You will find here topics about home made maintenance and repairs of older cars and motorcycles. For example (2000) Peugeot 306 HDi, (2005) Mitsubishi Colt 1.1, (1992) Jawa 350/639, (2000) Suzuki GSF 1200 Bandit and others. Some advice and test videos maybe too, we'll see :)
Just a heads up,did you notice the arc across number three possibly three and four plug leads to the head gasket breather,approximately 5.56 timestamp. Didnt seem to effect the running of the bike tho.
Must say that originally not, as I was focused on the setup...now as you mention it, yes there was an arc, which is not good. Must think about changing the leads. Occasional missfiring does not have much effect on the engine behaviour - it looks like it. I tested the motorbike for top speed and the cylinder is working.
@@REBUILDLab I have an 99 1200,carbs balanced,AF ok. problem,on slow deceleration(even at 40mph)worse the slower it gets,revs off,bike has a judder/jerky issue,not enjoyable to ride,any idea the cause?
Still an AF problem if spark is good, I think. Is it doing that at still stand too on a free decelaration? I would pin a small diameter transparent hose to the carb drainage outlet and watch what the fuel level height is doing. If the engine idles good, then the idle jet should be ok. Then a clogged carb bypass to higher loads could cause this eventually, you could see that bypass in the drawing on the video. The engine doesn't receive enogh fuel mixture or receives wrong mixture... That's what I think at least...
Props for showing that its not always just clean them and it runs great. I've had mine off 3 times before I got it running right, a/f still needs some fettling at tickover.
Yes, it's not that easy. I had to set the air fiel mixture after all this was done, to get the bike running right. Of course, because it was all disassembled...
As a mechanic, I couldn't work right with those big gloves!!! I prefer to wash my hands with godd hand cleaner..... Well I guess there are different ways of doing things....
Well, I work with gloves because the oil products like to go through the skin like everything else does and that's not something I'm comfortable with... So for health reasons.
Just try this one and you'll speak differently. It is another bike. You do not consume power to spin the heavy crank, you have the power on the wheel! 👍
@@REBUILDLab it would be easier and cheaper to just buy a Yamaha RD350😁 I was installing new pistons and rings in one of my Jawas and got out my Dremel to do some port adjusting like I did on my old formula one Suzuki 750 triple two-stroke when I thought to myself "you are going to change the ports on a bike with a 10:1 compression and which doesn't even have an automatic advance and retard ignition system? Don't be stupid and waste your time".
How much costs the RD 350? The problem is I like the Jawa...it has been in the family more than 20 years. Slowly I will get to it probably and do some more things to it, we'll see. Anyway, with this crank it is a while new motorbike, the engine is so elastic, can't believe it. Even if everything else is stock...
@@REBUILDLab An RD 350 in reasonable condition costs the same as a brand new Jawa 350 two stroke. I keep riding my sidecar TS my Red Style and my TS converted to a cafe racer😀
@@andrewallen9993 Thnx for the pricing, did not knew that. I am thinking of cafe racer style mod on my Jawa too, but have to do the GS 500 wrecked engine first :)
I had to do the cleaning job this year again and found out, that the suction port clamps must be loosen much much more, so that they can deform a bit allowing the carbs slight in more easily. With only little loosen clamps it is impossible to press the carbs in.
It depends on what kind of gasoline you will left in the carbs during the winter. If there is bio gasoline, expect to have clogged carbs in the spring. I would use 98- 100 octane gasoline with low bio component in there for the winter plus gasoline stabiliser. Should be better then...
Hey man, finally someone who does this, this is a great video and you should definitely keep doing them, last saturday i had a lil crash and i enden up blowing my whole pulse generator, i ordered a new one but i think theres a bolt stuck inside, i can show you the pics to make sure, im trying to do it by myself bc its my first bike and i really like her, also ive been putting a lot of love on her, if you can help me that would be really awesome, thanks in advance!!!!
Thank you. It is a thermometer from the oldtimer Skoda 120L which means sensor and gauge. The sensor is sitting on a small beam, that is connected via cylinder head nuts to both of the cylinder heads.
Note about the torque wrench, when it clicks once you don't need to make it click a 2nd time since the 1st click already set ti to the required Nm. 2nd click basically does nothing. Fantastic video!
If there is no vacuum, then you have a leak. The crank halves went not together, leak between the two crank halves, carb path leak somewhere, leak under the cylinders, or sealings of the bearings... where ever you look that something went together, is a possible leak. You have to go one after another and inspect. It is difficult to say what is bad just like that. But if you are sure the vacuum is the problem, then at least uou have a point where to start.
Hello, if you are sure that it is a vacuum problem, you have to start looking at every connection between crank, that there is. Bearing sealings, crank halves, carb to crankcase etc. But start from the easiest thisgs, do not thing the most complicated it shall be. Good luck
This is good, except one fact - the new oil filter is dry. Once you start the engine and let it running, turn it off, let is cool down and then fill missing oil that now is in the new filter.
There is no such one, I didn't think it was necessary at the time 😀 Anyway, the carbs are clogged and dirty again because of the bio part on the gasoline (10% here) so I have to do a quick clean again and then it cab be with a start of course.
I have this same bike that I bought last year with 17000 miles. Sweet engine and I love the bike. Definitely worth fixing. Your videos are extremely educational. Thanks!
