I pulled the snorkel out and cut two 1" holes in the top of the box when I first did the Procycle mods to the original carb. When I installed the TM40, I went to a Twin Air air filter for better breathability. It made a big difference in letting the engine breath. Also, I run CR9E spark plugs which are a little hotter plug. They give a better burn on ignition. The misconception when saying the plug is hotter, it really means that the spark lasts just a bit longer than the CR10E, giving a better burn of the fuel in the chamber.

Yes, it has a Salvage Title. The cost of repair by a shop plus the amount (cost) of replacement parts was more than the considered value of the bike. I bought it back from the insurance and received the overage amount they decided on as payment. There is nothing wrong with the bike as all damage was cosmetic dings. I don't plan on ever selling the DR, so it doesn't matter to me that it has a salvage title.

I first tried the mods to the original BST Carb and took out the snorkel and cut two 1" diameter holes in the top of the breather box. I have not cut any more holes in the box, but I have switched to a TwinAir intake filter which provides a better airflow into the carb. Hope this helps!

Hello @simenthorvaldsen, I will need to look through my old notes about what jetting was used. I bought my TM40 from Procycle pre set up for my bike and what exhaust it has plus the altitude range I ride in. After initial start up and and about a 10 mile ride, I only had to make a small adjustment to the idle speed.

I bought the TM40 from Procycle. They ask questions about your bike set up, and then set up the jetting based on your bike and where you ride ( altitude). Other than a small adjustment to the idle speed, I have not had to adjust anything on the TM40. The bike starts right up all year and runs great in hot or cold weather. I ride in an area that goes from around 500ft to 6000ft and I dont feel any difference in power.

ill be honest - i've never seen 60mpg, even on stock carb and jetting

Me either 👍🏻 I go by hours riding not mpg.

Same. Stock fuel consumption isn't great.

Not sure what you are referring to for 3 options. As for the TM40, I emailed with Procycle about my bike and it’s mods and they set up the carb up before shipping based on what I told them. I have not had to change any of the settings on the carb since install other than a very minor turn of the low speed idle screw after the initial first ride and warm up. Hope this answers your question. Thanks, Gary

Thank you, Roberto! I do not have a video on the Acerbis tank. Do you have any questions about it? Let me know and I will answer what I can.

Thanks!

Thanks, Matt! The light is a Braun 390 Lumen from Harbor Freight. It is an awesome little light. You can find it on sale all the time for about $24 As for extra hoses, if you are referring to the smog hoses, I eliminated that system. If you mean the hoses from the carb, I routed them down the back of the cases and then shortened them a bit. I bought my TM40 as a kit from Procycle and it came with low friction throttle cables. They slide super easy with no binding. I have 2” risers on my bars and they do not interfere with operation at all. Good luck and get ready to be amazed at how much better your throttle response and overall performance has become.

All depends on where you live. If you live in the LA Basin, then yes, this could be done as a one day ride. It is near Cuddyback Lake. The turn off is about 13 miles north of Kramer Junction on Highway 395. From there it's about a 22 mile ride in to the memorial.

Thanks!

The carb helped a bit with decel popping, but it will never go away as that is inherent in 4 stroke singles. The SS1 muffler and header pipe made a bigger difference in decel popping than anything else I have done.

@@duelmen3 I like the popping.

@@divebobber I like the popping on decel as well. But, I ride in the National Forest most of the time and some rangers are picky about noise levels and can be a bit vocal about the noise level.

Thanks Stephan! Not sure on which ones were used. I will have to dig through my papers from Procycle to confirm. I live just south of Redding in Anderson. This is a great area for riding. I need to get up to your area to explore 👍🏻

Cool! Hope it does too 👍🏻

I did put a second petcock on my Acerbis tank. It isn’t linked into the carb though. I have a short bit of fuel line plugged at the end that can be easily removed to drain out fuel to help another rider in need. I have never used the reserve on the tank even on a two day ride 👍🏻

Thanks! I have a longer video of all my mods in the works. Hopefully ready by next weekend to post.

@@duelmen3 Looking forward to it : ) - subscribed

I felt the install was pretty straight forward for me. I did pull a few more items than what they tell you, but, being a wrencher myself, I felt it would make the overall install easier. Hook up the pushme pull you throttle cables at the carb, then at the throttle. Makes the hook up easier then fine tune the adjusters. Good luck and enjoy that new carb! Let me know how it goes 👍🏻

Hey Robert, I had done the standard mods to the original carb and I bought the tail end of the exhaust first. Things were much improved, but not where I wanted it to be. I come from a 1970's 2-stroke background and I want that turn the throttle power band in my mind. I also did the grind of the header flange and didn't really feel any improvement from that mod. Coming from a mechanical background, I know the pumper carbs are much better at fuel/power delivery, but the cost was a big consideration. I actually had ben putting $$ aside to buy the carb. I emailed with Procycle about my riding style and current / potential mods and they set up the carb pre-delivery. I have not had any problems with the carb set-up and am very happy with the performance gains. I turn the throttle and the front will lift right up if I want it to. It never had that quick of a response before. I bought the header pipe after Christmas and it helped to smooth out the powerband even more, making the exhaust even sound about as quiet as the original until you twist the throttle. The biggest reason I chose the combinations I did, was they all have been set up to work together by Procycle and there is little to no maintenance involved, I didn't want to repack the pipe every now and then... Gary

Thx for the quick reply Gary. Just what I wanted to hear!!

