Anyone running this gearbox or had any experiance of it thanks

If it's the same as my Indian 150 gearbox that's sitting on the shelf (same 1st 3 gears as a gp125/200) then it's got a big gap between 3rd and 4th, I struggled to get a workable ratio using it so swapped it out for an Indian 200 gearbox.

Its a GP150 Indian Vijai Super,it has a different 3rd gear from the GP150/SX150 and reduces the 3rd to 4th gear gap.I run the same gearbox in my series 2 with 18x47 sprockets and a Casa 185 top end.I'm currently building a Casa 210 with the same gearbox and sprockets,this will be going in my series 3 scooter.

I think I have one of these on the shelf.

Although the gap from 3rd to 4th is smaller than a traditional GP150 box, the gap from 2nd to 3rd is huge (33%??).

I need to check this, but then you can do the maths now you have the numbers of teeth.

Its the same as the Indian GP200.

Thanks for replying

as above answers realy, its more or less the same as an indian gp200 with a slighty shorter 4th gear very useable with the correct sprockets, not to be confused with the later mk2 version which is a shocker of a gearbox with big jumps between the gears.

Thanks holty

Its the same as the Indian GP200.

Just to confirm this is an Indian 150 box,although some 200cc scooters/engines were imported in the late 90's with this fitted as the factory/supplies/production reduced.
The correct Indian GP 200 cluster is 10-12-16-18 and has the closest ratio between 3rd and 4th.

I was answering Knowledge where he says "the gap from second to third is huge"
