I just got a project lt80 needs some work it's a 87 what did I expect
Chain is real loose and rear sprocket missing teeth stock size I think it is 26 rear and 17 front
I have seen adds for 10 front and 22 rear is this good or should I stay with stock ?
also I read to change to a #40 chain from the 520

thanks for your help

Don't know the sprocket size or changing chain size questions you're asking. I wonder if your nearest Suzuki dealer can help with your "back to factory" questions??? Based on previous posts, I get the impression that many are pleased with their sprocket chain size and sprocket sizes / gearing of their LT80.

I do know that some LT80 folks like to install a fixed chain roller on the LT80s. This fixed roller reduces chain slack and thus, reduces faster wear on the chain. Also eliminates the need to use 1/2 links. For pictures how others installed a chain roller, surf:

Hope the idea of a fixed chain roller helps....

If you do go with a #40 chain then you will have to change out the sprockets to a 428 to make work with the chain. The 520 chain won't work. If you are just wanting something reliable then I would just go back to stock gearing. With the stock 520 chain and sprockets. The 428 sprockets and #40 chain won't last as long. You should be able to find this either thru your dealer or Rocky Mountain ATV.

This is a good place for Original stock equipment or "OEM".

The only reason to get 428 sprockets and 40 chain is to be able to use halflinks in the #40 chain. Other wise just stick with the 520 chain and sprockets or if it's cheaper get the 428 chain and 428 sprockets. 428 chain is stronger than #40 chain. It does cost more, but if your not racing, it should last for some time. Use the chain roller ( i like the one that forces the chain more in a figure that looks like the letter B. It forces more of the chain against the teeth of sprockets.) and have fun.

 

Sprockets: Stock ratio is a 10 front and a 22 rear. I also agree that if the ATV's stock, I'd just buy the stock ratio stuff (520 size). Later if/when the little guy starts driving the dog shiz out of it, you probably will be doing a whole lot more to it IE: front & rear clutch mods, pipe Etc. At that time... you may want to switch to the 428 size gearing parts (less rotating weight). Also a chain roller setup is a good idea. If or when you do it, "slot" the plate. That way you'll have adjustablity should you want to change gear ratio's in the future.

I have heard the stock is 10 X 22 , but my early 87 yr lt80 has 17 X26
Will the 10 X 22 give me the same gearing and do I need an o ring chain ??
thanks for you help

 

Yours is a little high geared, but i'm not sure if it made much of a performance difference. It would give up some bottom end for top speed. As long as the motor is still sound I would try to go back to stock gearing. At least you would be able to up the gearing as needed. I can't remember if ours had O ring chain or not, but if clearance was not an issue I would get O ring chain. Anybody know what the stock pitch was? I've got some new left over chain I'd give you if it's it's got enough pins. I got like 30 links left.

 

so you are saying that 10X22 is a lower gearing , more bottom end , slower top speed ?
just what I'm after , don't need this thing going fast grandson is only 5
what is an o ring chain ??? and why do I want that
thanks

 

Yes 10/22 would be lower geared. 2.2 :1 versus 1.53 :1. O ring chains have O rings in between the inner and outer side plates. This keeps dirt and moister out of the pins. They are pre-greased internally. This cut's down on noise, wear, and chain binding and kinking. You still lubricate the outside as neaded.
