  1. It appears to be a K750. KMZ randomized serial numbers so captured motorcycle serial numbers including those on transmissions, engines, and frames, would not reveal any information like types of motorcycles produced and the number of motorcycles manufactured. Originally KMZ products were limited to domestic and approved foreign military sales. They continued that practice despite asking for and receiving permission to sell to civilian's and to countries that allowed import or Russian motorcycles and motor vehicles. That means those serial numbers you provided contain no useful information. Can
  2. Dnepr MT's have a hand clutch lever and the transmission presses the clutch arm for you when you press down on the toe or heal shifter pads when shifting. You can up or down shift by just pressing down on the shifter with your foot. This is built into the transmission at the factory it is not something that can be added to a transmission if it did not come with it. Ural and Dnepr transmissions are interchangeable so a Dnepr transmission with semi-automatic shifting can replace a Ural or older Dnepr transmission without that option. If you are looking to switch to a "suicide" clutch setup where
  3. Here's a link to new needles with the flat washer shown on the end of a needle. It's not an "O"-ring. From the looks of it there's no way it would survive the ethanol contaminated gasoline the sold out to the farm lobby Politicians have forced on us here in the USA. http://dnepr-kiev.com/spare-parts/fuel-feed-system/Fuel-needle-assembly-for-K63-K65-carburettor-with-seal-DNEPR-URAL-set-10-piece-1458?filter=1 Even the no-ethanol gasoline sold for small engines at some service stations end up with with small amounts of ethanol in the gasoline. It's up to the truck driver to mix the etha
  4. When I purchased my Dnepr it had Chinese K65's installed and a set of original Pekar made K65's in a box with some other parts. The Chinese carburetors were junk even while looking almost new. I don't think they ever managed to get them working properly. I looked at the Pekar carb's and found clogged up jets and passages much like you describe the condition of yours. I had to run a tiny drill bit one step smaller than the hole in the idle jet on one of the carb's because that was the only way to get whatever was clogging that jet removed. I have a set of drills just for drilling out jets, whic
  5. I got two of those float needles from my local small engine shop that had them in stock. One of them worked fine in one k65 but still had problems with the other one. After looking at the area where the needle seats I noted it's just a sharp square corner. The needles should sit in a 35 degree 'V' to seal properly. I had an old 3" long 1/4-20 bolt in a bucket with other hardware so I cut the 7/16 hex head off it, chucked it in my lathe, set the compound to 35 degrees, and cut a smooth 35 degree point on it. Then I measured the inside of the 'tube' the needles sit in and turned the bolt down ju
  6. I wish I could go but I live across the Atlantic in the USA. For some reason real rally’s disappeared in the 1980's here in the States. It's sad because I enjoyed them. Now all we have are little 2 hour rides and hot dogs afterwards. They are not even close to the fun a weekend of camping and fun of a real Motorcycle Rally.
  7. I've been watching Russian and Ukrainian Ural and Dnepr videos on Youtube and have seen a new product from AliExpress that adapt PZ30 carburetors to Ural and Dnepr heads. The manifolds bolt to the heads just like K65 and K68 carburetors and rise to a flange for the PZ30 carburetors so everything is just bolt on and go. They also raise the height of the carburetors to provide more clearance between the carburetor and the shifter on the left side and brake pedal on the right. One Russian Youtube'r even opened a box with a kit with the PZ30 carbs, gaskets, and cables in a kit. I have searched Ali
  8. I use Autolite spark plugs on my old Dnepr as well. They are good plugs and the internal resistor has never failed on any I've had.
  9. My Sovek ignition survived an Alabama August with no issues. I've been reading about Sovek ignition issues about transistor problems and hot temps. Apparently one of the inspection stations that was testing them was overheating them with faulty equipment. They tested good but the units that went across that station later failed in use in hot weather. I suspect that some of the components such as resistors and capacitors were damaged causing their values to change such as capacitors opening or shorting across the leads and resistors opening or their value changing to something much lower in va
  10. Here in Alabama it hardly ever snows but when it does we take the day off and play in it! I made up some snow chains for my MT-11 just in case we get some.
  11. The differences are gobs of low rpm torque and it's really quiet. I have some really steep hills where I live and ride. Before the stock exhaust I needed to be in first gear to go up them. Now second gear is fine with no engine complaints on the steepest one and with all the others all I need do is drop into third about 2/3rds the way up and all is good. The one is exceptionally steep. So steep it's difficult even for a healthy person to climb, and I do mean climb. Most people in my area drive the long way around to avoid it. Before the stock exhaust I would come to a near stop at the bottom a
  12. Glad to have the forum back! Thank you so must for the effort you extend to make it possible.
  13. Good to have the Forum back and working again! I've have over a 1,000 Km on the 2 into 1 KMZ exhaust system I got from Arbalet Ukraine spare parts. The engine still likes it. I have much better low in torque now and the carburetors tune properly and stay that way. No more randomly mis-matched synchronization issues. Apparently a Dnepr 650 engine must have the correct exhaust back pressure for everything to work properly.
