ECP Just installed

[kenlacy]

They are only about a 1/4" in diameter - very small - very easy to miss if you weren;t looking for them.

Guys, I am doing the install as well and I am finding that the bellow's are huge. They don't even come close to fitting into the machined slot in the top of the carb! Any tricks, it seemed when I took them apart they were half #*$&@ in/out as it was. It's starting to wear on my thin patients!

If you or anyone else happened to hit the bellows with carb cleaner, they will grow a great deal! Try taking some brake cleaner and thoroughly clean the carb cleaner off. Then carefully blow dry them with a hair dryer being careful to obviously not burn the rubber of the bellows.

I put them in the freezer it will shrink them down too. Dont let them freeze but cool them off a bunch

Just wanted to comment on my tuning...I made an adjustment to the fuel screws from 2.0 to 2.5 turns...just have'nt been able to try it again. Wheres the snow )-: Darren

Thanks boys, I was so pissed when I wrote my previous message and went to the bar. Next day they dryed up and dropped in!

Hmmm. I'm a little confused....

Freddie, your saying those fuel scews will affect the mixture throughout the entire rpm/throttle range?

They are not pilot fuel screws?

I thought they primarily affected the idle mixture.

That is correct...despite the fact that they are called "pilot mixture screws" they will enrichen the entire fuel curve as even in a normal environment, the pilot jet doesn't shut off to turn the needle jet on. Suppose for a moment that you install a richer pilot jet...you will get more fuel to that cylinder, period.

Make sense?

Yes - but I would have thought the amount of fuel flowing through the pilot jet at WOT would be insignificant compared to the main's contribution (of course what I consider insignificant and what a performance tuner considers insignificant could be totally different...).

On my 05 RX-1 I've been tweaking the pilots a little trying to get the idle right. It came from the factory with them set anywhere from 1.5 to 3.0 turns out and always idled on 3 cylinders. Now I have all at 2 turns out except the mag side, which continued to misfire at idle until I turned it 2 1/8 out (I tried 2 3/8 and it sounded a little rich/"blubbery").

Interestingly, it used to rev around 10,400 (last weekend). This weekend, after finally getting the idle right, it was revving at 10,600+.

It's still stock (no ECP kit - yet).

10,600 RPM's is too high for the stock airbox. Although peak is very broad on the 4 strokes, you stand to gain power by revving lower. 9800 to 10,100 and maybe even 10,200 is all you want to rev with the stock airbox. You lose 5.0 HP from 10,000 to 10,600 RPM's.

I think I found the problem. There is a little oil on the clutches. Not enough to notice slippage, but probably enough to make a difference:

And with the stock airbox on...hmmmmmmmmmmmmmmmm.

 

[yamahajunkie]

most likely coming out the slit in the hose.

 

[ReX]

most likely coming out the slit in the hose.

The airbox doesn't have any oil in it and the external breather tube and oil separator are spotless.

It's definitely coming from somewhere around the PTO shaft. I'm hoping it isn't porosity or something.

 

[yamahajunkie]

pull the clutch and check it out. that will be the tell all then. easy job. you got the tool?
