Suzuki GS400 brat custom by Roosters CC

Originally a commissioned build from a customer, the modest budget wasn’t enough to do the build justice, so John of Roosters CC bought the bike and took on the project for himself.
Taking the unfinished Suzuki GS400 project, bought as a box of parts from eBay, it soon evolved into a brat style build. A welcome change from the usual cafe racer and scramblers John usually works on.
Featuring the traditional open rear triangle and flat bench seat look of this style of bike, engine overhaul and neat understated parts fitted throughout, the end result is a clean and classy build that has been turning many heads here at The Bike Shed Shoreditch venue.
Especially when they see the 'bite your hand off' price tag of only £3250.

Just bought a '77 GS400 a few months ago! Can't wait to get it running! Thanks for the video, definitely lots of inspiration!!

Yeah! I made it into a bike shed video, even if it was just walking across the background!

Interesting information about the carb setup.

That mini-tutorial on the velocity stacks was really interesting and helpful. I’m looking at customizing my 91 CB750 and want to keep it simple. So for now, I’m leaning toward keeping the air box, and this just gives me another reason to do so. Thanks! . . . Oh, and that’s a beautiful bike!

[@Ritalie]

I've looked at thousands of cafe racers now, and this is my favorite one. Every detail is absolutely perfectly done, and it looks like a factory bike. Other cafe racers always have a big empty void behind the carburetors. Finally someone recognized that it looks ugly as hell having an empty "void" under the seat. This bike is just spectacular. The colors, the heavy duty chain, the gauges, the seat upholstery, the colors of the engine, and the actual mufflers instead of cheap welded straight pipes. Also, so much for the idea that only frail millenials own cafe racers. This owner, John from Roosters, looks scary as hell.

[@latenite2009]

Two weeks ago, I just bought a 1980 Suzuki GS450S with 2,000 miles for $300.00. It sat in a warehosue since 2004 when it was last registered. There was no spark from one cylinder, Previous owner repclaced one ignition coil, sone park plug , and pulse generator and could not get it started and he parked it since. I diganosed CDI issued and got one used CDI on EBay. Not one trace of rust in gas tank since there was no ethanol ingasoline in 2004. I emoved cabutator and it was cleaned as day 1. The motocycle didd not evn have a chance to get to 3,000 miles for the first oil change recommended by Suzuki, Lucky me. I like carb set up idea, thanks.

[@cedley1969]

Possibly one of the most underrated engines ever made, I had one that had 115000 miles on the clock, still ran fine. Roller bearing crank, fooking strong engine, the later 425, 450, 500 twins had plain bearings,. Those are yamaha RD250 or XS250 wheels and brakes, not original. Edit, XS250 custom, 16 inch back wheel.

[@BritishEnglishJapan]

Agreed! Had two of them back in the mid 90s... brilliant and bombproof! I still have some of the shims from the buckets in my toolbox!

[@connerdouglas7776]

[@lastsonofkrypton36]

So many of the staff bikes look great, and are clearly what people are interested in. Why is it then that there is almost nothing like any of them from the big manufacturers? We want midsize bikes with a simple style. Instead we get giant displacement engines with plastic and fiberglass for days.

[@AndrewBoundy]

Great build. Interesting about the carb vacuum - hadn't really thought of that before, thanks. Only part not 100% for me was the seat fit (maybe 97%) - but that's nitpicking a beautiful build and really, just goes to show me as an asshat.

[@allaboutkalergi5012]

I put Avon Speedmasters on my supermoped back in 1976. Improved the wet roadholding in particular. The original tyres said "nylon" on the side which didn't inspire confidence!

[@panamericaco]

They probably were bias plys, nowadays tires are almost always radial ply. Radials have steel cords inside, bias had nylon. You can tell by checking the size, if it says for example 120/80ZR17 it's radial, if it was something like 120/80-17 it's bias

[@peterroda4181]

Brilliant job!

[@cyclhed]

I would put a mudguard between the seat and swing arm to keep dirt off the engine.

[@jonathonnordyke]

Very nice and clear job , I have a Suzuki gs 400 78” and I try to fix the rejet for the carbylator .. I used k&n air filter ,but not running good ! Can you give me more information about the mainjet ? Thanks for your video . It will help me !!!Nice project .amazing

[@roostersclassiccustommotor4048]

Hi Dom, You need to contact DynoJet and get a stage 2 jet kit from them or a bigger main jet by + 1 or +1.5 from stock. then simply build a chamber from the inlet to the filter that is just slightly longer or that bridges both carbs together and the 2 pod filters attach to that chamber. The bigger distance from the carb to the filter the better it will run.

[@dombarberengineer6471]

[@daveco1270]

Great-looking bike. I like those handle bars a lot, what brand/style are they? I tried one of those Biltwell mirrors on my CB750. It looked amazing but it sat too low and rubbed against the top of my clutch hand which I didn't like. I guess I should've tried it on the throttle side of the bars to see if that was better.

[@leesimpson-o6v]

does anyone know where he got the velocity stacks?

[@lumberjaxx3335]

How did you get the avon 5.0 16“ tire on that 2.15x16“ Rim ? I thought the minimum rim width is 3.0 for this tire

[@jayslaysantuck8190]

What tire setup is it ? I wanted to do a similar tire setup like this but don't know what size to choose

[@desertbeavers992]

Can you tell me about tires size?

[@UncleWally3]

Brilliant build! That truth spoken, why is the tank’s pinch-weld exposed? Why wasn’t it smoothed out, aligning it with early BSA, Matchless, Triumph tanks? Or more generally speaking, what’s the opinion about leaving exposed pinch-welds on tanks?

[@roostersclassiccustommotor4048]

all down to cost buddy. The client didnt have a big budget and wanted an affordable build that worked for him.

[@UncleWally3]

Roosters Classic & Custom Motorcycles. I can totally appreciate that choice with the GS400 build, but why many manufacturers mass producing tanks with exposed pinch-welds is baffling. Relative to the gain in aesthetic refinement, economy of scale ought to attend to their costs. I am glad to see Triumph’s new T120 Scramblers with “clean” tanks and a few other manufacturers seem to attend to their classic/retro models with similar detail. Anyway, I really admire the GS400 build and in the future, I’d be interested in hearing more expert opinions on the plight of the pinch-weld! Thanks.
