XL250 Motosport - Performance ideas/help

[holeshot buddy]

my xl was out to 320 had a inch and three quarter tuned manderal pipe
38mm mikuni ported and flowed head  hot cam
lightened engine and frame
still ran points standard swing arm and cush drive
and was faster than a kitted 420xl 
lighter engine with less inertia and more revs
much quicker through and out of corners
i won that many races and titles on this bike
it was lots of fun shouldnt have sold it :'(

How's your XL coming along Jack?

Slooooooowwly........... ..........been busy with other stuff but will be back in the shed next weekend.

I got her going though and did a few laps of the paddock......feels hellishly slow after riding the XR650R......

I'm on a tight budget so she'll be a bit of a roughy.

I'm just gunna remove as much weight as I can off it and run it stock for a while.Thinking about pulling the magneto rotor off (it looks like it weighs a ton) and running a small battery and total loss ignition.Hopefully that'll allow her to rev up a bit quicker without losing too much bottom end
