hey all! so i just purchased a 1981 xs650. the bike has 13000 miles on it and the engine has not been started in over 15 years so as you can imagine it doesn't make a sound. my end goal in all this is to make the bike have a frisco style with a few other styling queues from my favorite parts of all different styles. with that comes my first issues. turning this bike into a hardtail. ive seen a lot of different ways to do this from universal mounts to just doing it myself to modifying. im not very proficient at welding but could probably get a welder and have it done. what are suggestions for this? also the engine. considering it hasn't been run in about 15 years i can just imagine all the gunk that is built up. from all of yours experience after cleaning the carbs and engine out, replacing gaskets and lines will this engine be worth saving? please respond with any and all suggestions, pointers, etc. so i can get this bike running and looking beautiful!
