Yup, i know i would need to swap rollers to match the spring. After thinking about it tho i probably wont bother as i would be wasting my time. I remember i tuned my rollers and variator side 1st on my stock rated spring but no matter which weight rollers i used it did not achieve anywhere near the performance i gained from the stiffer rear spring in terms of re-acceleration and going uphills.
For me if i was on a stock rear spring i expect i would need a lot lighter rollers to gain anywhere near my uphill speeds and then with that i expect i would run into issues with losing some top end. The theory is a stiffer spring lets you use heavier rollers to compensate bit that wont work for me, anything over 5.5g, even 5.75g, is too heavy on all stiffness of spring for me, i cant live with crawling up to speed, i want it to get up there quicker.
As i said before, on a stock rated spring i drop to around 20mph up a hill i use to test run on, with all weights of rollers ( in fact on some 7.5g rollers it went under 20mph!!!) . On the same hill with my stiff spring and 5.5g rollers i can blast up the hill at 30-31mph no problem (ok maybe "blast" is not the best description of 30mph but you get my idea).
What i would like to do is have a run on my current set up and note speeds achieved in various conditions, then go back to 100% stock (but still derestricted) and see just how bad it actually feels as stock. I may well do that later in summer if i have some free time to burn.
I reckon once i re-fit my open filter and get my jetting perfect on it i will be running my A50 as best i can without going up to a BBK.
At the end of the day as long as each of us is happy with our own rides then who gives a monkey's? Thats whats so good about the scooter scene, each person can easily and pretty cheaply tune their scooter to what suits their own needs.
