yea id rather do it myself if the tools needed dont cost an arm and a leg. dont have much of a shop but id love to learn how to rebuild the crankshaft rather then pay someone else to do it. what tools would be required?

Any tips on how to press apart the crankshaft and put it back together properly? And thanks so I hear you saying the crankshaft is good, the rod is bad right? The crankshaft did have some heat discoloration on it as well not sure if that makes a difference.

That’s good news to hear. So I think it was the wrist pin that seized. Not sure if that could have broken the piston but I can’t hammer it out to get the piston off the rod and the rod has heat discoloration on it. Maybe maybe not but either way I should replace the rod and crankshaft correct? And I noticed the oil pump felt worn out and there was no oil in the oil cooler when I unhooked it from the motor.

So this’ll be long I’ll give all the background first to see my issue skip to the *** Hey I picked up a pit bike and a foreman for 800 the pit bike was running but the foreman was locked up. Sold the pit bike but when I took the top end off the piston I only found half a piston left. So knowing the rest of the piston was down in the crankcase I knew it had to be pulled and gone thru completely. to pull the motor I went ahead and pulled the rear end off and unbolted the front diff to pull the drive shafts and pull the motor. Now I have the motor torn down completely and have all the parts of the piston removed. I know the rod and crankshaft is shot (heat discoloration and too much up and down play rod to crankshaft). ***so I’m wondering while I have the motor apart what should I check for? I know this motor died from heat as the oil in the head smelled like popcorn. So what should I check to make sure I fix the issue (overheating I assume) and not just the symptoms (blown up motor lol). so put simply I don’t want to just rebuild the motor to have it overheat and repeat the process after 5mins of running Here’s some pics

Ticking can also be from unadjusted valves or worn rocker arms sorry I know this is an old thread just thought I’d throw that in there if anyone (like me was looking for tips on rebuilding a foreman 400 motor)

gotcha yea i was afraid of that tho i have heard that some nicer batteries will come back from the dead so i wanted to give it a shot and maybe save some $$$ (these are like the big diesel batteries two are for a tractor the other is for a bulldozer. not sure what new batteries will run but im sure it wont be cheap. do yall think the viking charger listed preveously will handle a bigger battery for a diesel motor with high cca or should i get something beafier? and yes i agree with @davefrombcthat once batteries drain and sit drained for a while they go to crap but i still wnated to give them a shot and if not that at least have something to use later on for big or small batteries

also wanted to say if it leaks acid from your battery make sure to clean any that might have gotten on your atv. acid will take the finish off plastic, can melt/burn paint off of metal and then cause the metal to rust really bad. i have a 4runner i bought that had an old battery explode under the hood that the owner didnt bother to clean the acid off and now the front passenger suspension is super rusty on the otherwise rust free frame. had a question about trickle chargers. so i found that i could hook up a good battery to a drained one and "trick" the trickle charger into charging both when it otherwise wouldnt have charged the drained battery. now i have three batteries off some farm equipment that have sat for a while and drained and hooking up a good battery isnt enough to trick the trickle charger into charging them. what battery charger (not maintaner like what you get for $10 online of $5 at harbor freight) would yall recommend?

i had something similar to this.. had a craigslist ad up a year or so ago and a guy txts me asking me to give him a verification code to make sure i was real and i get a g-xxxxxx code txt that you get when you forget your google account password and have to enter a code they txt to your phone to make sure its you. so basically if i had given him the code then i would have been locked out of my google account and he would have access to my card number and passwords to pretty much everything. i actually messed with him and gave him a wrong 6 digit code several times and said i messed it up when he said they were wrong and had him send it again and again.. just cause i like to waste as much of their time as possible since i lost 3500 to them.. maybe piss them off enough theyll at least leave me alone

what does the front casing cover on these bikes? maybe something screwed itself in there and the cracked case was just a symptom? yea obviously theres some valve ticking or something going on in the top end but cases dont just crack themselves.. either something hit against it from the inside or from the outside. maybe if it was from the inside then thats affecting the top end and maybe its a different issue all together.

i would check the spark plug like@Ajmboy said. thatll tell you if the motor is running rich or lean. white is lean black is rich (or burning oil) corndog is what you want.

