Ok this bitchy carb has been giving me problems since the get go. At first it would kinda bog down, so i just removed the air box lid then jumped to a 250, it still bogged down and throttle response was horrible. I was scared to go up in size because the plug showed rich. And it had a deep tune, it sounded nothing like a 2 stroke. Plus, it has no power. I cant climb hills. The best gear i have is 2nd. Thats the only one that runs good besides first. Third takes awhile to open up and just forget about 4-6th. So i get home from the dunes today. And i went down to a 230 main and put the air box lid back on. It wont rev to the top cuz it bogs past 1/2 throttle. My bike is completely stock besides my uni air filter and a reed spacer, looks like a 1/2 inch. Any ideas?
