Nice man! Stoked to see more people modifying these bikes. Don't see too many of them around.

Probably my most favorite engine ever.
Which 1100, L, M? Still pretty twitchy on the street but ideal for racing
It does have limitations but a dead reliable 140 bhp. (more with a modified 1200 Bandit motor)
Oil cooling isn't most efficient but beats the hell out of air cooled (unless ducted fan) One thing Suzuki did introduce to motorcycle world that 'everyone' now uses - under piston oil jets squirting on bottom of piston crown.
With modern low viscosity synthetic oils, heat transfer can be improved but still needs more oil cooler surface area than a water cooled motor
