    2016 TTR 230 Suspension

    The springs on the stock bike are extremely frustating. The back is over-sprung at 8.34 N/mm and the front is under-sprung with a variable rate 0.34 - 0.48 kg/m spring. The 0.34 is way too soft and the front end dives and sits to far down in the stroke. The rear spring does not effectively use its available travel. I ordered from Cannon Racecraft and installed a 7.0 spring on the rear and a 0.44 spring on the front. I use 20w fork oil with the oil level set at 160mm. The rear sag is set at 90mm. These springs and settings work well for a 180 pound rider at reasonable trail speeds. The TTR suspension will never be a race suspension but these improvements make a significant improvement in the handling for trail riding. The springs rates are balanced front to rear and allow both ends to be reasonably firm while allowing a reasonable use of suspension travel.

    2005 YZ250F Throttle Position Sensor, Please Help me?

    The TPS when removed from the carb will go "over center" if turned and when in this range it gives one constant resistance reading. Use a small flat bladed screw driver that will fit the internal TPS slot. Carefully turn it 90 degrees or so until you can feel it snap back over center. Now you need to test it by turning it no more than 90 degrees similar to the range of motion that you can observe on the carb shaft going from closed to full open throttle. The resistance closed should be around 200 ohm and the resistance fully open should be around 5,000 ohms. If you get readings in this range, then remount it on the carb shaft carefully making sure the slotted shaft mates up right with the TPS. Tighten the retaining screw in a mid position and retest the resistance closed and fully open to make sure that they are changing. The values will be somewhat different than when off the carb because the range of motion is less. If the resistance changes checks out on the bike and when open and closing the throttle, then adjust the final position and voltage per the manual. A TPS adjustment tool is pretty handy. It will hold the meter leads much easier. You should be able to locate one with a quick search.

    Will a 120/100-18 fit on my ttr230?

    I have had a Pirelli MT43 4.00x18 on our TTR230 and it was a tight fit that required an extra link in the chain and the axle all the way to the back. It still wore a hole in the mud flap. I would be surprised if 120/100x18 would even fit. The 100/100x18 is the ideal tire size for this bike.

    The Nature Conservancy

    If public money was involved, then it should be no less than 50/50 motorized/non-motorized in order to meet equal opportunity requirements. More than 50% motorized trails can easily be justified by actual use.
  5. Has anyone found information on the transmission and primary drive ratios in the new 2015 WR250F?

    valves VERY tight. rfs motor

    Here is some good advice from one of the RFS experts on the forum "loosen the right intake valve adjusters jamb nut and see how many turns outward it will make before its bottomed out. Valves should be changed when there is 1.5 to 2 turns remaining, going further and the adjuster cannot wobble to fit the angle of the valves." This guidance turned out to be very true when I replaced the stock valves on my 400 with Kibblewhites. The intake valve faces was worn to a knife edge and was ready to split. I could never go more than 20 hours on the stock valves without an adjustment. If I went 30 hour, then the intake clearance was just like yours. With Kibblewhites all the way around the valves can go one year between adjustments. I replaced the stock exhaust valves also because they were pitted which might be due to the gas formula that we have now days.
  7. Yes, the seats checked within spec and had the orginal marks on them. My bike is babied with regular oil and air filter changes plus it is not revved. I ride low to mid-range which is what makes this engine so much fun. Just put another 50 miles on it today. Every bike is going to be different so be sure to check the seats out closely. The stock needle is pretty lean which causes the engine to run hot. The JD needle is a great improvement. A lot of my riding is at less than 20 mph on trails with long climbs. A needle change was not enough to cure the boil over for me. If you are riding with more speed you may not have a boil over problem. I tired quickly of the boil over issue and put on both the RLR overflow tank and KTM fan at the same time and have never had an issue since. The fan comes on quite a bit. I am pretty sure that just the fan would fix it. It needs some extra air flow at low speeds.
  8. I have this exact bike with 9000 miles on it and all of them have been fun. Plan to keep it another 9000 miles. Have only done one top end rebuild and added the Kibblewhite valves at that time. The valve seats are extremely hard and were in perfect shape when I did the valve job. Now instead of adjusting the intake valves every 20 hours I can go a whole year. If you ride challenging trails the smooth torque from this motor is a great combination. They tend to run hot and the JD jetting will help but if you ride slow trails in the heat you will want to add the KTM fan kit in order to avoid the cloud of steam when it boils over.
  9. The Gallatin National Forest has been through the travel planning process. A lot of trails were closed to motorized. There are still a few open. You will need to study the motor vehicle use maps (MVUM). They can be downloaded at the Gallatin National Forest web site: http://www.fs.usda.gov/wps/portal/fsinternet/!ut/p/c5/04_SB8K8xLLM9MSSzPy8xBz9CP0os3gjAwhwtDDw9_AI8zPyhQoYAOUjMeXDfODy-HWHg-zDrx8kb4ADOBro-3nk56bqF-RGGGSZOCoCAPi8eX8!/dl3/d3/L2dJQSEvUUt3QS9ZQnZ3LzZfMjAwMDAwMDBBODBPSEhWTjJNMDAwMDAwMDA!/?navtype=BROWSEBYSUBJECT&cid=stelprdb5130574&navid=360000000000000&pnavid=null&ss=110111&position=Not%20Yet%20Determined.Html&ttype=detail&pname=Gallatin%20National%20Forest-%20Maps

    Wireless bicycle speedometer

    I have tried to use a wireless bicycle speedometer on a Yamaha and it did not work. The ignition interfered with it and rendered it useless. The wireless unit is extremely sensitive to electrical interference which is not a problem on a bicycle. I have used a Cateye Enduro with a wired lead successfully on two motorcycles for a number of years. This may require some lengthening of the leads with appropriate wire and some careful soldering, mounting the sensor on the brake cover and using JB Weld to glue a magnet onto the front brake disk in the appropriate spot (just below a mounting bolt). I also use a GPS and the difference between the Speedo and GPS mileage is usually within a mile or two of the speedo.

    Looking to buy a '04 400EXC

    Because of the lowered rear suspension the chain may be closer to the "tight" spot in the swing arm travel. Still be sure to check the hub and output shaft bearings to make sure that they have not run it with the chain too tight. We have had a number of TT225, XT225, and now a TTR225 in our family. I ride a 2004 400 exc just like this one. You won't believe the difference in handling (about as good as it gets in the sand) and power (smooth torque that is an absolute blast for trail riding). I personnally rate the KTM 400 and the WR 250 as the all-time great trail bikes. I would question the lowered suspension. Unless you are vertically challenged, I would have them restore the suspension height. I am a little vertically challenged with a 32" inseam. My suspension is stock with the sag set on the low side and EE soft low seat. It is quite manageable for seat height. If you are taller, then definitely restore the suspension travel.

    Primary Drive at RMMC?

    I am using the RMC 53 tooth steel sprocket on the rear and the 13 tooth front sprocket on the front. Both have worked well and are reasonably tough. A word of caution however, the spline portion of the front sprocket is 1 mm too thin (7.5 mm versus 8.5 mm stock) and it will leak oil. You can make it work by purchasing a 1 mm thick by 25 mm ID by 32 mm flat washer (machine washer) at your local hardware or auto parts store and placing it immediately behind the sprocket. This will make up for the missing thickness but given the hassle I would recommend getting a stock front sprocket or a brand that for sure has the 8.5 mm thickness.
