  1. I wouldn't have called it a top end cam but a good all around cam. It worked very well. Didn't handle as well as my XR200R but ran great. Probably about 26+Hp at rear wheel. I am thinking real hard at getting a AJP PR4 240 this year. Engine is based off the CRF230. 10cc bigger. 30mm carb with pumper. 5 speed. 3/4" bigger clutch. about 20hp+ stock. A lot more finning. Euro suspension and frame. We had a fun day after the SERA banquet a couple weekends ago and had a PR5 (250cc watercooled with 30hp @ 8000 rpm. And a PR4 240 air cooled to test ride. I am recovering from back surgery right now but a lot of good riders tested both and the results were surprising. Most people were shocked at how good both bikes were. Some prefered the PR5 and some the PR4. Even some who thought they would like the watercooled bike better actually liked the Aircooled bike best. AND the price is right on the entire line.
  2. Honda did fix the early RFVC head bikes by doing away with twin carbs and improved oil pumps and dry sump on 350 and bigger bikes and oil coolers on the 250r. And by junking the 20lb overweight RFVC 200cc engine and going back to the better twin valve 200cc single carb older engine. Early 200 and 250 RFVC bikes with twin carbs got so hot they literally boiled the oil in the heads and engine. Standard petroleum oils would break down quickly due to the extreme heat. Sometimes in less than one ride in hard conditions.
  3. You are quoting someone who raced RFVC Hondas for over 16 years. For Al Baker and Thumper Racing. 4 ISDE medals on modified RFVC Honda XR250Rs. 280, 300, 310 and 315 big bores. I stand by what I said. Stay away from Twin Carb XRs.
  4. I don't have a chart. Lectron didn't dyno my bike. They did another one. BUT, I don't need one. I can promise that a 250 two stroke will not out run it. Mine jumps out of the hole and keeps pulling. I shift as quick as I can grab another gear. Don't over rev. Use torque not Horsepower. Once in 5th gear, just let her eat ! Use only a good synthetic motorcycle racing oil or you will regret it. These engine tend to run hot normally, due to the RFVC head. A lot of moving parts in the head.
  5. I use the manual compression release. I hate the auto one. I pull in the lever and kick the bike through about 3 strokes. Then feel for TDC. Then bump the piston just past that point using the compression release. Let go the lever. NO THROTTLE. Kick hard and follow through. It will not kick back if you are just past TDC and follow through on the kick. Don't try kicking it like a small bore 4 stroke or a 2 stroke. If you fall, use the compression release to unflood the engine by kicking through abouty 5-6 times with throttle open. Then start normally.
  6. I was riding a loam top with a hard clay base. I have a Dunlop AT81 front on my XR440.
  7. What year model is yours ?
  8. Call Lectron and ask for Kevin. He setup my carb and I never had to change the needle it self. Just a bit of fine tuning.
  9. Rode the XR200R at last National. Fell over a bunch due to crappy front tire. Had a Maxxis IT on front. Someone gave it to me. I will give it to garbage man. I am putting a IRC VE35F on it. BUT I am planning on riding my XR440 this weekend at the La. National enduro. Row 1E. I plan on having a good time on the XRE440 but not expecting too much being on row 1 and that I go in next week for surgery on my left knee. I hope it is just cartilage tear. I have been limping for so long now my hip hurts.
  10. Pirelli MT16 front and rear OR IRC VE35F and VE33
  11. If you weigh less than 200lbs then a .40kg is more than enough for a XR250R.
  12. Stock , Rider sag at 105mm.
  13. Way too heavy. Stock front is .41kg. Plenty for most offroaders. If you weigh 200lbs go to maximum oil level with Maxima 5wt RFF. I weigh 190lbs. Stock springs. I set rear sag at 105-107mm. Recommended by Drew. Don't listen to the west coast guys if you plan on riding offroad. Their setups are more for SX / MX.
  14. I once had PowRoll build a one off custom stroker crank and combined with the 430 kit it made it a 441cc. Last year I gnce again got a XR400R and put on a Namura 440 kit 11:1 compression. I used a FMF muffler (mainly for weight). A Hot Cams Stage 1 cam. I like the throttle response and torque of a milder cam. More drive off corners. I have never had a 250 two stroke out pull me down a straight. The milder cam also isn't as hard on the valves and can use the stock valve springs. I don't care for the Mikuni stroker carb as it drinks gas badly. You would be lucky to get 36-38 miles from a tank. Stock carb is 43-46 miles to a tank. I use a 36mm Lectron carb. I can get 48-58 miles on a full tank in a race. Good throttle response too. 48T rear sprocket. 110/100X18 Pirelli MT16 or as of lately I am running a Dunlop AT81 rear in same size. This thing rips. Last 2 H/S with dead engine starts I got hole-shot. Started in 2 gear. Just make sure the clutch is free and down don't release the clutch lever till the bike has started. I love the results on this build. Be sure to run a Kevlar clutch kit with H/D springs. I put spark plug washers beneath those for more preload to prevent clutch slippage. I run Maxima Extra Synthetic Racing oil in 10W40 or 15W50. Dwight Rudder
  15. Saddly, I didn't fair so well this weekend. I guess not riding for 3 months had a bit to do with it. I think the XR440R rode me more than I rode it. Just out of shape. I kept crashing at least once every section. I am missing spokes in the rear wheel too. I also was wearing a new pair of boots and ripped the side out of my right boot. I have a cut on the side of my foot too. Once I fell going over a log and knocked my gas cap off wasting gas and soaking myself. Sometimes I would be going good then I would just lose it. Oh, Well. You have to blow the cobwebs off somehow. If I can't get the spokes intime I will be riding the XR200R next weekend.
