3 days waiting in a 120mile trafic jam. As long as the gulash cannon is smoking not too bad...
Sven
Eeee.. Jawa 350 drinking only 3.3l/100km? Tell me more about this vechicle AFAIK 5l/100km solo is normal
What may be different to others?
mufflers standard but with better home made packings (Gylon = foamed teflon)
In the carburator we changed after 2000km to smaller jets.
NGK spark plugs and NGK plugs for the spark plugs, I will have to look up which type when I get to the shop as well as the jet sizes.
Sidecar relation for the sprokets, so gears are pretty short.
Riding style allways running free not presurized. means above 2800 revs to 4500 revs
The carburator was tending to get stuck, so I scraped and stoned it with prussian blue each time it started to get stuck until it finished its deformation time (remember the aluminium will not stay in form until it aged as we know it from tool machine's grey cast.)
Same with the throttle distributor.
In the carburator the second needle for the mixture at the front. I never used it in the original position of 1,5 turns because then the engine would run too dry and hot.
I used to fine tune by riding in low revs feeling the torque curve. In the original set up it would start to have force over 3700 revs. By opening the mixture needle 1/16 turn 22° at a time i searched the point where the torque curve would start at 2000 revs (and would become again slow at 5500 revs).
Normally that point was at 2,2 to 2,75 turns.
As the engine starts to vibrate above 4200 revs and there is no spark advance, fiddleing at high revs was never an option for me.
NEVER change the 2 stroker oil brand. In the beginning I used Castrol supper TT, but that sucks.
Since I canged to Husquarna 2 stroker blue chain saw oil I became confident.
Oil pump some 1,5 - 2 mm more throttle in minimum then normal because of the sidecar, but so that the smoke is even at steep hills decent but never absent.
In between the cylinders I installed the temperature sensor of my 1982 CB650 and tried never to drive over 150°C head temperature for more then 5 minutes.
Beside smooth running in after each rebuild without sidecar for 3000km I did not do any thing else special to her.
No wait!!! For 20.000km I had 2 computer fans mounted above the cylinder heads, but they were too week (see photos in the album section) A good fan I never found
The control starts in the driver's head and keeps the throttle hand in its limits to never put full throttle more then 5 minutes.
I guess that is all.

First 2 strokes of 1950 vintage specified 16:1 ratio of gasoline to oil mixture, then later 20:1 in late 1950's. Lots of plug fouling but run forever. Engine materials and designs improved so 32:1 became standard from the mid to late 1960's. In the recent years oils supposedly improved dramatically so new specs of 40:1 in the 1990's were common, then finally 50:1 gas/oil is specified by many mfgr's, most with a suggestion or demand to use only their own mfgr. brand of 'Miracle Oil' at 2 to 3 times the usual price.
Far as I can see the mfgr's had years of research and experience that showed the large majority of 2 stroke engines could survive through the 1 year - 2 year warranty period at these mixtures but not much more. That was fine because most people have a tendency to replace a machine with something very similar, in brand loyalty and force of habit, if not dim wits. This keeps sales robust and strong.
I still use 32:1 with premium oil in every 2 stroke regardless of any suggestions or mfgr's specification. The tolerances never changed, materials never changed much after the early 1980's [32:1] so why fall for the story line that they will be just fine with LESS LUBRICATION??
My 32:1 2 strokes sure outlast any of my friend's or other's 50:1 ratio engines and that's enough proof for me! 2 strokes when properly tuned and maintained run just fine with minimal plug fouling and without excess smoke at those 32:1 ratios. Seems sort of strange to be on a quest to save the tress and the environment by specifying 50:1 smoke-free oil/gas ratio....for chain saws or dirt bikes!???

In pre ethanol days regular gasoliine had better lubrication properties than ethylene gas.
The current 10% minimum ethanol gas we have now has to have less of these properties than the earlier fuels.
With the new 15% ethanol mandate due to kick in soon here in the US I'm all for adding more oil in the 2 stroke engines, whether weedeaters, chainsaws or motorcycles.
Lonnie
Gasoline mixed with ethanol? It's very dry. If i had to fill my tank with such magic mixture, I would add oil even to 4 stroke.
Is it mandatory in USA? Don't understand why, mayme someone can explain. Production of ethanol consumes more energy than ethanol can give burnt... And addition of ethanol can cause rust in some parts of engine (nor like pure ethanol). And engine needs way richer ethanol-air mixture to survive than gasoline-air.
Ah, but you are making a classic mistake, Igor! You are applying common sense, good engineering, logic thought, simple deductions and well documented scientific proofs to the subject of wide-eyed, hysterical, rabid dogs foaming at the mouth ultra-ecology! The two cannot coexist.
In addition ethanol completely trashes anything rubber and many synthetics in the fuel system. It also steals a food crop, corn, and drives up the price of corn. Higher price of corn and corn by-products such as corn oil drives up the price of other foods and commodities. In addition it's not cost effective overall. The fact that it is totally inefficient and causes vehicles to get much worse mileage in addition to causing damages which raise pollution levels is also ignored.
Currently ethanol additive is at 10%, but the new mandate is for 15%, which will do severe engine damage on most older vehicles. In addition, ethanol alcohol absorbs water to at least 50% of its volume, which means 15% ethanol plus 7.5-8% water in all gasoline formulas. Water normally evaporates from gasoline fuel systems but ethanol reverses that and draws water.
These maniacs will never be happy until we are back to walking barefoot or riding bicycles.
I believe in sensible, well reasoned, practial and effective ecological plans as opposed to sheer idiocy.
Sorry, that may be difficult with a translator if you use one.

