[larry251978]

i just bought a 97 350 warrior guy told me he had it in pieces like every thing even motor was tore arpart before i bought he had it all back together got it home put battery, new oild in it and started it up made a weird clacking sound sounded like timing chain was lose checked it, it was good and tight looked at started gears theye looked good coul;d use some advice cause not sure if i should pull heads off make sure pistions not on backwards had the once before and it broke the rocker arm

clacking maybe valves, i would check them first if you think noise is coming from top end ....

[larry251978]

i will check that out sounds like its on left side but not sure

[oxidized_black]

i might have the valve specs, i'll check it out for you ...

[larry251978]

ok thanks lol i cant find my book

[GREENIE]

is it a really loud noise or just a ticking sound

[larry251978]

it a loud clunching noise sounds like coming from bottom end is it possalbe ta have the balance not positioned right and it might hit the connecting rod a bit

[GREENIE]

i m not sure. if it was just a ticking noise i d say it was your valves. but i don t know what that would be. does it do it all the time.

[larry251978]

yea makes nosise all the time i checked valves there in spect so i not sure either gues ill take motor apart and see what that guy did thx all for the help

[GREENIE]

your welcome. sorry i couldn t help much. i don t know very much about engines.

[larry251978]

ok np yea i have built alot of these motoras and the guy that put it together dont think he knew what he was doing ill post let ya know what i find pout

[GREENIE]

i just sold a 2001 warrior because it kept cutting out . i had it rebuilt and then it just started running funny . i had it to just about every shop around here but they couldnt figure it out. sold it last month for $500 just put brand new plastic on it a couple years ago. the guy took it to his friends and figured out there was a wire hooked up backwards. i ve kicked myself in the butt ever since .

oh man that sucks !!!

[GREENIE]

ya got tired of trying to figure out what was wrong with it. so the opportunity came up so i got rid of it. sucks i sunk a lot of money into it but what the hell its making someone else happy so i guess thats a plus

[oxidized_black]

well yes, that's good. i know it gets to a point of how much more money do i put into something to make it right, and then of course the next 20 would have fixed it ... but that's always the way it seems to go ...

[larry251978]

[GREENIE]
