hey all,

ok my bike is haveing this lil problem. its a 92 tomos targa w/ a bore kit on it. ok when im accelerating on the bike first gear goes by with no problem but then if im on a hill after first gear it hits second then i will give it more gas to get up the hill and it starts to ping violently. if i give it a lil less gas it stops. or if i pull the choke it almost stops but after 20 miles an hour it stops all together. now if i accelerate with quater throttle it doesnt do it at all but at low speeds if i slam the gas it pings. i tried the timing plate in the advance position the retarded position and the normal and everywhere in bettween. this bike has a point and condensor ignition. oh and this problem only happens when the bike is fully warm. i run it with premium gasoline and 100% synthetic oil at a 4 oz per gallon ratio.please help...i dont want any harm coming to this 800 dollar bike!

Re: pinging!

that sounds like a timing problem mike, but you said you checked that already,

did you check for the correct points gap before you checked timing?

Check the timing and make sure it is within spec.


Re: pinging!

the pinging might be your reedvalve, you might have a bad fuel to air ratio

Re: pinging!

Mike,I'd try a plug chop to make sure you're jetted right,and also make sure your exhaust is not restricted.Also,you could try a colder plug.
