200x pinging sound???

[tyman]

I've noticed that if my threewheeler (86 honda 200x) has a ting sound if you stand beside or infront of it while its running... but when you get past about 1/3 throttle, you can't hear it.... any ideas???? it does have a performance cam but i don't know about anything else.. just bought it....


and is their any way to see what kind-o-piston is in it without pullin the top end off... ????

thanks

might need better fuel, is it metel on metal??
did you put the cam in?
rockers need adjusted?- the coil springs arent binding up are they?,drop in cam or race? how does it run
have someone hold a cloth over the exhaust and you can here it better

might need valves adjusted

I would say either valve adjustment or cam chain loose. As for the piston any good shop should have a tool to look in the cylinder threw the plug hole. (I cant remeber what the tool is called) but they are pretty cool.

It sounds like you need to adjust your valves. My X was doing that a little bit when it was cold. clearance should be .002-.004

alright... i'm gonna assume its the cam chain cause that sounds easy to adjust.. and i can't possibly screw it up :X i hope... well anyone want to tell me or link me to a thread on HOW TO adjust can tension.. i looked in the service manual and it shows the tensioner.. but idn how to adjust it..... can you OVER adjust it??? just a half turn and check to see if the noise went away?

[tyman]

anyone find anything on cam chain adjustment yet???????
