Hi, new to thumper talk and I was just lookin to get some advice about mods and tech tips. So I just picked up a new 09 drz-400s and was wondering how I can get a little more snap out of it by making some minor tweaks (preferably the ones that cost little to nothing) Ive heard I can make some of these tweaks to the exhaust and air box but im not sure what. If there is anything else please feel free to state them. Its coming up to its first oil change so I was also wondering if fully synthetic oil was a good choice to run in this bike, and if so what brand and what oil filter would I use. My last question is about valve adjustment, roughly how many K would I need to make adjustments and how would I go about doing this. Thankyou in advance for the advice.
