I just put a alukit on my tomos targa lx. I also slapped on a 20mm mikuni carb with air filter and weak ends intake. When I went to reattach my bi-turbo I stripped out the threads in the new cylinder. Obviously I will have to use the heli-coil to rethread this. I still wanted to see if it would start up, I tried kicking it multiple times and it wouldnt start. Is this just do to the lack of back pressure from not having the exhaust on, or something else?
