even the esteem, zen, contessa, ambassador 1.8, 118 ne, pretty much all cars that have ever had a carburettor post 90's have had only mikunis.

So the jets are very much available you just didnt look in the right place. even when i went to bike spare parts shop they had no jets , but going to a car spare parts dealer solved that.
I wouldn't mind being wrong a thousand times over if there's something to learn involved . And inputs like yours here are what we are looking for. Since this is a thread related specifically to ZMA and ZMA-R 'Altitude issues', it would be great if you could give specific inputs about parts from which carb can be used on the ZMA carb to alleviate this mixture enrichment issue. There usually are innumerable examples of parts commonality amongst machinery but reinventing the wheel wouldn't be wise if someone like you has already done it.

And yes, by and by the ZMA comes with a Kehlin CV carburetor and getting parts support for kehlin's in India has been a pain all along. Mikuni and Kehlin jets are quite different and their flow characteristics do not go well with Kehlin carbs apart from differences in thread pitch. The Mikuni's even come marked differently, their round head jets being marked according to the hole size in microns and the hexagon heads being stamped with flow/unit time. The Pulsars, Bullets, Marutis and NE's all have Mikuni's and so interchangeability is possible. Like I said, please let the forum know which jet from what carb can be a direct fit for the ZMA here.

Shreeni: if people use ZMA jets on the Unicorn, then there's no reason why they shouldn't fit the other way round. Again, sourcing carburettor parts for kehlin carbs is a real pain. Ask those who've tried upjetting the ZMA. But the 115 from the unicorn should sort out the problem as the ZMA comes with a 125 main as stock.
