Hi Made2Care
Great find on the Bike and Donor Frame! By the looks of your 3 completed restores , Like me , you enjoy wrenching as much as you do riding beautiful job on all 3, I noticed on the GL1100 you replaced the 4 carbs with a single VW carb and Manifold, VTC Motors?? I did the same upgrade to my 84 Virago 500 with a Mikuni VM34 , best conversion I did, FYI, VTC motors also has a 4 to 1 Manifold for the Venture along with the VW pict 34 Carb (new).
I just got my 84 Royale Blonde/gold before Christmas, and it came with a complete 84 torndown venture as a parts bike that only has the 2nd gear issue.
I plan on fixing the donor bike to sell to recover some costs.
There is a wealth of info and Experience on this forum I have spent many hours reading thru the tech tips , upgrades & fixes. A big shout out to the many members who contribute on a regular basis to the site Especially Cowpuc for his technical contribution.
Fortunately mine just needs a good Carb overhaul to getting riding this year, the fun will be this fall stripping it down to do a full restore/upgrade.
I will check back on your progress of your rebuild so keep us all updated, Good luck Brother keep it Fun!
