One Year Ownership Report - '08 1200 Sport

<< < (8/9) > >>

Mal Wright:
Its good to read about other 1200 Sport riders appreciating its qualities. I too have a special fondness for this model. I think this bike in particular strikes that harmony of old school tech and good functional design. And I don't mind how it looks with the bikini fairing, a modern version of the original Len Mans if you like. I am 6' 4" and there is a bit of a reach to the bars which is perfect for me. I think this bike suits taller riders in its standard configuration.

And just to back up what Pete was saying about the map from Mark (Beetle), I have applied the map to my 1200 Sport and it has completely solved the pop on decel. Even just under 3000 rpm, my bike will burble rather than pop, and sounds fantastic. If you haven't looked into applying this map then you should.

On Tuesday I'm towing a 1200 Sport 8V off to Wagga so Mark can develop a log-built map for it. Only problem is I've just rollerised it so the map he builds won't be any good for the flat tappet models. Hopefully though I'll have an opportunity to fix that in the next couple of weeks too! :D

While I'm no fan of the looks of the 1200 Sport it is a magnificent mile-muncher in both 4 and 8V forms. I have one customer who is rapidly closing in on 200,000km on his!

PS. For the 2V Sport 12 Molly, Tony and Mark have all put in a heap of work. I know Tony has an openish pipe on his so my guess is what he's running will work with most aftermarket cans sans dBk. Most of Mark's maps are produced for bikes trying to be reasonably quiet fitted with a killer.

You can go with the PCV + Autotune as well. I actually had it on my bike for about 6 months and it did work well with a decent map. It costs a butt load to Dyno and I didn't want to keep doing that if I wanted to switch maps. If you or anyone else wants the PCV modules, I'll sell them cheap.

sono, my bike doesn't pop on decel. You should check in with Molly and get him to review Petes comments about cutting the fuel at low throttle settings. I believe this solves the problem completely.

Also I am running the PCV and autotune and use it to fine tune the fueling in Marks map. Looking at the way Marks map works I am probably undoing his magic a little where the fueling is leaned out at cruise speed / throttle settings. I will need to learn how to apply what information I get from the auto-tune and apply that to the map. That way, once setup then the PCV/autotune could be removed or disabled. Personally I wont be removing it in case I do other changes in future.

I am a bit surprised by your comments on the cost of a dyno tune. One of the neat things about the PCV/autotune is that you dont need to dyno the bike to setup the fueling for modifications to the bike. The autotune will get you pretty close. Which should save you money in the long run.

What's the difference between the 1200 Sport fuel injection which is not cold-blooded as compared to the V7 Special which is cold-blooded? Are there advantages to the cold-blooded fuel injection system used on the V7?

There are no advantages. It's just that one is done slightly better than the other but in the overall scheme of things they are both fairly drac.

There are a host of good reasons why we have emissions regulations, the problem is that because they are applied in a 'Blanket' way with a bias towards 'Mainstream' vehicles making oddballs meet the same standards is sometimes not only difficult but also downright silly! Throw in the fact that stuff like mapping will be done as cheaply as possible with a view to getting the engine to meet the regulations and perform *Acceptably* rather than optimally means that you end up with a real pig's breakfast that may in many ways be both less enjoyable and less efficient but does tick all the right boxes.

Once again we get to the perceived wisdom that all 'Modern Bikes' are mapped up really lean 'To meet emissions', this is unfortunately crap. The base maps are all rich. Why? Because the manufacturers know that the first thing most owners will do is fling an aftermarket, (Freer Breathing  ::)) pipe on it which will in most ranges lean the fueling out. In the closed loop area this doesn't make a lot of difference becaus the narrow band O2 sensor input will crudely trim the fuel back, as long as it isn't too far outside accepted parameters. In the open loop area though it HAS to be richer otherwise you'll end up holing a piston or some such so the maps are rich. What other excuse can there be for a more modern motor with an exceptionally good combustion chamber design getting such lousy fuel economy coupled with less than scintillating performance?

Unfortunately this idea that all the maps are lean has got traction and most, if not all, of the aftermarket tuning options work on the principle that the first thing you do is turn the lambda input off, (Good, of you are planing for optimum performance and fuel economy.) but then throw more fuel at the engine, (Bad! The un-corrected map is already rich, in some places VERY rich!) so you end up with an extremely rich condition. How many people who are running aftermarket mapping systems or add ons say there bikes are really smooth and feel great but drink fuel?

More in a bit, beer beckons!
