Hi marc,the gp crank has a longer and fatter taper on the flywheel end ,you will need to get an nu2205 bearing as well for the mag housing and when fitting this bearing you will need to leave the top shim out as the bearings deaper also you will need to change the flywheel as the gp crank will be too big on the taper.

In my experience if your engines standard I'd stick with what you have if the cranks ok ,you very rarely hear an li/tv magside bearing wearing out due to the short taper on the crank ,hope this helps.

Get A MEC crank you cant go wrong seem reliable.

If it's a genuine TV crank then you'd need to get a replacement crank with a 116 rod to match your TV piston. MEC and other companies do them but I'd imagine that they have the GP200 taper and would need GP flywhhel and magside bearing to match.
If you're not tuning the engine I'd leave it as it is.
