Switchback Exhaust Heat
Hi, first post - just got a Dyna Switchback this week. Love the way the bike looks and handles - one problem, so far, is the heat coming from the pipes. I'd like to ride the bike to work for my commute, but with my khaki pants on, I got a blister on my leg from where I accidentally touched the pipe thru my pant leg. Is there a fix for this - maybe a heat shield - or do I need to buck up and buy chaps? Thanks for your help - love this forum!

Most pipes will do that. Gotta Not touch the pipes, especially with thin pants. Stock pipes should already have a heatshield. They run a little hotterbfrom the factory as they are set lean for emissions. Richer mixture will help a bit, but still should get used to not touching the pipes...

Pipes are always gonna get hot. however after switching my pipes out from the stock with the catalytic inside them the pipes don't get nearly as hot. Anytime your stuck in stop and go traffic your gonna notice more heat. As you modify the bike and get a different tune for it that should help some. Losing the stock exhaust will help some too. its all subjective. no matter what you do in commute traffic its gonna get hot. You could always get some leathers to wear over your pants or just wear jeans and change in the bathroom when you get to work.

thanks, the jeans may be the answer. I had a Heritage Classic a few years ago, and no way the pipes got hot enough to burn thru my pants leg - I think it's the placement of the exhaust on the SB - just need to be more careful - and now have a nice tattoo on the back of my leg to remind me :-)

All motorcycle manufacturers have their bikes lean from the factory for emissions, which makes them run hotter. In reality bikes don't put out that much emissions - it's politically correct politics.
Anyway, changing the pipes which gets rid of the catalytic converter, opening up the air intake flow, and using a FI controller to richen up the mixture where it should be, will cool things down considerably.
It's not a Harley thing, they ALL have to do it to please the government.
If you can't do this yourself, it will be a bit expensive to have it done, but well worth it. Your bike will run better and cooler.
Good Luck.

The cat in the collector does get awfully hot. Where I work, live and ride doesn't have much stop and go luckily. I'm thinking of trying doing a wrap under the shield at the cat area. Will replace the pipe sometime soon.
Other than bars and pipes theres not many more changes to the bike I'll make, already changed the AC and put on a tuner and V&H slip-on. I"m getting smarter about riding the bikes for a while before changing stuff. Still have a garage full of handlebars, AC's and small parts to get rid of.Kurt
