first off- this site is great- i have been doing all sorts of lerking around here over the past couple weeks- all sorts of good information- finally decided it would be a good idea for me to go ahead and join.
now for a little background on my 250x. i have had several 4-wheelers and dirt bikes over the years- all of which stock besides the usual pipe and filter. i just recently sold my dr350 and had some $$$ burning a hole in my pocket- and eventually got the itch to play on 4 wheels rather than two. a guy i know had a bone stock cherry 250x that he bought new and rarely rode. he let is son in law use it for the weekend- and he managed to run it out of oil- i dont know the entire story as to how this happened- nor do i care. the owner then went and bought all new everything- bearings, clutch plates, had the cylinder bored once over, a new piston,- the whole bit. before he started to re-assemble this thing- he and his wife split up (again- dont know the whole story- nor am i all that concerned:devil: ). he decided to sell it since he never had the time or the desire to ride any more. i asked him how much- he said if i had $300 in my pocket i could have it. well- it was on a friday after i had just cashed my check- so i went home with a 250x. now all i have to do is figure out how to get it back together from scratch. on the plus side he did have a honda factory shop manual. wish me luck boys:D
i bought this with the plan of just putting it back together- and just keeping it stock- besides a pipe and filter. well- much like everything else i own (ford focus, 383 s-10, fzr600- all of which anything but stock and on the bottle)- i have talked myself into thinking a stock 250x just wasnt my thing.
i am going with this route:
sparks pipe, k&n, wb 245 cam, p&p head, etc.- and a little higher compression just not sure how:confused:
i read the entire article on head decking in the FAQ section- but i am a little on the confused side- since that was mainly aimed for the 400ex. i dont want to get a higher compression piston since the one i have is new and the cylinder is fresh, nor do i want to go with a more radical cam (i know this has nothing to do with the compression- i was just making a statement as to why i didnt choose a little more cam) since the valve springs/guides/retainers are also all new- and i dont want to replace them with aftermarket stuff. i also have a complete gasket and seal kit from k&s (they sell all sort of gaskets and such on ebay). ok- no onto my real question- in order to get a little more compression- i plan on taking the base gasket out and just using rtv sealant of some sort (when they say the base gasket i am assuming they are talking about the gasket the goes between the cylinder and the bottom end of the engine?) i have access to a machine shop to have the cylinder or head decked- i know the guy that owns it- and he does simple stuff for free for me. but my question is- do i have some taken off of the top of the cylinder or the bottom of the head? also- how much do i have taken off? how much does the compression go up for every thousandth (*sp?) taken off? i am going to go with the decking/milling route rather than a thinner gasket since i already have the head gasket and the machine work is/will be free.
thanks in advance for anyone that can help-
