  1. I can't speak from personal experience, but the guys at Moscow Motorsports (I think it used to have a different name a few years ago) recommended some locations near Elk River (or was that Elk City?). While searching for more info on Elk River, I found this: http://www.everytrail.com/browse.php?activity_id=38&country=united+states&state=Idaho That might give you some ideas. Due to circumstance beyond my control, there will be no riding in Idaho for me this summer. Have fun and be safe.

    Whats in my oil filter? **PICS**

    Are those chunks or more like a powder? Metal chunks are not good. Clutch material tends to be very fine.

    New to me xr50

    For oil, I use Castrol or Valvoline motorcycle oil or Rotella. Last time I looked, the Castrol and Valvoline motorcycle oils were about $5/qt and Rotella was about $3.50 if you buy it on sale in the 1 gallon container. If you use an oil made for autos, make sure it's not "energy conserving". Wet clutches don't like it. When it comes to the oil change interval, sooner is better than later. Transmissions are very hard on oil. Also, most people won't be good about checking the oil level, so it's better just to change it frequently before the level gets low. At $5 / qt and only about 1 quart capacity, it's not going to break the piggybank. I don't put more than about 10 hours on the oil. That's just me. But think about it - you won't be spending much on oil. Keep an eye on the swingarm pivot bolt and the steering head bearing. While the motor may be bulletproof, the steering head and swingarm won't hold up well if the bike is abused by big "kids". Honda went cheap with these things. Keep an eye on the rear shock. They don't last forever and if the shock is blown, the swingarm might be cracked at the shock mount. And just because something is "bulletproof", it doesn't remove your obligation to maintain the bike properly. I'm sure someone here will say that his uncle Bob has never changed the oil on his kids' XR50 in 20 years (I know the XR50 hasn't been around that long) and it runs just fine, but that bike either never got used or it burns so much oil that there's no need to change it because you're always putting fresh oit in to keep it at the proper level (assuming uncle Bob checks the oil level).

    Don't forget about the southern hospitality. As far as riding, I hear there's riding about 40 minutes from the plant. Not sure what it's like, but I'm sure the riding season is longer than it is here.

    I hear the parking and weather are better in Charleston. I'm sure the drivers are better, too.

    Smoking 88 Kit

    I feel your pain. I had the misfortune of buying a Z50 without oil in the crankcase (no wonder why it didn't smoke when I test rode it - I'll never trust anyone who says their bike is "well maintained"). Anyway,that lead to a complete rebuild and due to some overlooking of things (bearings), I'm back into the cases for the second time. At this point, it's not about economics. I will NOT let this bike win. It's like my Honda Accord. It's given me a nothing but fits since I bought it and it's trying to beat me into submission, but I'm determined to win or at least have it last long enough that someone plows into it and totals it. One thing I do when putting an engine together is leave notes on blue painter's tape on the motor for critial things. I leave the spark plug out until all the blue tape is gone. It's my verion of those red flags on the landing gear lock pins that say, "Remove before flight".
  7. Something to think about before you do this: make sure that Jr. can start the bike reliably with the kick starter. Four strokes are harder to kick over than two strokes. My kids had a heck of a time getting the 50, 70 and 80 started by themselves. They don't weigh much for their size and while they could get the kick starter through the full stroke, they couldn't spin the engine fast enough to get it to light off in most cases. .

    2001 TTR250 possible CDI issues...

    Assuming this is like my TT-R230, in order to energize the starter solenoid, the main switch has to be ON, the start switch has to be closed and either the neutral switch or the clutch switch has to be closed. I don't see how the CDI would come into play except that it would kill the motor if the kill switch were acting up. It doesn't look like a bad CDI would affect the starter. Since power is always applied to the solenoid when the main switch is closed, all it would take is a short in the solenoid to turn the starter. This could be either a short to ground on the coil or the contactor shorting. You could disconnect a solenoid coil wire (make sure not to short it to ground) and get the bike hot. This is no different than having any of the downstream switches open.Then see if the starter wants to engage. If it does, the short is across the contactor. If not, check the continuity across the solenoid terminals. If you have continuity there, then the solenoid coil is shorting. Get the manual so you have the wiring diagram. Your TT-R250 circuit could be different. But, once you see what's in the circuit, you can isolate the problem correctly.

