i did this about 3 weeks ago. i robbed a perch and lever off of an old dirtbike idk what year but it was a yamaha mx175. you have to be careful when you do this, you have to make sure the lever is long enough to reach around yout throttle assembly. since dirtbikes have twist throttles they make the levers shorter. the lever i have is a little too short, i had to grind down the top so that it would slide under my throttle assembly a little bit so that it wouldnt hit when i pulled it in. i only have a 2 finger pull because its so short but i got used to it and i actually prefer it now. hyro is the way to go but i cant afford it so i make doI:I
