2008 Spyder poor performance

[Hogzila]

my Spyder has been running great, except now when it warms up, it seems to be missing /hesitating, if I stay in a lower gear. when i come to a stop it seems to hesitate on acceleration
its a 990 semi automatic, I have replaced the fuel filter, change oil as required, the issue reminds me of leaking intake manifold gaskets on an air cooled V twin, but it doesn't start acting up until the motor heats up to operating temperature, but the symptoms are reversed.
ANY HELP WOULD BE GREATLY APPRECIATED.

WELL - MAYBE

Do to the age .... it could be the VACUUM hoses , they develop micro cracks that are almost invisible ....re-place with Silicone ones of the same size.......OR the plug wires are very fragile and don't age well either re-place with some from BAJARON they will last forever...... Check the hoses first .......Mike :thumbup:

Pinch off the purge line at the valve and take it for a ride.

:agree: with Mike...
Could it be those original Sparkplug wires? :dontknow:
Contact BajaRon, and get yourself a set of wires that is worthy of your ride! :thumbup:

Bummer...

Would start with the vaccum hoses to the throttle body...

cold and at rest they look good....

but they dry out and when hot get soft stretch and leak...
