Did some body / bondo blending of some imperfections on the flat black area of left & right side air intake panels where some of the outer carbon fiber delaminated from the polystyrene.  |

Decided to make internal modifications to the dual mufflers. Been driving the RT for over a year now and I have always had excessive backfiring when suddenly releasing the throttle. The 2 mufflers I had purchased have a large 4" open chamber with damping ports and insulation around the perimeter to absorb the some of the combustion detonation sound. The original 600cc motorcycle had a single exhaust with 2 outlet ports. My goal was to reduce the backfiring and the overall decibel level of the exhaust, I would like to hear the traffic better, my stereo & maybe not wake up the neighbors when I head out to a car show at 7am! I looked at some internal aftermarket muffler silencers available and fabricated a similar design. Starting with 2" O.D. x 8" lg. x .040 wall stainless tubing, I drilled a series of 3/8" holes 3/4" apart around the perimeter of the tubing. Then made a cross mount bracket that supports the baffle from the outer end of the muffler. The tubing was then wrapped with approx. 6 layers of high temperature rated fiberglass cloth. Finally Stainless wire is wrapped around the cloth to hold it in place, the assembly is held inside the back of the muffler with two of the opposing mounted brackets with stainless allen head cap screws. I put about 50 miles on the RT since completing it and I'm very happy with the results, the decibel level is about 30 to 40% lower, the backfiring is practically non existent and it appears the low end torque has improved!   |

It sounds (no pun) like there was a pin hole allowing air in the pipes and it was detonating the unburnt fuel inside the mufflers.
None of these pictures are showing up for me so I went and looked at the BBCode and it is like 1 whole page of "jste,mcn>hdt/lsifyd" all jumboed together.

In the process of making T-Rex body design modifications to existing, will be finished for the 2020 model year, LOL. Will post pic's soon, in the meantime wishing everyone a very Merry Christmas and a Happy New Year!   |

Made body modifications & new paint job to T-Rex styled trike, thinking of calling it the "Manta-Ray Trike". also new more aggressive tail light assembly. The West Marine epoxy body finish after 2+ years was yellowing badly even though it was supposed to be UV stable. Had to Bondo skim coat the carbon fiber surface for imperfections multiple times, sand, self etching primer, sprayed marine grade self leveling oil base white paint plus epoxy clear coat. Body work is not my specialty, but I'm happy with the finish, I call it the ten foot paint job, since it looks flawless from 10 or more feet away. I should be taking it to a car show by the end of this week, so will see how it does. Generally the vehicles at most car shows get critique based on body finish as a primary factor, but I'm always competing with factory made cars with professional paint jobs. Hopefully the new paint will have hidden most of the flaws from the original carbon fiber layup. I did get a fairly good response from Face Book posts so far on the modified design style. The Rear body still raises up by remote control and the new tail light assembly along with the backup camera remain stationary below. Just glad to have it back on the road!
