hey guys,been reading this site about a year and finally joined 2 days ago.i have a kdx 220 04 stock and after looking at this awsum site know the top end will last me about 3000 miles as 95% of my riding is road use here in the uk.but how long does bottom end,bigends, main bearings ect last?i use castrol tts 40:1.oh yer bike goes awsum on and off road,was amazed how easy it wheelies in 2nd and 3rd,allways puts a big grin on my face.1 more question,slow speeds,1/4 throttle cruzin, bike seems to chugger but soon as i open throttle it goes,is this just the way they are?i have had bike 3 months and love it.
