cam journal repair takegawa

is there any way to repair cam journals . its a takegawa super head. hope its not a paper weight :-( thanks for any info.

Only logically option I can think of.

Is Purchase a Stage 3 roller cam (the monster cam), and roller cam Holder from Takegawa, and have the head machined, for the roller bearings.

Might want'a inspect/replace the valves and guides too.

Oil pump and oil passage ways, as well.

Megacycle use to offer roller bearing cams conversions with head machining, It wasn't cheap, from what I recall!

Keep me in mind if you deside to let it go.

You won't find anybody to machine the head like it is in stock configuration, roller bearing or not. The only option is like gmann mentioned, you need to cut thru the valve cover mating surface on the head for tool shank clearance like megacycle did. Stock heads are probably cast with finished cam bores.

I would think a new head would be cheaper.

check with they fixed the cam journals on my YZ400 for $100 by welding and remachining them. Might be worth giving them a try.

How'd it happen? Run it outta oil? I'll second what GMAN said.

was running it a bit hard . and i think the oil pump took a crap happened real fast . the motor had fresh oil and was filled right :busted:

this "was" your old kit actually bikes n wheelers .

yzman 400 thanks for the link ill check it out.

its a shame that this head is possibly junk because of this would be nice if at least the high priced takegawa heads had some kind of replaceable cam journals but i guess this dosent happen too often :thumbsup::banana:

ill post some pictures of the damage in a little while for those interested




notice all the metal under the cam area :busted::thumbsup::banana:

Wow! When my oil passage was clogged (long story) it made a high pitched whiney sound, which saved it because I shut it off before any damage was done to the head. Did yours make any wierd sound at all?

between my loud yoshi pipe and helmet. it was too late by the time I herd the racket . suprisingly it never really lost anypower . when I slowed down herd the knocking and it was RIP time for my

you play u pay I guess

sent the head out to engine dynamics . see what happens . might or might not be

i predict paper weight.

I think you will be suprised at what they can do. I thought the same thing about my 400 head and they didn't even bat an eye at it.

i hope so :busted::thumbsup::banana:

keep u posted on the report back.

If they want to charge too much you can always get another Takegawa kit and sell the cam and cylinder separately on ebay. I sell the cylinder and piston as item and sell the cam on another. I got over $200 for a used BBR TTR 150 kit. So if you can get near $300 for both (might be wishful thing) that would be like paying only $300 or so for a new head. Just a thought if you going to spend close to $200 for head work, valve guides and whatnot. But if they can do it for like $100 or so, that would be the ticket or go with a bearing cam and make it better than new.

good info. socalxr. I won't be spending too much to repair this head. even if its fixed will most likely be a spare. I'm leaning towards saving for hole new kit anyway I got this kit used so its not such of a slam in the pocket for me ... the compression was always a bit below spec on this kit

by the time I get another cam . cylinder ect ect best bet is a new stage 2 kit .

the head is can't be fixed.

keep a look on ebay. parting the entire bike out. bbr gold triple. yoshi pipe. engines only tm24 carb . baja designs light and stator . plastics . takegawa 115 cylinder. stunt pegs . ect ect


Powroll sells a cam with a roller bearing whose OD fits the factory journals, good or bad.

Also there was a thread on here about a kit to install ball or roller bearing on the sprocket end of the cam. Bothe of these could be a bolt in fix.

So before you spend a load of money call Powroll.

      Anyways so I got a 1985 xr200r RFVC, and I have heard that the oil really overheats and in some cases people have had their bike (Rarely) go up in flames, however I don't want to take any chances and I heard that there is a way to put on some sort of oil cooler... How do I do it??

      I have a '01 XR200 and i was wondering it anyone could give me a top speed for it. Where i live its more 2 lane highways and things so i cant find a good straight to run it with a car in. Thanks

