    2005 MV Augusta F4 1000S shortly to be for sale at AF1

    So in the weirdness of bikes that come to us for service or diagnostics this one arrived from Hawaii last month. Make-run then consign. It was obvious that the VERY common issue of having installed battery backwards was one issue, itís common enough I keep spare diodes in my toolbox. Replaced one relay (same as Ducati 916 item) and two main diodes...fires right up. Oh battery connected correctly too. This early generation of F4 thousands used a system called EBS or Engine Braking System....which is retarded at minimum. What it does is open a massive air valve on the number two cylinder only while over fueling cylinders 2 AND 3. Hence horrific pop and weird vagueness getting back on throttle. Well the bike still wasnít right....on dyno wide open was fine but light throttle was 2 or 3 cylinders running like ass. Another bit of MV oddity is that under 10% throttle they run only on outside cylinders, at idle all 4. So the EBS is a solid state relay, basically a circuit board and a pair of diodes when x-rayed. Hmmmm, more diodes. EBS relay obviously dead.

    Went to local MV dealer, was quoted $375 and 10 to 14 weeks to MAYBE get part. Went on www.mvagusta.net and found a guy in the UK who makes a swap in 27C256 eprom allowing deletion of EBS and full time four cylinder running, full power/logical spark mapping (these things have the dumbest spark mapping Iíve ever seen stock) who for $200 and 1 week transit time. Ordered, installed with a new set of CR9EKB plugs yesterday. Holy shit! The bike may not be cosmetically perfect, but itís running like no other stock-ish MV of its era.

    Soon to be available reasonably priced. On dyno to proof it Tuesday, up for sale Wednesday. If youíre looking for a well sorted, 2,500 mile, 2005 MV F4 1000S model, hit up sales@af1racing ASAP!

    Bike made it through dyno testing on new eprom and EBS delete flawlessly, rides better than 99% of F4 series bikes out there even with full stock pipes, put down equivalent of 159 bhp even through catalyzer. Rides, well, like it should have when it left the factory 14 years ago! If you have always wanted one, this one cleaned up well and will be priced to sell!

    I had an identical bike Micah.

    The EBS is indeed odd. At rest and in neutral it would rev quickly and ran fresh (once fully warmed up, mind you).

    As soon as you'd click it in gear, it went sluggish.

    Merc07 over on the MV forum is a very nice guy from the UK. I had one of his early eproms, but it popped on decal and he hadn't quite figured out how to delete the EBS entirely. I bought an Arrow eprom that I thought would be temporary, but ended up selling the bike before getting one of Merc07's newer eproms.

    Another common issue on these early bikes is that the TPS isn't set right at the factory. I dug around and found the OHM resistance spec and which pins on the ECU to test it from. It was something like 375 milliamps maybe? Anyway, same as an early 996 Ducati I think. That made a huge difference.

    So with stock pipes and mufflers, the cat-delete mid pipe from Arrow, and the Arrow eprom, mine made 161.78 hp.

    159 hp on your dyno is crazy good. That's about 180 on a dynojet!

    John

    *Edit* Reread your post, 'equivalent' to 159 hp, meaning adjusted to Dynojet numbers. Still, that is very good, and it can't be overstated how much better they run from stock once the fueling, timing, and EBS have been sorted!

    Also remembering that Merc07's chip kicks the fans on earlier. That was another silly issue; once the stock eprom does it, the temp is already running off, often showing 220-230 degrees, and this is in the great Northwest on a 60 degree day.

    The stock suspension is awfully stiff, even for me at 190 lbs., but they handle incredibly well. Tight, narrow, planted in high speed sweepers. And that sound. Spin it up to 12,500 revs, like no other bike I've been around.

    Had mine up to about 170 plus a little on my favorite desolate piece of road locally, was running out of that straight stretch and backed off. Effortless.

    Sigh. I'm getting worked up. Maybe I should call you guys. Maybe not. I haven't been riding much the last few years. Still have the RSVR and Guzzi 1200 Sport. I don't need another bike. I'm sure I don't.

    Well you're a lot of help snik.

    I do, I do, and... no, I really shouldn't.

    Damned beautiful piece of work, those. The first ones, '05 and '06, are my favorites. What a design. You can take all the bodywork off the thing, except the front fender, in about 10 minutes. With a glass of scotch in one hand.

    I'm going back to work!

    Ok, I’ve been passing the MV around the shop and letting employees test-rape/ride....nobody has come back with anything less than a GIANT smile

    They are/were great bikes, still a classy design from the late Mr Tamburini by modern day standards.
    40 odd powered two wheelers over 40 odd years. Currently in the garage are a 2016 Tuono V4 1100RR and a '79 Honda CB550F

    My eyes also pricked at the word 'MV'.

    That one looks like a well cared for good example - save for a bit of lacking chain maintenance. I'm sure it won't remain on your shop floor for too long!

    As one with a few 1000cc bikes, I still love my comparably ancient 2007 1000R.

    Just got done riding around one of the bikes I've always lusted after but never had a chance to ride.
    Well, it sure as hell didn't disappoint me and my interest in this bike has grown THAT much more. Definitely a fearsome ride!

    I'm one of the sales guys here at AF1 Racing and i can tell you that it's going to be tough seeing this thing on the showroom floor. No sale price established just yet as we're still waiting on the consignee to come in and get all that sorted. But it'll be worth every penny!
