Has anyone else had a bike they were emotionally and financially attached to because they decided to keep it a decade past its prime? I imagine I am alone in feeling this way about a 'disposable' mx bike.

Yes, I feel this way about my RV90. I will never sell it. I've sunk tons of money into it for essentially no reason other than I love it. I bought a $400 ignition for it, and the guy from the ignition company told me I'm the first person in the US to buy one for an RV90. I'm that crazy about it.

You take great lines in the rough stuff, you just hop over the worst of it. The elevation looks really fun, too. One of these days...

It looks pretty smooth along the ridge. Are there any switchbacks going down the hill?


Thanks! I'm of the mind that line choice is more important than out right speed most of the time. If I can stay out of nasty stuff I will, but I think it's also good to be willing to just confront a large obstacle and go right over it. This works really well in big rock gardens. You can pick a smooth line for a while but if you see a kink in it because of a good sized rock or something, it's usually easier just to hop over that obstacle and continue on your line rather than to risk the front wheel disruption of turning around them.

The place I'm riding at is kind of different than most of the riding we have around this area. There are two mountain ranges, the Sierra Nevadas and the coastal range. The coastal range is much smaller getting to a maximum of something like 6k feet whereas the Sierras get up to 12k or so. This place is in the coastal range. There is much more erosion, ruts and nasty bushes that like to stab you here. The 'trail' I'm on just sort of cruises along the road and then later on there's a bunch of things dropping down into canyons. There is one huge nasty loop out there that's about 16 miles of all first/second gear with about a million and one switch backs. It's really fun but it will beat the piss out of you.

But anyway, if you ever make it down to California out of your overly wet state, I'd be more than happy to show you some awesome places here.

So the PO has the YZ jetted all kinds of hosed up, so it only wants to run with the choke on. I managed to get it going for a little while earlier without the choke and holy mother of god when it hits the powerband it's loving outrageous. This thing is insane, and it's only a 125.


Bled the brakes, and that helped a little (but not a lot, gonna re-do it later.)
Adjusted clutch cable
Fixed the shift lever to keep it from falling off.

Looks like I might have a leaky fork seal.

Bikes always run the best just before they blow up.

Now that you have the piston off, does the crank move freely?

And if it does, are the crack or the con rod bearings shot?

To test the con rod bearings pull on the connecting rod. It can wiggle side to side but should have zero up and down play.

Taking the left side cover off and wiggle the almost non existant flywheel. If it can wiggle up and down your con rod bearings are blown.

I have minimal experience in engine overhauls, but isn't the mentality "replace all wear items when you're in there?

Would it be excessive to replace all the lower bearings? Is there a concern of debris mucking up the bottom end?

State: Rhode Island (and environs)
Riding: Usually commuting, long riding/camping vacations, weekend "drop-o-ramas"
Bike: for dirt - Honda XL600V Transalp or CT90 for putting around.
Terrain: Whatever comes next whether I like it or not. I don't really do totally "dirt" unless I get dragged into certain situations. I don't mind anything except deep sand and large babyheads - and that's usually because I'm on a fully loaded "big" bike trying to get somewhere.

Anyway, if any of you are around CT/RI/MA today starts the first Pachaug Camp-n-Ride of the year at Mt Misery Campground near Voluntown, CT. Pachaug has a crazy enduro loop (that I've only done a couple sections of on my TA) along with nice dirt forest roads and rural paved roads. We like to camp so it's a great opportunity to hang out with a bunch of welcoming people and ride whatever ride you want (as long as it's legal).

It seems like the bottom end is fine. I didn't take the left cover off, but I did the "pull on the con rod test" and it passed. Should that be sufficient?

Also tell me a good way to get piston pieces out of the engine without splitting the case.

I got a circlip I dropped in their out by filling the bottom end with premixed gasoline and turning it upside down. Came out with the gas.

EDIT: Now might be the time to do a YZ144 kit? Get it ported for more bottom end? It would probably cost only marginally more than replacing what you have?

Open C is full of newbs (me), but like Z3n said, there are always fast guys. In the harescramble format, everyone is on the course, so class only matters for the start and points. Once you're out there you'll end up paced against people your own speed .

So, according to Eric Gorr, the cracked piston skirt means that there was too much clearance between the cylinder and the piston. The "rattling" noise should've given this away, but I just assumed it was normal because I don't know anything about 2t's.

So it was only kind of my fault.

Hopefully this guy buys my boat this week so I can get this crap shipped off and fixed. It looks so sad, sitting in the garage staring at it's little TT-R 125 brother, both broken and in pieces.

I am looking for some opinions on which pre08 250f has the most lowend grunt? My brother will be running my hybrid atv chassis in the youth 200/300 mod class this year, but I don't know enough about the 250Fs to choose a donor bike/motor. 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.

edit: Trying to go Japanese preferably. KTM motors seem to get a pretty penny on ebay.

Really low compression? Rings at the minimum, also want to check your valves. The xr I'm rebuilding right had really low compression and ended up the valves were also shot...but it was a lot older than yours. Note to anyone looking to get a service manual for parts/rebuilds, don't get a Clymer. I see them at every shop, but spend the extra time/money to get the oem repair manual. Ktm, honda, and yamaha all have had good oem manuals so far.

Right now I'm not riding anything. I got whomped by a car which took out the Zeb and had to sell the SV for a car to get me around...since riding around with an arm splint/cast is difficult/impossible/stupid. Since I have to wear this thing another month or so at least, before I can even start physical therapy and since I'm moving to Denver soon, I figured part out the wreckage now and get a new bike up there when I'm ready for it.

I can definitely see myself riding dirt again, if anything street will take me longer to reattempt. I believe, now more than ever, that all the drivers are out to get me. :ohdear:

Yikes!!! Well, glad you made it out alive if not unbroken. :( Hope you heal up quick.

I was going to ride in a race today that they've had posted for months but got something or other in my eye and scratched it or something so it's been bugging me and I don't want to put a contact in it. My goggles aren't the kind you can wear with glasses so I skipped it. The other reason I skipped was because they've had this race posted for at least a month, no schedule at all. Even after multiple requests still no schedule. I know a couple of other riders that are skipping it now due to no schedule.

Bummer is my buddy who txted me asking where I was, I told him who all wasn't going now and promptly got a txt back with "You are all fags", and then let me know the schedule which actually sounds awesome. All classes running individually, 3 lap races. He's running in two classes. I'm sure that kind of setup would have gotten more riders out there, no idea why they just didn't post how it was going to be run and general times for starts. :mad:
