Xr200r Cam Chain way to loose

Recommended Posts

Hello I just recently got a brand new timing chain for my bike off XRSONLY.com I gave them a call and yet to hear back from them so im jumping on here to ask questions.. there is a cam tensioner that slides up and down with the engine running but i couldnt seem to get the chain to tighten up for me. so i took off the pulse generator and at the lower end the flywheel.. what i seen didnt look to good to me.. the chain is to the point that its so loose that i can jump a tooth with just my finger.. the shaft for the cam tensioner slides up and down to adjust how much it pushes on the chain.. i started to try to do it by hand to make sure it was adjusting right but i dont even think its frees up the slack enough to make it safe.. when you push the cam tensioner up to the top and makes the tensioner push into the chain (tighten) then when you pull it down and takes away from it (loosen). Is there something im missing or?
 
I have the bolt in at the top of the cam tensioner before someone asks since its not in the picture. I counted the links on the chain its 100 which i believe what it calls for, i mean the chain looks like it can have a 1/2 link to a link out to make it work right i had a old chain from a 125 which is two links short and it almost fits.. does anyone have any ideas for me.. :banghead:camchainaspx_zpsfa547383.jpeg
 
As you can see in the picture the chain is slapping the middle of that piece of engine.. i was almost thinking about taking up the slack by shoving something up between the cam tensioner and the wall to help bow it out in the middle to apply more pressure on to the chain..
 
I also wanted to add inside the yellow that got hit by a peice of engine that broke off and got bent i fix it back to where it looks like it needs to be would that have anything to do with the cam tensioner?

"I have the bolt in at the top of the cam tensioner before someone asks since its not in the picture."

I did list that in the info but yes it was..

 

i figured it out the tensioner piece at the lower were it slides up and down it was ( you can kinda see it in the picture ) bent to a L shape what is need to look like is about a 45 angle on like in this picture.. i pulled it out and bent it back down and bowed the middle out more and it looks brand new!honda-xr200-1980-usa-cam-chaintensioner_

Buy a new tensioner set. Also new chain should be much tighter than that????? Your sprockets worn out from before????

Something is amiss here. The part you highlighted doesn't do anything as far as tensioning. You can see that the spring loaded arm is fully extended and is not even making contact with the tensioner. You can also see that the tensioner is in almost it's highest position. Worn guides can't account for that much slack. So either you have the wrong chain or the tensioner is bent or it isn't attached properly at the top.

Chadzu is correct. I believe you have a 125 tensioner (1/4" shorter to start with) and no way a new chain would be close to that loose. Sure you dont have a 125 cylinder on that as exactly 1/4 shorter and those models 125's use a BS25-98 chain where as 185/200's use a BS25-100 link chain. Plus like I said before your tensioner looks bent.

 

A new chain with good sprockets should have virtually no slack and tensioner would be close to bottomed out.

In the post by "spooledupgti" on June 21, 2014- 04:53 PM he shows an exploded view of the cam chain/tensioner. I've rebuilt my 2002 XR200R many times and am in the middle of another rebuild. I've ordered the following parts: items # 2, 3 and 8 as well as a head gasket. The main problem here is that the chain elongates with use. By the way, there's a good write up on page 7-15 in the 2000-2002 Honda Service Manual on this section. Rock_Hound, Sept. 12, 2014

You can put a little bolt down in the middle of it and pull up and that will tieten it up

Easy to get the wrong chain, and easy to check.  I suggest checking the box it came in, somewhere it should have a number that indicates the number of links. A XR185/200 uses a 100 link chain, CRF230 use a longer chain, and as previously reported the 125s use a shorter chain. 

The whole mechanism pushes up on #3 and causes it to bow against the slack side of the chain. #8 guides the tension side of the chain.

If you look at the pictures the OP put up in the first post you can clearly see that putting a little bolt down in the middle of it will in no way tighten it up.

Here is a picture of the cam chain tension stuff on my XR200 mule engine, all used parts. Notice how far down the end of the chain guide extends.

      A while back I picked up a '95 XR250R swingarm that I plan on installing on my '90 XR200R in the near future, to save a little weight and have rear disk brakes. 
      I missed out on a totally complete rear brake system for $75 a while back which sucks. I look on Ebay every now and then hoping to find a great deal on a complete or near complete setup but no luck lately.
      Is anyone aware if Honda used the same brake system that was used on the '90-'95 XR250R, on any other bikes? 
      If so, then I can expand my search. If not, then I'll just keep looking at 250 parts til I find the right setup for the right price.

      Hi all!

       I've got an issue, one of many when it comes to bikes. I searched throughout all the pages I could find pertaining to my situation and couldn't find very much useful information.
      So the issue is, the bike has no electric start.... until it's hot enough to melt steel that is. It will bump start first time every time. But I can sit and crank the starter over for ever and it'll never start until the charger is bumped up past 200 amps. Not good.

       The story so far,
      Got the bike for 1k cash. Guy said it has no spark and no second gear. This particular guy also only ever rode newer crotch rockets. Brought it home pulled the choke, attached battery charger and she fired right up. Ran like absolute crap, but oh well I figure it's an older bike with only 10k miles so it probably needs a good carb cleaning. Took the carb apart and didn't know I messed something up until way later(didn't tighten down main jet). Oh well she runs well enough if I can get her started. Moved from California to Oklahoma. Eventually found the money to fix 2nd gear, and as I am a certified Honda small engine technician apprentice I figured it would be no big deal. Completely tore down engine to it's roots replaced 2nd, and 5th gear(because 5th gear connects to 2nd on the countershaft) dogs were worn pretty badly on both. The engine looked quite good compared to most others I've seen. Put the engine back together as per the service manual. Did all the right steps including loosening the banjo bolts to test for proper oil pressure. I even tore apart the electric starter to clean the contacts and the brushes and replace the dielectric grease. Adjusted the valves as per the service manual, replaced all gaskets, o-rings, seals, and oil filter.
       Finally after about a month of waiting on parts and reassembly I get to start her, only she doesn't. Electric start is still giving me the same issues I've always had. So I replaced the Ignition coil, CDI box, and put a new battery in, plus the starter motor rebuild. Nothing. Still cranks forever. I said what the heck and tried to push it slightly down hill and bump start it, and voila... fired right up! Once she gets hot enough and the stator charges the battery enough it'll electric start... sometimes.
       So I looked towards ignition, used a tool called ignition mate. Pretty awesome tool if you can afford it. Well while cranking the ignition mate reads the spark plug is getting 1-4kw of "spark" every cycle, well it only fires after getting up past 5kw sometimes 6-8kw. And sometimes the ignition would be intermittent as in it wouldn't give any spark at all. I cycle the ignition and it seems to soft reset the bike as it will usually give it back spark. I tested this with the new and old CDI box, the old one would never spark. Ever. So I threw it in the trash. A month later I stil l can't figure it out.
       Is there something I'm missing?

      TL;DR
      Bike won't start using electric start only bump start before and after engine rebuild
      Electric start works after pushing the starter past about 200 cold cranking amps or when hot.

      30 years ago I sold my beloved 1985 CR500. I was young and needed money for a car. I had a lot of fun on that bike and some of the best dirt bike memories were made on it. Out of all the bikes I've owned it's the only one I regret selling. I've had opportunities to buy a 85 cr500 before but never pulled the trigger figuring leave the fond memories in the past. Well today I couldn't pass up the bike any longer. I found me a nice project bike to take up some free winter time. The bike is all there and it runs but most importantly it was cheap. Not the prettiest but it's mine. With lots of money and time it shall be returned to it's former glory and be ready to make some new memories.
