It's from a comedy show from Harry Enfield about a guy whose catchphrase is: Ya don't wanna do it like that! Ya wanna do it like this!

Hear hear. I've got both, a 2015 4RT and a 1975 Sherpa, and if I had even more money and even less sence (if that's possible) I'd probably also be the owner of a nice heavy pré 65 plonker. There used to be a saying on this side of the canal among motorcyclists in the early 80's: I own a BMW because I like to ride, and a triumph because I like to tinker

I hope "Don's kit" included a couple of heavy springs for the Cortina.

The road legal version, as it's delivered in Europe at least, has an Lambda sensor and thus a regulated catalytic converter, isn't that enough? Of course almost everybody bins both items, along with all the restrictions , the moment they unpack the bike, because it will be used in "race" version. Just like no one uses the unregulated catalytic converter that comes with a GasGas. You still haven't convinced me of a technical reason for not converting to FI, two or four stroke other than costs and/or the lack of legislation.

How about some throttle control? Or did they change to on/off switches, when I wasn't looking? If I have to believe all the horror stories about way to much power, I would have never survived the transition from my 4RT to the GasGas 280 I once owned. I now have a new 4RT, and I like the extra grunt it's got compared to the 250. To each his own and all that jazz.

I'm pretty sure that motorsport commissions and manufacturers had a part in keeping stricter emission rules away from the sport, and so "saved" the carburetor from certain death and with it the two stroke, at least in Europe. It's no coincidence that Honda, Beta, Sherco and even GasGas for a while, came out with a four stroke at around the same time there was talk about stricter emission norms. And I think cost was the main argument.

I know that some of you don't like the comparison to cars, and it's for a good reason, believe I know, but it's useful because cars had to comply much sooner on emission levels and such. I saw what a carburetor looks like when they try to make it as "clean" as fuel injection and I can tell you it doesn't even come close to resemble the simple carbs that are on trials bikes. I think it had more vacuüm hoses and electric cables on it than my euh... vacuüm cleaner for instance. And for those who like a bit more history and knowledge about Honda's "small engine" FI system: http://world.honda.com/motorcycle-technology/pgm-fi/p4.html

The throttle body on my 4RT is made by Keihan but the whole system was mainly developed by Honda in first instance for small engined motorcycles. Most small engines have atomizing injectors for fast and complete combustion. One can barely see the holes in the injector of a 4RT. Reed valves are necessary to prevent air blow back / maximum filling of the cylinder , just like a carburetor bike. My previous 2008 4RT never mist a beat, I did mount the aluminium tank bottom to save some weight and prevent rust in the tank bottom.

Sure, and while you're at it, put some extra wheels on the bike as well. DOH!

A car like that, but he couldn't afford a trailer? Or is the owner just that clever?

Some of the more modern engine managements systems automatically switch over to a "get home" mode in case of problems. By the way, not everyone is capable to mend a bike on the side of the road, even when it's one with a carburetor, points and drum brakes. There always have been problems with technology, even in the iron age (i presume )

Sometimes we do, yes. Because if we would always leave it up to the goodwill of the people, we would be in a right mess.

All kidding aside I think you've made a good point there. The only real reason carburetors are still in use is because the are cheaper, that and a lack of legislation.

I know "the green lobby" makes mistakes, just like everybody else, but "the user" could and does benefit from a better environment. Nostalgia is a great thing, but don't let it cloud your judgement.

I really like the comradery in the sport, it's more a battle with your own, as opposed to other competitors. Most riders are glad to help out with advice when one makes a mistake, or is a bit unsure how to take the next hazard. But sometimes it gets a bit to much like this: https://www.youtube.com/watch?v=Bwk38srACrA

Here's one without the decals on the tank (they also dissolved) Watch out for the tank badge also because it might fall off in time. My RH rear brake is with the original cable. Tried a Venhill cable but it stretched too much.

Nice bike though!

I'm guessing you're from Australia?

I've put the DDM "large" fuel tank from H&D Racing on my new 4RT and the first test was very good, still starts first kick. I did remove the bank angle sensor and replaced the large capacitor with a small one from Mitani, to create some space for the fuel pump. I saved about 660 grams weight, but I only gained about 0,3 to 0,4 liters of fuel capacity as opposed to the claimed 0,5 litre, but every bit helps i suppose.

Normally they don't chrome used parts that are dirty inside. Stick with the very high temp paint.
