  5. Painting engine question

    Projects and Builds
    I had an accident last month and since I'm having to replace a few things (rip Vance and Hines pipe) I decided that this is the perfect time to paint the engine. I'm basically doing a complete tear down and re-painting/polishing everything down to the last bolt. So that brings me to the engine...

  9. Is this a common mod on engine block?

    Engine / Exhaust / Cooling
    First post! Just got a 99' vulcan 750 from a friend for $1000. My first bike! He included the helmet. So the bike starts up ok. I was having a hard time getting it over 4000rpms but I think I solved that issue too with some carb cleaner. It seems to ride pretty well too. I was inspecting the...

    Hey all, First off, if this is in the wrong place, let me know and I'll repost it. I'm parting out an engine that has no compression. The PO tried getting the clutch basket off and busted it all up so the bottom half is still in one piece. I'm selling the top end and all parts included in...

    Engine / Exhaust / Cooling
    Okay so I am shopping for a new starter for my bike. I recently got it built (I got it as a box of parts and a frame) and I attempted to start it and it would roll over a few times (difficultly) and then stop like it had a dead battery. So I put a brand new battery in it and it is still doing...

  16. Vulcan Project

    Projects and Builds
    I picked up an 86 vn750 earlier in the year, rode it most of the season and fell in love with it. Unfortunately the stator went, so I figured since I had to pull the motor anyway id go through the bike and restore it/clean it up. Engine runs beautiful other than the factory cam chain tensioners...
