March 25, 200620 yr Howdy all;Don't know if this is the right place to post but,My Bro bought a 99 Dougie last summer,I'll disrcibe the error best I can, when it warms up it sounds like someone shaking a coffee can half full of ball berrings!Last week he tore it down and said the piston seems a tad loose,brought it and the rest to our local machine shop (their very very good)They mic'd everything and said;It's all good and in spec,can't find the cause of the rattle,I advised my Bro to order up some new rings,pin,berring,clips,He called me last night sayin he pulled the water pump and can rotate the impellar quite a bit before the shaft turns,,,????dosn't sound right to me,so he orderd up a new one. Any other ideas to what can cause the noise???????
March 28, 200620 yr my techno does the same thing on deceleration right? its probably the octane of fuel he is using that is what makes mine do that. just my 2 bits.
March 28, 200620 yr Author ^^^^^^That's what I thought at first,but he runs at least 93 in it,and No,,,It's noisy "all" the time,He ordered up some new rings and pin&berrings.Hopfully that will shut her up. Thanks
April 1, 200620 yr Hi, I just had the same problem you have on your bike. The difference is that I installed a brand new 70cc. kit to my boys Gas Gas TXT 50 and when I turned it on the noise on the cylinder was identical to what you describe: A can half full of nuts and bolts going up and down ! I called Jim Snell from Rising Sun imports and through the phone he heard the motor running. Imediately he told me to take it off and to send it back and that he would refund me the money. He tod me that something in there was not fitting properly and he decided not to start wild guessing which part was causing it. In your case I would guess it might be the cage that goes in the top of the rod, and the pin might be a little loose in there. Hope you fix your problem
