Hi, i,m running a ts1 225 with a msc micron exhaust and a 34mil amal powerjet carb , which gearbox and sprocket will give me the best results i,ve got the choice of an italian LI150 box or an SX200 box , thanks

I used to run that setup although mine is only a 200 but used the LI box 16-46 but you can use the SX box with 15-46. Both give 4.8. Or use the LI box with std sprockets but it will probably be undergeared.

Anybody else any ideas please ?

Have you tried the gearbox visualizer spreadsheet?

I am using Li150 and 16/47, 81 link chain, for a 4.99 4th gear ratio.

In the end though, it depends on your type of riding, speed versus quickness, lower end torque/how high your rpms want to be at what speeds.

No i havn,t its all dutch to me that technical stuff , i just want to go at a decent sped on runs etc without revving the knackers off it and still be able to go up hills, or into a wind etc without dropping into 3rd all the time been recommended to put in a indian gp200 box and 19t sprocket but thats confused me even further !

Is your barrel modded at all?

I ran a similar set up a few years ago. 34 mil Amal and a DJ/Micron. I ran 4.6 on it, and it was fine for high speed cruising. It did have a bit of mild porting though.

That would give you the same final gearing as your SX box with standard sprockets or the Li150 box with 16/46

Dont bother getting another gearbox!

I would go for the Li with 16/46 and get one of those over the top chain tensioners and 81 link chain. Then if you want more speed you can put a 17 tooth front sprocket in without buying more bits

That help?

shouldn,t have to bother bother about buying another gearbox as i,ve a couple of spare types , so not bothered about that but i,m gonna wip off the crankcase side and count what sprockets i,ve got in cheers

yes pal mine has been slightly tuned by ralph saxelby ,nothing too serious though

Then 4.8 with the LI box will be fine. He did a bit of work to mine when I had it running with the Micron.
