What should idle mixture be on Suzuki GS?
Start the bike, and fine tune the idle mixture on #1. Loosen the locknut between #1 and #2 cylinders, and adjust the vacuum to 11.25 in Hg (28.5 cm Hg) for #1 cylinder. Tighten locknut being careful not to move the set screw.
What should the vacuum be on a Suzuki GS?
Loosen the locknut between #1 and #2 cylinders, and adjust the vacuum to 11.25 in Hg (28.5 cm Hg) for #1 cylinder. Tighten locknut being careful not to move the set screw. Most Suzuki GS 4 cylinder bikes with stock airbox and exhaust draw greater vacuum on the two outboard cylinders vs. the inner two.
How do you repair a Suzuki GS motorcycle?
You may have to remove the covers over the idle screws. Drill each carefully with a small diameter bit, and extract by turning a screw a few turns into the hole you bored, and pop it out with a tug on the screw with a pair of pliers. To ensure that the idle mixture was correct, I used a Colourtune, a sparkplug with a view!
How can I cool my Suzuki GS400?
You may want to have a fan available to help cool the bike while it is stationary. Set the bike on its centerstand. Remove gas tank. Find a means to supply gas to the carburetors while the tank is removed. I set the tank on the rear carrier of my GS1100, or bungeed a small gas can to the rear of the seat on the GS400.
When did the Suzuki gs1000l come out?
In 1979 Suzuki introduced even a custom version of the GS1000E called GS1000L. It had same mechanics as the GS1000G but had high handlebars, stepped seat, leading axle front fork, smaller fuel tank (15 l/ 4.0 US gal) and short cut silencers. 19-inch wheels. The GS1000L was manufactured between 1979 and 1981.
What kind of vacuum does Suzuki GS1000G / GT have?
Last year’s chain-type E-model came equipped with a quartet of 26mm slide-throttle Mikunis; this year the G-model has four 34mm constant-vacuum instruments of the same make. Suzuki indicated the CV carbs allow more freedom in jetting (spelled performance and quicker engine warm-up) without running afoul of emissions regulations.
What’s the difference between the Suzuki GS1000 and GS750?
And they succeeded. The GS1000 was only slightly heavier than its smaller brother, which was quite an achievement. By lengthening the stroke of the (relatively short stroke) GS750 engine from 56,4 to 70 mm the cylinder displacement was enlarged from 748 to 997 cc.
Is the Suzuki gs1000gt a TSCC bike?
Economic considerations were likewise important; the four-valve TSCC technology found on the GS250, 750 and 1100 bikes is expensive; and since the GS1000GT can get strong mid-range punch by other means (displacement and exhaust chamber), a 16-valve top end might be sales-appealing but unnecessary.
How to change cylinder number on Suzuki GS400?
Remove the screws in the balance ports on the carbs. On the GS1100, they were allen bolts; on the GS400: phillips head screws. Install the hose barbs in their place. Note: for twins, replace “cylinder #3” with “right cylinder” and “cylinder #2” with “left cylinder” in the next few paragraphs

How to adjust the vacuum on a Suzuki GS 4?
Loosen the locknut between #1 and #2 cylinders, and adjust the vacuum to 11.25 in Hg (28.5 cm Hg) for #1 cylinder. Tighten locknut being careful not to move the set screw. Most Suzuki GS 4 cylinder bikes with stock airbox and exhaust draw greater vacuum on the two outboard cylinders vs. the inner two. Step 6
What should the idle speed be on a carb?
Start bike, bring to operating temperature. Set idle speed adjusting screw, clockwise to increase rpm, counter-clockwise to decrease rpm. Idle rpm range should be 950 to 1050 rpms. Adjust idle mixture by turning idle mixture screw slowly clockwise until the engine runs poorly. Note position.
What are the symptoms of rich carb settings on a motorcycle?
Rich Reduced Power – It has less power but seems to be OK and runs. Reduced Fuel Mileage – Your using more fuel per cycle so your mileage becomes worse. Rough Idle – Combustion takes a just a bit longer with more fuel and at lower RPM’s the engine can idle rough.
What makes a Mikuni carburetor have a problem?
If the engine is having troubles at low rpm (idle to 1/4 throttle), the pilot system or slide valve is the likely problem. If the engine has problems between 1/4 and 3/4 throttle, the jet needle and needle jet (most likely the jet needle) is likely the problem.
What should idle speed be on Suzuki GS?
Once the idle mixture is correct, set the idle speed to 1200 RPM (or other speed as described in the shop manual) using the adjustment knob located between the airbox and the carburetors. Cylinder #3 should draw about 10 in Hg (24.5 cm Hg). This is your baseline measure.
Why does my Mikuni bst33 idle so long?
If your bike is running a Mikuni BST33 (CV carburetor) and the idle takes too long to drop back down to acceptable RPM after letting off throttle, it is likely that idle mixture and idle RPM are not properly tuned. This is a very common problem with bikes that have been sitting for a period of as little as a few months to a year or more.

What kind of engine does a Suzuki GS 550 have?
With its transverse four-cylinder engine, four carburetors, dual-overhead camshafts, disc brakes and cast wheels, the GS is—to many of today’s motorcyclists—the epitome of what a modern motorcycle should be. To be sure, the 550 has several completely conventional (some would say obsolete) features whose designs pre-date 1969.
What do you need to know about a Suzuki GS motorcycle?
[NOTE: I have no association with Morgan Carbtune, other than being a satisfied customer] The bike must be running reasonably well: Ensure the air filter is clean, or you won’t have adequate air movement. Warm the bike to operating temperature — a short ride should accomplish this.
