Alright I'm sure your sick of me posting on here so I'm going to go into great detail on my issues and lets see what I can come up with otherwise this things getting trashed! First is my main jets are 144 for all four carbs. I didn't research this subject of cleaning the carbs well enough before I dug into it (Yes like the warning states in carbs 101!) but the first thing Id like to bring up that I noticed now was the pilot jets that were in the bike were already stripped so I Just replaced them all with factory jets (Not knowing this mattered) I just realized I have three that are 32.5 and one that is a 35 (Multiple holes in the 35 were as no holes in the rest). I'm guessing this is the reason after replacing them why I have trouble keeping one carb running after I put the stock back in?
I also have aftermarket 4 to 1 exaust So im guessing a need some kind of jets right?:
Also for the needles Im pretty sure its just stock needles but im not sure, they have no stamp of any sort on them and I dont even know how to distinguish between them!:
Also on the bottom of what bike bandit calls the "Piston valve" is two white screws. Are these meant to be adjusted? because all of them are about flush with hole except one on just one of the valves is screwed in pretty deep.
When I first got the bike it had K & N filters on it. now I got the original air box from eBay and noticed I have holes (the ones you use to sync the carbs) plugged on the diaphragm cover with a hose/screw combination.
This is on carbs 3 & 4. Are they suppose to be hoses that go somewhere? I have the vacuum one that goes to the back of the petcock from the side of carb number 4 and the two fuel down to the carbs for gas and one from the airbox to the crank case. I also have the bottom of the air box plugged. Am I missing any?
Also I'm getting this issue with the spark plugs being black with a sort of black dry film. they said this is from running to rich right? Well im also getting a tad bit of what seems to be a black residue or pile in the lower part of the carbs when I drain them out. Is this due to that same issue or could this be from the tank or somewhere totally different? you can kind of see it in the picture below about were it drains out the drain hole:
Well once I figure this out is the A/F screws 4 screws located on the lower bottom of the carbs that controls the mixture? Or is there two different screws? one for the air and one for the fuel? the one located in the front of the carbs I was told was Air adjustment? Or was I told wrong? Also the more turns out the more air right? So if I'm running to rich Once I have this straighten out if its still to rich I would turn them all more outwards right? The last sort of issue I'm having is there is this sort of glue or maybe silicone type sticky goo that was on the bottom of just one of the carbs.
this sticky goo is also a little bit around the back of the carb as well. I did dip these in chem dip and let them sit but is there a reason this was on there? or somewhat in the carbs? there is kind of a sticky residue on the butterfly valve. Around the area were you see the three small holes there is a bit of a black discoloration that didn't want to come off even after the chem dip. almost looks like a stain.
The main thing though is the one that had all the defects is the one that runs fine.... So im not sure but number one seems to want to only run when you first start it up after you drain the fuel out of the carb and let it fill back up, Sometimes it wont even run at all.. after a shutdown and start-up again it doesn't want to run while the rest seem to run fine. As of now the bike starts up fantastic, sounds great like it runs perfect and idles amazing compaired to when I got the thing When I try to ride it though obviously after switching into first and takeoff it just wants to die. Cylinder one just wont fire and I tell by throwing a cap full of water at the pipes. 2-4 the water sizzles and evaporates right off but 1 doesn't want to do anything! I did check the spark and it was there but it didn't seem to really get the plug black like the rest of them either. There is gas in going into the cylinder but having this different jet pilot will effect this right? Could that be my issue? Any help would be much appreciated!
