Just bought new (to me) CRF230

Hi guys, just wanted to quit lurking and get some answers to some of my questions. I just bought a 2005 CRF230 from a kid a few miles from me. I can't even ride it yet b/c the back tire is toast, obvious burnout. Anyway, this CRF was bought at a REALLY good price but was not taken care of very well at all. All of the issues are minor and the engine runs perfect.

Here are the problems:

1. Stock muffler has had the baffle removed and is very beat up (I doubt he rejetted either) but hopefully no damage has been done. Heat shield also missing from the header pipe.

2. Fork boots are torn and a fork seal is leaking.

3. Needs new grips.

4. Needs a couple of missing bolts.

5. Tires are completely shot.

6. I'm sure the normal maintenence stuff has not been done.

Here's what I plan to do fix it:

1. Call and see if he still has the baffle/spark arrestor insert and heat shield (doubtful). If not, I'm going to try to find a stock exhaust. I have a "wanted" ad placed on the classified area of this site. If any of you have a stock exhaust in good shape left over after putting on an aftermarket pipe, please send me a PM.

2. I need new fork boots. I'm having trouble finding what I need and I refuse to pay the obscene amount for OEM. I don't like the look of seal savers and will have to find a set of boots. If anyone knows where to find boots that fit, let me know. I'm also going to replace both seals and go to 15 wt. fork oil and pvc spacers. I'm about 200 pounds without gear and need to stiffen up the forks to keep from nose diving.

3. No brainer.

4. Easy enough to find.

5. Already ordered and will be put on next week by the dealer. BTW, I will get them put on this time, but next time I want to build a tire stand and get the motion pro tools to do it myself. I think it would be good to know in case you ever HAVE to do it yourself.

6. Oil change with 10w40 Valvoline MC oil. Clean centrifugal filter. Clean or replace air filter. Check spark plug gap and condition. I've already cleaned and lubed the chain and the sprockets look fine. Front brakes still have life left in them and the rear drum feels fine but I'll know more after riding it. Anything else I need to check or do at this point?

All that said, I bought the bike for a song and can afford to fix it up. I plan to use the bike for trail riding and just general fun. I'm 34 and grew up on dirtbikes, but haven't had one since my CR125 I had in the mid 90's. I've been focused more on streetbikes since then, but dirt riding is in my blood. I think this bike may be perfect for me and the type of riding I plan to do. I ordered a service manual and should get that next week. It kills me for the bike to be sitting in the garage and I haven't even ridden it.

This is an awesome site and I've learned a lot from reading through the forums here. Thanks for any help you guys can offer up.

Welcome to the site bogey78

Just a few things I would do since you don't think the bike was maintained very well.

1 While the wheels are at the dealer having the tires put on have them check the spokes and make sure the wheels are straight and true.

2 While you are working on the forks clean and grease the steering head bearings.

3 Remove the rear shock and linkage and swing arm inspect and grease all the pivot points.

4 Have fun. :ride:

Welcome to TT. Sound like your bike needs a little TLC. The 230 with normal maintenance is avery reliable bike. My 03 hasn't cost me a dime other than normal maintenance. With the service manual you can do most of the maintenance yourself.

Get her done and enjoy.:ride:

btw for tire changes you don't need a 'stand' or anything

just a couple motion pro tire spoons that run $5-$10 a peice, and a bottle of soapy water..

After a little practice you'll be able to swap tires out in 10-15 minues including the time it takes to get it off the bike

why not just upgrade the exhaust? a lot of the stuff that people said above me is good to do. Welcome to TT :thumbsup:

Thanks for the suggestions guys. I will have the service manual in a few days and will read through it and get started on this stuff. I have never checked the steering head bearings or the swing arm or rear shock. I'll definitely get to know this bike well over the next couple of weeks. I really feel like this is going to be a great bike for me.

I'll update when I take my first ride.

what kinda riding u gonna do??

putt-putting and chasing the kids around?

single track?

either way u will have alot of fun with this bike.

i love the saying: "It's alot more fun to ride an underpowered bike wide open than it is to ride a bigger bike at 1/4 throttle." :thumbsup:

o and welcome to TT :)

Thanks Buddy. I guess I'll do a little putt-putting around and some mild to moderate trail riding. Limited jumping and basically just having fun.

