Re: Newbie looking to buy with questions

You've received some good information so far. Last year I bought a 2010 Gear Up with 20,000 kilometers on it from a guy in California. It had received extensive repairs since when he bought it new. New fuel tank, crankshaft, replaced at least one crack wheel rim, top end twice, transmission just reb...

Re: Neck bearings

Thanks for responding Jeffsaline, I have a mig. Cutting would be last resort MIG will work well. Just don't weld the race to the steering head. Some guys make three short welds spaced around the inside of the race. I usually make one long weld of maybe 2/3rds of the inside of the race. If you have ...

Re: Neck bearings

If you have a welder you could weld a bead to the inside of the race and when the weld cools (about 45 seconds) it will shrink and the race will come out easily. You could also weld a washer to the race so you have something to pound on. If worse comes to worse you can cut a slot in the race with a ...

Re: Loses speed when I throttle up

When people shim needles it is just to change the position of the needle in relation to the slide. Moving the needle higher allows more fuel sooner. The shim(s) just need to fit around the needle and the needle will hold the shim(s) in place.

Best,

Jeff

Re: Loses speed when I throttle up

This was quoted from Jeff but I somehow erased that part. "As I was reading your description of yesterday's performance I was thinking if I was working on this I would be pulling the carb tops and inspecting the slides and diaphragms (and making sure the slides move freely in the carb body bore) an...

Re: New battery time?

Lew, Maybe put a voltmeter on the battery and watch it when you first start the machine. Then when you go for the second try put the voltmeter on again and see what you get for a voltage reading while pressing the starter button. I'd want to see 10.0 volts or better all the time. My guess is the vol...

Re: New battery time?

If I was evaluating your battery I'd want to know the voltage with the battery at rest, with the key on and the headlight on and finally what it reads when cranking the engine for 15 seconds. Voltages I'd want to see are 12.5 or better at rest, 12.3 or better with the key on and headlight on and at ...

Re: Running Great Since I bought it. Now...

My guess is the left carb pilot jet is restricted. Easy fix since that carb is hanging out where you can easily get to the bottom of it. All you have to do is drop the float bowl. Then remove the pilot jet and inspect first and then clean. Replace the pilot jet and reinstall the float bowl. Probably...

Re: Pretty near stumped

This can be done and is easy to do. Have done it many times on aircraft engines while timing them (different overall method, but it easily finds close to TDC for timing). It will be close enough to tell if the flywheel is off and that your timing to the proper mark. Remove the spark plug, place thu...

Re: Both Carbs to petcock vacuum?

It makes sense to use the left carb since that is the side of the tank the petcock is on. Connecting to both carbs will not increase the vacuum. On some twin cylinder bikes there is a vacuum line connecting the intake tracts. As I recall it is supposed to smooth vacuum pulses. In my opinion it is an...

Re: Bad things happened. Bike is a large paperweight at the moment. Someone tell me where to start.

My guess is you will have to go through the entire engine to determine all the damage. Probably bearings as a minimum and possibly a crankshaft and maybe a top end will be involved. It will probably be expensive.

Bummer, sorry,

Jeff

Re: Pretty near stumped

I'm not familar enough with the Ural engine to know how the flywheel is attached to the crank. But I have had bikes (BMW airheads) with the flywheel incorrectly positioned on the crank. That was with a five bolt pattern. The fix was to correctly position the flywheel on the crank. I've also seen fly...

Re: Yet another mirror thread

I think bar end mirrors on my Gear Up would touch the sidecar windshield in some portion of bar movement.

Re: Loses speed when I throttle up

Thanks for all this advice. I will check with mechanic about gravity flow fuel filter and screen. I will watch a YouTube and learn how to drain carb bowls (do I drain both?) Rode yesterday and today. When she starts up, no power at all unless I rev up the motor for 20 seconds or so. Also tends to l...

You could always tap out the holes to the next UNC or UNF size, whichever is closest to the original thread.
Might be worth keeping the threads metric. A heli-coil could be a good permanent fix. It would be really easy to do well with the flywheel off.

Best,

Jeff
