like they say on 4 strokes you gotta go get valve jobs, and they cost bout 300 they say? well what does the mechanic do? can it be done at home and your just adjusting them?
i'm 18 and race a crf40r i admire the motorbike. in case you desire to flow extra decrease priced i might decide for 2 stroke. have faith it or not 2 stroke is extra maintence even though it is lots extra decrease priced to rebuild. A 2 stroke on long tracks with enormous sweapers is purely as speedy as a 450 if not speedier. I enjoyed my 250 haha. 450's are somewhat a combat on the song they supply a real undesirable arm pump by using engine breaking. and 250 4 strokes are like driving the previous one hundred twenty five's all you do is shift. in case you may desire to get an rm 250 2 stroke they have the extra appropriate potential bands and have very solid bottomw end.
Take the head to a machine shop you have to grind the valves or replace then,Same with the seats Then replace the guides and adjust the valves Not a driveway Job
