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.

I think your brother is a very fortunate brother, to have a brother like you!

don-t underestimate the oil coolers, even very small ones have high cooling effect. specially when they come with an internal thermostat valve like mine in the CB650 1983. it was just of the size of 2 cigarete pakages, but strong enough to get rid of any overheating. Even in the Alps, Greece and Turkey never passed 130`C. Normally in summer it did raise fast to 115`C and stay stable between 115 and 120`C
So if I made writing erros its because I am i=here writing in the dark office with sun glasses, because some inteligent maschine operator whipped out a MiniPLCs program and I have to check if the program and the Service laptop still work....
Hurry up Sven, don-t play...
