Bicycle Mechanics - Triumph Tiger firing on two cylinders at tickover but seems ok at speed

Weird weird weird.

My 1994 Triumph Tiger sounds like it is only running on two cylinders at tick over, but when riding it seems not to be down on power at higher revs.

Now I am either kidding myself, and my triple has turned into a twin - or third cylinder is kicking in at higher revs?

right hand downpipe does not even get warm at tickover whilst other two get hot quickly.(did the water spray test)

I took off the HT lead while it was ticking over and sure enough - no discernable difference

I put a spare plug onto the removed HT lead and spark is very strong...

Sooooo then - clues?

Could this be a carb problem?

Any ideas what I can do next?

hey dude, this is a bicycle forum, you may want to try a place for motorcycles.

if you have spark, then it has to be fuel. check that carb.

At idle, spray a shot of wd40 or starter fluid into the suspect carb. If you get a momentary increase in rpm, its the carb. Start with troubleshooting the idle circuit including float, then synch all carbs.

Check the compression on the dead cylinder. low compression may not idle but operate at high rpm.

...

Low speed juet plugged, or partially plugged. Try a half can of Seafoam, or a bottle of Chevron Techron Concentrate in the tank.

If not completely plugged, that should clear it. If not, excise the clog, while rebuilding the carbs.

Just remember to make sure it gets a lot of time idling while that stuff is in there.

Take a look at some of the ads on the side, then take a ganter down the rest of the forum. Man we sure talk a lot of lame motorcycles here.

Ok Dobber, wtf?

It's the carb idle circuit on that dead cylinder. Try a gasoline applied carb cleaner. If that doesn't solve the problem, the carb will need to be overhauled. Hope this helps.

Triumph Tigers are nice bikes but this forum is for bicycles. Cheers!

o - I think that was supposed to be a "wtf" error message to match the "wtf" OP. Of course, given all the helpful responses to the OP, I'm sure this forum will now start scoring high in motorcycle-problem Google searches. :)

Ok Dobber, wtf?

I figured, what the heck.

How refreshing to have a thread that is not about endless saddle experiments, busted bottom brackets, or knee pain...

When my bike's motor is at idle it means I'm sitting here browsing the forums.

I'm getting ready to head for the southwest, NM, TX, AZ, for a couple weeks. I'll be on my Goldwing, flyin low........

Leavin 0300 Wednesday - my bike will be sooooo lonely.......

Must... not... geek... out... :crash:

Put some pedals on it and you'll have no carb troubles.

(Someone had to say it.)

How refreshing to have a thread that is not about endless saddle experiments, busted bottom brackets, or knee pain...

Actually, I'm with you on this.. ;)

And I'm shocked that there's so many closet motorcyclists on this bicycle forum.... :D

I'm with 'San Rensho' on this. I suspect the idle circuit too, for whichever carb feeds that cylinder.

Take the plug out of the cyclinder and squirt a little gas in it and fire it up. If all three cylinders run at start up, then quickly breaks down to two cylinders then it would be idle circuit carb problem for that cyclinder.

Hope that helps

sell yourtriumph and buy a couple bottles of Makers-- cause the markets crashing and gas is
going up--

A '04 Triumph has carbs? How barbaric. Might also want to check the butterfly-angle at idle and synchronization of the carbs.

And I'm shocked that there's so many closet motorcyclists on this bicycle forum.... :D

a couple weeks of riding on the freeways on a motorcycle got me outta the closet and offa that SOB. and on the pedals (was 1974, As I recall) HUH????

And, a cheap, easy, sometimes works, carb rebuild! Pull the idle mixture screw all the way out, and squirt some carb cleaner directly into it, bottoming out the applicator nozzle. Do it three or four times, and replace the screw. Try it to see if it cleared. Make sure you keep a rag under the sprayer, as it isn't real friendly with some painted surfaces.

This works about 30% of the time, and sure is lots easier than pulling the carb and tearing it down...

Then, start giving it a dose of Seafoam (1-2 oz per tank) whenever it's gonna sit for awhile. Double or triple the dose for longer term storage. Make sure you run it enuf to get it into the carbs before storage. And, keep that tank topped off.

The nice thing about Seafoam is that it's a very good cleaner, a very good decarbonizer, a very good stabilizer, and very good fuel drier. The best of everything, in a can........

I have had good luck using carbon cleaners designed for marine outboards to clean out gunked up carbs on my lawn equipment. Spray a bit into the suspect carb at fast idle. Works really nice to disolve gum or varnish.

Buy a fuelie rice rocket and never hate on carbs again!

... or kraut rocket ...

And I'm shocked that there's so many closet motorcyclists on this bicycle forum.... :D

I actually moved mine from the closet to the garage. Much more room for my V-twin there...

Funny thing is that motorcycles and bikes share at least one thing in common. Upgrading! That pic was taken just after I bought it and it already has aftermarket exhaust (carbon with ti mid-pipes and hangers) and a computer so that I can remap the fuel rates. Since that pic, the rear suspension has been replaced ($900), front suspension reworked ($600), new handlebars ($300), new footpegs ($400), and new gearing/chains ($200). One other thing that bikes and motos have in common. Wive's rolling their eyes at us for spending all our time and money on them.

Actually, rice is one of the worst kind of carbs because the sugars are so broken down. Kraut would be better, there's more fiber and protein.

Man, this thread is hosed.

The problem is quite the contrary: at a certain point, your Triumph became pregnant with another cylinder. Now it's given birth! You might find the other piston in a little nest of shop towels. Don't touch it! If you get your scent on it, your mature Triumph will abandon it! But if you wait patiently and watch from a safe distance, you'll get to see the miracle of where new motorcycles come from!

Man, this thread is hosed.

Scaramouch, scaramouch will you do the fandango?

Now it is!
