Alright, Hello everyone.
I have a 2014 m1100/9000 whatever it is its the turbo 4 stroke haha
So it had a speedwerx 114/267 primary spring and 76g weights, 38p helix... it would tap the rev limiter once then hold steady on a wot pull.
Now it has some intake mods, aluminum charge tubes, c3 belt...
It depends what you want really.
The more bells and whistles the more they cost.
The lights I posted were under 300$ in parts. And took a couple evenings at work (camp job) to complete. The wiring took a while because of the halo ring running lights that are also switchback led turn signals.
