All 2st Fuel/oilmix for street use?

Hi guys,

I realise this thread is a little old but i'm new on here and i cant find much info on 'tarded 300's anywhere on the net.
I've just bought a second hand "kit" from a SMR510 to fit to my WR300.
The "kit" included triple clamps, forks, wheels and front brake assembly.

I measured as much as I could and seems as though it should all go on fine, but is there anything I should know about in this conversion that might be of a concern.

Cheers!
