i just got my first quad its a 89 trx 250r with a 86 top end bored .120 over. I am new to the atv and 2 stroke world and have a lot of questions about my new quad partly because i got it part way tore down .... but i put it back together.

1.... i put a brand new wiseco prolite piston in it but dont know how it should be broke in?

2.... it didnt come with a spark plug .... i dont have a clue what to use ?

3.... i was told it was a high comression motor and not to use anything less then 93 .... i dont know what fuel/oil mix to use or even brand oil?

4.... last question i have is i want to make sure its tuned right but dont have a clue where to start?

PLEASE HELP :D thanks ......!

duncan racing has a great break in process listed in their 2 stroke tech, should answer most of your questions
