Kev's SMT modification list

Post by kevxtx » Sun Mar 17, 2013 2:33 am

:D All started 9/3/2013 on a White 2012 SMT

Image

I am not going to go into each mod in detail if I have already posted the mod in the SMR modification list. viewtopic.php?f=13&t=3299&p=9087#p9087 I will post new mods here that apply directly to the SMT.

List of mods in mind, may not in the order below but will work through them & post the results.
1/ Weight reduction, in progress
2/ Fork height adjustment, done
3/ Bar vibrations, done
4/ Build a custom fuel map for a completely standard SMT, done in map section
5/ Fit my PCV & Auto Tune A/T300, done
6/ Fit Leovince pipes with carbon heat shields, in progress parts ordered
7/ Fit my DNA stage 3 air box, in progress
8/ Remove second flies, in progress
9/ Fitted my STM slipper clutch, fitted at 1000kms done
10/ Get some colour on to the bike, anyone spot my white carbon side covers? Cover now gone for painting
11/ Fit my second fan conversion, Done
12/ Running a 42T rear wheel sprocket at the moment, ordered in a 43T to test. The reason I have gone for the bigger rear sprocket is to stop chain slap below 3000rpm & to reduce the bikes wheel base.
13/ RC8 320mm front brake rotors conversion, rotors here waiting on bolts.
14/ Super Moto head light conversion using a 2013 200 Super Duke head light

Hope have all that done in the next week or two.

1/ First mod had to be a weight thing, coming from the modified 990 SMR I could feel the difference between straight away.

Weight differences between my standard STM & my modified SMR.

2012 standard SMT = 105.3kgs on the front wheel fully fuelled. Verse my 2010 SMR was 97.2kgs fully fuelled, after weight reduction.
2012 standard SMT = 103.5kgs on the rear wheel fully fuelled. Verse my 2010 SMR was 96.6kgs fully fuelled, after weight reduction.

So the standard 2012 SMT is 15kgs heavier than my modified SMR when both are fully fuelled, now I know why my SMR felt so nimble, I am busy working out what weight I can get off the SMT, should easily get off +12kgs.

I started off removing & weighing items to see what I can get off, the battery was my first choice as I have a Shoria lithium iron battery to throw into the SMT.
Standard battery with rubber carrier

As I never lift removing the rear pegs would save me.
Image

One metal heat shield weighs.
Image

The 4 tie strap brackets.
Image

The 2 heat shields + tie brackets + rear pegs combined will save.
Image

When I get the SMR rear exhaust hangers + rails with carbon cover I will get some more weight off, I will up date this post as weight comes off.

So far 5511kgs off, I know my Leovince pipes will remove a further 4.5kgs off the bike, I have set myself a target of 12 + kgs weight loss.

These also arrived from Germany yesterday my SMR carbon exhaust heat shields, beats the 2.5kgs of SMT heat shields & brackets.

Image

The weight saving when fitting the STM slipper clutch.

Image
Image

Complete standard air box weight.
Image

DNA MK3 air box weight.
Image

2nd flies + shafts removed.
Image

SAS system removed.
Image

The SMT complete head light weight, I was surprised how light it was.
Image

My new 43T rear sprocket arrived today save a bit of weight, also forgot to weight my hand guards.

New 43T
Image

Old 42T
Image

Hand guards
Image

Weight results
Battery = 2966g
Rear pegs
Heat shields = 2545g
Clutch = 387g
Air box DNA = 970g
2nd flies + shafts + motor = 336g
SAS system with valve = 510g
Rear sprocket = 489g
hand guards = 481g
Leo Cans after repacking = 5000g

Total savings so far = 13684g :D The weight saving is almost the same as running full tank of fuel compared to an empty fuel tank of fuel.

I still have to weight the head light I fitted.

SMT front end handling.
I have found the SMT does not turn in as well as the SMR, the SMR's steering is much quicker mostly due to the SMT weighing 7kgs heavier in the front end. I did find raising the forks through the triple clamps from 3mm to 10mm helped the steering a lot.

Note: I have since set my forks to 5mm as I found in the bumpy fast tight stuff the bike was under steering.

Before @ 3mm
Image

After set to 10mm
Image

Lift the bike slightly to take the load off the forks & adjust one fork at a time, loosen off the top & bottom triple clamp bolts then twist the fork up to 10mm.

Bar Vibrations
After riding the SMT around for the past 600kms I find there is a vibration through the bars around 4500rpm which the SMR did not suffer from, so I checked to see what was inside the SMT bars, nothing to stop vibrations, The SMR has long brass rods + end bar weights to reduce bar vibration.

Having been around single cylinder bikes for a while & they suffer from bar vibrations, so I have a mod lying around ready to fit to solve the problem on my SMT. The brass weight is suspended in the middle of the bar & acts like a whip with the vibration been transferred to the end of the bar & back down the centre of the brass weight, helicopters use this principle on their motors to reduce vibration. I have different weight & length brass bars I will test each one & find a length & weight that suits the SMT vibration & report back.

Repacking my pipes.
I decided to open my Leovince pipes after 13000kms to check the packing, as I run cats in the cans which generate a lot more heat than free flow pipes.

I was very surprised how well the packing had lasted 13000kms, it did not really need to be renewed but since I have opened the can up I will renew the packing.

I have ordered in new packing so I will show how to repack a pipe.

I fitted my PCV & PCV to the SMT today. Let the mapping begin.

This is the A.F ratio at idle when warm on my completely STD SMT.

I had to remove my front pipe so I could cut the holes bigger to fit the bigger Wideband Auto Tune O2 sensors, I cut approx. 1mm out of the hole.

Thanks Dave, finished a PCV completely STD remap on the SMT, start a Tune ECU STD remap tomorrow, then on to a Tune ECU performance STD map as requested.

These also arrived from Germany yesterday my SMR carbon exhaust heat shields, beats the 2.5kgs of SMT heat shields.

Have you got a picture with the complete bike with the rear white panels? I've got the paint to do mine and going to get smr style decals made

I will post some photo's for you tonight all ready at work Thursday 7am here in Oz at the moment. I used carbon white vinyal to see what it would look before painting the side covers, you are the only person to notice the colour change. I will get them painted soon as I like the colour change to the back.

The SM exhaust hangers from the UK $35.00 used, the SMR carbon shields from Germany used but look brand new $130.00, 2 SMR side rails waiting on KTM Australia for delivery $20.00.

I will post up all part numbers & photos with before & after shoots when the rails arrive from KTM Australia.

I did find a second set of carbon SMR covers I will see if it is still on Ebay Germany no one was bidding, just cheked it's gone, there is this one that might polish up.

Great picks Kev, I removed the hand guards and replaced them with bar ends with vibrations eliminators as well. Be interesting to see if this take a bit of weight off the front. I did it more because like like the look better but I am sure this would shave off a bit albeit not a great amount though.

Great to see the weight saving by removing the heat shields. I was keen on this a while back but went off it as the boys in blue were a bit active over the pre-Christmas period and didn't want to expose the cans too much for fear of unwanted attention. But they seem to have reduced their activity at the moment so it may be good to revisit.

I reckon forged wheels would save a few kgs but it is an expensive way to go. I did look into it but not much money back out of a few thousand dollars to save a few kgs.

I would go there is I was going to keep the SMT long term.
