Fit a full DEP system but I don't recommend fitting aftermarket air filters as you'll melt the piston. Instead, remove your seat and you'll find a rubber tube going into the top of the airbox. Pull that off and it'll allow a perfect amount of air flow and then you just need to rejet the carb and away you go.

Willenium Posted February 7, 2007 Posted February 7, 2007 I'm not 100% sure that it is a 125 main jet so you'll need to whip out the carb and confirm that. Going up 2-3 jet sizes should be sufficient (e.g 135 or 140). Just check with the shop what increments the jet sizes go up in and I'll be able to point you in the right direction. With my DTR they went up in tens so the next size up from my standard 240 would have been a 250. Sometimes they go up in fives so just check with them.
