So I thought that the purpose of a heat shield is to protect me from the heat? I burned my leg some small scarring twice on this motorcycle.

Is there anything that can be done to protect our legs on this exhaust? I owned a Suzuki Boulevard M90 cruiser awhile back and never had this issue.

I love the chief it's just a leg burner for sure....

Most people feel wearing shorts and such on a bike is the norm. I have never burned my leg on a bike wearing jeans, quite the opposite wearing shorts. The heat shield is not there to block all the heat from the exhaust. It's not magical in that way. It does "shield" you from most of it by way of an air gap, but metal still gets hot, especially given it is connected to the pipe in several places. Wrapping the pipe would definitely reduce the heat further, but it will never not be hot

I am NOT an advocator of wrap but needs necessitated me fitting it on my Scout. I was burning boot tops and pants. If carried out carefully and with a good quality 1” wrap and by utilising a high temperature paint to seal the fibres afterwards the results can look quite good and be totally functional. Mine was a result of ‘function over form’ but it worked for me!

There’s a company that makes a flexible heat shield that attaches inside the bike’s heat shield. However, I don’t know how effective that would be. I can only think of three things to address heat - remove cat, better tune, and wrap exhaust. However, research wrapping exhaust before proceeding - some have experienced the wrap trapping moisture and rusting pipes.

Two points if the pipes are stainless (mine are fortunately) they won’t rust, secondly the whole point of applying the paint to seal the fibres is to keep the moisture out!

My RM trike runs HOT according to my PV3 ,I have seen 358 degrees, I dont get the heat like a lot of people are talking about burned legs & Nut Blisters. I think The Question you should be asking is why my bike RUNNING SO HOT ? I rode new Challengers & Pursuits @ Laconia I felt more heat off those bikes than mine. You must be in 400 - 450 degree range ? One day when I got nothing to do I'm going to pull my heat shields off, go for a ride & see what the PV3 temps are ?

The other thing about the Chief's exhaust design... right where you put your leg down is where the cat is, which is the hottest portion of the system. Which also leads to the question, can you put exhaust wrap around a cat?? Since the cat is designed to get hot to burn off excess emissions, does it get too hot and would that cause damage to the wrap and/or cat itself? Not saying it can't be done, I just genuinely don't know...

I've got over 150,000 miles on my Chief, Larry S. put over 500,000 on his. Both are completely stock, which means we should both have well done right calves by now. Funnily enough, I have never even had any discomfort on mine. Of course, I wear tall leather boots and long pants when I ride, so that might be the trick.

The new chief(2022/2023 i think) has a cat where you put your right leg and it cooks....even without the cat i added an extra heat shield....i would not have purchased a new chief had i read this forum first i would have got one like yours Whizz

I deleted the catalytic converter and it made a big difference in the heat I felt while riding. I installed the Tab Performance version. Although the dealer did it, they said it is an easy direct bolt up process. That was a year ago.

Today, I am told, when you buy the Tab kit, you are required to buy, but not install, the catalytic converter. That adds some to the cost obviously.

I have to be very careful when at lights or somewhere with my feet down not to burn. Stagger the legs wider where you can. Took a while to get the muscle memory going, but I can now walk the bike without burning myself. It's due to the width of the engine. Some people wrap their pipes under the decorative covers which could help.

Ok , when you come to a stop at a light my class 6 driver instructor says you should leave your foot on the brake and leave the bike in first gear. Balance with your left foot on the ground. This way also you don’t burn your leg as well if you have shorts on.
man running these thunderstrokes 116 in Texas must be crazy hot on your bikes when it’s 120f outside. I can’t even imagine riding in that heat!!!! I find mine hot up north in Canada when it’s 75f!

If you insist on running the risk of losing a lot of skin if the bike goes down wearing shorts, try an archer’s leather arm guard around your lower leg. Sizing should be pretty similar.

I ride my '22 Chieftain LTD regularly, wearing shorts, and never get burned. PAY ATTENTION and keep your legs away from the engine/pipes. Not getting burned is just part of learning to ride. (in my humble opinion) I'm 75, and riding since 15, on 12 bikes. Maybe it's just a learned skill. In the meantime....long pants and boots should fix the problem.

Occasionally, I’ll feel the heat on the inner side of my right leg calf when riding my 22 Chief, never to the extent where it’s a concern for me. As for my 2017 Chieftain Limited, I decatted the exhaust, which reduced the heat drastically.

I was bit a couple of times when I had my Chief. Both times it was when I moved the bike from my backyard into my garage when wearing shorts. The exhaust was still hot when I waddled it into the garage, wasn’t paying attention, and got got branded.
I always wear jeans when riding and never got physically burned while riding, but my legs and nether region would definitely cook when it was hot outside! Thicker jeans help deflect/block some of the heat. My Rokker original jeans are awesome - they’re pretty thick and have a Kevlar lining - but they’re pretty warm to ride in. There’s the trade off.

the problem is the exhaust is right as well as the catalytic converter.

Even on my Pursuit my right ankle area gets toasty warm. Not much way around it anymore.

Tape will help a bit but it's still gonna burn you given the chance.

I'm wondering if you're a shorter person? Maybe try and use the left foot down only option.

This is where the hill assist like HD's have would be helpful, however it also requires you to keep the clutch in and 99% of the time at a longer light I'm in neutral. Not what's recommended but it's what I do

Any way to de-cat while keeping the stock headers/exhaust?
IMO Left foot down is the way to go on any bike.

Yeah i am on the shorter side under 6'0". Where forward pegs on this bike are uncomfortable....hence why I went with Mids
I also under 6'0" and I feel more comfortable with forward pegs on longer rides, mids are nicer to go on twisty roads, but the pegs scrape easier.

You may want to try using a heatshield kit from DEI (Design Engineering). Vehicle Specific - Motorcycles / Powersports - Page 1 - Design Engineering, Inc I'm using a kit on my 20RM. Seems to help.
I have those installed, they help but not significantly. The inner side of the leg will still get uncomfortably hot at stops.

All and all I think that what would really help this engine run less hot is to get the O2 sensors delete. Unfortunately, there aren't any available for Euro 4 & 5 chiefs yet. 🤞

Hmmm...sounds to me like a good tune would moderate the heat better
