Yes, really; you’re reading a BOTM article on the very first day of the month. The world is in shambles, and here I am actually getting some work done; I don’t know either, it’s not even a joke…
Ask the question; “What is a Streetfighter?” in a group of people that we have been surrounded with over the years, and chances are you kickstart a full-on brawl. Whatever your opinion, there’s no denying the fact how it started out.
Dig out your oldest SF mags and see for yourself; if it’s just Slabbies and Slingshots with 916-seats; you need to go further back, because it didn’t start out that way. Most were chopped up GS’s, GSX’s and some built out of other inferior brands we won’t mention, hardtailed or not but near all of them were very hopped-up Jap 4’s in a modified factory frame.
Actually, they were all pretty close to the ET you see in the 2 pictures above, albeit faster. The bike you see here is owned and build by our friend EFEchop (obviously), Karl, for friends. Bought in 2011 as a mildly modified 750ET, built in spirit of the very first Streetfighters as mentioned earlier, Karl took his time to build it over the years to what it has become.
A bike not just reminiscent of the “proper” ones in the old days, but a bike that can show up the best bikes from way back when, and now, not only for the fact that it actually gets used on the road. Over the course of 9 years of ownership, Karl used a lot of tried and tested ingredients to get the bike to this level, but it takes more than just the right bits to end up with a decent bike. You need to know how to actually put the whole lot together too.
The weedy 750-lump was rightfully changed to a TSCC1135, complete running gear replaced with obligatory Slingshot parts, frontend mated to the headstock with thug yokes, just like it was done all those years ago. Swingarm on the opposite end balanced out with fancy shocks, exhaust routed thought the hole where the monoshock used to live; this bike has everything and makes it work.
Engine fed with a bank of fresh RS36’s, Dyna ignition and coils for a better bang and every other thing you can think of (bar a turbo); it’s been done to this bike. And then, there’s the paint..
Most bikes you see built now have very abstract paintjobs or even wrapped. These days it’s rare to see a bike airbrushed to within an inch of it’s life; it’s almost a forgotten art. More bikes need airbrushing; there I’ve said it. If there was ever a better example to stake my claim, this bike is it.
Btw; he has a few more nice bikes too; priorities and all that..
Anyway, without further ado; congratulations Karl, your Pork Chop is this month’s Bike of the Month.

Ten years ago, when John first rolled up at an OSS gathering on his GS, for me and many others, at the time, his bike fully embodied the true 
I got hold of an old NCK drag motor a few years ago and it has a pretty good crank and gearbox in it. Crank has Katana rods and along with being welded it has straight cut primary drive gear, along with a matched one for the clutch basket. Cases have been lightened and dipped at Ribble Technologies in Preston. So the bottom end is as good as my budget will allow for the moment. I do need a new clutch before it turns a wheel in anger and this will involve having the straight cut fitted. Originally the NCK engine was a 1420 drag engine but on the road or track that sort of capacity would generate too much heat and quickly cook itself.
The cam chain was a weak spot on Yoshimuras race engines and the team did all sorts to try and reduce the extreme wear during races, extra jockey wheels, longer cam chain, shorter tensioner blade, POLISHED cam chain links and manual tensioner were all employed in the hunt for reliability. Most of this development actually went into the first GSXR engine. So all the above mods will be done to this engine.I have had a jockey wheel and plate made but Roger Upperton does a better version which is more like the GSXR version than the one I have. The extra jockey wheel at the back of tthe head is the reason the tensioner blade is shortened.
The head has been checked over and overhauled from scratch. Bigger valves, seats cut to match and a tidy port job will make the gas go in quick and hopefully make it work right.
