Good to see that your back. Glad you are happy with the build. Job well done!!:cheers

Bet you can never wipe that smile from your face now.:fact

Its going to be hard riding any bike with less than 190hp. Everything else will just seem slow...

Thank you guys. I borrowed my girlfriend's Kawasaki Z750S for a spin and drove like I'm used to do. And its was completely dangerous at overtaking. I mean nothing happens when you twist the throttle!

And it's quite fun at track when I pass all the newer guys with S1000RRs and ZX10Rs on the straights (and in the corners...) and then they ask me in the pit "What the dam* h*ll have you done to your bike?!". I'm just like: "What do you mean? I have got a slipon and a PC." :D

It makes you feel proud when an 11 year older 1K is earning respect from the latest and greatest 1K owners.

EDIT: Interested in the piston gas porting details if it's not a secret. Is blow by an issue with the aftermarket or even OEM pistons from your experience?

What did you end up degreeing the exhaust on. 103 on the intake?

What is the JE FSR piston? Never mind, found it, it's slipper skirt.

It's insane to think that the bike is 11 years old, soon 12 years old. I had a picture of a K3 in the burning copper color on my wall in my room, when I was thirteen back in 2003. And now when I have it, a stock engine isn't good enough :wacko

Due to the larger piston-cylinder clearance, I decided to do that to minimize blow by. No experience, and maybe it would not have been a problem, but when I had the tools and opportunity I went with that.

I went with 107/105, webcam states 103/105 but after some test in the dyno, I came up with that timing without losing any on low and mid revs. It's a real pita too change the timing with the engine still in the frame. I'm glad that I'm done with that.

A little footnote, I weighed my engine today and completely assembled it weight about 50kg. My crank weight is 7,2kg, it's been lightened at APE and the balancer gear is removed.

With that cam timing, you have a lot of overlap so you will have a midrange from hell that pulls all the way to the top as seen from your dyno draph. :fact

Me and my friends have always degreed our motors for overalap, otherwise you will have a sluggish midrange if you have your lobe centers to wide.

Hi Almgren,

Glad you are digging the bike and your riding pic is showing some nice inside moves.

I believe you when you say you are passing S1000RR's ...do you do this without any type of traction control ? Cause those bikes with TC can be just pinned down the straights and won't wheelie. Plus QS and I noticed when I rode one, tighter gear spacing 3rd through 5th.

Even though Bimmer only has between 175-180 HP lol, you are still going to be near peak power to get by, riders being equal. If no TC, How do you manage this (wheelies/wheelspin etc.) or does the superior torque do most of the damage.

thx G

Hi Gixan,

My traction control sits in my wrist...not failsafe though :p

Of course I've different sprockets/gearing when I'm at the track, I also have QS on the bike. Often on the straights I almost have the frontwheel a couple of inches in the air the whole straights. You have to have some sort of throttecontrol with this amount of power. And I think much of the advantage over the S1000RR is that I've 20hp more than the BMW at 6000rpm up to 10000rpm.

I've also raced against S1000RRs and a 2011 ZX10 (they are not limited here as they are in the US) on the street/freeway, and sure, it can be tough to hold down the frontwheel, but I can walk away fairly easy.

Meet a guy with an K3 with only 7500 miles on the odometer. Completely stock....Okey he'd an tankpad on it...That's it. I'd to take some picture with the bikes side by side. Quite fun to actually see the difference between the bikes.

A couple weeks ago I recieved a special gift from Öhlins Suspensions here in Sweden, I live 60 miles from their HQ. It's an titanium shock spring for my Öhlins S46 Shock. I don't see that I need one for the weight reduction, but hey, how many rides around with an titanium spring :biggrin.
Funny thing that I got an comment that I didn't have an Öhlins shock, because the spring wasn't yellow...:biggrin

Man, that orange and black looks good! Very rare......I have never seen one in person.

What's new man?? How's the bike running? Done anything new to the motor since the last time you gave me an update?
