Tuning in VM Carburetor - 78 GS1000

[cowboyup3371]

The Carbtune from England is a tad over $100 shipped and will be very easy/useful for a long time to come.

It's up to you, but if your going to keep this bike a long time, I would just buy gauge to sync. and it's pretty easy (especially on VM carbs). For the price of of one sync. at a shop you could pay half the price of the best sync. tool (Morgan), instructions should be in a service manual, or check on Basscliff's site. Also that way you'll know they were done right. terrylee

Ok I may. I keep hoping there is a North Texas member here that would like to go in halvzies or rent them to me. I cant imagine me putting more than 4k on a bike each year, probably less.

Nope -points need proper gap, proper timing and proper advance. -
Put a timing light on it
(i dont know how to do the double quote posting)

Thanks BIG-T, I do think I can find someone around here with a timing light, and I assume I can find the gap settings in my manual.

Greg....Today i had the time to open up the carbs on my 78 1000C. It had been setting for a few months and when i rode it the other day i felt the pipes and number 2 and 3 took a bit longer to start getting some heat...thus prompting me to "refresh them". I took the pilot screws and all the jets out and gave them a good flush of carb spray and repoked all the holes. Gas had been sitting in there and was getting gunky and I knew it.

Anyway, I set the pilot screws ( bottom ones ) at 3/4 turn out and it ran every bit as good as when they were at 1 turn out. This isnt saying thats where your bike is gonna like them, but 3/4 didnt cause any stumbling or lack of throttle response and power. Just thought I would pass this along to you as a "what its worth" info.

Those look pretty cool, I like the dash, and.................. the price!

[chuck hahn]

Theres a hole on each end of the "dash" and you can use a small bungee from each hole to the handle bars to suspend them above the frame where the tank would normally set. I roll up a towel to lay behind them so theres no frame vibrations. I wll PM you some Imageshack pics of them working on one of the bikes.

I just bought a Motion Pro SyncPro that you can use. I live in Fort Worth and am new to the forum. Bought a 1981 GS550T that I just got running, but need the motion pro tool to sync the carbs. Happy to lend it out to you..plus it might be good to see first hand how its actually done!
