Back pedalling! I love the way you argue Globs! Interestingly due to it's design Spaceprobes 600 engine is likely to be a better candidate for motoman, but still wouldn't recommend it.

Motoman is very different to the book method in the way it affects the engine and the running in processes. It's in effect an extreme version of the book method which of course at no time tells you to use full throttle in the early stages of running in due to the detrimental effects it can have. Motoman tries to hurry the process and in doing so interferes with physical and chemical changes to the components preventing the full process from happening. And thats what the metallurgists found in our engines. I suspect you don't understand the running in process in engineering terms and are blinded by the internet excitment about doing it differently without being aware of the longer term possible consequences. It would be interesting to hear your views on the method when your engine has aged further with 30+ k's on the clock. It may still be ok but like many who have tried motoman now, you may be singing a different song. But irev is right about being careful concerning warranty. Techs and the manufacturers can tell how you have treated your engine during running in so problems often won't be covered. So anyone considering doing this might like to bear that in mind.

I think one of the joys of this forum is the way threads go off course and in the process one gains lots of information (mines a G&T Data). Of course in the absence of any other review what we all want to know is how much vibration there will be from this big thumper, pen is poised.

G & T's will be lined up and ready spaceprobe. I'm afraid I have that disease that Bluebottle often mentions, you know, lengthy posts. I can't wait to hear your initial reports on your bike though. I suspect you will be pleasantly surprised at how smooth it is, and not unlike you 400 in that respect. I'm genuinely getting excited for you...and me too as I want to take one out for a test spin when one is available. May end up taking the plunge myself as I said.

What's the latest ETA on your bike now Spaceprobe?

Ship due to dock Southampton 8th April and SYM are talking to dealer about the 12th. Dealer and I feel that may be wishful thinking so I am working on towards end of April (in time for my retirement). Data you will be welcome for a spin on mine if you can't find a demo.

Mid April, I may be picking my X10 up around then so it'll be interesting to compare the good and bad points! Still not sure which SYM it should replace, probably the GTS300 as that is the most similar.


Data, I'm not sure how you applied the motoman method to your test engine but it sounds to me like you were doing it wrong. As we are in the maxi-scooter world of large engines and CVT/auto drive I'm also puzzled about how anyone could possibly transmit continuous large forces and therefore undesirable heat to the engine?!

Having run in 2 scooters as close to the motoman method as possible (speedup, slow down, repeat for 20 minutes, change the oil) I can tell you from personal experience that when you twist the throttle on even a 171cc machine it leaps forward and very shortly afterwards you need to twist it back again until it's going slowly enough to do it again quite a little while later as engine braking on a CVT is not great. It takes a deserted road to even try that properly.

So quite how Data thinks anyone is going to get even close to over-stressing their new max-scoot engine is beyond me. This is not a test engine on a bench strapped to a dyno, this is in a light weight machine with an auto gearbox. If you open the throttle with 600cc behind you I can guarantee you will be going faster than you want to in very few seconds.

It's a topic that will run and run, but suffice it to say that I haven't found any real world story that has had problems with this method but I find plenty that have problems after the 'book' run in method. e.g (one of many threads: http://www.advrider.com/forums/showthread.php?t=120623" onclick="window.open(this.href);return false; ).
We'll always have the Data viewpoint but it's important to remember that our engines are in bikes that move.

May I chip in?

What an interesting thread on two maybe three counts! Firstly, Ive certainly learned something after all these years regarding running in; I'm in the handbook camp and have always run my engines in gently but keeping the rpms varied. I have never changed the oil out, however, after the initial 30 miles or so, just plain ignorance on my part but I will remember this!

Like the others here I'm very interested - perhaps a little excited - in Spaceprobe's thoughts on and the idea of a new maxiscoot competing with the established big scoots. So, keep the thread going on-topic and off please, with a few photos of Maxsym 600 scoot and new owner, sitting on said scoot, thrown in!

Thirdly?............err thanks for allowing me to chip in

Ooh, I'm now editing this..... in light of reading Globs' last post.......here goes......

Spaceprobe, just ride your bike as you normally do and I'm sure you won't have problems with your new bike...

Well an update on my parts issue! Got a call today from my dealer my panels are here! Happy days ! Hopefully the correct bits. Get them replaced at the weekend. So scooter will be ready for trade in. Not heard from dealer about my Joymax yet, but hopefully around the dates Spaceprobe quoted. Buying if from a different dealer than the one I'm getting parts from. Looking forward to new machine! Looking forward to your pics Spaceprobe.

Excellent news on your parts arriving (at last). So when is your new bike arriving? I take it you're definitely going to stick with SYM now?
