Took my carbs apart on my 97 bird today as there was a bad smell of fuel on tickover and it is extremely heavy on fuel, jet sizes were 145 for cylinder 1+4 and 150 for 2+3. Are the bigger ones suppose to be on the outside? It has a stock filter and aftermarket downpipes + Remus end cans. needle's are not adjustable. Any recommendations on how to set it? Put the bigger jets on the outside maybe?
