Holy rinky dink, I'd ratehr buy one of those vacuum pumps to change the oil!!!

 

On my wifes quad on the left hand side while sitting on it, below the CVT drive cover is a 17mm head bolt that I used to drain it's oil. It is toward's the back of the engine.

 

Yes, the one below the oil fill is the drain. If I remember, the spring is holding the screen.

After it is broke in I would switch to synthetic. IMMEDIATELY change the airbox to a K&N.
as stated in other threads my buggy with the same engine smokes like a chimney after my
airbox let in huge amounts of dust. Not a problem for me, but those riding behind me get
smoke in the face (at least until the oil burns off, most likely the valves). If you can get a
pipe for it to go along with the k&n (or unifilter) this will improve performance. You will need to
re-jet though.

If you take your stock pipe off and see a large weld restricting airflow where it comes off the
cylinder head, grind it down, this will make an improvement also.

cheap mods for a cheap but fun engine!

That link you have provided is awesome for those of us with this engine.

 

Are the 150 nice bikes even though they lack reverse? PLEASE HELP!!!!

 

I have the 150 with no reverse. It is a slight pain, compared to my Honda 250 with reverse. I use the "foot on the front wheel reverse" to get it off the trailer. If it were for me, I'd want reverse. It doesn't seem to matter to my son, he is always smiling anyway.

 

My wife is happy with her 150. She finds it to be a nuisance to not have reverse, but it is not unbearable. She likes the full-auto transmission more than she misses reverse. HTH.
