I'm contemplating it but haven't made a final decision yet. Have a few buddies going that keep trying to sway me. They will definitely tame the track down, shallower whoops, smaller finish line jump etc. I'll keep an eye out for ya if I make it up!

2 strokes are making a come back no doubt about it. Hit the open practice at elizabeth city this past weekend and the amount of YZ250's and YZ125's was unreal (decent # of KTM's too). Everyone who jumped on the bandwagon 5 yrs ago is finally seeing the ... more »

We have ignition! It was indeed the stator, and I have a theory on what happened to it, but I'm embarrassed to admit my brainfart

Anyway, I'm running on 93 mixed 40:1 right now and want to make sure it's not detonating. I obviously don't know ... more »

I did the ohm's test on the coil as shown in the manual, results were within spec:

Then I did the source coil tests and got no reading for source coil 1: I then put the leads directly onto the stator where the black and black/red ... more »

Been going through all the Ignition tests in the service manual. I'm getting no reading for ignition coil 1. Is my stator shot?

I wouldn't think that would just randomly happen during a rebuild. Dammitt I need to go riding this weekend!

That'll be the first thing I do. I'm gonna feel like an idiot if it's this, but I need to make sure I have the plug wire on all the way. I feel like it was on but i didn't feel a distinct ... more »

Got the engine back together and it won't start, I feel like such a newb! Granted, its been 3+ yrs since I've done my last rebuild. Almost seems like it's not getting any spark, like it won't even try to start. To summarize, cleaned carb and installed

Who all's training under him? I know he's been mentioned a few times in the broadcast but can't recall the riders...

So that'll put me right in line with the 2011+ bikes, cool. I can literally see the local airport from my house and they have 100LL, just need to confirm accessibility. Good to know it's there so I can go that route if I need to.

I think I will throw a 50 and 180 in the carb and mix premix 40:1. That should give me a safe starting point. Then do a pressure test to determine if something other than jetting (crank seals?) was contributing to my lean condition. I'll have to decide ... more »

What 100 do you run? I have an airport literally half mile from my house. Might look into picking up some 100LL, seems some people have used it with great success.

I put in a parts order last night and picked up a stock pilot, wish I would've seen this sooner and I would've got a bigger main too. Which pilot would I be better off starting with 48 or 50? Definitely planning to reseal with all new gaskets and I found ... more »

I'll dig into the carb and get some pics of the piston this evening. Not sure on the jets since I bought the bike used. Is there a way you can differentiate between lean jetting and lean condition caused by a leaking crank seal (based on observations ... more »

I think the o-ring got eaten away as the pitting propogated towards it...definitely didn't help things once that started happening. Good thing I tore it down when I did instead of continuing to ride. I'll definitely keep an eye on things once I get it ... more »

I just ordered a dial gauge so I can get the timing spot on. Powerseal also said they'll cut .010" out of the head squish. Between those and a new crank seal I should be good. Thanks!

Added reply in a thread YZ250-Extreme Pitting Problems 1/9/2015 8:48 AM

I have heard these engines can be finicky on pump. Luckily I have the cylinder and head at Powerseal USA for repair right now, I'll see what they can do with the head to fix the sqish gap. Thanks!

Hoping you guys can give me some insight into this! 09 YZ I bought last Jan, Did a top end this summer after it started losing power/compression. Noticed some slight pitting, thought maybe it was detonating due to pump gas and advanced timing so I set

I believe he hit a tuff block in the whoops and ate it pretty hard. Didn't watch long long enough to hear how he was afterwards.
