Exhaust heat very hot in traffic

[sebastienb]

Hi Guys,
This week drive has went form 5 miles to 20 miles with traffic and my bikes temperature gores up to 4 bars ( 2011 monster 796 ) and when it gets that hot i can feel the heat on my left leg pretty bad specially when stopped in traffic. Could it be because of how i change gears ? when riding in traffic i'm less aggressive and ride the gear to 4-5k rpm instead of keeping longer. Is there also anything i can use to lower the heat under there ?

One last thing... how high does your temp go when riding in traffic ?

thanks

what kind of pants are you riding in?

ceremic coating your pipes can save you some level of pipe burn...but traffic will still be traffic and the bike WILL heat up...

[sebastienb]

Riding with regular jeans. Is the ceramic coating expensive ?

[thought]

It's your rear header, ceramic coating will drop it a bit but not that much.  It runs about 300ish for it... another option is wrapping the header but that can rust your pipes and will fade quite a bit over time.

The 696/796's all have the same heat output, but the new 1100evo's routing supposedly helps reduce it.

and wearing moto pants or at least kevlar lined jeans will def reduce the heat felt by your legs.

basically that is just riding in the heat with traffic, the natural heat form the bikes weather air or water cooled is going to get you hot no way around it, especially with the routing of the pipes.  good luck and just try to stay out of traffic or take a break every few minutes i fyou are really feeling hot.

..... and to answer the other question, 4 bars in hot weather/heavy traffic is normal for my 796.  Hot legs and hot place where legs join torso are also the norm

I dont know what the law is over there with regard to going through stationary traffic (its legal here in the UK) but it might stay cooler if you can spend less time stuck in long lines of cars and can get straight to the front of the queue.

My old 996 used to do this really badly on the right - there was nothing to do but let the family jewels get cooked I'm afraid

It's simply a combination of radiation (mainly infrared) and convection (hot air) hitting your inner thigh due to the placement of the rear exhaust header.  This would happen even if the bike were water-cooled.  The gap in the subframe allows that radiation and air to strike your leg directly.

An option which would likely help would be to cover that gap with a reflective material facing toward the exhaust header.  The downside is that parts of your bike in that area would then become hotter, but you'd be more comfortable.

Where you riding?  In Phoenix, my 620 would run well over 300 temps.  Metal tank burned my legs often.  Sometimes I wore a pair of shorts under my pants so I didn't get the inner thigh burns.  I wrapped the header as well.   

The 1100, with it's funky pipe and undermounted exhaust, was immediately ceramic coated after the skin on my leg became one with the pipe!  This didn't cut back on the heat output much.  If you have the new gen Monster, talk to Mark and get yourself a Boomtube.

I'm in Miami, boom tubes would be nice ! It's not too hot out maybe 80 degrees. Who's mark ? And how much for the tunes ?

I was living in Jupiter and around the panhandle.  It does get hot and humid down there.  The new gen Monster doesn't like that!

Yeah, talk to Mark at MotoCreations.  He has a few pics too of your bike with the pipe on it.  Cuts a lot of weight, they're loud and they'll save your legs/azz from burning up! Look at the sponsors on the left if you haven't already.
