200x head on a 200s PICS

[oscarmayer]

your timing needs to be where the manual stated.
you also need to consider the carb is not tuned. did you rebuild the carb? if not try rebuilding it. sometimes the parts are so worn that even cleaning doesn;t work. the holes can be ovled out and thus cause incorrect fueling (hence why a rebuild kit for a carb is only $14-$20 shipped)

get the timming correct (T to notch and cam to notch) then redo the carb and it should be much better. are you sure the timing chain guide is not worn out? if it is it won't provide proper pressure to the chain and that can also cause issues. another thing is the spark advance is mechanical. it is part of the cdi unit. it's te part that has the magnet that rotates. if those springs are missing, broke, rusted it can keep it from working correctly.


Get the factory manual and READ it READ everythign about the head and timing. then follow every step. you have been jumping all over and doing what ever you want. How can we help if you don't follow simple manual directions that the factory wrote? follow exactly what it tells yo and then come back if there's a problem.

I read the manual.

I didn't replace the timing chain so their is a little slack, making it at the most 3 degrees off.

The carb is the same as before, same as the timing is the same as before. I realize their may be problems with those things, but it is the same problem as before the change.

Their is a new problem now that I need to chase down.


I didn't deserve that "tone" you took with me. I didn't do anything out of spec.


For reference here is the thread I made when I was having trouble with the valve timing

I can't believe that your timing chain has 3 degrees of slop in it. Sounds more like a carb problem to me as well

[litebulblsc]

3 degrees was a guesstimate. I checked and double checked it. I set a level on the surface that the crank timing mark cover threads into and leveled the motor based on it. Lined the mark up dead on. Pounded a screw driver into the wood bench after passing it through the pull start thing to hold it at TDC. Then when I tried lining the dot on the cam it was a little off. Moved it a tooth and it was off the other direction. If you got a better explanation other than a stretched chain, let me so I can check into it

I'm not "giving you a tone".
You stated eariler it was out of timing and not correct per the manual, then you did NOT set it per the manual but back to where it was. how are we supposed to help if your not doing exactly what it says and doing what ever? It's not liek you have years and years of expirnece and know what your doing and have reasons for doing it, your flying by the seat of your pants here and aren't doing what the manual says. any advice offered isn't going to help unless your at least putting it to factory stock specs to start. the chains usually don't stretch much, but the guides and tensioneers do wear so those should have been replaced. did you adjust the timing chain tensioneer per the manual? if not then do that and see what happens (engine must be running to adjust it correctly) are you sure all the connections are correct? double check all of the connections of tghe timing tensioneer. thts requires pulling the side cover off and checking where it conencts. something is wrong so look at every thing and check it all. could the crank shaft chain sprocket be bad? better hope not as those are expensive to replace due to hours needed to do so.

Here are the pics of the 200x stock piston . Nice condition lots of life left and rings are still very tight in the stock 65mm bore . wrist pin very good also .

Haven't seen this post. The one adjustment on the carb was set incorrectly, set it to spec and put a new plug in it and it runs good.

I have one more question for everybody, what exhaust? I need something that flows better then stock 200s, but nothing too loud. Whats every bodies suggestions?

[oscarmayer]

how about a cobra system or bassoni (if you can find a nice one)?

[litebulblsc]

I heard the cobra was kind of loud, but can't beat the price.

And does any one sell bassoni or are they discontinued? I might try looking for a good used one.

[leevarnado]

i've got a bassani for sale.

[litebulblsc]

I don't have money for one right now

Yeah, I finally was able to get a gasket set so I can build up my motor.

Also suppose to be rebuilding someone elses 200 in trade for a cobra exhaust system.
