lowbrow Posted August 26, 2015 Report Share Posted August 26, 2015 Welcome to the forum! It'll be a 2 stroke motor so you'll need to mix two stroke oil with the petrol. Enjoy! 1 Quote Link to comment Share on other sites More sharing options...

fivebrick Posted August 26, 2015 Report Share Posted August 26, 2015 Yes! DONT run the bike on straight gas. Put about an ounce and a half of 2 stroke oil per galllon. Quote Link to comment Share on other sites More sharing options...
sting32 Posted August 27, 2015 Report Share Posted August 27, 2015 (edited) Just FYI, when you ask questions, or if you read about posts about gasgas trials bikes, your 2001 is at least 2 years before the big engine change, from 2003 on, the newer engines and frames are referred to as "PRO" models yours is the older TXT. spains home website www.gasgasmotos.es Parts breakdowns (adobe PDF files you can save on your PC print or view) are here http://www.gasgasmotos.es/en/manuals/models-1-2001.html gasgas.com, which is usa's gasgas importer website has a "tech" button that takes you to this page, which was very popular when your bike was closer to being new. http://gasgas.com/tech.htm the only other 125, is the MUCH newer Radonne model which are electric start I hear, and 4 strokes, kind of the wife/minder bike all else fails when you need help or info... http://bfy.tw/1Vim (google is your friend) Edited August 27, 2015 by sting32 Quote Link to comment Share on other sites More sharing options...
