You'll also get a lot of heat from the engine that soaks directly into the tank, you can line the bottom of the tank with a stick on foil heat tape that helps as well.

What vent are you running on the fuel cap? If its a small unit with the built in check valve toss it! I've seen more than one fail closed, letting the tank pressurize. A vent line from the tank with no check is the way to go.

Here's a link to some pics on my original 530:

Yo HG....I wanted to check back with you on this. I really appreciate your advice - you've helped me out with this bike a few times. I owe you a beer sometime. Anyway, I tried a few things based on your setup. First, I rerouted my lines - I was running very close to the head and high up on it at that. I rerouted so that The line is going under the carb and sort of laying over the top of the starter. The other thing I did was wrap the exhaust - that made a HUGE difference in the radiant heat! Very much recommend that. I even sprung a bit extra to get the titanium colored wrap so it blends in with the pipe...
I also did the heat tape over the forward portion of the tank - up around the head and radiators. Took two rolls of 1.5" x 15' tape to do it. (Side note: if you decide to do this - TAPE your fingers before you start! You'll be surprised how quick you'll get blisters if you don't)

It wasn't that hot out today and I wasn't able to go trail riding and really push it hard - but I can tell it made a huge difference already. It was idling in traffic and running smooth in the canyons today. Not sure if its really fixed yet, but it's definitely better!

Thanks man!
