I've searched and read on the forum about my issue, which is my GT200 will slow down and hover around 60-65 mph top speed after about 30-40 miles of riding at 70-75 mph. If I pull over, or even ride slowly, it seems to get better and then will be fine for another 30-40 miles at high speed.
I've recently had the belt and rollers changed, and all's good there.
I do still have the evap system attached, and I notice when unscrewing the gas cap definite pressure after a long, hard ride.
So, I'm thinking of disconnecting the evap hose off the carb (and putting a sponge filer over the car).
What are thoughts on then cutting the line on the evap that goes to the canister vs. just drilling a small hole in the gas cap to deal with the pressure issue? Pros vs cons appreciated.
Obviously, if you can think of another cause, let me know.
Thanks,
Eric
