Make sure you have good fresh gas in it. Make sure your air filter is clean. Did it run good before and then all the sudden start running bad? Give us a little history on this trike, like it sat forever ect.....

I have been told its either the points or the valves need to be adjusted. I don't have a repair manual. If any one can talk me thru this process or scan and email me a section of there manaul would be great. If i'm way off base can some one point me in the right direction. Thanks for any help.
Here is a parts breakdown click here
Honda ATV Parts
put in the info of your ATV
A full tune up sounds like a charm
Clean the Air Filter
While your add it change the oil & New Gas
Change the Spark Plug gap... 0.028 in
Points Cap ... Gap... 0.014 in a little tricky getting them set patience is needed.
Adj Lifters (Valves) ... 0.004 in
Good Luck.
If you still have a problem Do a compression test lb/sq in.
120 to 130 is very good
115 to 120 is OK
110 to 115 less than OK

A great place for parts for your 70 is ( dratv.stores.yahoo.net ) I buy all my parts from them. I am also looking to buy a ATC 70 for my 2nd daughter if you are looking to sell it. :-)
