Installed a Coffman Slip on exhaust this past weekend. Do I need a tuner or will she be safe staying stock?

Thanks

Should be safe stock. Never heard anyone run dangerously lean on stock fueling with slip-ons or even a full system.

Putting in a high flow air filter and putting her on the Dyno April 10th or so. I will post up what I come up with. Purchased the Woolrich Racing Interface and Harness Package so I can retune if I decide to do more upgrades in the future.
Thanks

That is the rout I would go if I hadn't already gone the DJ rout years ago. I will do the whole Woolich system on my next bike when ever that might happen.

Good luck. Let us know how it goes.

Just installed a used set of these slip ons and love them, hate the kickstand whackin it everytime though. Any one got a good idea of the washer shim trick? I got 3 washers on the rear ward bolt, between the kick stand mount and frame, any ideas on if your supposed to put washers on the front one too, or just keep adding washers till it doesn't hit anymore?

I believe there were 4-5 washers with mine. Put all of them on the back and it worked perfect.

Dyno tuning is complete. Coffman slip on and BMC air filter

I have the exact same set up! You don't happen to have a copy of your fuel and timing maps do you?!
