Maybe engine gurus like Dennis can confirm this but I read somewhere that you can lower the tank so much to a point when it is lower than the engine carb, then problems with the fuel not being able to be picked up by the carb will arrise. This means engine problems !!
No doubt the engine mounts will be lowered about 2 mm on the 710 when compared to the 705 while at most, the same tank can only be lowered about 1 mm when compared to the same tank that is mounted on the 705, judging from the fact that a 4 mm chassis is used on the 710. My 2 cents.
