You can check the temperature of the cilinders with a laser temperature gun (don’t know how they are called in English). You have to make sure though that you can set it on measuring metal. When you are done with your cilinders you can use it in the kitchen. 🙂
Save yourself $400. Spend $25 on 16' of 3/16" (0.187") ID clear plastic tubing and some red transmission fluid (Marvel Mystery oil works too). Zip-tie a 2.5' loop to a yard stick and inject 20ml of red fluid into the loop. Warm the engine to operating temperature. You'll have two 5.5' lengths of plastic tubing to take vacuum from the 3/16" ports on each throttle body; they're the ones with the small plastic caps. If necessary, balance and set the TB's at idle with no throttle applied using the 3/32" hexhead screws & 5/15" locking nuts on each TB, matching the fluid levels on each side of the loop as you adjust to the desired idle speed. I set the idle just high enough to extinguish the alternator light. Then balance the TBs at the cable adjusters holding the throttle off-idle to around 1000 to 1200 RPM. This procedure applies to Urals 2019 and newer.
Thanks for the video, that looks like an effective and pretty straightforward way to balance the throttle bodies (or carbs) on a bike. BTW, do you realise the right cylinder is a couple of inches further back then the left cylinder on a Ural and BMW boxer engine?! So unless you have a size 14 left foot and a size 8 right foot, I'm not sure the warming of your feet is a very accurate method to check the balance of the throttle bodies or carbs! The smoothness of the engine at idle and at revs (which was noticeable in your video) seems a much better yardstick of how well balanced the TBs are! 😉
Hi there Keith. Coincidence would have it, that I too purchased a new calibration kit as I couldn't source one the same as yours. So, bought an electronic one. No rods, just a bar graph and damping system. Plugged it in to Ruby for a quick test and balance was bang on. As you would expect from new. If you are looking at OBD2 for yourself, I got lots of help from Lee for DIY. You only need the right plugs, a device which transmits Bluetooth or wifi, and an App for your phone. Still waiting on the last plug to come from a place which shall remain nameless. Then will try it out. So far it's under $100.
@@CreakyRider I am interested too in a OBD solution that is not so ridiculous expensive as the original sold by Ural..... The software can be downloaded for free.
@@CreakyRider I haven’t. Seems to be running fine though. I will need to drill and tap some ports in the throttle bodies to sync. I have adjusted the idle though…
@@CreakyRider Maybe you can do it through the OBD port, but not sure - not to mention I don’t have the Ural diag program. Maybe a good project for when it warms up. I searched for a tool, but they appear to all use vacuum ports (lots of adapters like yours has).
@@Uraljunkie yeah , cool , a little research project. I’m in the process of getting an OBD setup , just ordered some plugs and cables etc , we will see if I can get it to work.
What year is your Ural? My new to me 2023 has Electronic Idle Control. So go are the days of sync the idle then at higher RPM, now it is just higher RPM.
Yeah mine is a 2020 model , I think it’s just to make sure the cables are pulling evenly on the throttles. Mine was a little bit out , I need to check it again next time I do a big service.
Should you adjust the vacuum at idle or at part throttle also? I am asking because valve clearances variations apply on the vacuum also. So if I have adjusted the same vacuum at idle that means that I shouldn't apply any throttle and call it a day? Or same vacuum at idle doesn't mean that I will have same vacuum readings at part throttle?
Hi Creaky.... So what do you think about if we will be able to get parts for our Urals... Some parts places here in the U.S. think they will be able to get parts from other countries... or filter parts out of Ukraine or Russia to other countries so we can get parts, what do you think are parts we should get now ? I sent for Oil filters and should get them next week.
There are alternative oil filters , Ryco make a compatible one , there are people making gaskets etc. I don’t see general maintenance as a problem. A major rebuild or something might be a problem in the future , we don’t know , let’s hope for peace , not just for our bikes but for the people.
Do you have to cut or trim anything.?? I have read where the stainless steel rods have to be cut certain lengths depending on the type of motorcycle. Did this have to be setup FOR the Ural.?.
No it's all ready to go. It comes with a piece of clear tubing to use for restriction (damping) you just cut a couple of pieces with scissors and add them to the tubing , very easy , and it all work perfectly. It has very good instructions and also more stuff on their website.
