I still haven't discovered the top speed of my ACE, at my elevation, with me in it. Other than that, I've just been riding it normally.
The RPMs naturally get varied during the normal course of riding (I'm not running any races or marathons).
I would avoid towing anything except as a quick test.
Steep climbs? I'd say relatively short ones, no problem. Really long ones? Hopefully you can still vary the RPMs but unless it's like 10 miles of 30 degree climb, I don't see a problem.
Jumps? Catching a bit of air over a sharp hump in the road is one thing, but I've sworn myself off of jumping any machine that weighs more than about 250 lbs. The consequences when things go wrong are too high a price.
break-in is a debatable topic. Some say: ride it like you stole it, others: follow the book.
I've been using my Ace normally..meaning I'm using it. I have run short hard bursts, taken it up some steep hills and have been towing a firewood trailer fairly loaded. The book says not to do any heavy towing til break-in and oil change at 50hrs. Also don't run prolonged constant rpms. Variation is good. No red lines. My oil looks good and the oil level hasn't changed.
I think I'm going to change mine before 50 hrs.
I feel real good about this machine. View attachment 921
Well, for the time being, in my 8 hours / 90 miles of break-in cycle, I have:
1. Avoided WOT for more than a few seconds.
2. Avoided redlining the engine.
3. Not towed anything.
4. Kept my hill climbs short, and used low gear when they were a little longer.
5. Have not jumped it.
6. Have kept my speed below 45 MPH.
Most of that is just due to the terrain I was riding.
Wasn't safe to go faster than that, weren't any really long hill climbs to be found.
Weren't any jumpable scenarios, though I wouldn't have done it anyway.
That being said, front and/or back wheels, probably two at a time, have left the ground occasionally.
Awesome info. I'll be posting up as I get more time in the seat. I wanted to tow my jet ski around my property but nervous doing that till I break it in a little more. We are going trail riding this Saturday so should get good hours.
I just finished the official break in period. I changed the oil at exactly 25 hours and 213 miles. That is an average speed of 8.52 mph for the break in period. I noticed that Scoundrel is having more fun than I am during the break in period. I calculated that he averaged 11.25 mph.
1. I avoided WOT.
2. My top speed was 35 mph, once for a very short period of time.
3. On straight trails I generally hit 25 mph.
4. I never rode for more than an hour at a time.
5. I had several short trips to get the mail.
6. I am a member of the 10-30 club. We ride for 10 minutes and then stop and drink a beverage of choice for 30 minutes.
7. I had lots of tight curves and rough terrain so the suspension has had a workout.
8. I changed the oil at 25 hours and there were metal shavings in the filter.
Metal shavings in the first oil change is normal, and nothing to worry about. Same with little bits of silicone.
That's what the break-in period is all about - the moving parts are rounding off the sharp bits that are leftover from the manufacturing process, and things are "settling in".
That's why you want to take it easy, to let all of the moving parts figure themselves out before you ask the machine for everything it can give you.
That's also why the first oil change is so critical - to get those bits out of the oil so they don't recirculate and cause premature wear. Oil with shavings in it will be a little bit abrasive.
The users manual has that info (I am too lazy to go look at it right now).
Some people are doing the oil change early because they want to. And it's not a bad idea. You can't change the oil too often, especially in the early hours/miles of an engine.
Page 47 of my manual says to change the oil and filter after 25 hours or one month. Page 82 states to change the oil and filter every 100 hours after that. The demand drive and transmission oil is to be changed every 100 hours also.
For the first 3 hours I babied it. Low RPM. No full throttle, varied the RPMs a lot. poked around. Next 20 hours only very brief FT, never over about 20. No towing No flying...well there is this one place if you go off the top of the hill at 20-22 you fly a few inches above the ground as it falls away. Hours 23-24. Longer Full Throttle. perhaps 10 seconds at most once. still not over 25MPH. Oil and filter at 25 Hours per manual. That is where I am now. Now I feel good about hammering it when I get a chance but I have not had that chance yet.
