Thanks for the replies I have now managed to get the carb off. It has been quite a mission to get it off.
1. I have tried to read up on all the mods and jetting etc but I'm just going round in circles with it all. I opted for the JD jetting kit and am now wondering how to proceed. I am almost at sea level here in the UK and it is currently below 50F temp. The instructions say that you can/may use the blue needle. However, I really don't want to have to strip the whole bike down again to change the needle as soon as it gets a bit warmer.
Can I use the red needle and get away with it all year round. I'm not doing much riding and its not really competition stuff, or would I really benefit from using the blue needle now while it is still colder?
2. I am going to clean the carb tomorrow on the outside before taking it apart and checking the jets. The jets are currently standard though. I don't know whether I should be putting the 48# pilot jet in or whether to keep the standard jet. I know it says that it depends on how many turns the fuel screw needs but again I really don't want to put it back together and find that I need to strip it all down to get to the pilot jet again. Which would you recommend is safer to put in to try with my new JD needle and main?
3. I am in the UK so can't get the ZipTy fuel screw. I have never really done much adjusting of fuel screws and find the issue quite daunting. I can get an RFX fuel screw which seems similar to the ZipTy screw. Is it worth getting one or can you adjust the standard fuel screw while the bike is back together?
