Pics are from last weeks smoke out ha ha.... started hearing a tick, took it to a local shop ...got the valves tightened and cam chain tightened...started smoking a few days later... in the process of getting the top end cleaned up ... lots of carbon and shain tensioner finger chewed up small burrs in the cylinder sleeve and a little excessive play in the piston arm so were planning to pull the crank case appart just to see what else all i know is i miss ridding this beast... had that airbox reoved and the new turbine 2 installed was gonna get the sprocket but all that happened....

hello friend! you have checked the seals of the valves of the cylinder head?

The mechanic did mention something about i ll ask him again when there open thanks!!!

The service manual has a different cam chain tension device then what is actually on my bike?

Here is what is in the service manual book but the parts book has a different type.
It has device that has an adjustment screw on top.



Then it has these instruction for manually adjusting it…the type above


That part was replaced with this part and I am pretty sure it is supposed to be automatic and not adjustable? This is from a DR200 parts book and identical to what is on my bike.


It looks like it has notches and would moves as the slack increased in the chain? The spring would have constant tension on it and then it reacts to pressure from the chain? The spring locked out until the chain push past a notch then it springs the guide forward to the next notch?

Point is the device can only be removed and cleaned, if you hear what sounds like a cam chain noise then the device is removed and inspected, what notch is it on? No more notches left the chain needs to be replaced?

I am only guessing since the manual I have is outdated, so I have to guess? I paid not to and still have too…Thanks Quality Blink.

I had a similar Issue after dismantling my bike , and fitting -wrongly- its Piston 180º degrees turned, Please LOOK at that Piston : Intake valve is Bigger, therefore it has a Bigger POCKET!!.
In contrast : Yours has the Bigger Pocket pointing to the the exhaust!!. What puzzles me : IS that arrow wrong??(allways follows flow=Exhaust, apparently its ok.. . BUT.. .)
A worn piston seals oil properly ONLY with its Matching Own worn cylinder, and ONLY in its correct position.
- My Guess : STUCK Rings will make your piston Louder!!, Check carefully that : Piston rings move freely along their groove, check that they cant stick/SEIZED at some point because of carbon build up or Heat seized. If SO :
0/drown the piston into Nitro painting solvent a whole day.
1/Remove the rings.
2/Remove the Carbon with a broken piece of ring.
3/Use a folded 150 or + Sand paper to soften the grooves bottom from scratches.
- USE allways a quality Sintetic oil, cheap mineral oils Burn Building Up Hills of Carbon!!.

It sounds weird to me that you are removing the crank, as its bulletproof!!, you can only break it after running dry/OIL-LESS. and you´ll seize your piston first.(maybe your has : cant see its front/exhaust skirt in your pics.. .)
I´ll check its Bigend/Smallend gap/play first!, needless to say you need to remove its pistonPIN to do that.
check the wear of your PistoPin, I´ve often seen a loosen Rod/off-limits that had that gap because of a Worn Pin !!!
Check your oil PUMP/Filter before starting the bike : it may be clogged by debris, make sure it sends oil to the head, CAM is very noisy unless under pressure.

yeah the picture i took were from the first shop that basically dismantled my bike and were about to replace and resurface things that didn't need it after 1 month of nothing happening JP motor sports of Chula vista, California, got the bike in 3 boxes
about 3 weeks ago after they ordered basically gaskets and a cam chain tensioner arm, and had on hand a valve sleeve, oil and reassembly along with the larger sprockets grand total $954.00 considering i bought it with 74 miles on it at $1800.00 added that fmf pipe and k&n air filter and misc oil filters and breather filters im at 3000 thats the price out the door for a brand new xf 200 without the mods so im ok for now..... ill post pics in a couple of days thanks for all the help!!!

2 months no ridding then tonight the opportunity to get my bike ride it 50 miles in the cold, dark, wind. screaming and hooting the whole way back commitment to ride.
