When accelerating hard my L1 gets very juddery from about 7000-10,000 rpm, Over about 10,000 revs its perfect and pulls hard. its completely de-restricted and has a K&N and sports can.
Anyone know why it would judder so bad?
It feels a bit like my old suzuki Rg 125 when the power valve was opening, went rather juddery.
Im a bit baffled!
Thanx, Guys+Gals!!
Juddery on full throttle

i get exactly those symptoms when i forget to replace the 2 blank-off plugs in the top of my airbox, or if i remove the little snorkel/ pipe thingy in the front of the airbox (removed it coz i thought bike would breath better, got nice torque low down but ran crap above 6000 7000 so put it back immediately)
basically the whole induction, exhaust system is very sensitive to changes.

yes.
makes a big difference. when i got my bike had same symptoms as yours, cause 1 of the blankoffs were missing as well as was sucking air between carbs and airbox...
i made a gasket out of 5mm foam camping matress material (tested it was fuelproof by leaving in fuel for a few days). i needed to use thick material cause my airbox is slightly warped where it joins the carbs.
after sealing box revved sweetly all the way through... but like i said make sure u have the pipe in the front of the airbox as well, removing that causes same symptoms...
good luck.