Thanks for the welcome. Tires should be in this week and I'll be up and riding soon.

then this bike will suit you perfectly =]

If you are going to have the forks apart to do seals have you thought about a set of springs... You mentioned some limited jumping... we have had several 230's and 150's... and new springs help alot in the trail riding and jumping arena. The stock springs are pretty soft and bottom easily.

I sold all the 230's and have an extra front and rear set I would sell for $110 plus a few for shipping.

Anyway.... let me know if you need anything.

I actually thought about springs, but I just bought some 15w fork oil and plan to add a pvc spacer to stiffen it up a bit. If I need more, I'll go the spring route. Thanks for the offer though.

Not a problem... They are just sitting... good luck with your project.

Maybe he doesn't want an obnoxious sounding exhaust just to get that extra HP or two.

Have fun with the bike!

Mike, you're right. I would probably just leave the baffle out and re-jet if I wasn't worried about the noise. Also, aftermarket exhausts are not cheap, but I am:)

I basically want to get this bike back to stock form and then I'll go from there. My tires should be in today, so I'll have a first report of the bike very soon.

:applause: Amen to that. :thumbsup:

yes i know there not cheap. but defenetly not obnoxious. sure itll be louder but it'll sound niiice :ride:

ups says exhaust is coming tues.

Oh, I know. I'm like a kid watching the "Santa Clause" updates on the news on Christmas Eve.:) :)

Tires weren't in yesterday, but maybe today. Test ride for sure this weekend.

MXkid, I agree some aftermarket exhausts sound nice and may (unlikely) put one on in the future. However, I'll still want the stock exhaust if I ever get ready to sell the bike. I have an SV650 streetbike that I would love to put a new "throatier" exhaust on, but like I said before I'm cheap:excuseme:

oooo the v-twin sport bikes sound so bad ass with an open exhaust

RC51 with exhaust = :eek:

hate to be an ******* but i'd sell that SV before putting money into an exhaust for it lol :crazy:

      Hello all,
      I have a 2005 crf230f im wanting to modify my bike as best as possible for a sumo style bike. My first thought was an engine swap.
      Has anyone done an engine swap on this bike before? If noone has what engine would be the best fit to do so?
      The 230cc engine desnt have enough umph to really be a daily driving unless taking backstreets all the way to work so im trying to see what i can do to make it have the umph.
      Some of the mods ive done include the airbox mod, a lighting kit, sprocket change (i believe i have a 42 and 13 but cant rememebr), and a jetting mod where my dad took the stock jets and drilled it out just significantly enough to make her kick as much as she can.
      Im looking at doing handlebar risers, an airbox mod on the right side of the bike for even more airflow, cr500 shock if possible. 
      I am absolutely in love with the turning radius and nimbleness this bike has. I have ridden my dads BRP and my brothers crf450r and they just cant skirt around the world like my bike can so im trying to get the power (hopefully) of a bigger bike in the body of my bike. 
      Im not looking to have to completely tear the bike down to modify the bike, but if need i can make it happen. Before i am forced to modify the frame to accept another engine, are there any straight swaps that can happen? Are there any other performance mods that can be done to get that speed a little higher without sacrificing too much reliability?

      I have an 03 CRF150F that has a pretty bad wobble in the front wheel.  It has the OEM rim on it, 19x1.40 w/36 spokes.  For some reason, Honda is REALLY proud of their CRF150F rims, and want $125 for a new one.  However, the same size front rim from an XR/CRF100 or CRF125F are only $25-$30.  I realize that the spoke/nipple sizes are different, but is there any reason I couldn't use an XR100 rim and lace it with CRF150F spokes if I drilled the holes out larger?  Could nipple size be an issue?  Center well depth?
      I'm not looking for weight savings, or bling, just a straight wheel assembly.
      Or, if nobody knows the drop-in capability, I sure could use a lesson in spoked wheel compatability.  Does anyone know a good site for learning what features really matter when trying to swap rims?
      Thanks for the insight in advance.