Jimmie, You start to speak as harsh as I do...
The greens during Mr Schröders government in Germany made things as foolish as You describe with lead in electronics. Eletronic components that were comon for decades disapeared from the market. Now try to repair old equipment => throw away. => what is more energy and resource consuming?
Or Costa Rica 1989: There came out a investigation, that diesel smoke is provoking cancer.
12 days later our health minister Edgar Moos (who in fact is an excellent medic) came to the brilliant idea to prohibit the importation of ALL diesel vehicles...
Die Schildbürger sind wieder los. The citizens of Gotham are left free to make nonsence.
It might sound strange, but my 1-3 man company is called "tecnology for environment and devellopment" and I am bussy working on it, but there happens so much foolishness in the world that there is no way to implant the only needed improvement for mankind:
Common Sence!
Sven
Until common sense is again common and not affected by those with capitol gain as their main objective we will see little to no improvement in the present situation. I am fearful that there are just too many brainwashed folks out there today pulling too many strings prompted by thoughts that they are actually doing good that the chances of a turn around to sane thinking anytime soon is questionable. Good example: Google HHO sometime and do soem research on hydrogyn power...the guy named Myers ( I forget his first name) did some great things but there were many efforts made to sweep it under the rug. So it goes..Th eworld system is
all about money being put in the pockets of a few at the expense of many.
It's all manipulation, that's for sure. I've been told that somebody unknown to me crunched the numbers on the world's actual true wealth, natural resource value and financial holdings total amount and that if distributed equally it is enough to make every adult alive as of about 2005 a BILLIONAIRE!
At least in Costa Rica, where we change 503Colones per dolar it would be easy. My KLR650 was 4,5 millon Colones and they passes the coun ter in a finger snip.
Everything is relative and in share trading You notice daily that everything is manipulated to the extreme, that real bussines isn't reflected at all in wall street.
A nephew works for economic investigation. Although today in Costa Rica Intel exports 25% in Cips of total country exports, the PIB per capita was higher in 1974 then today...
The so called development here looks like eye washing... That something goes wrong I noticed the day I met a BMW M3 on the street in....1992 or 93.
On the same crossing today pass possibly about 45.000 vehicles in those times 3-4000 a day. Means stop and go arround the clock (ahh, You walk faster).

Latest news. We loaded some "permanent load" on the bike. Two heavy 25mm-thick plates, 8.5kg steel one and 13kg Pb, both painted and screwed under the floor.
Yesterday we had -7*C temperature and rain afternoon. My brother's workmates laughed at him "You will not leave the parkplace on your 'creature', may I pickup You to home?". But in the evening, the bike required only to brake the ice-couverture in few places, two kicks in kickstarter and brother left the parkplace before they deiced their windshields and burgled to their cars.
Hello Igor,
what kind of engine is it? It looks to me like a copy of the Honda Supercup 4 stroker with semiautomatic gear box.
With the cold wheather it would be good to go down with viscosity of the oil. Albeight the small engines heat up much faster then the big ones, the engine in winter doesn't come to good operation temperature. That is the main reason why many winter bikes will have low engine performance in spring.
Specially BMW and Guzzi are very unwilling to start in ice, You have to put a stove below the engine for 30 minutes before they even would crank.
For sure the moped will be an excellent winter transportation, much more reliable then many cars.
And most of all GOOD FUN.
Sven
This engine is Honda Cub, Chinese copy, full manual 4 gears. Without additional oil-cooler (very popular) it shouldn't work in summer, because radiators on cylinder and head are much smaller than in original. So in winter it runs perfectly when one disconnects or isolates the cooler. We wrapped the cooler with cloth and some foil.
Moped is ideal for my brother - not too fast but allows to learn first sidecar rules. It consumes 1.7-2.3l/100km solo and about 2.8-3l/100km with car.
That the consume raise so much indicates 2 things to me: First he loves to use full gas. Second as bigger the engine as less stress for it to pull additional load. Or other way round, as in his case. the smaller the engine the more it has to work and suffer when You add a sidecar.
Your brother's consume added something between 30 and 64%.
Funny is that with the Jawa (with original engine) I see a plus of average 27% = 3,3l/100km =>4,2l/100km
I forgot the numbers but people with bigger engines tell here something like an additional consume of around 20%.
I am interested how the Husquarna engine will work out...It will be a raise from 29 to 48hp plus the change from aircooled 2 stroker with 4 shifts to water cooled 4 stroker with 6 gears.
By the way the italian Husquarna 450 is a VERY strange internal engine design... That are no pistons any more, but barely ashtrays.
