The bike is a pyramid reed with a well broken in metrakit 65cc kit, phbg 19mm race carb, 118 main jet (witch seems big to me but any smaller the plug turns gray), 45 idle and the needle is a w9 all the way up. A homemade puch simonini pipe. tjt variator (2 green rollers filled with solder and 4 blue filled with resin all together they weigh about 2oz). I have machined some material off of the rear pulley for more low end. It

Timing?
The bike ran fine for years with the kit. I recently put the carb, pipe and variator on and that is when it started trying to kill me. I have cleaned and checked the points, but have not messed with the timing.
Nice bike If may say.
yah, really nice bike. How's the crank?
i have one i totally wanna kit! anything i should know!? viva la derbi dogg!
I am in love with your bike.
Check your timing, if you've been running the motor hard for a few years, your points cam may have worn, causing incorrect timing. Stock should be 1.8mm BTDC
crank seals?
I would get a degree wheel and dail the engine it..
Car jump pack to power the timing light gun
timing light
white paint marker(to mark the case and the magneto)
degree wheel
Hmm advancing it 10 degrees... is where you want to start..
This is a racing bike correct? or everyday rider?

Oh, i see. My bike would overheat sometimes because the weights were too light. Like, drastic difference. i don't run a pump on the H2o moby, nor an overflow tank, so when it overheats it dumps water out the pressure valve. A nice warning for seize prevention.
So yeah, i would say heavier weights/lighter spring.
Bret I think you are on to somthing.
And yes its an everyday rider.
Hey, sorry I can't help, but can you post a better pic of the bike? I need a new desktop image.
