Scott K-750 Posted November 30, 2009 Report Share Posted November 30, 2009 Hello to the brains trust. Well things are progressing with my education on my K-750, I have read so much and absorbed so much over the past few weeks my head hurts. I do have a few questions I hope someone can help me with; 1. My carbs are PZ-28D. What size jets should I use keeping in mind I am in Australia? I understand different sizes are used above or below the equator (?) 2. What is the correct point’s clearance? 3. What is the correct head tension? 4. Does any body know where I can find, read, beg borrow or steal a manual on these types of things or is it just a case of “Its not written down, just ask” The education continues….. I thankyou all in advance, Cheers Scott Quote Link to comment Share on other sites More sharing options...
Serious Black Posted December 1, 2009 Report Share Posted December 1, 2009 #98 DellOrto 5mm main jet worked for me. A Keihin jet of similar size should work. Point clearance is 0.5mm. Head torque Cyl. Heads 29-33 Nm 21.4-24.4 ft.lbs For a manual Chang Jiang will do for the engine/gearbox and one for a Dnepr for most other things. Just ask if your not sure.

gspell68 Posted December 2, 2009 Report Share Posted December 2, 2009 I've been all the way to the end of the internet and there's no free English K-750 stuff on the web. I know it's not a K-750 manual, but most of the mechanical stuff still applies, it's Curt Peredina's Ural M-72 manual. It's an English translation of the German translation of the Russian copy of the original German BMW R-71 manual. http://www.cj750.net/sitepics/faqhtml/Manual_M72_English.pdf Quote Link to comment Share on other sites More sharing options...

Sounds like an SAP computer manual - written in German by a Hungarian and translated into English by a Frenchman. Peter Quote Link to comment Share on other sites More sharing options...
avalon Posted December 2, 2009 Report Share Posted December 2, 2009 Why different jet sizes below the equator? I'm running OK on northern hemisphere jets. Quote Link to comment Share on other sites More sharing options...

Scott K-750 Posted December 2, 2009 Author Report Share Posted December 2, 2009 Why different jet sizes below the equator? I'm running OK on northern hemisphere jets. Wasn't to sure about different jet sizes in different locations, just something I had heard, something to do with differing fuel qualities and atmospheric pressures? Can anyone confirm?

gspell68 Posted December 4, 2009 Report Share Posted December 4, 2009 You are correct to some extent. Sometimes at higher elevations you have to advance the ignition and maybe change the jets.Usually, raising or dropping the needle should fix most problems.
