The Jury is still out on the performance of carburettor vs Fuel injection. Sure EFI can get emissions down ( which is the biggest aim of modern engines ) and is more convenient because no pesky choke to worry about. RR had looked at fuel injection for Merlin before the war and decided that carburettor had advantages over fuel injection because the way the carb works uses the fuel to cool ( by evaporation ) the charge going into cylinder, which means that it expands more when the charge gets ignited. Remember that for comparable power output the Merlin was only 27 litres and the German DB engine in the Me109 was 36 litres, the extra capacity arguably needed to replace power loss due to Fuel injection, The RR Merlin turned into the Griffon which IIRC was fuel injected. But for capacity the Merlin with carb punched well above its weight - helped by higher octane fuel than the Germans had. https://www.griffonmerlin.com/2010/0...uel-injection/

Certainly once I had "messed with" my 390 Duke (by fitting a Powertronic Piggyback ECU and freer flowing air filter) it hugely boosted the mid range torque (where it ran pretty lean as stock for noise / emissions considerations I believe) and it never really felt like I was thrashing it. I remember thinking that if it had felt that good straight out of the showroom it could have harmed sales of the much more expensive 690, as people would have seen much less need to upgrade. However much or little more actual perfomance a 390 duke can claim over a stock DRZ, I'm confident it would certainly feel faster in a straight line due to you being sat about 4 or 5 inches closer to the ground. I'm not the only one to consider that the little KTM evokes some of the spirit of the RD350LC, by being a small light bike capable of (at least) giving the impression of a surprising turn of speed, something that even a tuned DRZ is probably less likely to do on account of it not really being small in the same sense (it's that seat height again) even though it is indeed light. Whereas the 390 duke has a 125 road bike chassis, a supermoto is a somewhat different animal (I should know, as that's my other KTM ). Certainly for me these days, I feel it is the sensation of speed just as much as actual speed that tends to help in making motorcycling a fun pursuit and a 390 Duke really delivers in that area (on the right roads). Anyway, all that said things have moved on for me since I first commented on this thread........ Quote:
I've put the SV on the above diet as promised, ridden it for 250 miles and yeah, I can't really fault it - it's pretty great !

I rarely, very rarely went on 70mph roads on DRZ, that is not what a bike like that is for - on B roads ( and there are plenty of those in Shropshire ) it handled like a dream and had an unburstable engine - I often wish I had kept it as well as getting SV I have now, but never been a bike collector, and the very high seat bothered me. The main problem on 70mph roads was really that it needed a 6th gear, i was not the only DRZ owner who kept trying to 'change up a gear ' when in 5th.

Re: The SV
16 years since I last rode it, but I seem to remember having the exact same issue on my DR350. On the more potent DRZ, perhaps it could have been worth experimenting with slightly taller gearing? Still I guess buying the SV comprehensively solved the issue

Re: The SV
I got my new K3 SV650S the day I passed my test (I was a late starter at 35!). It was a bargain and looked great in blue. The Remus can used to echo off the building in London and I loved the back end, tail tidy and Ermax undertray with intergrated indicators. Did my first track day on it after riding for 7 months at Brands Indy and shocked people weren't passing me with their SS600s and 748s. The Ohlins suspension and brake upgrades might have helped though .
As the first year of the pointy, I used to get stopped and asked about it all the time. It was a great bike. If it hadn't had bit the end of my thumb off when I was stupidly cleaning the chain with it running (yes, we all know not to do that now) I might have kept it but it had to learn its lesson! I get stopped now on the Bonneville by the slightly greyer crowd (me being one of them) who like to reminisce their youth. Not the same!! The SV will always be special to me but my GSXR600 K2 will be my favourite purely as the best track memories were on it, quite a few with people off this forum, Weazel, Luke Miller, 30MPHMax, ROB_SV, Dicky Ticker (came to watch, lovely lovely man), Blue_SV650 (he was super quick, fast group at Silverstone!) and quite a few more I can't remember now. Good times

Blue-SV650 , I forget his name , was he the bloke that whizzed about with a fag on the go in his flip front lid, scraping his pegs? He was fast, he poss lowsided on a rideout onetime. Blast from the past

The Blue I remembered did some track videos. He also did a very funny get your knee down vid using a model bike and a doll. Unfortunately some members Took offence at his commented and humour and got him banned. He was seriously quick. Think he was from Portsmouth way

Re: The SV
Feel free I have met quite a few people that have done similar since. One guy lost his middle 3 fingers as had grabbed the chain Had a thumb brake installed
