Nick,
I understand.
Call me anytime if you feel you are in over your head.
You have my cell number right?
I'm pretty sure you will find it runs MUCH better with the Supertrapp fixed.

Brad yeah, I think I have your cell in an email somewhere. I think I'm going to be OK, as long as I don't strip any bolts or break anything... When I put rear-sets on my Blast, one of the case bolts sheared off while I was trying to removed it (hex head twisted right off - I was only using a standard 3/8 socket to remove it!) and that sucked big time... I attempted to drill and repair it myself -- I would not attempt to do that again.... lol.
Last night I started the tear down to replace the intake seals. I went slowly and took my time. First I reinstalled the muffler so I could run the bike and depressurize the fuel system. (Sounded great - and seemed to idle smoother - but that may have just been the elf of optimism whispering in my ear.) Then, I removed the fuel tank, pulled the air-box, throttle cables, and fuel injectors. All I have left to do is take off the flange bolts and the whole TB/Manifold assembly should come right out. I'm going to pick up a 1/4" ball end hex driver after work tonight. I was able to get a standard Allen key on the port side flange bolts, but it was awkward and the last thing I want to do is damage or strip on of those, so I'll get the right tool and take my time. I'll need it for the starboard side anyway.
I also removed the clip on the underside of the Throttle body and tried to remove just that 1/2 of the assembly, and for the life of me I couldn't separate the TB from the Manifold! I bought the seals that go on either side of the TB, so I hope I can get it apart once its off the bike; though I doubt there is any leak there.
I noticed the rubber plug on the Cali Evap fitting was there, but seriously cracked. I'll need to replace the cap or eliminate the fitting. I thought about just removing the fitting and threading the appropriate size screw in there and forgetting about it. Haven't got a good look at it yet so still not sure what I'll do.
Also My front isolator has a tear in the front, underside where the rubber seems to have a seam. It is maybe 1/2 inch long and does not go all the way around or through. Should I replace that now, or wait for it fail completely. It doesn't appear to be collapsed yet. It wasn't that big of deal to pull the fuel tank, so I'm leaning toward leaving it for now and waiting for it to get worse. Let me know if that's a bad plan and could cause stress on the tie-bars or something.
Thanks,
Nick |

Replace it now. They cost about $45. and are very easy to replace. Better now then when the washer starts to rub on the frame. |

A cracked rubber plug on the Cali Evap fitting is a likely big contributor to your driveability problem in addition to the leaky intake seals. Good find.
Regardless, I'd suggest not replacing it with another stock rubber plug but rather installing a short length of blocked-off fuel-resistant hose as a simple fix. That should be a longer lasting improvement.

89rs1200 - yeah I know... I just won a parts manual on ebay and when I get it I'll order the part. I'll probably put the bike back together so I can test ride it this weekend, and leave the isolator replacement for a winter project. If I had an isolator laying around, I'd definatly replace it now.
Sparky In all actuality, I think that it is part of the root cause now that I think about when I got the idle to change and where I was spraying the water. But I only expect it to affect the low speed operation, and not the 4.5K RPM hesitation. The hole is right under the butterfly. When the butterfly is closed, there would be extra air bypassing the butterfly. When the butterfly is open however, the affect would be virtually nil.
So, I'm still going to replace the manifold seals while I've got it torn down as I believe they could be responsible for the high RPM gremlin...

Intake seals replaced, Suppertrapp fixed, new 02 Sensor installed, got it all back together - 37 degrees, 30mph wind- time to test ride.
WHOA - It's all there now!
Maybe it was just that cold, dense, dry 37 degree air, but the bike consistantly picked up the front wheel going into 2nd.  No stumble at 4 grand and it pulls much harder. Even with the cold, I rode for a solid hour and a half.
I got on it hard to cross a busy intersection from a stop, and ended up putting on a show for traffic. Must have surprised people to see a bike with big saddle bags carry the front wheel a foot in the air across the intersection. I didn't do it on purpose and it felt like if I hadn't pulled in the clutch it the bike would have back flipped. I'm going to have to be careful with this beast...
Still have that low RPM burble on decel though. I'm thinking there must be a small leak at one of the exhaust port gaskets. I'll replace those next.
I'm very pleased at the moment though...: D |

Nick, That is great, Once one gets these FI tubers de-bugged they are nice running bikes.
A couple ways to check for exhaust leaks is you can cover the exhaust outlet with your hand (have a glove on) while the bike is running, you will hear where it is then. Another is when the bike is stone cold spray some soapy water on the joints you think are leaking then start the bike. Check them before the pipes start to get hot. But I think you will find out that the burble is just normal sound that you get when you have a supertrapp. My X1 has a burble also.

ITs not just a sound - the bike bucks too...
It occurs only while engine braking, and then one cylider will kick, and then engine braking again - so the bike will not coast down smoothly...
Its weird.
THe "kick" comes frequently, maybe every other, or every 3rd cycle. Not sure if it is only on the front or only on the rear cylinder, but it feels like it only happens on one cylinder at a time.

Nick - I went to a Concours rally this weekend in the Catskills and at the last second decided to take the S3T instead of the Connie. Despite the subfreezing temps all weekend we managed about 500+ miles of riding. I can say that the S3T is a phenomenal sport-touring bike. The bike never skipped a beat and is certainly one of the best long distance bikes I own (I may add a taller windscreen though). It still has a bit of the decel bucking, but I concluded that the bike just loves to run at about 3500-4000 RPMS and in that range it is pure candy. I just downshift if I get into the lower RPMS and that avoids all the bucking completely. Another thing I found is to never completely chop the throttle. I always keep a slight pressure on the grip and it seems to help.
I am happy that you got the bike mostly sorted out. |

You are describing My X1 to a tee.
what Johnny says applies. |

 Johnny and Oldog - I've gotten good at riding around the issue too. At this point, I'm willing to accept it as a quirk that is realitively normal. I probably won't be able to completely get over it until I know exactly what is going on and why, though.
Sounds like that Rally was fun Johnny! Did you have a heated vest or any accessories running off the S3?

Nick, I had a long sleeve t-shirt under a fleece vest, under a fleece shirt under my Joe Rocket 3/4 touring jacket which also has a fleece liner. I also had an overstuffed tank bag that provided a little extra wind protection. I had carhart fleece lined jeans and neoprene winter gloves. My fingers got a little cold. No heated gear. |
