Need some help on getting my oil injection cable adjusted right. I did a carb switch to a 40mm roundslide. Problem I am having is at idle and when I have the track off the ground rev it up. When I check the spark plugs they are always wet. It's not gas because I tryed to light it with a lighter . My cable has about one inch free play. I want to no also is more free ply mean more oil and less free play means less oil. Thanks for any info.

Is that the free play when the throttle is held wide open?? Or is that with the throttle at idle position. P.S. you need to take a shim or two out of your secondary. The belt should be flush to the top or close to it.
 
That is with out the throttle open. That's a used belt. I am at the point of belt deflection where if the belt gets tighter the track will start to move. One shim won't hurt this?

Tape your throttle lever wide open, and then check the free play. DO NOT forget to remove the tape before you try to start it.
 
Free play is set in the idle position on a stock SRV. Not WOT

I'm assuming you're using a Vmax540 or Exciter 570 oil cable as I know the SRV cable will not work with a VM roundslide. You should set it to the Vmax specs (which I don't have for you now, my manual is out on loan). That should have you close.

On all cable operated oil injection systems more of the free play as you showed in the first pic equals LESS oil. Less free play equals MORE oil.

Thanks. It's a exciter oil cable. I will try to look up the proper settings. I no the stock cable didn't have a lot of free play. If I remember right 5/8 of a inch . I just want to be safe.

Good reads ops. I made an *** out of... :cool: well, I assumed that the cable free play adjustment was the same as the 570. Sorry for the wrong info Ron. You are probably fairly rich on oil I would guess, judging from what Ops said. If the jetting you are running is from Yamaha Nutz, run it!! He knows his stuff. You cant really read plugs in these current temps. I would leave the jetting as is and do your testing when the temps drop 40 or 50 degrees. Then you will get a better idea if the jetting is correct.
 
Yes I no it's not the right temp out to fine tune it yet. I just can't understand with only one inch of play in the oil cable that so must oil is coming out. Early this summer I cleaned the exchaust pipe by heating it up. I took the pipe off a few days ago and a quater cup oil came out. I am max out on my oil cable. I can't draw the cable (less cable less oil) any more or I will start to pull the slide down from top dead center. I will have to trim the cable end at the throttle end again. Could the dang pump be broken. Sorry so long of a replay.

I am getting confused here. I just talk to the dealer yesterday and they told me less slack in cable more oil you will get. Did they give me the wrong info?

Less slack means you are pulling the oil pump arm sooner and further. The further the oil pump arm is pulled the more oil it will pump.

Look at it and think about it. Makes sense.

It says you're in Lake Barrington IL, not far from me. Don't know what dealer you're talking to but most down in your neck haven't been in biz that long and there are very few that actually were around when these sleds were built. Dealer ignorance is VERY common and most don't have techs that no squat about much of anything. That includes all brands.

PS, I have never done the swap you have done here so I haven't looked into all that may need to be looked into. I do know that pump calibration (internal adjustments) are different on many and the mechanized action of the different cable systems could play into calibration. Are you using an Exciter cable with an SRV pump? or an Exciter pump and cable on an SRV engine? I know they are driven differently but don't know if they drive at the same RPM vs engine speed. If not and you have a mismatched combination that could be why you are getting to much oil (if you really are?).

One thing about Yamaha that is fact is that they build specific components for specific models and interchangeability is not always as simple as if may seem at first glance.

I have a exciter cable. I most often call rich in Lockport at a yamaha dealer but I called one up north from me it's on rt 83 the name isn't coming to me yet. I have blead the system ones I will try again and see what happens.

First, dont worry about the oil in the pipe. The more often you start the sled and not let it warm up, the more oil will accumulate in the pipe because its not getting hot enough to burn off. Secondly, check the part number on the cable I sent you. I may have inadvertantly sent you an Exciter SX cable which I think, may have a shorter pull.
BTW, I still fell like hell. Talking is a chore and my sinus' are so damn plugged up I cant hear anything. lol
