I've got a '88 eltigre 440 LC that I'm trying to get tuned right, wondering if anyone can give me a hand. I've read up on tuning mikuni's and understand the theory but I got the motor off ebay and my carbs were set a way out of wack so I'm not sure where to start. The sled has the factory twin pipe exhaust in the stock can. I'm in Orangeville Ontario Canada where are elevation is 1476 ft and I'm usually riding in 0 to -20 celcius. I've got it close I think. It won't idle but I might have to just clean out the pilot jets better for that I'm thinking. It's bogging midrange but it takes off like a bat outta #%* once I get into the throttle. Right now my needles are on the second leanest setting with a spacer washer (so...two and a half?) and I'm not sure what the main jets are, too worn to read the size. Any help would be great. Thanks guys!
