Hi all. I bought a 2015 F3 800 in April, 2021, which was a statutory write off and set up as a track only bike by the guy I bought it from.
Naturally, I wanted to customize the bike to my own taste, and although it had been fitted with some good bits and pieces, ie..Lightech rearsets, HP Corse exhaust, after market clip-on bars, cf front guard and RG crash protection, I wanted to take things up a level. I fitted MWR WSBK air filter, velocity stacks and larger intake tubes, removed the exhaust power valve and added some carbon fiber bling (rear hugger, front sprocket cover and lower chain guard). I booked it in for ECU Studio treatment and dyno tune and that’s when a major engine problem revealed itself. They couldn’t give the F3 it’s final run on the dyno because it started making foreign noises from the motor.
So I brought it home, removed said motor, found an engine builder of good repute here in Brisbane and after pulling it apart he told me it had at some stage been starved of oil and all main and big end bearings were stuffed. I prepaid, and he ordered all the new parts needed, and it took almost five months for the parts to arrive from Italy’s finest, MV Agusta.
During my long frustrating wait, I took the opportunity to respray the trellis chassis, get all the bodywork professionally resprayed using the Rosso F3 as the model. The previous owner’s paint scheme was not what I wanted on my MV. I also got the front and rear suspension rebuilt by an expert here in Brisbane.
Just a matter of three weeks before my engine parts arrived, I happened upon a motorcycle parts importer on eBay selling a 2015 F3 800 engine with only 3165 kms on it! This importer is only 15 mins drive from where I live. I couldn’t believe my luck, so after parting with a King’s ransom, I slotted a near new engine into my F3 chassis, and after a few more weeks of final dyno and other tweaks, I’ve now got the track bike of my desire after a total of fifteen months of frustration, great expense and lots of swearing! A labour of love!
In closing, I’d say I am slightly underwhelmed by 136.5RWBHP and evening more so by 69.4NM of torque. I had hoped for 140+ bhp. However, the engine was imported from Japan where it racked up just over 3000kms on heavily congested roads, so perhaps it’s not even properly run in and after a couple of track days it might free up a couple more ponies. I hope so anyway. But, to hell with the figures, it’s now time for fun.

Great looking bit of kit there!
Can I assume you will now have two engines?
Thanks mate. Yes your assumption is correct. My original engine, when it gets rebuilt, will be a spare.
I also have a 2016 Brutale engine, which I was going to use, but realized after I’d bought it that although the bottom end of all the 800 triples are identical, from the pistons up, there are quite a lot of differences between the F3 and B3, and I don’t have the correct ecu for the Brutale. So I’m selling the B3 engine.

Hi Micky, the bike is looking good. I actually recognise it as I was going to buy the same bike a few months back. I’m Sydney based and the bike was owned by a guy who lived in Marrickville. Shame it had engine issues, from what he told me he only tracked it once or twice. All the best mate.

I wouldnt be worried about the dyno numbers, our Supersport F3 makes 116 hp on one dyno and near 130 on another, a good header pipe system would help also. Please make sure you have the latest type clutch basket fitted, if not you will be sorry. Good luck!

All dynos read differently. Some (like Fast by Ferraci) are notoriously optimistic.
The only way to tell if you have gains on a bike with tuning is with a before (base line) pull followed by pulls at each modification. It is just a number...meaningless unless done with the same machine/gasoline/atmosphere etc..

Thanks mate. I guess I saved you a lot of grief, lol. My engine builder said that the mains and big end bearings showed definite signs of oil starvation. I found out from the wrecker that sold the bike to the dude you mentioned, that the bike did 15,700 kms on the road, and then only about 400kms on track. Then it sat idle for about twelve months before I bought it in April 2021. Anyway, after lots of headaches and thousands of $ later she’s track ready and I will get to ride it for the first time on Tuesday 16th August at Morgan Park at a Champion’s Ride Day.

Thanks Rod.
Just been reading this thread again and I forgot to ask you, do you know what brand of race headers are available for the F3 800 and which you would recommend?
Cheers,
Mick.

F3 headers selection is limited but I’ll inquire if any of them can be install on stock factory plastic. Most headers mfg, claim for race plastic only?
