Si S2 differences

[carlos fandango]

Hi Just got a series 1 never had one before.
What are the differences between S1 and S2 bodywork (apart from the obvious, Headlamp etc.)
Its a 59 li 150, so not a frame breather.
Cheers

i think ,and i mean i think there's a slight difference in the frame tube just ahead of the cylinder ,s1 cylinders are shorter and i believe this makes s2/3 motors a bugger to fit ,i am basing this purely on the feature i read about that tzr lammy thing in scootering(c1989)as the guy that built it (reg?)reckoned to have had to reposition the spark plug as it was based on a s1 frame

i have a ser. 1 li and i have finished restoring it last summer. used the o.g. case and put a deanspeed 190 cylinder kit on and had no clearance problems. the o.g. cylinder was definatly shorter. i don't think the tube is any different. that being said though, mine is a '59 and maybe the early ser. 1 were different.

I dont think there is a difference on the tube around the cylinder either.
I meant the the body panels more, eg legshields, front mudgaurd, panels,runner boards, rear light, etc.

as i said i was only quoting the feature in scootering

I spoke to him at the aberystwyth scooter run in the 80's........his frame was a TV series 1 hence the clearance issue.

only difference between the LI series 1 / 2 is the horncase and wiring brackets on the frame, the open grille on the rear of the S1 is covered in on the S2 and they both use different chrome rings. And of course the S1 framebreathers have a bloody bighole in the frame

I have a Sil casing and RB kit on my Li 150 S1(59mod). No problem with the fittings.

Thanks Dibsey thats more of the type of information i was after.
as i need a new panel and a few other bits, and was wondering if s2 bits fit, as most dealers only state s2 on parts

[carlos fandango]

Hi stian thats a coincidence ive got a rb20 to go in it
can you use the s3 sidecasing with the flatter kickstart buffer, or do you have to use the s1/s2 one with the buffer part that sticks out?

I use a Li125 S.3 sidecasing, but i had to trim the footboard i bit... I preferd to do so, insted off breaking the casing around the kick aksel one day...
