Oh grand & wise 3wheeler guy, I need help!!

[Nicoride]

Tell me this: 84 250r if I raise the 6.6-1 compression up=more horse power or bad idea? I would like my old 250r tricycle to beat my friend's 660 craptor. Is this possible?

Prolly going to need more then a little bump in compression. Is any thing done to it?

[Nicoride]

No she's all stock right now except for the plastic tank, but Ive found another motor for the build up. So far
I've got new .06 piston,larger 86 250r carb with 1/2 spacer,D&G boost bottle setup,D&G exhaust silencer and I'm making a +8'' longer control arm

The extended swinger will help ALOT on the holeshot. But you will need more in the lines of big-bore HP to beat a Craptor.

If you had a liquid cooled R there are MANY options for big bores and the like... But your Air-Hammer is kind of holding you back on that. Try to find a Honda 300 Big Bore for your '84, but my bet is it likely still won't be quite be enough unless you have all the right supporting mods and dialed in real good...
