    Why Buell stumbles (research)

    I have read it in some forum threads etc. But it was probably only a myth.

    Shall the engine be hot or cold when making a TPS reset?

    I did change my intake seals today against James blue ones, after did i spray alot of starting spray on manifold but no change in rpm. How can i be sure it is 100% tight? Also, do i need to reset the TPS after change of seals?

    XB9 sudden misfire.

    Today did i mount the new HT leads and took it for a ride, the bike runs much better. No misfire at highway speed when open the throttle, no back fire at engine braking and not so boggy at low revs. But it is obvious i have to change the intake seals again, the engine react to starting spray...

    Great to hear your bike worked well, just what i needed to hear so i can calm. :) Acually did i just send them a email about their parts having wrong specs. Must be dicks that not listen to their customers.

    Yes i did notice that but i have seen posts people using them with out issues. I hope it will work, the pressure to the injectors was 50psi. It sucks Quantum sell parts with wrong specs. In worst case will i have to change the regulator.

    Today did i put back the stock Walbro pump, a new hose between the regulator and the metal filter and a new regulator from Quantum. It primes nice, have a good flow when putting the fuel line in a bottle. The fuel pressure was 50psi when the pump primes. Now just waiting for my new ht leads...

    Pump is new. But i will have to remove it and check. I did not change the hoses inside based on they looked like new, but they might be bad. Is it ordinary fuel hose used inside the tank? To be honest do i not think the stock pump was bad, maybe better to put it back again.

    Sounds like a good theory, is it enough to check the fuel pressure or do i need to remove the pump?

    Xb9 main differences about the year

    Is it enough to use the upgraded version of the 2003 belt? Does not a XB9S -2003 have the Thunderstorm?
