Hey guys,
Just wondering if you have any excesses Heat off the Rear cylincer of your bike. I put the Dragula, Zippers and thundermax tuner on mu 13 RGU, with a Base Map from Drago's and that damn Back cylinder temp is very excesses. The Heat hits me right in the middle of my Hamstring. And it is Hot. It has been only 75 degree heat here in MN and I don't want to ride the bike.(Yeah that hot). So just looking for anymore Idea's. I thought with a Base tune and Auto Tuner I shouldn't have to pay $350.00 for a damn Dyno tune. Sorry to Vent, was going to try Thundermax tomorrow and see what they have to say. Anybody here in MN know of a good Tuner, or what Base Map are you running? I think I', at 274 Base Map.

I'm running a 10.5 compression 107 wih heads, cams, etc with a PC5 and auto tune. Mine is nowhere near hot. That being said, I put mine on a dyno for a good tune and set the auto tune from there. Personally, I don't think there is a replacement for a good dyno tune. Finding a good tuner can be tricky though......

Have you pulled your plugs? What color are they? That will probably tell the tale in a quick hurry! I'm betting they're burnt white!

I Have the same problem. I came to the conclusion that its just a hot as pipe. I've called Tmax & they advised that my map is correct & everything is working properly based on the data that was collected & sent to customer support. From "MY"personal experience, the Tmax is not user friendly & over rated. JMPO. BTW, I haven't talk to a local tuner that recommends Tmax.. But I don't know if that men's anything..

Are you running the 2-1 Dracula. Seems like a lot of folks don't like the heat that 2-1 pipes put out on the right leg.

I Am running the 2-1 Dragula. It sounds awesome. I to am having a hard time finding a tuner that actually supports the Thundermax in the twin cities. So far I call 3 Independed shops and they all seem to have different opionions as they sell different brands. So I have a riding buddy with 11 RGU with 2-1 Basanni and a SE tuner and that thing is nowhere near the heat I have. So I hope after I spend another 300.00 on a tune this beast settles down or there will be a Dragula up for sale.

Heat! I know! I am running a 120r with a thundermax and dragula.Heat was unreal. I talked to Frank, changed to the 3.0'' baffle and removed the doors on my lowers. Helped a lot. Waiting to see what its going to be on a 80 degree day. Are you running lowers? Remove the doors or the whole damn set.

Removing the doors helped me, but I think its just how the pipe is. The way the rear header loops out from the rear cylinder, brings it closer to your leg. It comes out further then most 2-1, that why more heat is felt - coupled by it just being a hot ass pipe. JMO.

Its the 2-1 headpipe. The way it sticks out lets the heat radiate a little closer to your leg. The stock headpipe fits behind the heat deflector but because of the way the Drago's pipe is shaped you have to trim it if you have one. If you didn't have a frame mounted heat deflector to begin with then you may not have noticed the difference on how the rear pipe is angled outward some more.

I have the Kuryakan frame mounted heat shield & the pipes still bends out further than the shield & HD one as well.

Q-Hog if you look at some pics of Drago's 2-1 you will notice that you have to actually cut a notch out of the factory heat deflector to make it fit. Not only does it stick out further its also angled higher up then the stock pipe.

When you do mods to the bike the engine usally will put out more heat. Many dyno tuners don't support Thundermax because they don't sell the product or they haven't had any experience with the T-Max tuner because most of the time the T-Max tuner doesn't need dyno tuning. The heat is coming off the Dragula exhaust and the heat is 1 of the reason that I took my Dragula OFF my bike and went back to my V&H big shot true duals, the Dragula was too close to my right leg and the exhaust made contact with my leg at times. I find the T-Max auto tuner very user friendly and for my limited computer skills it was easy for me to learn how to make adjustments and collect data.

I'm running a 2 into 1 V&H Pro-Pipe and the Power Vision Tuner and I have the same issue. Never had this on my 06 EG but I know the newer bikes were having heat issues. Hence why they came up with the idea of the rear cyclinder cut off when it idles for a bit. I took a short ride in shorts yesterday (yes, I know) and it liked to burn right through the skin. I think it's just the way it is on thses bikes. (willing to bet other brands don't have this problem).