    TTR50 Electric Start Problems

    Did you drain the tank and give it some fresh gas after you bought it? For the starting issue, are you sure the battery is good? Frequently, a battery will show good voltage, but as soon as you put a load on it, the voltage drops significantly. Monitor the voltage while you try to start it. Your normal DMM may not be able to see anything due to the slow update rate, but you might be able to see it on an analog meter. How did you check the connections? Did you just do a visual or take them apart and clean them? The latter being the only way to assure the connections are good, no matter how good they look when connected. I've learned that more than once. The other thing you can do is measure voltage at different points in the circuit to see where you might have something (connection, relay, etc.) that has a high resistance. For example, measure at the battery while trying to start. If OK, measure at the next connection. You want to make sure input and output are pretty close to the same value. Make sure all the grounds are good - take apart and clean. As always, you'll get the best information on how to solve this problem from a genuine Yamaha shop manual. They're not that expensive. There's no substitute for proper documentation (wiring diagrams, etc.). Don't be tempted by the other non-Yamaha manuals out there just to save $10.
  10. I went through the same kind of thing when my kids were starting to ride, but they were relatively timid so I kept them on a smaller bike to avoid them getting too discouraged. Throttle control was the biggest challenge for my kids. It's tough to say in your case. I can't offer a right answer, just some things to consider. The Honda XR/CRF50 is about 2 inches taller but 25 pounds heavier. How big is your boy? It sounds like capability won't be an issue. I know that this might be hard to do (given how kids can jump to conclusions) but I would see how he fits on one at the local dealership. It would be a judgment call on how well he could handle the extra weight. If you plan on moving him up to a 50 eventually (as opposed to skipping the 50 and going to a 70), pick a used one up if you can find a good deal and hold onto the PW. Then, if the CRF is too much, he can go back down to the PW. I can't speak to the power difference between the two bikes, though, so maybe size is the only issue you need to consider. Anyway, some kids like a challenge while others don't like to be too challenged while they're trying to figure out how to ride. At 4 years old, your boy will improve quickly if he rides farily frequently no matter what he rides. I think the four stroke motor might be more of an issue when it comes to kick starting. Generally, kids young enough to fit the bike aren't quite heavy enough to kick it over and get it started reliably. That's based on my observation with my kids. Kids that are more motivated and bigger may not have this issue.

    Methanol instead of gas in a TTR 125

    Methanol has less than half the energy content of gas. You'd need a gas tank twice the size to go the same range, assuming efficiency is the same. It should be roughly the same. You can get around this somewhat by running higher compression to take advantage of the higher octane. Methanol is also corrosive so you'd need to deal with that effectively or you'll have bigger issues.

    04 CRF50 high rpm bog?

    Thanks for letting us know how the story ended. 9 times out of 10, it's something simple. A dirty air filter is an indication that the prior owner didn't put basic maintenance at the top of his list. At a minimum, you should check/adjust the valves, change the oil and clean the spark arrestor screen. It was running rich with the dirty filter. This will contaminate the oil and plug up the screen.

    04 CRF50 high rpm bog?

    Whenever I get a used bike, I assume that no maintenance has been done. Unfortunately, this assumption has turned out to be true more often than not, no matter what the seller says. Even "bulletproof" engines need maintenance. Proper maintenance is what keeps "bulletproof" engines from breaking. Anyway, if the bike has any issues, I do all the maintenance before trying to troubleshoot. This includes: valve adjustment clean the air filter replace spark plug, or at least check the plug and set the gap drain the tank completely (remove the tank to do this, it's easier) and fill it up with fresh gas clean the spark arrestor screen change oil clean the carb thoroughly Give that a shot and see where it gets you. If you have the problem still, post back with more information such as throttle position when the bog occurs, what carb you have, jet sizes (make note of them when you have them out while cleaning the carb), needle clip position, any other mods, etc. Good luck.

    02 ttr 125 clutch aint right at all. Hope yall can help.

    Usually, you measure clutch lever freeplay and adjust the cable as necessary to get the required freeplay. I've seen freeplay measured two different ways: at the end of the lever and perpendicular to the bars, and between the lever and the perch (for lack of a better description).
