Also went from 2t to 4t about 6 months ago, the 4rt will grip as well as the 2t and sometimes better! just takes a little time to adjust to it.

I've found the 4rt needs a much more aggressive approach, softly soflty doesn't work, if you wind the throttle on and lean back it will find grip

Many thanks to all for useful tips which make sense and I am sure I will be able to apply to my riding without too much trouble. Will check the gearing but as it has new c&s it will have to wait till I've had my money's worth.  

 

Wasn't sure if I was asking a sensible question at first but judging by the high quality of responses, it obviously was.

 

Many thanks again TC members.

Apostasy? Worse than that, I denounced the false prophet. Speaking of profits I noticed a special price on left over Montesa's, same price as a 2 stroke. If they kept to that they might sell more.
