Hey all, I've just given a Mates bike a full summer service, which included a 4 degree ignition advancer. I've fitted these little things to quite a few bikes over the years and they do make a proper nice difference, cant say if its a bhp increase but defiantly a difference, crisps up the throttle response reet nice

  I read somewhere online that this can be done a K bike, only I cant find the article again. The K is going in the garage tomorrow to fettle up a few things and was going to have a play with the timing.

Does anyone have a link to or experience/advice on doing this?







(P.S. I know it has its dangers so none of the don't do it you fool reply's please folks )

That's the fella, god knows why I couldn't find it

Hi,
Could you let me know how you get on please?
I'd like to do the same to mine.

Mike.

You can quite safely give them 4° more advance, it makes an enormous difference. Factory only set them at 6° to make them meet the smog laws.

Will do Mike.
Rick, which way did you turn it? Looking at it head on. clockwise or anti-clockwise?

Turn the plate clockwise to advance. Turn the plate 2.5mm to get 4°.

Cheers Pal.

I'll report back after I've given it a little tickle

Done did, pictures to follow.
It makes a positive difference, the throttle is nice and crisp. I did the 2.5mm Rick recommended and yeah its worth the little effort it took to do. Then out of curiosity I went a little further just to see. It made the bottom of the rev range, 2000rpm, straight from the get go, very boggy, but get past that and its better, keener to rev higher if you see what I mean. So I tapped it back a little until I was happy with it. Gunna take it for a good run out tomorrow then check the plugs to see how its running.


Worth the effort. Gunna take the allen keys out with Me tomorrow to tweak it. The pictures are on my phone and its taking some time to download to the PC.

Hope this helps folks...

I know this is an old thread, but yesterday I advanced my timing plate 2.5mm clockwise as suggested by Rick G  

Throttle response at the lower end of the rev range is much crisper and seems to rev quicker than before as reported by bettyswollocks.

My bike was smooth at the normal buzz range of between 3800 and 4200 revs before the timing change, and still is smooth so no change there. 

Top end smoothness has not changed either.

Fuel consumption was always good before , but will see if it changes on  a longer trip.

Idle revs have increased by 100 rpm, she now sits at 1k which I prefer.

The motor seems to start a little quicker and the engine noise has reduced slightly, or perhaps its just my perception.

Thanks to Rick G for the info

Now stick a set of K1100 throttlebodies on and get a couple more BHP... and a bit more torque.

...or TB's from a 1200?

Have you tried that one?

Yes, I have a set of them on my Flying Brick. They don't have air bleed screws on them or a fast idle cable because the 12 has servo controlled tickover. I adjusted them with the throttle stop screw and with the engine at running temperature so all's well. I do have to open the throttle slightly to start it and warm it up with gentle blipping of the throttle. It would be possible to fit a fast idle cam and cable but I don't need it on the track bike.

Funny you should mention 1100 throttle bodies, Dai,

 I have a nice set with undisturbed blue paint marks to boot.

Got them from a chap on e bay in Denmark, not too expensive either.

Has everyone who has done this conversion had to adjust the mixture and the response form the air flow meter.

I do not have access to a co meter 

I need to find your thread input Dai, where you swapped the mounting plates over to continue using the k100 throttle cable mounting. 

I have managed to shift two stone in weight, that must be worth a couple of bhp.....

This topic:

My input (such as it was) was from post 95 onwards.

Thanks for the link Dai,

it was your method I was interested in, ie , swapping the throttle body mounting plates so the original accelerator cable arm can be used.

I will probably do it later in the year when I can get access to a co meter for the mixture

Thanks again

Bob
