But if we say it's a wast to put money into a 250 then we are also saying it's a waste to put money into a 400ex when we should just buy yamaha 700s and build them.
Who can we ask to build a better cam for the 250x / ex.
yes and NO
and the reason is this, the 250x is basically an entry level atv, a 400 ex, at the time it came out was the flagship of honda's race atv's
better shocks, frame, design and all that
BUT if you read up on things, odds are you will hear MANY experienced folks tell you, before sinking money into a 400 ex, your better off getting a 450, and I agree!
as your getting a lot of updates and NOT just power mods for your money!
same would be with uping from a 250 to a 400 or larger
your getting MORE than just more HP, your getting a whole better machine in many other ways!
SO< again, IMO< its about Bang for MY dollar, and what will get me the most from the money I am spending!
Yes you can MAKE a 250 get more HP, , but in the end, will you spend more money to have a 250 with more hp, and lesser other things, than you would have spent just upgrading the whole atv to a larger displacement one of a different era and design to the atv itself!
so, the logic here doesn't be as simple as you want it to be!
I am NOT against doing HP mod's to some things
some things wake up better than others
but if your a growing person, odds are what ever HP gains you get from a 250, you will soon outgrow and be out the money you put in and most mods never get any real return on the $$ spent on them at sale time!
and MOST most to a motor, will also lessen motor's life span!
all the more so on smaller cc motor's you tweak
as you will be driving them Harder and harder, causer you CAN, where larger cc motor's/HP , are many times hard if not impossible to run full throttle all over the place like you can on smaller motored of like toys!(I raced 80-125-250-500 cc MX bikes for 20+ yrs, so I know this for a FACT, I could run a 125 balls out, and need a top end pretty fast, but my 500's would go for yrs and yrs,(if I wanted to) cause NO where to open them up as often! or run them as hard as I could on smaller HP bikes!(even on almost exact chassis's )
