I feel stupid I had the longer spline collars on the wrong spots. I got it on now. Will report back when the 500 top end is on and running

Itd be different if you did these jobs all the time 😸

That's what I did with the wife's.   I actually had a 420 footshift with a cracked cylinder, so I had the wife's 420 cylinder bored and used it on that footshift, and bought a new 500 cylinder for the wife's.

 

I wonder what the 520 would do?   Looking at the chart @Melatv posted, the HP difference in the EFI 500 and 420 is negligible, but you're only actually going to a 475.  A 520 would be almost double the CC increase of the 500 cylinder.

Yea its too bad the 520 wasnt out when we did the change, but he had his mind made up, i couldnt change it 😬

it truly boggles my one brain cell, trying to figure out why atv owners who ride an utility atv, want to '' get that one extra hp '' ?!..lol. you can only get so much from these machines, after that..its all over but the crying. soo..bottom line: don't bother trying to get 100 hp from an engine that is designed to give you 10 hp..lol.

I hear that, i did try to get him to buy a bigger machine, but the kit he found online was a lot cheaper than buying another wheeler. The difference in power was deff noticeable. I have video proof! Honest! 😹

Ive done it with a kit from a Kentucky dealer. No issues with the machine after doing it.  Fi model. Its really 475cc vs the 420.

Another thing also to look is the battery condition. Weak batt they wont shift as easy. How old is the engine oil?

these models do not have a pull cord, ele and kick start only.

Frig i forgot, & I even had one of these lol

Sounds silly but, any chance the batt is reversed? Can you use the pull cord to get it going with the key on?

I had a 16 with ES, nice riding, but i would keep the old one until you were sure it was time to unload it.

Welcome! Hey...that ATC110 wasnt used in the "In a Big Country" video was it? 😅

Nice! Great bikes! I had a new one in late 2001. Abused the crap out of it. 

This is a buddy of mines pic. You can see part of the flame on the lower left (7 o'clock)

I took a video with my A51 but for some reason there were 2 objects in the sky lol..tho i did see a star below to the right. There was a flame i could see with the naked eye for a bit on around 7 o'clock of the moon/sun during the eclipse looking with the naked eye.

Yup, g/f and I biked up by the dam to watch, bunch of ppl already there. Got real dark & cold all at once. Quite the site!

Yea we are in there too with TBR. Schools getting out 3hrs early today. I have my welding helmet with me lol 😎🎇

I doubt theres enough traffic to add an ATC section. But doesnt matter to me really.

i'll try & get on tonight.

My ATV was only running on 1 cylinder.. not sure why 🤣😂

Biker on my FB in England posted today his town got the contract to build these things. 

Ouuu red, 81-82. Gotta be worth a bit.

😬

I did work on big trucks at a shop when i was 19-20, but that was a millennium ago  😅

Guy a couple houses up had a few KWs. Had a new metallic green one with black stripes (all were cabovers) back in the 70s, same idea as BJ & the Bear. I used to love that truck.

I dont know too much about trucks TBH :O 

Looks like the  old 81 or 82 185 or 200. Has the compression release on the top right, so likely the 200. Older tank off a 70s ATC90.

😯

Ive seen ppl use a small car battery in parallel so i know that works. Likely dont need anything too big.
