After mounting the Touratech high seat the increased wind blasts made me add a Givi high screen. Now good again.


I have kept the original handlebars but raised them 3 cm, and also tilted them forward a bit. Suits me perfect, both when sitting on the high seat, and when standing (I'm 185 cm. or just a tad over 6 feet). I purchased the Barkbusters, with Storm plastics. I was surprised to experience the uncomfortable high-frequency vibrations through the handlebars, so I added the external Barbuster weights. Helped quite a bit, but not just as comfortable as with the oem bar-end weighs. Another surprise was to experience the increased wind buffeting with the Barkbusters (for me, when combined with the tall screen and the high seat), so I ditched the Barbusters altogether, and life became wonderful again. I have ordered short levers off Ebay, and will rather carry the originals as spares instead of suffering with the Barkbusters (I do acknowledge that most people seem happy with their Busters.)


Another thing. The bike runs soo smoothly, and economically, so I'm reluctant to do anything that could mess things up. But I do feel the temptations to try exchange the original exhaust with an Exan (without touching the fueling) in order to get some crisper throttle response in the lower and mid revs. - Could that disturb the smooth and economical riding I experience now?

Fix Barbusters to the original bar-end weights
 
My last pre-winter ride yesterday.

By the end of the trip - just before going ny the petrol station to fill up the tank for the bike to be stationary through winter - I stoped by the house of a pensioned free-lance engineering parts supplier in my neighbourhood. And yes, he confirmed, can be done in no time: He will drill and thread my oem bar-end weights so I can mount my Barkbusters leaving the original weights on!

Cool! :icon_cheers:

i really advise the O2 eliminator/ controller, that's what made a nice difference.
smoother engine, as a thumper can use some smoothing out sometimes.
if you could try,you'd never go back.

I have actually bought a fine looking MTC exhaust almost two years ago, but did not get around to fit it for the 2017 season.

But i tried for the 2018 season but could not get the header tubes to seperate from the oem exhaust. After a lot of violence i gave up so it still looking damn fine but have not heard it...

There is no room in the frame for heating without taking out the airfilter box but i might give it a go again this winter - and be prepared to destroy the oem exhaust and header pipes in the process ....

Don't think that anybody offers stainless steel downpipes for the xt660z at the moment - otherwise it would be an excuse to just cut if off and go stainless

wouldnt bother with exhaust mod absolutely no gain at no horsepower a couple of kgs in weight the only mod was the seat stock one is really bad swapped it out with this one well worth the money https://www.adventuremoto.com.au/42-...cover-kit-only

The Exan oval classic fitted this spring. :nod:

Oh, and now I too, have come to the conclusion that an adjusted fuel injection probably could improve rideability, particularly at the lower/middle rev range.

Since it seems the bike will stay with me: When budgets allow for it I will add, and get properly dialled, a PC/Autotune.

nikroc 02-07-19 22:18

Like Kev's?

Chev. 02-07-19 22:34

Evidently good value.

But perhaps I will save just a little longer, and go for the solutions that Kev himself describes as the top-shelf solution, a PC well-tuned for the bike. If I'll keep the bike for 20 more year (will be 72 by then!! :wow:) it won't be that much extra per year (or per kilometre).

nikroc 03-07-19 09:18

As in a Power Commander and o2 sensor?..I was lucky.I got a second hand pcv and o2 sensor off ebay..couldnt resist it.
I have run both of Kev's mods and can thoroughly recommend then.
