    My GS story.

    Hi Folks.

    I have not posted here for a while, and I would just like to tell the story about my 78 GS750E rebuild and experience, I am in England.

    I rebuilt this bike in 05/06, with the help and advice of the members of this forum. This was a complete every last nut and bolt rebuild, from the bottom up. I retired recently after 50 years in the engine reconditioning industry, so at the time of the rebuild I had access to all the facilities I needed. I found this forum invaluable for specific GS advice and sourcing parts, and I thank the good folks here.

    The engine was completely rebuilt, and I bored it out to 850 using std GS850 pistons. I also did a multiangle valve seat job and a 20 thou (.5mm) head skim. The cam sprockets slotted to keep the std timing. The carbs were rebuilt with repair kits sourced here, and I fitted a Jama original exhaust system. I have always used Valvoline durablend 10/40 semi synth oil, and after 1500 miles it comes out looking and feeling like new.

    I did the usual R/R replacement with the Electrex unit, and fitted the Dyna S ignition and coils. The bike had Hagon progressive fork springs and rear units, and a fork brace was fitted. I also did the 530 rear chain conversion, and fitted a GS1000 rear wheel for the wider tire options. I have used Avon Roadriders since the rebuild and been very happy with them.

    12 years and 26 thousand miles on, I have had no real problems with the bike (touch wood!) Had a couple of frayed clutch cables due to a fault in the lever alignment, but that was sorted. Then the gear display decided to tell me I was in sixth gear all the time when I only have five! Could not find a replacement, so I spliced in a unit found on the net, that fixed that annoying issue.

    I love this bike it is a joy to ride, it pulls well and will accelerate up to an indicated 130 MPH if I am feeling brave!. It handles great and does around 45 to the gallon. People often take a look and tell me they had a GS back in the day and how good they were. Keep up the good work, regards Footy.

                THanks.

                Sounds like the engine should be as good as the bike looks.
