A few things to check/do * make sure there is no animals living in the airbox make sure your idle is at or around 1200rpm +- 100rpm * start looking for someone in your area that can do a good fuel injection set-up [/list] what do the spark plugs look like? is sounds rich the clicking and hissing is the fuel injectors and the air bypass , when the air bypass screws are out a bunch it can get loud. screwing these in will richen the bike and lower the idle. I would bet that they have been used to get the idle up and that is why they are loud. The techtron will work fine as you have it. I doubt that it will help what you have described. I would do the easy things yourself (new plugs and check air filter) and find someone to set up the fuel injection properly. plan on around 1-2 hours of shop time to set it up. They should also be able to read any codes if there is something wrong. good luck
