TPS readings?? Keihin or carb conversion 955 Sagem

[metalguru]

the keihin injection does look compact but just comparison measurements are needed. You are nearly there with a 1050 engine swap and if perhaps the donor bike was cheap enough it could be worth while.

Yes I did have a steamer and very happy I was with it as the weather protection is better and once set up would not need tinkering with untill service time, i went to the 855 as a 'progression' but that got written off so here i am with a 955. I wouldn't say I was a perfectionist, just get wound up when it won't do what an engine should!

TPS readings are ok, does it read 74-78% on full throttle?

Is fuel consumption ok on a standard map?

Hassan has poor fuel consumption and he thinks he has overfuelling due to fuel rail pressure being too high - his fuel pressure sensor is not working.

The Fuel Pump Regulator...

Ordered a new pressure regulator and will take about a week to arrive at the stealers. will post the results when it's fitted.

It's interesting that I'd never heard about a problem with the FPR until recently - now they seem to be all over the place.

I said over on Hassan's thread that I'm not sure that's what's wrong with his - he has some pretty fundametal problems to fix first before he goes spending more money.

Going on what has happened to hassan and the wealth of knowledge on here it seemed the logical way forward as even setting the IACV to -10 and LTF tro 4.5 the idle was high and the idle trim went off the scale at minus, it was still rich and lumpy. I managed to rig up a test guage and the fuel pressure is high, perhaps it is a shelf life thing or they get confused with performing maps!
Will get there in the end.
Still investigating the carb thing...just pressed for spare time at the moment.

It's good that you've proved the fuel pressure is high,  :icon_salut if replacing the regulator sorts that ,you'll have validated changing the regulator as a fix, which on-one (as far as I can remember) has done so far.

Once you've got a result, a summary of symptoms and the eventual cure would be helpful

Replaced regulator and validated the change as effective.

Next to start plans for carb conversion kit.
Anyone got some 42mm flatslide Mikunis they don't want?
