Recommended Posts

Does anyone know when you should get your valves maintenance on a crf 230?mines a 2007 and not sure if it has ever been done with the previous owners?

THe only time I maintain my valves is if I hear them ticking loudly, or making weird noises, or if it's hard to start up. I've had my 230f for over 4 yrs, w/ about 300 hrs run time on it. Have not yet touched the valves. Starts right up on the 1st push of the button and runs like the 1st day I bought it. My suggestion is if it's running fine, and it starts up fine, then I'd leave it alone. One thing I do w/ my 230f is every now and then is I'll run some gas w/ synthetic 2stroke oil premixed @ 80:1 through the engine. I think it helps to lube the valve guides, now that ethanol is mandated to be in the gasoline supply. Keeps the top end lubed up like it should. Reason I use 80:1 isn't by any scientific method. It's the premix gas I burn in my trials bike, and as little as I ride the trials bike, the 80:1 premix I don't use after 2 months gets burned in the 230f.

all you need to do is check them with a feeler gauge. they will get tight with use not loose to hear a clicking noise as they seat deeper in the seats = less to zero gap between the cam and valves... burning oil in a 4 stroke will build up carbon on the valves, piston, ect. not a good idea :confused:... if it gets hard to start then check them :thumbsup: as far as lube for your gas you could use this http://www.jegs.com/i/Red+Line+Oil/816/60202/10002/-1 but its not needed because you have hard seats lead was used to cushion the valves on inpact

I have an 07 as well. Checked mine over the winter and they we're both in perfect spec. I also like to run a bit of sea foam in my bike, also put some in my gas. It not only keeps the gas from going bad, but also cleans any carbon in the motor.

These motors are pretty bullet proof. They do not require valve checking often like a 4 stroke race engine.

I currently looking into buying a crf230 and this is all really good to know. Since im just a beginner its nice to know that ill be getting a pretty low maintenance bike and wont have to worry about the valves to much, hopefully just regular oil filter and air filter cleaning along with some oil changes.

      So I want to fit a Speedo to my stock Honda CRF230F, I know people have fitted the Trail Tech endurance to them but they are a bit pricey so my questions are is there another reliable Speedo or is my best choice to bite the bullet and get the Endurance? My other question is the stock stator for the CRF230F enough to power a Speedo or more specifically a trail tech endurance 2? I fully capable of installing it and splicing the wiring, my question is just can the stock bike support it? Also the Bike does not have a headlight.

      I am in the process of slowly repairing everything on my 230 that had been bought from a farmer and obviously had no love ever in its life. Anyway, as I pull off one thing, fix it, reinstall it and then ride around again, I keep coming back to it not being the most aesthetically pleasing 230 on the planet. I was wondering if anyone has suggestions for sticker kits leave 'em below.
      FYI: I would like to keep it as stock looking as possible maybe even use the sticker kits from the last couple years of motorbike.

      I hate finding awesome deals, but not able to make it happen! 
      I found a complete '05 crf150f that I would love to get for the gf and get running. He wants $400 obo. It's a 7 hour drive though. I would have no problem making the drive normally, but even if he'd take $300-350, it would still cost me about $150 in gas. I can't really justify spending the money at this point in time and that sucks balls! 
      I just had to rant for a moment

      Hey guys, 
      Just  finished my xr and wanted to share some pictures with what I done. I have read a lot of posts on suspension for the xr, so I’ll share my mods.I got a set of dnm hornet forks from my wife on my birthday. With a new front I had to do a conversion on the back-so I went with a Crf150f swing arm that got off eBay. After some machine work in a Bridgeport mill removing 5/8 off each side it fit. I removed extra 1/4 inch to allow for chain alignment so it could be shimmed. The  frame was over drilled to 14mm and had to shorten the bolt by removing the bolt head and re-weld a nut to the stud. The shock is temporary until I figure linkage or direct mount but for now it’s a 11 inch fast ace 1100 lbs with adjustable rebound. Also for ease of service I drilled and taped the swinger and shock pivots with 6mm zerks. The wheels are the stock Crf150f and installed Ebc slotted brake pads. 
      The DNM front forks were a challenge as no bearing combination would work with the 41mm race. I used a set of roller taper stock bearings and shimmed the bearing to the triple stem. Brake caliper had to be modified with a new bracket to use the 240 rotor. Also I have yet to find information to support these forks so if anyone has information on these please let me know.. 
      35inch seat height
      as for the rest of the build the motor has a engines only 120 kit with cam and slotted cam sprocket and mikuni tm24 carb. Shower head and oil pump by Daytona and alto red eagle clutch with bbr springs and a hydraulic clutch. Cdi and coil, new seals. installed a bbr  cradle with engines only aluminum front mounts. Had to remove 2mm off the engine and frame dowels to get these to work together. A new seat cover and foam with a clean up on the plastic. Let me know what you think. Thanks
