I just bought my 84 Honda ATC 200X. What weight of oil should I use? As far as I know this is a low hour orignal engine. I get smoke on first fireup (valve guides?) but after that it's pretty clean!
Has anyone heard of moding a mono-shock? I have heard it is possible to install a schrader valve in the oil side of the shock so you can recharge the oil instead of spending the $700+ for a new one? Thanks

 

we ran 30 weight in our 200x's, all of them still are running today.

 

Did they kick over OK with the straight 30? Temps are dropping around 40deg. now and this thing is a bear to kick anyway(no compression release!)

 

we ran it stricly in our deserts so my example is pretty irrelivant i suppose. i could probably start it with my hand.

 

10w-40 will run just perfect in your machine. Summer or Winter time here in Ohio. Not sure about the shock, sorry.

 

I just bought an 84 200x also and the shop manual says to run 10w 40, but I suppose it may differ depending on temp

 

i run 10w-40 year round in my ATCs. i just use regular oil, but depending on how you ride you might want to use synthetic.

 

Thrash- I have run 10 40 with lucas hd oil stabilizer(quiets gearboxes, helps run cooler, etc). Im in S.E. Iowa, it gets pretty chilly, never had a problem kicking a bike with this setup. Cant help you with the mono shock mod, I would be interested in doing that too if anybody has any info on it!

 

I took the 200X out this weekend and used the 10W40.b Thanks to all !!!!! Have a question though.......The 200X normally have a LOUD timing chain? Runs good but you can hear the timing chain over the exaust! I hear the tentioners go bad?

 

10W - 40 is fine. Just make sure you check the oil every time you ride, because there is only a bit over a quart in the crankcase and if you run low you will starve it for oil and sieze the thing up.
