    CRF230F - CRF250F specs
  2. If part assembly #10 slides out from the hub, then it's an L. If the axle has a pull tab, then it's an R.
  3. Go here: https://www.rockymountainatvmc.com Click OEM Parts and find the parts page for your 1991 XR250R. Click on "Rear Wheel 90-91" Check the parts shown against the ones you have on hand. The hubs look identical. I think you'll see that you do have a 1991 XR250R or equivalent. Order 8 spokes, 4 each of: part #8 and #9. When they arrive, trial fit them, 4 on each side, evenly spaced around the rim. Snug finger tight. If they look okay, order the rest of the spokes and go for it.

    CRF230 Shifting 1st to 2nd problems

    I read several reports that the problem is fixed by replacing part #9, the spindle. http://rickramsey.net/CRF230Fmods.htm#shiftingproblems Do a Google site search - I found several good posts: "site:thumpertalk.com CRF230F spindle" Here's one, for a 150, but probably very similar or the same as for 230: https://thumpertalk.com/forums/topic/700337-replace-gear-shift-spindle-on-crf150/

    Do a Google image search for 'Honda CRF250X ADR wiring diagram' and Bob's your uncle.

  8. The way I heard and understand it: The Honda XR250 was made by Honda starting in 1979, and the XR250R starting in 1981. The decision to bring the XR models to the US was made by American Honda in southern California. The US market was growing by leaps and bounds. Al Baker did development work on the XRR models. He was under contract to American Honda, but also had a private business named XR's Only. I think his designs were passed from American Honda back to Japan where the bikes were built and distributed. I assumed that when the CRF series was introduced in Japan and Brazil, American Honda again made the decision to bring them to the US. Al Baker was gone, so Japan was the primary design source. I think that Brazil and Japan designed the CRF230F jointly. XRR's and CRF's are sold in many countries around the world. The US models have always been slightly different than the Japanese home models, as well as those sold in the UK, Europe, Australia/New Zealand, and Pacific Rim countries. The primary differences relate to EPA emissions and DOT safety equipment requirements. The CRF230F sold in the US is made in Brazil. The frames and plastics and other parts are Brazilian made, but most of the nuts/bolts and small hardware are made in Japan and imported into Brazil. I'm pretty sure the engine cases, cylinder, head, and valve covers are made in Brazil. The parts labels indicate country of origin. I have not made an extensive nor accurate survey; only recalling new parts that I've ordered the most. So Honda dealers get their CRF230F parts from Honda warehouses, which get their parts from Brazil and Japan. The dealers get their CRF230F motorcycles from Brazil. The CRF250X/R and CRF450X/R and newer models are made in Japan. So why do we get the CRF230F that is different than the Brazil model, and why is there such a variety of CRF230F models and aftermarket specialty models in Brazil? I think it's down to American Honda and the almost rabid Brazilian fascination with the CRF230F, and now the CRF250F. Economics drives American Honda; enthusiasm and possibly a cheaper labor market drives Brazil and aftermarket Honda. IMHO YMMV

    CRF250F Pics and Mods

    Small gas tank: check Heavy: check Less ground clearance: check Stupid shrouds: check Folding-tip brake pedal: check. NOT Rear disk brake: big deal! NOT Notice that the engine case has casting for oil lines for an oil cooler. So where are the oil lines and oil cooler???

    You missed the point. Click on the link to see the 244 lb HONDA: https://powersports.honda.com/2019/crf250rx.aspx#specifications
  11. You have an XRR carb plus exhaust mods, so just use XRR jetting and go up 1 size on the main and pilot, and maybe 1-clip position richer on the needle. http://rickramsey.net/XR250R.htm Scroll down to the jetting panel. You'll have to choose between 95 and older vs 96 and newer depending on what year the carb is. Carb notes here; differences discussed: http://rickramsey.net/XR250Rcarb.htm If in doubt, go rich and work your way down.

    Gunnison Colorado trail riding.

    I decided to try adding trail names to the BrushCementSpring map that I posted previously, so I got the current version of the MVUM and added names. Here is the result. When you download the map (right-click and save), it will be 1190 x 900 at 144 ppi (8.26" x 6.25") and will print nicely on 8 1/2 x 11 and 11 x 17 paper. I selected the paper size, then scale to fit in the printer setup. Of course, you must have the proper size paper in the printer. The map seemed a little busy at first, but I soon got used to it. It's handy to have the names and numbers together. BTW BrushCementSpring is short for Brush Cr Rd, Cement Cr Rd, Spring Cr Rd.
