damn ! all this time i thought the coil reloc. and tank lifts were to make you bike LOOK cool . and now you explain that they actually DO make the bike cool ! this single video has done so much to make me think differently about bike mods that's it's worth a subscription . thanks !
in past, I would take the horn cover, take out the horn, turn the cover scoop forward, mount it in place wt a made bracket,. the scoop would push air on the rear cylinder. that & an oil-cooler with a smaller or lifted gas tank made a big difference. so you are correct in lifting the tank and directed air scoops. tks
Love this video series. Installed the tank lift kit with the deluxe option as well as the deflector wings. Very happy with the drop in engine temp as well as felt temp. Very happy. Keep the videos coming. Thanks.
Great that you are enjoying the series. We appreciate your business and we're very happy that you're happy with the benefits of the parts. Thank you. 👍
I really enjoy how much I learned from your videos, I live on a tropical country and the specific state where I am is really hot! most of the time over 81F, I run a Sportster 883 from 2004 and I want to know if I can follow the same tips to cool down the engine!!!
Thank you. Glad you are finding the videos useful. Yes, following the same tips on TC and M8's will work on a Sporty too. On a Sporty the best things you can do to cool it down are, coil relocation, tank lift, oil filter relocation and oil cooler.....AFTER you do the basics of a free flowing air cleaner with an External Breather System, unrestricted exhaust with TTI's to stop power robbing heat generating reversion, and a good tune. The following video is a good overview. ruclips.net/video/oRBW50TPQfM/видео.html
Thank you again, for an informative video! Looks like I will have to order the tank lift for my bagger, as well as the deflectors. I am tired of the heat coming up on to me. Thanks!

Only on some bikes, with some aftermarket mods. In the product description, there is a very easy way to see if there will be any clearance issues with whatever mods you have. I have copied them below- It is easy to check for clearance: 1. With bike on kickstand, take the bolt out of the front of your tank. 2. Loosen (do not remove) the bolt(s) at the rear of your tank. 3. Turn your handlebars all the way to the left and raise the tank up your desired lift height to check for clearance issues. 4. Turn your handlebars all the way to the right and raise the tank up your desired lift height to check for clearance issues. Be careful when lifting your tank, you do not want to hit against something (forks, handlebars, trees, blinkers, etc.) when checking for clearance. At the same time you are doing the above, you can also try different heights, to see which one you like best. www.dkcustomproducts.com/gas-tank-lift-kits-c4.htm
The CDW's grab the air at the bottom and below the tank and push it over the engine. The tank lift puts the entire front of the tank higher, and there is a good 5 inches above the CDW's that has a downward curve. This helps push that air below the tank instead of over the top of it. That air joins the air directed by the CDW's and the two together speed the flow up.
I think you are asking about a Tank Lift? If so, most folks go with a 1" or 1.5". But, here is the best way to know what you will like best and which will fit best with how HD mounted your fairing. Link to All Info - www.dkcustomproducts.com/touring-model-tank-lift-kit-dk-trg-tlk.htm Because of small variances in how Harley welds stand-offs & tank ears, also because of variances in where the batwing fairing is bolted on, the 1" Tank Lift can be very useful in making sure there is clearance at full turn lock. Please make sure this mod does not interfere with any components on your bike - like handlebars, turn signals, custom trees, etc. You don't want to end up with a dented tank! Check for clearance before ordering. Checking for clearance not only allows you to insure fitment, it also allows you to see which size will look best with your bike. We are NOT responsible for any damage done to your bike because of the kit. It is easy to check for clearance: 1. With bike on kickstand, take the bolt out of the front of your tank. 2. Loosen (do not remove) the bolt(s) at the rear of your tank. 3. Turn your handlebars all the way to the left and raise the tank up your desired lift height to check for clearance issues. 4.

I have a 2021 Triglide and according to your previous videos my engine temp should not go over 230° and my engine temp should not go over 260° but what should my cylinder head Temp be? Thanks
Oil temp on the M8 should not go over 230, and ET as displayed by the PV should be in the 250-260 range. (and that ET is a display of the temp sensor in the cylinder head. If you are talking about the outside of the cylinder heads, that is something that is more difficult to get a consistent read on, and it will vary greatly, depending on what kind of riding you are doing. You can see where we measure it in this video- ruclips.net/video/6AhPqVlvE-w/видео.html Here is another video- ruclips.net/video/qMVwT0nunfU/видео.html And here is a written report at this link- www.dkcustomproducts.com/force-flow-fan-test-report.htm
What about keeping the cdf installed on both sides and the cool flow fan that harley makes? Does it help to cool the rear cylinder efficiently or is it just for comfort of the rider and passenger?
It is effective at limiting the heat felt by the rider and passenger, but as HD states in their description of the product, it is not effective at cooling the engine at all.

I do not know what bike you have...but 1.5" gives a lot of extra air over the engine, and going higher than that does not give that much more. Going higher is something to do for looks/see more of the chrome.
Dag nabbit. Lol. I should have thrown the tank lift into my order from the other day. Ill have to place another order tmrw. So the tank lift will fit a 2017 Slim S 110 ci. Is that correct? Thank you DK.

Unfortunately the Twin Cam and M8 run too hot for their own good, both in slow/stopped traffic and at interstate speeds. The sweet spot of 40-55 mph is where you are getting a good amount of wind, but not working the engine hard. But even at those speeds it runs too hot. Speeds of 70-90 mph that engine is working much harder (generating heat) than the accompanying wind can dissipate. To put it another way, if you are fully warmed up, then idle at a stop for 5 minutes compared to 75 mph for 5 minutes, the engine and oil will be hotter after the 5 minutes at 75 mph than it will after 5 minutes of idling.
Sportsters, including 2018 and newer, do not have near the heat challenges that Twin Cams and M8's have. We talked a bit about Sportys at the 1:08 mark in this video- ruclips.net/video/rWOdQOtDv6A/видео.html
@@marchnte That's a bit too hot. You want to see that peaking around 375 from the heat sensor. There are a couple of things you can do- Make sure you have a free flowing air filter with an External Breather System...so you are not feed hot, oily, oxygen depleted air into the combustion chambers Make sure you have a good tune that is getting a good AFR and not too far advanced timing Get that coil and all the plastic out from on top of the engine so you have better air flow If your ET is that hot, your oil may be going over 230-250. If it is, add an oil cooler to get those temps down, also beneficial is an oil filter relo.
