| The first thing you could do is change the exhaust and manifold for less restrictive ones. But bear in mind though that doing so you will need to notify your insurance company which will push your premium up. You'll only gain a few more horses though! I'm sure someone else will be along to tell you some other potential gain ideas!! Good luck! And welcome

| ZR - that'd be one of the little two-strokes, then? Depends how much you want to spend and how happy you are to take it all to bits...but the basic options are: - Up the intake with bigger carburettor or main jet plus inlet manifold, bigger airbox, performance air filter, replace the reed valve, get the head ported and flowed, grind the inlet/exhaust ports to a larger size - Get better detonation - fit a performance spark plug, flow the compression chamber, fit a racing piston - Replace the exhaust with a performance expansion chamber (needs to be tuned for the bike) plus exhaust manifold - Balance/grind the crank - Big-bore kit - take it out to 80cc or thereabouts. A lot of the engine work is best left to the pros: you could do a lot worse than contact somebody like Stan Stephens Tuning for an idea of what package they'd recommend for your particular bike, then decide what you want to do with it. Oil - pretty much whatever you like as long as it's fully synthetic and you make sure it's either already running fully synth or completely drain the engine before adding the new stuff. Putoline seems to be quite highly recommended as a brand. If it does more than 30mph it's no longer legally a moped, if that makes any difference to you.

| For the first time in decades, the fate of American foreign aid to Egypt, a total of $1.3 billion annually, hovered over the administration’s deliberations. Because of a new Congressional restriction that requires the State Department to certify that Egypt’s government is committed to democracy.
