lol, these types of threads always crack me up..
you've answered your own question several times already..
besides your talking about different ride styles..
minis aren't the ideal trail bikes specially when tryin to keep up with big jap bikes.
you'll toast the engine and chassis 10 times quicker keeping up to big jap bikes or mx track built mini.
and unfortunately no matter how much work you do to a mini engine its not going to make it a better trail bike..there just not made for it.. the chassis design is just wrong..
ok so you dont ride the wr much but when you do its awesome.... keep it because your not going to sell it for enough to buy a decent 10'er and upgrade the revmx.. plus the wr will last ages because your not putting many hrs on it.
just slowly work at upgrading the bikes as time goes on.. in the mean time race, race, race. you'll be a better rider while riding a non modded mini and then when the upgrades go on your riding progresses as well..