Shasta/Chappie OHV Park near Redding California

@@duelmen3 Sweet, thanks alot.

Thanks, Rob! I grew up riding in the 70’s as well (teen years for me) out in that desert area. The are hundreds and hundreds of miles of road and trail out in the desert. I live in Northern California now and it was an 8 1/2 hr drive for me to get there. Where I live, I can ride out my door and go riding in the mountains on great Forest Service roads. There is also an OHV ( Off Highway Vehicle Park) with over 220 miles of trail and roads about 20 minutes from my front door. Lots of great riding out here in the West. Enjoy the Mighty DR and safe travels!

Weetabix, with so few videos on the TM40, that’s why I made the video. Glad you liked it and hope it will help you if you decide to do the upgrade. If you look at the reply I made to Robert Eddy, you will see why I haven’t done a follow up video yet. I am heading down to the Southern California desert in a week to do some riding and I will post a video of that and talk a bit about the upgrade. Hope the snow melts out soon for you!

@@duelmen3 j Just read about your first test ride. Glad to hear all turned out ok. Looking forward to a review on the bike when you're able to really test ride it.

On my way home from the first full day ride with the TM40, I had a car run a red light and turn in front of me. I went down on the pavement at 40mph and slid for a nice long way… My DR ended up being totaled by the insurance company and I bought it back and have since rebuilt it. Most damage was superficial scratches, but there was some items tweaked that took some time to replace. I finally got a few more rides in last Fall and yes, there is a big difference between the stock carb, with the standard mods, and the TM40. The front end pulls up with little effort and I have a 5.3 Acerbis tank! The mpg seems to be better as well. I really like that it will chug along at idle or small amounts of throttle input at slow speed maneuvering. The power comes on instantly and will even come up fast when in the wrong gear, lower speed - too high a gear. I feel it was money well spent on my DR. I also emailed with Procycle about my riding style, weight (me) and mods I already had and was planning to add and let them set it up. I have not made any adjustments to the carb and have not felt the need to.

@@duelmen3 Thanks for the quick reply! The crash on the test ride really sucks and glad your ok and back in business. I just did the full Cogent suspension upgrade for my weight and riding style and it really is a game changer. I sent forks to them and had them totally rebuilt with there DDC cartridges and preload adjusters. Bought there Mojave Pro shock with remote preload adjuster to. Was not cheap but totally worth it to me since I plan on keeping the bike forever. Next up is gonna be TM40 with LeoVince exhaust.

@@roberteddy1951 I went with FFRC Plex valves from Australia. Upgrading the front and rear is absolutely a game changer. The Mighty DR is a whole different machine with the suspension upgraded! I went with the Procycle SS1 exhaust and header. Another great addition in the fine tuning of the bike. I am heading out to the Mojave Desert in a couple of weeks and should have some new video of the desert ride to the Husky Memorial after I get back. Can’t wait to ride in the desert again!

Hey Captain Tom! I love the TM40 carb. The difference in performance is amazing. Much better control at low to no throttle at slow speed. The acceleration response has no hesitation and the mpg has gone up. I dont keep track of mpg other than I know I am going farther on a tank of fuel. I recently bought the Procycle header pipe to go with the SS1 exhaust I bought last year. Not too much different than the stock header with the weld ground off, but it is a bit quieter and has less decel pop. Enjoy your Mighty DR!

Thanks, Sacha! Hope my video helps make your TM38 install easier for you. As for the oil cooler, that is a factory part that comes on the DR650.

thanks!!

Thanks! Glad it helped your install 👍🏻

Thanks, Kyle! The flashlight is available at Harbor Freight. Braun 390 lumen slim bar led light.

Thanks! Hope your install goes well. I would love to hear how it goes and how you like the TM42.

Steve, hope it was helpful! Enjoy that new carb 🙂👍🏻

Danke! I have a video in the works. I was involved in an accident with a car at the end of the first ride with the new TM carb. I am okay, but it is taking some time to get parts to rebuild my DR. Where do you live? I was stationed in the town of Duelmen for 3 years in the 1980’s.

@@duelmen3 crazy, hope you heal well and get back on the streets soon. A rebuild would be interesting, take your time. I live in Berlin, but know some people near du Dülmen, been there many times. Thx for the answer

I wanted to see what others had done before as well and just couldn’t find anything. Thanks for watching!

What sort of exhaust pipe is that? Did you find tuning the tm40 reasonably straightforward?

@@pyle9797 So far, the tuning has been minimal. I have the Procycle SS1 exhaust. It is a copy of the Suzuki GSXR pipe. I gave them a list of the mods on my bike and they pre set the carb accordingly. The only thing I have had to do so far is lift the idle speed a little.

Nice pipe that one.looking at getting one my self. How you finding the sound of the ss1? Not too loud? I just got the procycle seat cover kit put on last week and I highly recommend it. Soo much better than the stock seat

@@pyle9797 I did the Seat Concepts diy kit last fall. It is a must and so much better! The SS1 is just a little louder than the stock but really helps to open up the power band. I also ground the weld off of the exhaust header.
