Good evening,
I am new to this forum.
But i hope someone can help me solve a speed triple problem.
It is a speed triple 955 '99
I bought this bike from a guy that had for 4 years.
He bought it from a guy ho had 10 years.
But in the 14 years that went by the bike never ran.
So there was a challenge!
I started with valve clearence and timing, this is al ok.
Timingchain tension good.
Next check the cilinders with a endoscope, looks good.
Started the enigine without sparkplugs, this sounded good.
Fuelpump checked out allright.
So fuel in the tank, sparkplugs mounted crossed my fingers and hit the start button.
With a little hesistation it came alive!
It runs ok but with a lot of noise.
Here’s a youtube link
Does not sound like a bigend to me.
The only thing so far i found are the springs in the clutch drum.
Sounds like an air leak from either the inlets or more likely somewhere from the exhaust. Get a can of brake cleaner and spray a small amount around the inlets and see if you get any increase in revs.
Does the noise increase with the revs? Any change when pulling the clutch in? Have you done the screwdriver trick with trying to find where the noise is coming from?
Sorry, I’m a bit late in replying, and if you have engine apart this is probably too late…
Have you tried narrowing down more accurately where the noise is coming from? One trick is to get a big screwdriver or something else solid and press the tip to different parts of the engine whilst at the same time pressing firmly on the handle with the part of your head just in front of your ear. The idea is that sound travels better through solid objects so you end up hearing more clearly the sound at the tip of the screwdriver, which you can use to pinpoint noises.
Warning, using this method, you’ll hear all sorts of extra noises, and you’ll start getting paranoid that things are wrong when they aren’t (Well, I did.)