      They will fit with some modification I did it on my bike 2007. The 2015 through 17 has an extra mounting hole on the tank and shroud so I cut the threads off an extra mounting screw and superglued it in that hole giving it a more authentic look. Except I didn’t use enough glue on the right side and the screw fell out. I had to use spacers on the front mount. And drill a new hole on the original tank mount but that doesn’t effect the original shrouds mounting. And a new hole on the new shroud. The new shrouds also sat correctly against the tank not affecting the seats look. Pictured is the two shrouds next to each other and the bike with the original shrouds. Also pictured is the listing for the shrouds and I only  spent $30 AUD on the OEM shrouds which were listed at $35 after my offer was accepted. They came with new hardware. And it was well worth it. I hope this post was worth the time😂.

      SOLVED*** No timing issue, just had trouble lining up TDC  Going to rebuild top end to fix low compression. Thanks for the help TT
      So I bought my 2003 crf230f a few months ago from a friend. The bike has definitely been ridden, and was blowing a little bit of smoke when I bought it so I knew the rings would be toast sooner or later. After a basic tune-up the bike ran really strong and I continued to ride it a few times a week for a couple months with no problems... Until last week when I was riding and it died on me. At the moment when the bike died, I was coasting down a hill so there was no extra stress on the engine, I just noticed the engine shut off- almost like running out of gas.
      From that moment on, the bike would not start so I towed it home and checked the essentials... Air, Fuel, Spark, Compression.
      Air- The new air filter I installed when I bought the bike was already covered in dust, so its possible the piston rings got even more dusted. I cleaned and oiled the filter anyway (the bike wouldn't start with the filter removed).
      Fuel- I recently changed my jetting to Mike Coe specs, and installed a larger pilot jet to eliminate popping on deceleration. The bike ran great with the new jetting and I know the carb is clean. I went ahead and cleaned out the gas tank and fuel lines and cleaned out the carb yet again.
      Spark- Spark plug was white due to running lean before I changed the jetting. Plug turned more of a brown color after jetting, indicating better A/F ratio. Replaced spark plug anyway and can see strong blue spark. Also, gas is making it to the plug.
      Finally did a compression test and had low compression. I adjusted the valves which were a bit out of spec, and saw no improvement. A wet compression test (one tsp oil in plug hole) showed higher compression, but still low, indicating the piston rings are toast. I ordered new rings and top end gaskets and will rebuild the top end next week.
      I was also wondering if I have a timing issue, since the engine at TDC (pic 1) shows the cam sprocket about 30 degrees (in the retarded position?) off from being horizontal with the head, as it should be according to the FSM and Clymer manuals. Also, when cranking the engine CCW by hand, the flywheel tends to spin past TDC and happens to align the cam sprocket perfectly horizontal with the head. Is my timing way off? Also, the flywheel has a || mark (pic 2) near TDC that I used to adjust the valves. Just today when I took the pictures, I noticed a |F mark (pic 4) that usually spins past quickly so I never saw it before. both marks appear close to TDC but the engine always wants to spin to the natural position (pic 5). Where is my true TDC? Manuals only show a |T mark. Are the cam sprocket lines supposed to be horizontal with the head? Maybe it jumped a tooth? I have read the cam chain tensioners are known to fail also.
      Edit: Found the T mark, updated photo near bottom of thread
      tl;dr
      Bike died on me, has low compression, going to rebuild top end. See pictures. Could this be a timing issue also? Does anyone know if the lines on the camshaft sprocket are supposed to line up with the horizontal lines on the head? Thanks in advance for the help!

      Pic 5- Engine wants to spin to this position: Cam sprocket lines horizontal with head- https://imgur.com/S3rPRgd
       
      Let me know what you guys think. Has my timing jumped? I appreciate your help!
      Cheers,
      Spencer
       
      Edit: Finally found the damn "T" mark. Always spins past so I wasn't able to see it before. Updated picture posted near bottom of thread. Timing looks fine so  just going to rebuild top end next week to restore compression
