They weren't made for me personally. I'm just a customer. Dave Plummer on Facebook came up with the design. He makes and sells them. I modded them by rounding off the edges for smooth exhaust flow with hand file and emory cloth, and then stainless steel bead blasted them for a nicely uniform finish. I'm actually amazed at how well they work. I keep detailed gas mileage records and have not lost even one mpg with the inserts, even though the exhaust is way quieter. All other bd killers hurt performance... these don't.Are those the ones the machinist made for you or a TOCE brand variant? They look good.
Hi tooter, nice thorough thread. I admire your dedication to logging and sharing your life with your GROM.
I'm just wondering why you're giving the MPG so much attention? You noted you enjoy finding ways to be frugal in your everyday life (keeping/using an old fridge etc.), so I understand your interest from the money-saving point of view, but then you're spending money on the GROM like it's going out of fashion!
I'm not flaming by the way, I'm genuinely interested.
SuperTrapp has been doing it for decades.Tooter,
Thanks for posting the video. I really think you may be on to something: offer after-market exhausts which allow the end-user to tune/adjust the sound to their own liking. I would very much like an after-market exhaust, but I need to keep my bike pretty quiet.
I really like your approach to the Toce; although I confess I don't know that I would be able to fabricate sound-reducing inserts such as you have done. Very cool work.
I know. I put Supertrapp tuning disks on my Ruckus and the engine performed great.SuperTrapp has been doing it for decades.
Quality exhausts like Yoshi include decibel reducers or baffles so you have two sound options.
But, as always, these options affect power as well as sound.
It's an ebay light for a Jeep Wrangler. The LEDs didn't burn out. They never lit up. They sent me a second one with exactly the same defect as the first one. I'm going to see if I can fix them. The kit was for an OG. I modified it to fit my SF. I really like the retro cafe racer look, and one way or another I'll get everything sorted out.The Monster Eye looks much better on the SF than I thought it would. It is concerning that 3 of the LEDs are already dead though. What brand is the light?
