    Manual Cam Chain Tensioner Bummer

    Not sure which one you want but: Reach Terry at Miller Vintage Cycle. His web site has his contact info, but he is out of office for now. Shane at SW Air Flow Services is 818-261-7216.

    Manual Cam Chain Tensioner Bummer

    I did get in touch with Terry recently to inquire about another Stroker Crank and it sounds like he will be out for a while. Attached is his message. BTR (Larry) referred me to a guy in CA that does head work and is very familiar with our 230’s, he also can supply an oversized intake valve. His contact info is: Shane at SW Airflow Services 818-261-7216.

    RSW Racing Triple clamp

    I am converting to XR400 forks from CRF150R forks. While I was playing around with the idea of shimming the XR600 stem I decided to try the 150R stem in the XR600 lower clamp, and It fit perfectly. So I have XR600 lower triple, 150R stem, RSW Racing top clamp. No modifications needed, all bolt up and go. Note the XR400 stem has a different diameter stem and will not work with the XR600 triples or 150R stem. Several others are shortening the 400 stem buy cutting and welding, but I didn’t have that option. You can also use the 600 stem by shimming the top and bottom of the clamp. Lots of documented builds on TT. The most recent is titled I pulled the trigger started by BTR.

    RSW Racing Triple clamp

    I just bought a top clamp from Ron, beautiful piece. I am using xr600 triples to mount XR400R forks on my 230, I wanted the 9/8” bar mounts so I bought the rsw racing top clamp.

    Pulled the trigger.

    RM, I used a CRF150R center bearing spacer from a rear wheel, it was plenty long and much lighter. I cut the correct length with tubing cutters to match the 230 center spacer. The remainder was just long enough to use as the right side spacer and was the perfect OD to fit the 230 seal for the right side. Killed two birds with one spacer, saved some weight, and now have a sealed right side. BTW, your shop notebook is awesome. Lots of very detailed information. I wish I was half as organized as you, seems as I get older I remember less and less. The old PD pumper carb I was using recently gave up the ghost so I decided to re-try a real PWK carb. Thanks to your notes and details, the process was seamless.

    RM, please detail the resolution for getting proper number of clicks on the forks. I have my bike fully set up with the XR forks and plan to test this week if the weather holds out.

    Pulled the trigger.

    RM, did you use the 230 front wheel? If so, did you have to modify the center bearing distance spacer as BTR mentioned? I don’t have my parts yet, but was curious if XR center bearing distance spacer was the same as the 230?

    Pulled the trigger.

    Here are some pics of the triple clamp set up. 89 XR600 lower clamp, CRF150R stem, RSW Racing top clamp. I just got the top clamp delivered today and I am very impressed. It has 6 mounting positions front to back, and you can get bar mounts in heights between 1.5” to 3”. I wanted 9/8” mounts so I could use my TE flex bars. RM, I plan to start setting up the 230 wheel soon, I have several spacers ordered and should be here soon. I will let you know the results.

    Pulled the trigger.

    I have been collecting XR400 fork conversion parts and decided to pull the trigger also. I found some pretty interesting things I would like to share. For my project I am removing a set of 150R forks to test the XR400 forks that BTR has been raving about. I like the 150R forks, very light weight, but could not resolve the issue with the tire hitting the frame down tube. Not a bad hit, but enough that it keeps me concerned. Not crazy about adding weight back with the XR forks, but we will see. I thought I had purchased 98 XR forks, but actually got the 96 model. Note that anyone that has the 98 and up forks, you can use the 96 Springs since they are 1” shorter, just add a 1” pvc spacer and lowered 1”. I cut mine 1.25” as BTR suggested, I’m just not a fan of spring cutting. I removed shims from the base valve for a total of 0.24mm and added two to the mid valve stack. I used 3 wt shock fluid 4” from the top. Also new bushings and seals. I bought an 89 RM125 front wheel, spent a lot of time cleaning and straightening it, even put new bearings in. Unfortunately i found two issues with this wheel, the brake rotor is too big and hit the caliper mount. 2nd issue is no seals! The wheel spacers have a metal shield that acts as a shield, but no seal. This was a no go for me even if the rotor would have cleared. I will use my CRF230 front wheel with XR bearings, shortened XR center bearing spacer, and custom spacers to make it fit. I had a significant discovery with the triples. I am using 89 XR600 triples as recommended by RR and was planning to use aluminum spacers on the stem to make it fit. Once I removed the triple clamp from my 150R, I decided to press the stem out and try it in the XR600 clamp and it fit perfect! I ordered an RSW Racing top clamp so I can use my 1-1/8” bars. i am still missing some small parts and still need to turn some spacers....hopefully next weekend I can do some testing.

    Fork Options for CRF230....?

    Redmesa, check eBay for an RM125 front wheel. I mistakenly bid on a front wheel when I was trying to buy the rear, and it turned out to fit the xr400 axle perfect. Look for 88-91, and refer to the bearing chart that someone posted earlier for conversion options. These are much cheaper an readily availably than the other options.

    CRF230F Build

    Piney Woods, I am in south Louisiana so I don’t know what ‘winter’ means either. This is the time I look forward to riding without the fear of heat stroke. I learned several years ago to have more than one bike so I am always ready to ride. Actually summer time is project time for me since it’s too hot to ride. This was the best weekend yet, still 90 degrees but low humidity. Haha.

    CRF230F Build

    Hondo, a few more questions about your build. I experimented with the upside down 230 swingarm bus wasn’t convinced that it was semmetrical, it seemed offset for the sprocket. Any issue here? The 230 piece is much lighter than the KTM I am using, so I really wanted to go this direction. Were you able to find a stiff enough spring for that 85 shock? I looked but didn’t see any available. The ohlins shock I am using is 1” shorter than the 85 shock and has several spring options since it was designed for a full size bike. So you used PVC pipe to attach the carb to the filter? Please give a few specifics on this because I am struggling to make a fit-up. How did you adapt a 20mm axle to the 230 swingarm? i am assuming that is the KTM 85 forks, did you check clearance on the front wheel to frame? I had this issue with the 150R forks on my other 230, it barely rubs now on full compression, not enough to affect safety. I remember woodsryder had this same problem. It is nice to have someone to bounce these ideas and issues around! Keep up the good work, Jeff

    CRF230F Build

    My next project is to transplant a CRF230 engine into this KTM250 frame. Test fitting this 150F motor seems promising, the exhaust header is probably going to be an issue where it exits through the frame. I have a complete rolling chassis for an 06 250F.

    CRF230F Build

    Hondo, looks like we are on the same path. I found a NOS ohlins PDS Shock and then decided to try the 96 KTM swingarm that has the linkage mount through the swingarm vs top mount. I really reinforced the upper shock mount since it is a few inches longer than the stock mount. I have lots of KTM parts that I have collected over the years so that makes it economical for me, also these old KTM parts are dirt cheap. I set the rear up 1” higher than stock and I am going to use XR400 forks so I can match the height in front. That is the only complaint I have on my other modded 230 is the lower ground clearance, it has bit me a few times. This is a fun project and no big deal if it doesn’t work. One question, what air filter and intake corrugated pipe are you using? I can’t seem to locate that pipe.

    Three CRF230 Projects

    Project #3: shoe-horn a CRF230 engine into this 02 KTM200 chassis. I picked up this nice running KTM today for a song and a dance, however I have no wish to go back to 2 strokes again. This project I am very excited about if I can make it work. These chassis are smaller than the newer KTM s, and have a nice plush suspension with more ground clearance than my CRF230.
