Bike run on dynojet

speedmachine · Post by **speedmachine** » Sun Feb 05, 2006 5:48 pm

After discussion on which chip to run I decided to put my on dynojet.

Took bike to dyno-centre.co.uk in Northallerton having took my bike There two years ago, he already had graphs to go off just with Remus exhaust system fitted. The bike maximum power than was 87.14 [hp] the power between 4500revs to 6100 revs was 51.35 [hp].

The first thing I wanted to check was if it was running to rich or too lean.
Quick run, the bike isn't running to rich or to lean it spot on

Next thing, maximum power bit disappointed with 94.87 [hp] butt. It's an improvement interested I read on the forum about starvation of fuel, and that is exactly what's happening to my at high revs.

So if anyone knows of anything to cure this. Please let me know.

The other interesting thing is, I have managed to improve the midrange by 13 brake horse it is now running 64.10 [hp] that is quite good. air duct, I have made is working well

I would like to check on your mods. Stock bike, Remus Y collector and twin? pipe exhaust, inlet manufactured from Lennies air filter elbow and stock mid pipe. Anything else?
Thanks

Have a look at the thread about do i need a chip,you'll see Crucial runs his with a K12 pressure regulator,probably the thing that's saved his S from the same fate as Malc's,although if memory serves me right after Malc put new pistons in he fitted a regulator and had it dyno'd,so it was shoving extra fuel in at the top end,problem being of course it's a blunt instrument and does it at the bottom end as well.

Over the last five years,there's been war and piece written about chips and fueling,and one of the things i've stayed well away from,after Malc's disaster,it's taken Power Commander some time to sort their's out(supposedly) it's the ownly option that gives you complete control over the fueling,how good is it?? we'll find out in the next few weeks!!.

No - I think his inlet is manufactured from STOCK air filter elbow and stock mid pipe.

I think he reckoned that a 'Lennies' was too expensive!

8 - 13 horses from a chopped air intake

That is remarkable

and Remus 2 into 2, BB power chip and O2 sensor disconnected. Maybe the increased flow of air allowed these things to work properly!!

Remus 2 into 2 BB Power chip 02 sensor disconnected k&n air filter, homemade air duct. Which works well

Ordered k12 pressure regulator, arrived today will try fit this weekend
don't know if it's a big job or not, will give it a go apparently feel a lot better to how it is now.

Keep you posted

The pressure regulator lives under the battery carrier, which lives under the ABS pump, which is a pig to bleed if you empty the brake fluid.
I changed my hoses from elastic to steel a little while ago. A good investment was a vacuum bleed unit - M&P I think. I also fitted bleed banjos to flexible/fixed pipes on the headstock.
I also thought that if I ever took the battery carrier out, I would modify it so that it could be more easily removed in the future.
So, non-ABS, about an hours work.
Do let us know of the gains from the pressure regulator, or not!

ANOTHER REASON FOR NOT HAVING ABS.....as if I needed one

The extra fuel stops the piston crowns melting if you're running a lean set up - sounsds like a big gain to me

Unfortunately I have ABS

Looks like I'm going to be busy all week and.

Have you had a chance to proove the benefit of your mods? I am interested to know of any gains from the dificult to install fuel pressure regulator.
It seems the best results are definately from clearing the restrictive in/outlets, including a K&N, or better still the SJ powerfilter (I'M STILL LOOKING FOR ONE!). but what else? Chip or regulator? Here (after suspension and new pads) endeth the cost effective mods.
