I am new to the atv repair game as a found a solid project on CL. I picked up 2001 foreman 450s for 650$ said that it had sat along time had carb issues wasn’t hundred percent sure all that was wrong with said got off an old rich farmer who checked his cows with it started acting up parked went and bought a brand new one. Must be nice he it wouldn’t run right took it to a guy to fix it never happened so he just wanted his money back on it. So at 650 I was willing to take a chance. I’m hoping you guys can give me some good advice and it will be much appreciated. I am handy with a wrench but by no means a mechanic. Look forward to being apart of this group everything I have read so far has been great. I bought some land and need a work /utility quad to help my back out alot of brush downed trees. I am in the process of going thru it right now have some questions you guys I’m hoping can shed some light on. Thanks for having me
I’m going to cover everything I’ve done. Clean out out tank with gas. Replaced filter and fuel lines. Had to order new seal dust cover connecting boot and air duct for air box all was missing when I got it. Changed oil and filter. Took the carb apart once thought I cleaned it good wasn’t the case was running way way lean was 2.5 turns out like manual said but was idling way high. And was getting hot quick so did some reading went back in clean carb extensively.
Decided to get a k&n so ordered a sigma 6 jet kit put in the 132.5 main and moved the snap ring down notch like it said to do set it at 2.25 like it said to put it back together and is running what seems to me really good.
Alot of power starts immediately not poppin so then I notice smoking from the leak from valve cover ordered gasket but not sure on torque spec the manual says 6mm flange bolt but it’s a 10 mm head which isn’t listed in the manual gonna tackle that today I hope sorry to ramble but that’s the summary

Things that I have noticed that needs fixed 1. vacuum lines they look like dry rotted and cracked from hydraulic brakes
2. Valve cover leak there was alot of build up around that area I scraped off with putty knife.
3. Front right cv joint wrapped wire around it destroyed boot.
4.the fuel pitcock Wil not stop the gas when turn gas off
I’m gonna post some pics any input would be appreciated thanks guys
