Capisce :D

An old clip for you from 2013, its pretty long and its mostly for the people taking action, itll be boring for others, so give me some slack here.
Just to get you a picture of what we do and like. We usually bomb the ice and then go to one of our homes and eat some and watch.
I have two fellas with 570 bikes and were all equally quick so its always a good battle, one is a FE and one is a FS, I hate the FS but the owner is quite good on it, personal preference for you :) https://www.youtube.com/watch?v=ONXPNqZmPKg
Its just frozen lake, cool thing theyve been going there since the 50s, and sometimes the original staff turns up and take there precious down and do heats on them,thyre almost dead now, they dont care, wot!
Tomorrow it will be a more open course.

Youll die watching a proper race then, elbow to elbow it is 16 coming to the same corner, its a lot of elbow fighting. Slight change of track for tomorrow, however one of the fast bikes ive raced against before will attend :)
What most people dont think of is you get hot doing this, at race pace you get silly hot.
I just wear a thin underpant and an oldschhool leather suit with no vents.

I did some research this seams good stuff to cover the hole in the seat!

Now youre expection a vid, sorry, riding got interrupted before I got the gopro on :/

Its not running right and any help is welcome!
Mechanically its ok, starts and idles fine, blipping is ok too.
When riding off in second where you usually pop a litte mono, it bogs and the power isnt there, if I keep woting it runs uneven as in it suddenly gets the power back and then again bogs down, back and forth like that, if that makes any sense?
On location I disconnected the fuel quick-connector and bled what fuel I could get out and clicked it back, when trying it again it now worked for two wheelies and then back to the same pattern.
I remember something about the fuel filtering isnt the best, so any input about known fuel system whoes is much apprciated.

Good news is I got to race the bike I was talking about, a fully tuned 560SMR. That particular bike pulled me on the straight by well over 10 meters last season, now its exactly as quick, not better not worse but equal, and that was my goal, to not be left behind so Im happy with that, now just gotta sort this running issue.

Epic stains were FOC, so was hire of wego unit:cool: Thanks bushmaniac!


Some fuel pump pick up screens were dodgy.

Kinked lines inside the tank?

Build up of oil or water in the 'airbox'? Same symptoms happens to me on big water crossings when a bit of moisture collects in the airbox.

Tillbuilt put his IAT on the outside of the airbox on his snow bike, I'm thinking in that example the ECU sees high IAT (IAT close to motor sees high temp when ambient is low temp) and adjusts to suit, = lean out.?

Bad earth? Ecu see low voltage at high demand?

Bazzazz might be in confict with the virtual acc pump ( I cant turn the f€ckin off with the KTM UST and it ***** me to tears)

Just chuckin it out there. Hope you get it sorted, looking forward to some hectic 570 ice racing :)
 
Thanks for reply Berglsmerg!

I can direct outside air (or warm inside air) into the dyno so I tried it at minus 5 and it compensates very well.

It worked very well for too long to be that, but Ill keep it mind still.

Thanks :)

Edit: I checked the plug cap/boot from a local tip, the lead wasnt loose but the cap itself was a bit dodgy and the plug tip had been worn from it vibrating, new cap on the way.

at about 150 hours I had to replace my cap to.....
Is everything solved or still waiting for parts?
I just ordered myself a seat I wonder it will come with the seat cover or not because the price seems cheap for a complete OEM seat (117€) .
If not I put a black seatcover on it :cool:
 
Just got back home from trying it in the dyno and its back! wooot :D
I had a look at the injector and it looked good, cleaned it anyway, I suspect it was the spark cap, replaced the tip with a fresh one and now it works, but Ill never really know what caused it/what solution was.

The hole in the seat works really well, tried today a couple of pulls with the gutted seat and then tore it off completely, identical result.
A warning is in place, the intake roar takes on another level, I just put ear plugs in.

Probably just because the bike is now working gods decided to dump a massive bit of snow on us tomorrow, questionable if there will be any riding this weekend :furious: Anyhow Im joining the national ice racing series, so there will be some action later I hope.

Is there an instruction on how to perform the seat mod? I have seen photos of the hole in the seat with a little velcro cover, but don't know how to actually do it. What happens if it starts raining... rain goes straight to airfilter (don't know what new models look like, but old one this is the case).
 
That's why I am getting a second seat for days that there is a chance it will rain I use stock seat for trackdays or sunny days seat with hole:cool:
 
Reasonable amounts of water into the engine wont do anything bad, but you dont want it raining in there agreed leaving the bike parked.
While running it can take quite a lot of water, see water injection.
Some folding attraption I beleive I saw too so you can choose open or closed.

I peeked at those pics too and by looking at the seat upside down there is pretty much just one way forward. I used a rotating saw as I was too eager, but you can use a dremel grinder or similar to get a more even cut, my bike is strictly practical so I dont care much about estetics, still looks ok though, Ill have an upholsterer make such a net you mention eventually, for now the bits remaining are just riveted down, looks ok to me but not perfect.

I undid the rivets and undid the canvas, then I drilled it from underneath careful not to penetrate the foam. The foam shape is what determines if it will look good, be careful with that and it will look good in the end imo. The seat plastic is rigid enough to accept this hole no problem, start by getting through the black plastic and then work your way up and make a pretty hole.

I just did it quick now to see if it worked, if I were to do it again Id undo the canvas and then use a marker pen to see where to cut.
