running an SX200 gearbox with 46t crownwheel 16t front sprocket, 4.5 ratio on a TS1 with JL3 pipe

If they arent...I think they should be. With engine set up to suit..... ;o)

Did that exact set up for years. Pulled great with loads of go in all the gears. I was using Taffspeed MK3 exhaust so basically the same thing with a TM35 Mikuni. Probably the best motor I ever ran.

Thanks

Currently using an LI 150 Italian box which is 4.8 ratio using same crownwheel and front sprocket. Have acquired an SX200 box and was wondering whether to put that in, but was unsure if it would be too tall to pull
