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.

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

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

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

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