Maintenance, Servicing, and Mechanical issues / Re: Seafoam

According to the MDS,  this product is mostly naphtha :
     ( see page 2 ).   

So this product isn't much different as home-brew "Seafoam".  But the home-brew "Seafoam" contains some iso-alchohol to mitigate any moisture in the system.  I buy the naphtha at my local hardware store, BTW.

It's called the decoupler and practically all 1215 triples get that knack-knack-knack noise when first started up.  Both of my Trophys (Trophies?) did that.

 I guess that's good to know, but a little worrisome.

In Michigan, the label on the gas pumps say "May contain up to 10% ethanol".  During the winter months the gas contains no ethanol because if it did, there could be a separation problem due to the lower temps.

Premium usually contains no ethanol and in the warmer months.  Mid-grade contains about only half of the amount as regular since mid-grade is a blend of regular & premium - blended at the pump.

I like to run some home-brew "Seafoam"  occasionally just for the heck of it, maybe twice a season.  I don't think it can hurt and probably helps clean up the injectors although most gas today also contains cleaning additives.

See :

If the Tool shows "Balanced" then no adjustment is necessary.  I know that's not very helpful.

When you re-installed the gas tank,  did you make sure the fuel line had a nice wide bend and wasn't almost kinked ?

The first time I re-installed my gas tank, I think I may have had a similar problem with the bike stalling after warming up because the fuel line was kinked.    When the bike warmed up, so did the fuel line and that allowed the fuel line to kink even more and the bike stalled.  After I de-kinked the fuel line, the problem cleared.

I don't like the 180 degree bend the fuel line has to make when installed.   I'm planning on making up a 180 degree bend using brass fittings and installing that some day to replaced the bend in the fuel line.  But that would require two additional crimp fittings that potentially could leak - but I think it would be an improvement.

It gets a little tricky because as the adjustment(s) are made and the idle speed changes, the computer will adjust the idle speed up or down to keep the idle speed set proper.   Like Digital said : make small adjustments and have some patience.

As I posted awhile back,  I used an old VW style flowmeter to measure the actual flow and make the adjustments.  The software seemed to make the adjustment process more complicated as it should ( IMO ) because the computer is constantly adjusting idle speed as the adjustment for each cylinder is being made.

When I finished, the software ( Tiger Tool ) said I was "balanced" and matched within 1 KPa.  Two cylinders were the same and one was 1 KPa different - good enough for government work.

I also think it's a good idea before the adjustment is made to check for leaks by placing a palm over each throttle body opening  ( with the engine running of course )  one at a time.  You should feel a nice vacuum at each and the motor should stall if you keep you palm on each throttle body opening too long.  If you can't feel a nice vacuum and the engine keeps running with your palm occluding a throttle body opening,  then there is an air leak at that cylinder.

Does the noise also disappear when the clutch is pulled in all the way ?

If yes,  then  I understand  this noise is not uncommon.  My Ď15 does this and a friend of mine with a Ď13 Explorer XT with the same engine / trans also has it.  He bought  the bike new and now it has over 50K miles on it and the noise hasnít gotten any louder.   He thinks the noise is caused by the trans gears bouncing back and forth a bit on the  gear shaft (s) when in neutral.

Iím not too concerned.  The trans shifts great up & down.

I had read about that possible remedy when I was trying to free up the caliper pin that was stuck. Now that I have a functioning, and properly lubricated rear brake caliper, I decided there was no sense throwing good money after bad on the old one. It's now resting in peace in a landfill somewhere, gone and soon to be forgotten.  :164:

How sad   .....   I wanted the satisfaction of helping you out with that tip.

Did you check the pins on the front 2 calipers ??


Digital :  Good reminder when welding on the bike without removing the part first !!!