hahahaha fax that trumps to much of a clown to be hitler lol and you say that trumps 'rise to power' is much the same as hitler... i say so what the way someone comes to'power' doesnt describe how they will use that power. also trump never had 'power' over anyone.. the media still held the same power they have today over the general public as they obviously do over you. the fact that trump is taking power from the media in the last 4 years and gives it back to the american people is what pisses them off most. if anything hitler was more like Obama in how he spoke and such

how did this country almost fall into fascism? and if you say it was headed that way, what would you say saved it? the democratic-supported terrorist orginazation called BLM's roiters and looters, or the mainstream media blowing up a noval flu bug and shutting down the nation? (i would say antifa instead of BLM cause antifa is only using BLM as a mask to comit crimes under pretense of bring equality, however Hidin Biden says antifa doesnt exist so i cant mention them can i..) also i dont know what you mean about the military brainwashing folks.. no one from the military has ever told me anything about how to live or what to think. ...but at the same time listening to the things my friends tell me about the public school system, that sounds much more like fascism to me....and guess who created the public school idea originally? and i wont even mention the media.. all you have to do is serve the web and its all one sided and its hard to find just news anymore..its all liberals' speculation hogwash

this makes perfect sense when the mainstream media is all one sided and attacks trump any chance they get.. if you were anti-trump and the election goes against him, why would you look for proof that the election was rigged the democtats using HAMMER like they did in 2012 (if you dont know what that is look it up)

thats a testron/arctic cat product. arctic cat lost its popularity when it started using the kawasaki 650 v twin motor which tend to jump time. other then that id say the old arctic cat atvs are great machines as well as the new textron off-road models. yes they arnt well known, but from what ive gathered they are right there with the new yamahas and suzukis and even close to polaris in performance and quality. my personal experience is to buy a gently used atv (mint condition with a couple hundred miles on it) instead of paying the full price just to drive it off the dealership floor but thats just me..

great advice and is similar to what ive said. i think the parents know what their kids can and cant handle.. i was 13 when i started riding atvs and i learned on a sportsman 500cc. at 14 i bought a kawasaki bayou 300 and now at 17 ive owned over 15 atvs and currently have two scrambler 850s. the key is to have a governor on that throttle thumb and know the machines limits.

George Fitzhugh (pro slavery historian that lived before and during the civil war) had it right that "slavery is socialism at its finest" He also portrays the liberals goals in government perfectly: "'It is the duty of society to protect the weak;' but protection cannot be efficient without the power of control; therefore, 'It is the duty of society to enslave the weak.' what do they teach kids in public schools these days? im sure i would have never even heard of this guy had i been in the public school system growing up

the only reason hidin biden is anywhere close to beating trump is the media, social media, the medical field, the government, and even many of the military leaders are anti trump. there where two voting groups in this election- pro trump folks and anti-trump folks and the anti-trump folks can be divided into two groups, either misled by the media, medical feild, and social media or anti-American radical leftists who think socialism works. if joe and the hoe win, its gonna suck having a president (who cant hardly remember his own name not to mention who his mom is or who hes running against) trying to run the country propped up by his crutches the media, social media, and the medical field.

welcome welcome

Y’all missed out had a great time FullSizeRender.mov FullSizeRender.mov

ive noticed an influx of buying/selling in the used atv world too (i live in southern VA). i think youre correct on the reasons but wanted to add one more- with all the attractions and everything being shut down for this scamdemic.. ive heard RV sales are through the roof and offroad vehicles including SXSs and ATVs also. (i say scamdemic because i think the COVID 'pandemic' was blown out of proportion by the media- dont get me wrong i think COVID is serious just like the flu, but i dont think its necessary nor prevents the spread to try and close everything down) -just wanted to clarify

hey know its short notice but me and my dad are headed to busco beach this weekend. plan on riding saturday the 17th (10-17-20). just thought about throwing this out there if anyone wants some last minute riding plans in NC! also ill post here again if i plan to ride somewhere or at busco again in the future.. sorry for the short notice!

i dont see the wiring diagram in the manual which surprises me. it even has a electrical section where i thought it would be but ive searched through the whole manual to no avail. guess ill have to look on good ol' images and try and find one lol

welcome back brother. cant wait to here some good stories!

ok thanks. i did download the manual from here and am going through it. i assume there would be a wiring diagram in there?

hows the best way to check to make sure the wires are not crossed?
