I am looking to do some improvements and was wondering about what sort of improvements are doable to improve the bike.
I have heard about moving foot pegs, increasing rear shock length, some throttle mods to change it to a 1/4 throttle along with flywheel mods and big boring with a dt piston.
Are these mods good or bad and what are the measurements if they work well.
Also any other modifications you can think of would be appreciated.
Is the question the OP asked, and I have tried to answer based on my own first hand personal experience. Modifications to a bike are certainly an area where everyone has a view, and clearly those who are happy to ride original bikes in standard form are going to have opinions which differ greatly from those who feel the stock bike is lacking and might benefit from alterations.
