[QUOTE="Mihylo33, post: 151995, member: 408"] WHOA! OK... it looks to be a 1990.... I had 2- 89's Now lets start with the basics like mentioned before get a manual ASAP... then proceed to clean the carb from the inside out. watch for harsh cleaners and take your time pulling it apart... This is a Mikuni flatside and very temperamental so be aware of all the gunk inside and miscellaneous parts. once clean, reassemble and use fresh premium gas and a quality premix oil. Lucas makes a premix oil that is cheap and very good. This particular year uses 20:1 mixture for the gas so that's 6oz of oil for every 1gal of gas. Also be sure to check for spark. It should be blue. The bike should start and run after this.... You'll be able to do a topend yourself if you can read and have the proper basic tools. Once disassembled take it to a reputable shop and have them check the cylinder and head for wear and to check the bore size. As a courtesy order your topend kit from there. As for your suspension you'll need to use your manual to check the specifics on what to look for but I recommend taking it to a reputable shop for servicing until you become more wrench ready. I hope this helped and good luck :cheers: [/QUOTE]
