There is no L model listed for 1990. Theres an E model. Recheck the manufacturing date as listed on the VIN sticker on the steering head.MY BIKES..1977 GS 750 B, 1978 GS 1000 C (X2)
1978 GS 1000 E, 1979 GS 1000 S, 1973 Yamaha TX 750, 1977 Kawasaki KZ 650B1, 1975 Honda GL1000 Goldwing, 1983 CB 650SC Nighthawk, 1972 Honda CB 350K4, 74 Honda CB550
NEVER SNEAK UP ON A SLEEPING DOG..NOT EVEN YOUR OWN.
I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.

Reasonably sure it will fit, but just for kicks I punched the above link to Partzilla, It has a place to put in your bike to see if this part fits. I put in the info. it asks for. Motorsport, street, 1980, Suzuki, GS550L, and that site plainly says does not fit your 1980 Suzuki GS550L... Still be hard to believe it don't fit, heck it fits everything else.1983 GS1100E, 1983 CB1100F, 1991 GSX1100G, 1996 Kaw. ZL600 Eliminator, 1999 Bandit 1200S, 2005 Bandit 1200S, 2000 Kaw. ZRX 1100

Totally think this fits, just say'in if you put the info in that little box that says "check if this fits your ride" it says does not fit your 1980 Suzuki GS550L... Do see how this Partzilla ad may be confusing.1983 GS1100E, 1983 CB1100F, 1991 GSX1100G, 1996 Kaw. ZL600 Eliminator, 1999 Bandit 1200S, 2005 Bandit 1200S, 2000 Kaw. ZRX 1100
