Wow nice job. But I see you missing that plastic thing under seat. There shoud be battery, and relay holder, air box... Do you know what I mean? this:
Nice job with battery holder and other stuff
Btw. I'm looking on your motorcycle on first page and it looks to me like 634, also with fuel tank, and other stuff. What Only engine is from 638/640. What type is on label on "neck" just behind front light?
Yes, we can buy new from jawa in motoshop here it's not expensive, I will try to buy em here and send to you, if you will not get any in your country. Nice photo try to disassembly it first, drum brakes, especially on Jawa are not very strong. On concrete road I can't lock the wheel also. Only or grass, or something like you.
I meant if there is a better brake manufacturer than jawa original. Like brembo or ferrodo or something like that. But if its normal with weak brakes I can live with it. Just a little worried and perhaps used to dual disc brakes that makes stoppies a piece of cake.
Tomorrow I´m taking my jawa to get it approved for road use. It has been unregistered for the last 6 years. Tested and checked everything so hopefully it will be approved.
Sure it will be approved. Fingers crossed. I'm not sure, if Brembo, Ferrodo, or somethink like these brands are making brakes for JAWA. It's old and not very common motorcycle, only in postsoviet states, some of them were sold to other countries, but not very often. If you once choose JAWA, you must take one thing: it's not bug, it's feature.
And now a carb question. The idle mixture screw is it fuel or air? Fully screwed in makes idle mixture rich or lean?
Also I premix with about 4% two-stroke oil. What do you guys use?
Aaaalso Is engines availeable in the scrap yard over there? I wouldn´t mind getting a spare engine so I could have one ready for use when the one in the bike gives up. Here it seems almost impossible to get an extra engine.
I changed my tyres to something with a little more grip compared to the original. But still pretty useless in mud. Also very low ground clearance so it got stuck under the engine a few times. Well now I know the limits
