I got my electrics in and it starts right up!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I have not been able to ride this 120 in 3 years, and after spending 1000"s on starter and ring gears and batteries and such!!! Your the man and forever my brother! you ever get through Redding, look me up pal, I would love to buy you a beer or dinner! I am so excited that I could ride this tomorrow at 112 degree weather...I wont though. Thanks again, Brett My engine has had compression releases installed since it was originally built. Your adapters (and I love them!) simply allowed me to run acr's instead of mechanical or "push-button" releases. They're all wired in, and work just fine. I really cannot address easier starting, back-firing, or any of those kinds of things since I only really changed the method in which my releases are opened. With that said, I would definitely recommend these adapters to anyone and everyone with a current 10mm push-button adapter installed. They are really slick! I no longer have burnt thumbs or fingers from pushing on the top of a release on a hot engine. Further, and more importantly to me and my feeble old brain, I do not have to try to remember to push the damn things in all the time. Just get on and fire it up and go!! Great product!! The automatic compression release kit I bought works GREAT!! Have a 131 in my bike 600 cca battery and a 1.6 Kw starter still was a pain to start but not any more!!