  14. I used the Walbro float needles in my K65 carbs. They worked fine on one but I still had trouble with the other carb needle not sealing off the flow. I turned a 35 degree point on an old 1/4-20 bolt and cut a shoulder on it on my metal lathe so it would just drop in the carbs where the needles seat. Using a small hammer I hit the end of the tool so it would impart a small 35 degree angle where the point of the needles sit. Now the ends of the needles with their 35 degree points sit in a hole that matches them. No more leaking needle seats! That fixed a lot of other carb problems I was having l
  15. I'm going to replace my sheet metal pan with the deep aluminium sump as well. I used the black oil proof RTV sealant between the rubber gasket and engine and steel oil pan. I took my time putting in the screws and using a torque pattern as used on heads. No leaks or distortion was encountered. I want the larger sump more for the added litre of oil and better oil cooling more than anything else. Currently when the oil is down on the dip stick about 3/8 of an inch I add 5 oz of oil that gets the level at the full mark once again. I would rather add a 1/2 litre of oil at a time. That would still
  16. I'm working on giving it to someone that could use it. It's a stunning dress that obviously cost a lot of money. It has hundreds of shinny bits on it that had to be sewn by hand. Oh! Arbalet was going to send me a replacement exhaust system after a Ukraine Postal service investigation was completed and shipping insurance red tape processed. I e-mailed Arbalet informing them just a few minutes after receiving the exhaust system it was delivered so that process could be stopped. I really happy with the exhaust system. It's really quiet which is what I wanted. The Wife also likes it quiet as we
  17. They’ve already been caught vastly inflating the numbers and that's happening world wide. There's money to be made on a "cure" if they can produce one or even produce a placebo vaccination available just as herd immunity kicks in. Then who's to say the vaccination worked or the herd became naturally immune to the virus as the medical industry makes it's trillions of dollars it shares with the Politicians that require compliance of the Citizens.
  18. Well here's the report of how this worked out. Today a miraculous event occurred. The exhaust system I ordered was delivered today by the postal carrier. When she pulled up in my driveway and honked her horn I went out wondering what she was delivering. As soon as she retrieved the package via the rear loading/unloading door I immediately knew what it was from the shape of the package it was wrapped in. Low and behold it was my exhaust system! When she scanned the bar code so it would be reported delivered she put on one of those WTF faces. She then told me there was an error and that the pack
  19. Got what should have been my new 2 into 1 exhaust system for my Dnepr yesterday. What I got instead was a very expensive, custom made, Wedding dress with accessories. Some of the accessories are 18 karat gold sequins sewn into the dress. The documents that came with the box listed the contents as Vintage Sidecar Parts. "Amy" is going to be a very sad girl! I wonder if she got my exhaust system? I found the Web Site that sold that dress and e-mailed them that I received Amy's dress instead of my exhaust system. I guess I'll find out if Arbalet will fix this problem or if I'm forced to file a co
  20. Check out this video. It might be the answer to your sidecar problem. The 1916 Harley-Davidson With A Twist!
  21. This Virus thing has really messed up everything for everyone. I remember them saying the lock downs would only be a couple or three weeks. At this point I think the politicians are enjoying the extra power they wield just a little too much and are just hanging on in order to attempt to control political outcomes. I'm also pretty sure this will all go away here in the USA after our Nov 3 elections. They've already been caught faking infection numbers by labelling all deaths as being caused by the virus, including one poor guy that died in a motorcycle accident.
  22. If you have a microprocessor controlled electronic ignition unit with the LED for static timing the flywheel must be set at the Top Dead Centre mark. To static time it rotate the unit fully counter clockwise. Then turn on the ignition and rotate the unit clockwise until the LED lights up if not already illuminated. Continue rotating clockwise until the LED just shuts off. The microprocessor unit fires the plugs just as as the LED goes out. It is charging the ignition coil when the LED is illuminated. It's working exactly like opening and closing the points on the old points type ignition syste
  23. That's a very good looking machine! Did you get a sidecar with it? No big deal if you didn't but having one would double the fun.
  24. The ratchet teeth are probably worn down and all it took to finish them off was that last start where the shaft overruns them as soon as it starts but your foot is still on the kick start lever until you take your foot off it. Those teeth do wear a tiny bit every time the engine is started during the time the engine has started and your foot is still holding the kick start lever down. Thankfully Ural and Dnepr gear boxes are dirt simple and easy to work on. Seal and gasket kits are inexpensive too. I don't think the kits come with a new buffer bar, which should be replaced while your in the ge
  25. There's always a first time for everything. All it would cost to check the crankshaft is replacing two head gaskets when reinstalling the heads. While the heads are off the lifters can be pulled and checked and the cam lobes can be inspected as well. Of course the valves need be checked while the heads are off. Something has gone very wrong and the only way to find out what it is to start looking for the problem. Blowing off intake boots is a sure sign of a serious timing issue. The ignition system also needs to be checked. It could be an ignition timing problem where it's firing the spark plu
