Thanks for all that input from the experts - "the general recommendation for running in is no more than 3/4 throttle and 85% top speed, then leaving the restrictors in certainly helps the rider from being naturally exuberant." my thinking (and the reason I opted to remove the restrictions at just 230kms was that in order to get anything OTHER than 100% throttle during the running in period and 85% of top speed (if top speed is only 50km/h) this would be about 2/3rds of a snails pace around 40km/h.... and
a) I felt incredibly vulnerable/unsafe going that slow
b) that I was doing the new engine no favours at 50 km/h and max revs ....
So by getting the derestriction done sooner than later I reckon it's a win/win/win -
- I win coz I feel safer being able to keep up with traffic at 60km/h -
- The scoot wins coz I now have a reasonable range of revs and speeds (instead of FLAT OUT and STOPPED) and
- the Cage drivers win ... coz I aint holding them up and getting them cranky at 50km/h.
Frankly I reckon the main reason the guy I bought the scoot from sold it so cheap with such few k's on it was coz he said he felt "monstered" going down Wanneroo Rd in morning traffic ... and yet if he'd NOT listened to his mechanic (the one that told me to wait until 500km) he probably would have been enjoying his scoot instead of DREADING it !!
You make some valid points, but I'd request you try and see the bigger picture.
The main reason that many scooter riders (particularly in places like WA) feel "monstered" is because they buy the wrong scooter for the job. It would be much more appropriate (and it would have been our recommendation) to ride a 125cc scooter on roads like Wanneroo Road than any 50cc, vanilla, derestricted or modified. But too many people don't have the time or the inclination to get the license. Its a sad fact, but its true.
For 16 year old riders who don't have the option, we have found that a few weeks of restricted use generally bodes well for their long-term safety. Yes, it is safer to be able to keep up with traffic, but most novice riders (of any age) would benefit getting a few kms on the clock at a max of 50kmh before taking it up to higher speeds.
Furthermore it is still illegal to take the restrictors out. Doing so could invoke a significant fine, and potentially for the dealer an awful lot more, particularly for new vehicles. If, after a few weeks of ownership, a customer understanding the legal situation decides for safety reasons that he would like the restrictors removed, then that is their decision, not ours. By taking the vehicle outside of ADR compliance, you are potentially invalidating insurance, CTP and other legal matters. Its not a decision that should necessarily be taken lightly.
Saying that we think that the 50kmh rule is ridiculous, and unsafe, but we don't set the legislation and we are most vulnerable to its abuse. Unfortunately if derestricted scooters became a big issue, then don't be surprised if the licensing legislation changes and we in WA will no longer have the ability to ride them on our car licenses. As far as most car drivers are concerned (and most bike riders too), 50cc scooters IN ANY FORM are too slow and dangerous and shouldn't be allowed on the roads.
From a technical perspective, these engines are not designed restricted. They are designed unrestricted, and then the artificial restrictions put in. So, yes, they should (and do) run better without them. The question is, during the running in period, would leaving the resrictors in help a rider to keep the vehicle within the recommended parameters? In most cases we think it would, but at the end of the day its the customers choice. Once the vehicle belongs to them, what the customer has done with it is their responsiblity and they can go with any recommendation that they choose. If they want it done at 50km, then that is up to them.
