250x questions

[QuadOwner]

im reading a lot that the 250x had slight changes from say 87 to a 92. some say the 87 has a hotter cam, some say they all do over a 300. i heard the 87 has adjustable camber rest dont. now i know the jetting is different from 87-88 to 91-92, but what else? also besides the compression, 36cc, and kickstart, what else is really different from the 300? is the cam really hotter? long winded i know... thanks

The 87 has a slightly higher rev limiter(500rpm) adjustable ball joints in the arms, a freer flowing stock muffler so they are maybe a horse more power than a 300ex. PS the rev boxes do not interchange .

so only the 87 has those differences u mentioned? also what is the actual rev limit? on gt thunder it shows just over 9000 for a 300 and just over 10,000 on a 250. seems high?
