I am a 55 year old u.s. Taxpaying registered voter who has been riding motorcycles for over 42 years. I have adequate health insurance,own my home,family man and have been at the same job for 28 years.I hate wearing motorcycle helmets and hate even more,the government telling me that I have to wear one when I ride my…
I want to complain about mandatory use of motorcycle helmets. I believe any person who is legally operating a properly registered, licensed and insured motorcycle should have the right to decide for him or herself if he/she wants to wear a helmet or not.
There is a company - dna specialty inc. 1415 w. 178th st. Gardena [ZIP] tel: (310) 767 - 4070 fax: (310) 767 - 4091 world wide toll: (800) 608 - 4446 making "sealed spoke wheels" for motorcycles so they run without tubes. The problem is, they are not being sealed correctly and leaking air!! Not a huge deal for me...
Tl* the contact owns a 2005 harley davidson sportster 1200 custom motorcycle. The transmission would not down shift to 3rd gear because it would lock. The contact would have to up shift to fourth and fifth gear before down shifting to first gear. This went on for a month.
The vehicle intermittently failed to turn off or start and lost power while driving at various speeds. After inspecting the vehicle the dealership replaced the fuel valve, the drive belt and adjusted the timing. The problems still exists and the vehicle has not been returned to the dealer.
Not long after my 1000 mile new vehicle checkup, my 2005 xl883r sportster's front brake lever would collapse to the handle bar. The front brake would operate, but the lever would not return to the regular position. Also the brake light would stay on.
It wa s a terrible rattle and ringing in the transmission. Motorcycle was stalling in the middle of the road. It would make a noise and die in the middle of the road. The dealership took care of the stalling, and it was now not as bad, but is still stalling/ cracking/rattling, and ringing worse.