      I decided to compile a list of common modifications for the XR200 in hopes of eliminating some of the common questions asked on this forum. These modifications are intended to improve the overall performance of the bike, without sacrificing reliability. Feel free to suggest amendments or things to edit.
      The XR200 is an excellent offroad machine; however, it was for the most part obsolete about 20 years ago. The bike can still be accredited to having probably the best reliability of any full size bike out there. When properly setup and modified, the "little XR" can run with the modern big bikes, especially in the tight and nasty technical terrain.
      INTAKE: Remove the airbox snorkel on top of the airbox. It just takes a little prying and it's out. For $20-$40, you can get an aftermarket filter (UNI, TwinAir, No Toil), that will help increase airflow. Rejet one size up on the main and pilot.
      Here are the stock jetting specs to give you a basline:
      Stock jetting
      XR200 (not XR200R)
      main 102
      pilot 35
      Needle position 3rd groove
      Pilot screw initial setting 1 3/4 turns out
      XR200R (81-83 only)
      Main 138
      Pilot none
      Needle position 3rd grove
      Pilot screw initial setting 2 1/2 turns out
      XR200R (86 and later)
      Main 112 (86) 110 (87 and later)
      pilot 38 35(98 and later CA only)
      Needle position 3rd groove
      Pilot screw initial setting 1 1/8 turns out
      When these things are done, the bike will breath much better. This is the single greatest modification for a bike ridden at high altitude.
      Overall cost w/out filter: about $10 for jets; $20-$40 for the aftermarket filter
      ENGINE: The greatest improvement to the XR200R engine is a big bore kit. Here are the 2 most common kits:
      Other options include porting and polishing the head, high compression pistons, hotter cams, etc. The more you do, the more reliability is reduced, but it is a trade off for power. Another option is an ’83 -’85 ATC200X cylinder head. It has a .5mm smaller bore, so it would need to be bored to 65.5mm, however, it has much larger cooling fins. For motors that are constantly being run in extreme temperatures, this is an option to consider.
      Overall cost: Varies by modification, expect to drop $200-$1000
      EXHAUST: There are several aftermarket exhausts on the market. These range from silencers to full systems. Prices range from $80-$500. Most aftermarket exhausts will give about the same improvement. The engine will rev quicker, which can be nice, but mostly they all just make the bike louder. For mild improvement to the stock system: grind the weld off of the inside of the header and remove the small cap held on by 2 8mm bolts at the exhaust tip.
      Overall cost: 0-$500
      SUSPENSION: This is a major weakness with '92-'02 XR200s. The first option for the forks is to give the springs more preload by adding a larger spacer on top of the springs. The second, most common option is to swap out the entire suspension. '84-'91 XR200 forks and rear shocks will bolt right up, and ‘81-’83 XR200R forks will with the corresponding triple clamps. '84-'89 CR125/250 front ends will bolt up to any XR200R with the addition of a spacer. This particular swap is more complicated, but also adds a disc brake and improves the bike tremendously when used in combination with an '84-'91 XR200 rear shock. See this thread for more info on CR front ends: These parts frequently show up on Ebay and can be obtained very cheap. Also, a visit to or similar suspension tuning company couldn't hurt with any setup. Emulators and progressive springs will get conventional forks nice and plush. Currently, XR250 rear shocks are in question as to what years will work; therefore, I do not recommend them at this point. Many people have them on their 200, however there is not a definitive answer for the years yet. Be sure to research before you buy.
      Overall cost: Generally less than $100; for Racetech tuning, expect to drop $200+.
      WHEELS: An 18" rear wheel from an '86-'89 XR250 will bolt right up. This can help because the 17" wheel spins too much sometimes, and tends to work its own spokes loose. There is also a much greater tire selection with the 18" rear wheel.
      Overall cost: Generally less than $100
      LIGHTING/DUAL SPORT: Lights can easily be added to the 200 by tying into a pink wire that just comes up under the tank, then loops right back down to the stator. This wire has no purpose, and was left behind in the wiring harness, because the non-American XR200s had lights, and Honda didn't pay to change the wiring harness or the stator. I have personally tested it up to 75 watts, but I wouldn't recommend going much higher. From there it is simply a matter of wiring it the way you want it. In any application you will need a 12v voltage regulator. I would be happy to assist with any questions on the wiring you may have, since I have redone mine several times to change things. Also, please visit this thread for some diagrams (about halfway down the page): Each wiring job is different, so it is difficult to write a generalized way to do it. For dual sporting, there are kits from Baja Designs and similar companies, or you can be creative and pull parts together yourself, and in result save lots of money. The first time I had lights on my bike, it only cost me $6. A speedometer cable can be attached to the speedometer port on the front brake hub, as long as you can find a way to mount the speedometer. TrailTech computers are the easy alternative to the manual speedometer.
      Overall cost: Dependent upon creativity. Baja Designs kit runs around $450
      Helpful XR200 Links: (engine info) (adding lights)
      **I need more links for XR200 INFORMATION, NOT PRODUCT websites....Post them in this thread if you have them***
      Again, please feel free to suggest editing....I'm sure there are MANY things I forgot. This is just a baseline to get started.

      I don't have photo access yet but lets see your 200's.
      My dad is planing on selling his 02 XR 200, but it's in need of a rear shock. I was told that these shocks arn't servicable, so we priced a new one out. The dealers asking over $400 for a new one. So my question is, what other bikes have a rear shock that will work on his 200? Thanks.
