If I may offer a suggestion! If your still in Thailand Change the front tire. If you have a meztler on it they are good in a burn pile

Drop the 140 and ride it so you can judge what you want to do. Its like night and day just with the tire change. Springs are great in the front but if you have a chance to add any adjustable high speed dampening I highly recommend it over just a spring change!!!! I ride on roads now I would have avoided before just to save my kidneys. Oh that and ever since I wrecked my 05 in Siberia oops I mean Canada where I broke my back in six places it has not been as kipper
