So..
Picked up my new bike yesterday.
Terrible timing on my part.
Seattle has been drier then a bone almost all summer and yesterday was hard off and on rain.
Oh well. It's just water right?


Picked up at lunch time and rode the 20 some miles back to work.
Running great. 60 mph freeway type driving most of the way.

Left work and was reminded that I was going to be making my 12 mile commute to the ferry dock through Seahawk game day traffic.
Took an hour stop and go.

Bike seemed ok.

Drive on the ferry and relax.

Time to get off and the bugger doesn't want to start without the choke and then dies unless it you give it throttle.
What the hell I say?

Drive the last 4 miles to home and limp it into the garage.

It's running real rough and kind of ok above 3000 rpm's but not right.

Looked in the gas tank for grins and it looks pretty low me to even though they said they filled it.
I go fill up and it takes 2.25 gallons so it had plenty but IF it was full when I left the dealer and I had like 55 miles on the odometer
that's pretty bad mileage wouldn't you say.
Obviously I don't really know if it was topped off when I left the dealer so that's probably not important.


Anyway I've emailed the salesman and expect Ill hear back soon.
He'll probably just tell me to bring it in which is what I gotta do I guess.

Anyway , brand new to Triumphs so any input appreciated.
I do love this bike though!

I think it sounds like water got in some where ! try some wd40 on the plug caps and a general spray around the carb area might just be damp !

I surely do appreciate the reply and I think you may be on to something but it is Seattle and riding in the rain sometimes is inevitable.
Should be able to do that shouldn't you?

Started it up this this morning and it seemed better but need my truck today so the bike stayed in the garage.
 
You should have no problems riding in the rain but who know when they did the pre sales thing they may have not capped everything back as tight as it should be and some water did get in. It sure sounds like wet something to me.

Not to change the subject but, do you live on Vashon or one of the other gorgeous islands?
 
Did it pop when you tryed to start it? If it did check the intakes between the carbs/fake carbs and head for missing vacuum caps.
 
I had that happen once to me on both of my 03 T100's after riding through a torrential rains. After it dried out, I had no problem with it running. I took apart every electrical connector I could find under the seat, along the frame and behind the side covers. I coated them with dielectric grease and never had another problem. However, I would definitely let the the dealer sort it out.

I hear ya on letting the dealer sort it out BUT if it's as easy as using some dielectric grease and drying things out that's way less of a PITA then the logistics of going to the dealer. (but I certainly will if needed.)
Hell with it.
I'm taking off half a day to go home and tinker and ride.
 
Often times it's relays that get wet and malfunction.

I had this problem in torrential storms. Dielectric grease and encasing the relays inside black balloons bought at a party supply store now keeps those relays dry and trouble free. You can use wire ties to cinch the open end of the black balloons.

I would also recommend you check the map sensor vacuum tubes which are the black tubes around 6mm outer diameter and run from a spigot on the air inlet manifolds to the map sensors under the rear of the tank. Unfortunately the engineers must had a big night before designing this or maybe some wacky tabaky as the tubing is around 4mm inside diameter which suits the Map sensor however the spigot in the manifold is 3.5mm outside diameter so they use a sealant to attempt to take up the 0.5mm difference. I had the same running issues and solved this problem by replacing the complete length of the moulded tubing with equal lengths of 3mm inside diameter vacuum tube which fits correctly on the manifold spigot and is little tight but being rubber fits on the map sensors and no more leaks.

If this is the problem the bike runs extremely poorly below 3000 rpm feels like its running out of fuel splutters and pops. It acutely is the opposite it is running far too rich due to the air inlet leaking on the map sensors they tell the bike the throttle is open further than it is (by less manifold pressure) and to richen the mixture so the EFI is pouring fuel in.

Hope this mod helps all if they find this problem.

One other quirk that has caught a few in heavy rain, and worth a quick check.
I am not sure if the tank on a F.I. bike is vented, but I do know on carbed bikes,occasionally in very wet conditions a drop of water will block the bottom of the vent hose.(This runs from the underside of the tank down past the carbs and stops down by the rear wheel.)
The remedy is to cut the end of the hose at an angle facing rearwards.

Very
interesting.
will certainly keep that in mind.

I read that also on Ratnet and followed that line and it dead ends at the canister with no hose coming out.
 
So I took off the side covers and checked connections.
Went after everything with the air nozzle.

The only thing I found was that one of the spark plugs leads was not pushed on as far as the other.
Don't know if that was it but just got back from riding about 45 miles and she's running pretty good.
a little pop on the down shift sometimes but that's kind of normal isn't it.?
Love the handling!
Love the bike!
thanks to all for the help and advice.
How'd we all manage before the Internet?
