I have been a loyal HuskyWR250 2 stroke rider for the past 5 years and decided to make a move to a Yamaha WR426 2001 (will get it this week)!. My former Husky pals tried to pursuade me to the Husky 400T, but I decided not to. Can I roost the Husky 400T with my WR426? This site is really cool and all that I have looked for in my entire 15yrs enduro expirience. Can someone tell this rookie 4T rider how the 426 should be properly warmed up. Can I leave it run idle, or better better not (like 2 strokes varying revs), for how long it needs to run after a cold "Brazilian temparature" start? What minimum octanage fuel should I run, as fuels come in different qualities here in Brazil.
