i'll try to make a long story short. by the way i know jack *%! about engines. my 84 225 dx was knocking bad when i gave it a little gas. a friend of mine, who knows engines, said it was the rod and he'd take it apart. he brought the engine to a local shop. that guy took apart the crank. the bearings looked good but he said the wrist(sp?) pin was severly worn. he replaced it as well as the bearings and rod while he had it apart. it was put it back together and it sounds good until i put it in gear and lightly give it gas. the same knocking sound (loud!) appeared just as bad! it goes away quickly after the revs go up. it only does it when in gear and i first give it some gas. after that it goes away and sounds fine through the rest of the gears. can something else be causing this knocking sound(not a rattle,ping or tapping sound) in this situation? sounds like it's coming from the bottom. could the new wrist pin be wrecked already? please guys, i need your help. i'm already out $350.00 on this. thanks in advance.

Take off the right cover of the engine, and look at the clutch basket. Make sure no screws have come loose and are clanking around on anything, this happened to me and instead of checking that first, I tore the whole engine apart and I shouldn't have....:(

redman,when you say it only does it in gear,and stops once you are going faster...does it knock all the way through first fear and stop when you shift to second? if you can rev the engine up in neutral..and dont hear a lmocking sound..then it has nothing to do with your rod/wristpin. it could have a tooth or two missing off your first gear inside your transmission.

ssj3goku......i checked the clutch basket already...seems ok.cmracer15......i let it run for awhile. it's knocking now when idling but goes away when the revs go up. it just sounds worse when i put it in gear and initially give it gas. it will knock initially in any gear when the revs are low. it then goes away and sounds normal(quiet) when i give it more gas. the best way i can describe it is that it actually sounds like someones in there tapping a hammer. what the @#%! is going on. please somebody help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

If its a 4-stroke then it may be valves. Or the gas might be bad. Low octane or something.

Sounds like your not getting oil possibly. I would make sure it's getting good oil pressure.

[REDMAN225]

thanks for your replys so far guys...i still cant figure it out. dumb question... anyone know what would cause low oil pressure?

[bbechtel16]

Faulty oil pump? Or leak in the oil line? I don't know what I'm talking about but that's the only think I can come up with.
