Hey all, Last week, I finally picked up my 1985 XT600 (49L, manufacturing date of 12/'84) - I bought it from a fellow mid-20's rider. The bike had been in his family for well over 10 years, and he actually learned on the bike. I had some hiccups registering this expired/out-of-state bike, but I'm happy to say that it's finally registered in California! bier With 15.5k miles or so on the odometer, she's in surprisingly decent shape for a 30 year old motorcycle; the seat is the only area that looks terrible. I am surprisingly excited about my XT600, especially having just sold my street bike ('09 Monster 696) - I am loving this bike on San Francisco's bumpy roads. However, due to a wrist injury and not being able to ride for the next 5-6 weeks, I have decided to work on rebuilding the motor as well as improving areas that could use them. Please provide your advice on the following areas that I want to improve, I've spent at least 10-15 hours reading but I still have much to learn, since most of the mods apply to the later XT's: Rebuilding motor to "freshen" things up Front-end swap (w/ different bike) VS stock fork rebuild + springs, oil, emulators. The front-end conversion to a more modern bike will give me more options, in case I want to run Supermoto wheels (eventually?). Mainly, it would let me run better brakes and improve adjustability and stiffness. I want to consider the swap vs overhauling and replacing parts on my current fork, if I'll end up spending the same amount. Rear shock upgrades? Seems a bit soft, even for me 170lb/77kg rider. I read about Ohlins, Wilbers, and Works shocks - but it seems that my model might not be compatible with all. Front brake upgrade - San Francisco is a dangerous place to ride, need to be able to stop QUICK. The newer XT can take the larger rotors and caliper adapter, but my 49L has no upgrade options besides new sintered pads, SS lines, and good fluid. Before dumping money into improving my current fork and brakes - I want to consider the front-end swap; since I have a feeling the costs might be similar and I might potentially end up being unhappy with the current system. Having and sharing some tools with friends, I also bought: Clymer XT600 manual K&N Oil Filters (x4) Yamaha OEM Cam Timing Chain Full stainless steel bolt replacement set Full gasket set (made by "Athena") XT200 wide rider footpegs Adjustable "shorty" levers (somewhat small hands) Here are things I would like to add, but it's not a priority: Clarke or Acerbis large tank Replace or fix speedo/tach Reupholster or replace seat cover Newer handlebars + controls (the old controls feel cheap) New exhaust, or custom setup (will avoid if it actually makes less power) Finally, thanks so much for reading. For most of the repairs and mods, my friend(s) and I will be tackling ourselves. We have most of the tools and have access to a friend's shop after-hours. I'm not necessarily too worried about "labor" since we'll be doing the work, it's more about getting the results I need out of my suspension and brakes and the money I'll be spending on those components (whether it's a new front-end, or parts for my stock suspension).
