15t sprocket,14 tooth sprocket ordered
rexxer flash on hold till end of season because.....

Well, 100 miles on the twisties in Northumberland yesterday, on roads that I know proved to be a bit challenging if not a little scary. the front suspension is pretty agricultural alm ost felt like it was bottoming out but I wasn`t going fast enough. Every bump was a boneshaker
So I need to return comp and reb to stock,wind in the sag and start from there. I note ChrisP`s K Tech upgrade seems to be the way to go but I can't afford that just yet.

When I had the S2R with knackered forks I bought Capo`s originals from his S4 when he upgraded to ohlins (was great to meet him and so sad not to be able to now) and I just wondered if there are any suitable forks from other bikes
that would be suitable

Your experience with the Evo forks is pretty typical. Agricultural is the perfect description. You say you weren't going fast enough to bottom the forks but don't rule it out. The Evo has progressive springs and the first part of the stroke is pretty soft and gets compressed quite easily leaving only a reduced firmer part of the stroke to deal with bigger bumps or hard braking. Try slipping a cable tie round the stantion to see exactly how much travel you're actually using - you might be surprised.

Because of the progressive springs and ineffective damping, it's unlikely that you'll see much improvement simply by adjusting them. I carried out the same K-tech mods as Chris but the lightest springs they could fit were 8.5N/mm and I really wanted 7.5N/mm. I subsequently sent the forks to Maxton, who made a different spring spacer and fitted the 7.5N/mm I wanted.

If you don't want to commit to a full upgrade, you could consider just fitting single rate springs tailored to your weight with different fork oil. Crawsue did this - I sold him my 8.5N/mm springs. I believe he needed to modify the fork tops slightly to accommodate the springs so you could PM him to see what exactly was involved, what it cost and whether it was worth it.

I think I'd recommended tuning your current forks rather than fitting some from another model - even if you pick them up cheap, you're still likely to have to change their springing and damping to suit the Evo.

It's definitely worth the effort though - roads that were 'challenging' on standard springs are now a joy with the uprated suspension.

i found the forks too jarring, everything else about them was fine for me. However that jarring is difficult to deal with on even slightly bumpy roads. So I went the self tune route (done it on my street triple years back so no biggie); my forks feel pretty good now. Although it took about two seasons to dial them to my liking…compared to about a half season on my streety.

thanks I`ll ask him about replacement springs. Funny, I used to replace standard springs with progressives on Bandits and Fazers

Although this won't affect the symptoms you describe, while you're looking at the forks, you could also check the position of the tubes in the yokes. If they've ever been removed, they may not have been replaced at the correct height. This is from the manual:



If you do need to adjust them, the torque is 24Nm for the top yoke and 22Nm for the lower. Apply moly grease and tighten the lower yoke screws 1-2-1.

As Vince says ,I traded up to his K-tech springs, had to do some modest machining of the top caps, obviously did an oil change and noticed quite difference. The re-flash is a given, after that it's sparkly trinkets to bling it up!
But I've enjoyed my 2 summer's of ownership, I've had (and currently have) other stuff....most is a bit faster than the Evo.....but NOTHING is as involving.... Enjoy the ride.

Thanks, is machining of the top caps always required or is it dependant on the rider weight? I don't have access to a lathe but my brother-in-law was a turner and has a lathe so it's not a show stopper. We have a k-tech specialist locally so I may decide to go down that road, depending on how much it costs

DP Air Filter etc.

I've had my forks revalved and resprung by my (sort of ) local Ktech specialist. There were nearer options but KRG seemed the best option having sorted suspension on EVOs before. Couldn't stretch to a Nitron shock but he tried to find components to revalve and respring the shock but unsuccessful, so the shock has had a heavier oil and an Ohlins linear spring fitted. All matched to my weight.

So time to get my ECU to Neil at which point I find I have a DP air filter. So the bike has had both Lambdas removed, plugged and electric connection plugged, exhaust valve removed, carbon termis, DP air filter and top, DP seat all done before I bought the bike. Why? It puzzles me why anyone would upgrade all this and not remap the ECU. I checked the dash and no reference to DP there so I'm wondering if the remap has been done......but if it has why is the bike so bad at closed loop. I'll ring Neil for advice but guess Ill just have to send the ECU to him and hope the remap isn't already there. The ECU shows the following which suggests to me - the novice, that it is a "race" ecu and therefore DP but the dash doesn't confirm this

M1100evoRAC
DOB1U1EOB
Cp.SIL.RAC.
96521511B


The Air filter is dry - was expecting it to be oiled as per K&N, it does look pretty new though.

Finally, is there any point in changing the filter to some other hi flow version?

Filter is fine and does not need oiling, the ECU will be the unit that came with the exhausts and filter, if dash is showing race then it is the DP ECU, and will really benefit from then Rexxerr Flash, also the air filter inlet unit lid will have larger air entry holes to standard. https://www.google.co.uk/url?sa=i&ur...AAAAAdAAAAABAD

Looking forward to hearing your thoughts on the upgraded suspension, Ian, once you manage to get out and about.

Those ECU details you've given confirm that it is the race unit, which is supplied with the carbon Termis and performance air filter kit. It sounds like you're probably just running an unmodified DP ECU, but Neil will know the moment he plugs it in whether or not it already has a Rexxer reflash.

I don't recall my DP filter being wet when new, but it is pink as opposed to the standard one, which is white. There would be nothing to be gained from changing to another hi flow filter unless you fit an MWR but that requires modifying the airbox and probably also a custom remap to suit.

Let us know how you get on.

I thought K&N's should be oiled, the oil is usually red as the pink colour would suggest?

The air filter is stamped Ducati Performance but the element is dark grey with a wire mesh around the filter material. There was some oil residue on the base of the filter which made me wonder if there was a spray you're meant to use. The filter itself seems to be dry so I will leave it as is.

If its a cotton gauze type as it looks to be, it will be more effective if it is periodically cleaned, dried thoroughly and then re-oiled.

Very fine particulates can still pass through the cotton if it dries out and the oil is purposely sticky by design so they will get stuck to it before going into your engine.

Sorry, Ian, I mislead you earlier, my DP filter isn't pink, it is grey as per your photo. (It doesn't require any oiling before use. Any oil you see on the base is probably just recycled oil mist from the crankcase breather.)

No problem Vince, thanks for the reply. I'll ring Neil in the morning and organise the ecu remap.....and hope for some dry (and not too cold) weather soon.
