Tarwetijgers Winter Works

In my opinion, don't treat it too gently or you'll end up with glazed bores and oil consumption. Short bursts of acceleration (but not full load) initially then build up the load to bed the rings in.

Well, it may be subconsciously, but that is exactly what I have been doing!
Will continue to do so.

BTW, the engine warms up insanely fast. Like, in minutes. Would it be wise to put in a bigger main pilot, just to be sure? I have #165 now, but have #180 laying around. Mikuni TDMR40's.

When i had 878 i just would not go into town with red lights & traffic. Got up to fan starting temp really quick.
I think you had samco´s? That lowered my temp in 900 engine a bit.
Go dyno it to spot on instead of guessing

[Tarwetijger]

Of course it will go on the dyno but not before riding in is done!
What I meant, during riding in it is better to have it too rich than too lean, right?

Yes I have Samco hoses.

I was at a 170 main on FCR´s with the 878, mech guy went down on the 900.
And weather/temp should be somewhat same....if it helps....Sockfilter!

After some messing around with the banjo bolts, the oil light doesn't flicker anymore, hooray!
The bolts I used had bigger holes and had the holes on two sides. The original ones has smaller holes and only at one side. Apperently, this makes a significant difference
Thanks Theo for the warning!

Killerwhale, do you mean a ramair foam airfilter? Already have that fitted, I don't like to get everything from bugs to sand get into the engine.

Yes, ramair sockfilter....keeps the small birds out!

[Tarwetijger]

Yes, ramair sockfilter....keeps the small birds out!

But what about big birds?

The temp doesn't get beyond 70 if I keep driving, so maybe it is not that bad.

Mine read 65, but went WAY hot if traffic & lights...

2 bar cold, >1 warmed up. While driving normally is goes easily to 3 bar and beyond.
So, nothing wrong at all. The 20W50 oil I ordered, will be delivered today.

You'll need to go and buy a classic car for the oil now

hmm interesting idea, which one will I chose?


Nah I think it is better to send it back (advantage of buying online: you get the time to change your mind, by law!).

Today was an important day: On the Dyno!



Blue line is from a couple of years ago, Mikuni TDMR flatslides with bellmouths and Akra headers, standard engine.
It was a tad rich back then, I fitted a smaller main jet but never made it back to the dyno. The bike ran very smooth though.
Green line is from today, also TDMR and Akra of course but also: Carrillo conrods, JE pistons, Sanddune valves, ported head, Kent cams and TCIP4 Ignitech unit. I removed the dB-killer for the run.
I also saw 98,99 bhp on the screen but for some reason this value didn't make it to the printed graph.

I am very happy with this result! But it got even better. I had to fuel it up on the way back to home. It did 22 km/ltr (51,7 mpg) and that is including the dynorun! I love this bike!

Excellent Robert,
You must be a proud man.
I bet it pulls like a train now and with the Marvic's on you'll be leaving a lot of guys pulling their hair out on how to catch you on trackdays ..

[Tarwetijger]

Yes it runs great Cobba.
Too bad there was no time left to get another run with the original ignition, so we finally had a back-to-back comparison between original and Ignitech.
