the problem with 4 pokes is yeah they are slow. that's why when they stopped making 2 cycle engines for the u.s. they started making 4 cycle engines larger in cc.
they knew that a 200cc 4 cycle engine just couldn't compete at the same rate of performance that a 2cycle 200cc could.
My 12 year old has outrun the 300ex with his stock blaster time and time again.
even if this guy has bored his out .70 over he is still riding a weaker machine.
you have yours bored .60 over with 20 off the head. that really produces some donkeys in a 2 cycle.
but don 't run octane boost you should beat him hands down even if this monkey has a hot cam.
another trick you could do and probably should do, is either slot your stator plate so you can advance the timing a little or buy a "ricky stator" slotted plate to do this with.
but you wont need it for this race. just lay on the handlebars, and really put some weight on the front end.
remember his 4 cycle doesn't have as much torque off the line so he wont have to worry so much about his front end coming up, as you will with your blaster.
also you can lower your blaster and it wont stand up as much on take off.
I have lowered mine and it's alot more difficult to get mine to stand up.
means i get better off the line with less worry of eating the handlebars on take off.
and just like any drag race, the racers release the clutch until just before it engages so that the clutch is already grabbing just a little, so that you get a good off the line with less snatch in the rear end. the more the engine snatches against the rear end the more likely it is to stand up.
so give a good amount of throttle, hold down your rear brakes and begin to let out the clutch until it grabs a little, keep the throttle on and the bike still until time to launch, when you launch let go of the brake and clutch and go full throttle,
you should tear him a new one, and make him either give tons of excuses for why he lost or at least limp home quietly with his tail between his legs.
practice this and get good at it, you'll make him look like he is riding 50cc.
