Hey all,
I think I have a leak in my air boot that is causing a lean surge and other lean related issues and possibly gotten some crap in the motor so I am now trying to fix before I ride my baby again.
See it you think I am right and if so, what I can to to remedy the problem:
Some background on the bike :
I picked up a 07 EC450 FSR. (Fuel injected 4t)
Basically brand new (was a research bike for a major power sports company and then it blew up and I bought it from a guy who was a tech for them and bought it and rebuilt it)
Anyway, long story short bike is basically brand new when I got it (20 km) and now it has close to 300km so still pretty new.
Shortly after I got I noticed some funny things :
-hard starting when cold (very finicky sometimes refused)
-backfired quite a bit but I didn't think too much of it as a lot of 4t do this
-would occasionally stall on decel after cruising speed and letting off the throttle
-seemed to run a bit hotter than it should have but I nothing extreme
-started bogging between stopped and first, 1st and 2nd
-started hesitating/surgin at cruising speeds (on road) without moving throttle. Not extreme but not right either . Ran kinda jerky like
-IDLED FINE. Not high or low just fine
-gas: 91, non-ethanol pump gas
I started to consider the possibility of an air leK. I have hated how this filter/airbox works from the first place - it's so tight in their it is hard to even get your hands in there to feel for a good seal - let alone see it. Still, I was careful with this.
Despite my effort I think air getting in some where.
On the airboot where the "gasket/lip" part of it braces up against the air box face (on the side in front of air filter) it doesn't look sealed.
I TAPED THIS PART UP w electrical tape, and the "surging/choppiness" went away, seemed to start/warm up better, seemed to run WAY smoother at speed.
Then the tape on the filter started to fail (just a short term fix) and I noticed some noise coming from that area that sounded like a leak .
So I think I have a leak. But as I look at the design of the air boot it doesn't look like this should be possible. It is one piece on to the air filter,.... So....?
Does my diagnosis sound right?
What should I do to fix it?
-do I need to buy a new air boot?
-is there a way to seal the airboot/gasket etc or repair?
-are there any crossover options from other bikes so I can have a "normal" air filter/gasket/easier seal/wing nut? (Never had trouble on my previous YZf or KX bikes)
Sorry long post.
Thanks,
Katrina
