I thought I fixed the problem with mine when I tightened a loose bolt that holds the top timing chain gear onto the cam but that bolt keeps coming loose and if its loose at all then the gear will just spin on the bolt and won't turn the cam and the valves won't move. If the engine turns over then that is enough to loosen it, idk why this is happening..... any help please??? I wanna bog this thing!

this pic shows the gear and the bolt that holds it on I am talking about.

I am not familiar with the motor.

Is it missing a locating pin or key.

not that I can see, its just a bolt holding the gear onto the cam and its the pressure of the bolt pushing the gear onto the cam that makes it turn the cam, if it comes loose at all the gear just spins on the bolt, it seems like there might be a key way or a spline that might be stripped on the gear but how could that happen..... :(
 
from my top end rebuild of that lakota 300 we had, if i remember correctly, there is a locating pin on the back of the gear, that interlocks with a hole in the end of the camshaft, and thats what keeps it from spinning, apparently that pin is sheared on your gear, allowing it to spin, which is loosening the bolt
sounds like your gonna need a new gear

remove the gear to have a look at the back for the pin, or lack of now.
wrap a small piece of wire around the timing chain and tie it to the frame above, this keeps the chain from falling down in when removing the top gear,
and remember to align the timing marks when re-installing it

i have the lakota 300 manual uploaded to a file hosting website
PM me if you need access to it
it should be the same timing mark alignment procedure, and a host of other things in common with the bayou 220 engine
 
Nice, Awk! Beat me to it! There was a pin in there at some point, and if its sheared, you'll experience what you're, well....experiencing. I believe (don't quote me on this) that the pin in question on a Bayou 220 attaches to the driven end of the camshaft and engages the timing gear. On some engines, the pin can be removed and replaced separately. On others, you may have to buy a new camshaft. Either way, not a hard fix.
 
well I just put thread lock on the bolt and torqued it in there so I guess we'll have fun seeing how that goes. my friends dad that owns a quad shop here said to just do that, idk if he knows there is no pin for sure or forgot about it or what.
 
Ha! I got on Bikebandit and did a little looking. The camshaft on this engine has a built-in cam gear index pin. It is needed to keep the timing gear from spinning on the hub. Unfortunately, you can't buy a new pin by itself, but you CAN find a good used camshaft on ebay or elsewhere. Part # 12044-1211. Hope that helps! You're gonna have to eventually put a cam in the engine to solve the gear spin problem.

I cooooould drill a small hole into the gear and the cam shaft and machine my own key to fit in the gap

that'd work, but be sure it's aligned with the original so the timing marks will still be accurate
 
Ok so now I am trying to drill a hole into the timing chain gear and it is solid as hell, I burned out a standard high speed steel bit, and a cobalt bit, and my titanium ones are only scratching it, any suggestions? :(
