I was trying to do the same thing with a XT550 years ago, took it to a alloy fabricator and expliained how heavy it was and that I wanted to exchange this and that with alloy to make it lighter......to which he just looked me up and down and said "Well there's 20kg it could do without right there" cheeky barstard, I spent a fortune there getting the piss taken out of  :)

Hi I have just finished my XL250 project and had the same idea about getting it lighter, but I keep the original frame and ground off everything that was not needed, side stand, frame lugs, brackets etc. The steel tank was replaced with a plastic item, the original seat weighs heaps so I used a plastic base seat from an early 80's KX. Numerous other steel parts have been remade in alloy. In the end though your still dealing with heavy engine so you have to get used to it. The XL250 handles grass track coarses very well and is great fun to ride and well worth the effort.

Here is my recently completed/ ongoing xl 262..

maico 72/73? frame, venolia 75.5 mm piston, megacycle B40 cam, 1mm o/s inlet valves,matched porting, electronic button rotor ignition, swiss designed & inspired exhaust (1 5/8" and 4  1/4 "megaphone) , 36mm carb on methanol. Many thanks to Swiss for advice on the motor and keeping me on track when I got impatient!!
back wheel is tm 400..(wanted a mudcatcher rim to match the front.)
It was a partly done project which I got , which I got in Feb and got it  running 2 days before the nats.. motor has a good wide powerband, but is horrendously thirsty..

Its good , turns very  nicely but was too low, no paint left on the underframe.. and I think it put me on my bum once because of the frame htting the ground - the action pic shows the frame almost touching the ground.
 Also black marks under the guard tell a story. the swing arm as far as I can tell is a xl/maico combo with the lower shock point pretty low. Lots of things fell off that weekend..including the seat in one race..!!

I had Too many other things to do and the height/ shock position slipped through the cracks.
The muffler is as ugly as sin, but I had no time to anything else .. and it was LOUD through the open megaphone..

Last photo shows rearranged swingarm with lower shock mount  back  to a maico spec. and shocks extended by 20 mm. 101 mm travel now , with no springs..!

Not ridden yet since the rework...double the dirt coming up so the next outing is dirt track..yee hah!

Wow! thats a cool XL mate, the engine sits in the frame very neatly. I'm interested in the where and how of your ignition system you have. Sorry for the hijack Bigtoe ;)

Its a HPI universal 4 stroke igniton from belguim . Ar0und $220. supplied with a blank rotor and mounting plate both machined to suit.

the cradle has been extended to fit the motor, hence poor ground clearance.

not my thread - so no hijack - bring on the xls!
