the most important difference. I guess you don't do a lot of 100mph desert riding, so the wide ratio 6-speed may not be a big benefit. I get a little tired of rowing through the gears, but I have the old close ratio 6-speed.

I went to MX practice today and finally cleared the triple I tried in the race video I posted last week.  I was pretty much blind coming up to it pacing another rider as he roosted the poo poo out of me. Felt pretty good to finally make it, the next try I didn't get enough drive and cased it again.

Messed around with the high speed settings on the GoPro 2 at MX practice today. Sure would be neat to record at 240fps with the a Hero 3 Black. https://www.youtube.com/watch?v=YijtRdj69oc Also, Youtube's compression totally butchered that video, might have to start using Vimeo. Well that explains it, it kind of looks like Youtube didn't like the aspect ratio, so it stretched it out.

Pretty poor showing for me at my MX race today. 1st moto my fuel line dry break fitting partially detached. I was down two laps before I got it fixed. 2nd moto I got my tire caught on the gate, then wiped out six seconds later trying to make up ground and running out of talent. I knocked the wind out of myself and hurt my hand. At least I didn't break it.
