Bigger carb and cam and a beefier crank (I think).

 

His modded nonHO would outrun a stock HO. Just get the parts Offrder15 suggested and you will take him.

 

That price did sound good, too bad, also check bluebook prices on Kelly or NADA accessible in the classifieds on this site.
The dealer will offer you considerably less for a trade in.

I would also look to go concentric drive and the HO version or better yet the 400 2 stroke , with just a trail pipe and clutching you will blow him away!

I picked up my 2000 2x4 for 2k (was asking $2,500). Best buy I ever made! [img]i/expressions/face-icon-small-happy.gif[/img]
