So installed a 86xt600 carb on my 85tt600...... Thx for all the Info everyone. The bike starts right up now, idles great, performs awesome. After installing the carb I realized I needed a new throttle (twist/pull) type so I got that. Like I said the carb worked wonders with no instalation or performance hiccups. I even located the stock airbox for it. Ebay, Craigslist, and my local part store I've pretty much found everything I need and continue to need. My new prob is I've got 2 oil leaks one will be fixed today which is a relatively easy fix. The other is the threads on one of my oil filter screws (case side) are stripped and gone completely. So I've filled the hole with jbweld and its been curing all week I will drill and tap it tomorrow. (Helicoil did not work) Hopefully it will be as good as it is stock. (Fingers crossed) if not I will have to figure something else out. Like I said the bike runs great and I can't wait to really get out for a day on the trails. I just need to get everything dialed in. I will keep ya posted. Btw Thx for the skid plate info I will invest in one of those after I get all my mech probs out of the way. Thump On Thumpers!!!!
