Carb bowls
after nearly 2 years of sitting in garage my bike wont start, and I didn't winterize it bc I didn't think itd be so long, etc. anyway I changed the gas and dropped in some mystery oil but I don't think its getting to the carb, or thru it anyway. after removing the tank spraying in some starting fluid def gets it going but wont last without it. someone suggested I clean out the bowls.
so ive got the air box off, but cant figure out how to get out the carbs, or even clean them without removal.
any help is clearly definitely appreciated thx in advance

Before you go to far, have you confirmed fuel is reaching the carbs? The vacuum petcock under the tank might have sealed itself shut.
There's a guide to carb removal here: www.vtr1000.org ? View topic - Manual Cam Chain Tensioner Installation Guide (MCCT's)
The only thing holding the carbs to the engine are the rubber isolator boots, these have a clamp top (carb end) and bottom (engine end). Loosen the top clamp off on both carbs (you'll need a long philips head screwdriver) and give the carbs a good heave. You may need to pry upwards on the rear carb to get them started, don't mangle the linkages or hoses.
If you pull off the 2-screw bracket for the throttle cables they can be removed quickly. You will need to very gently thread the choke cable out from under the hoses, once it is unhooked from the frame bracket.
There are two water hoses on the carbs that need to be disconnected, not much liquid will spill.
Stuff rags into the engine intakes so you don't drop tools/screws/debris into the engine.
Hopefully you will now have the carbs in your hands and the real fun can begin...
If you pull the bowls and the jets, keep the parts in separate piles as I understand the front and rear jets may be a little different. If you pull the air bleed screws, count the number of turns to full seated and write it down for each, so you can put them back as they were.
Good luck.
