Default how far have you gotten??

without your MB breaking????
(and what broke when something did break?)
1. 1-100miles
2.101-250 miles
3.250-500 miles
4.500+ miles
5.none of the above, I took my bike out of service to mess with/upgrade ....

Also: who has gotten the highest miles without messin with it (the MB)?

Just curious, cause I cant seem to get around the block before I have to mess/tinker with something, and I'd really like to commute with this thing someday.

Thanks

HI

First build got me about 3 miles before I had to stop....The engine mounts loosened up and engine was on the verge of falling off....

After this was taken care of, I rode another 2 or 3 miles and then saw the chain had Waaaaaayyyyy too much play in it...Had to limp back home and take care of that...

Once these two issues were taken care of the bike has been pretty reliable since (but at about 60 miles I had to retorque the head bolts)..

Hope this helps.

Andrew

Andrew, You arent talking about your trek are you?

Seems like most MB will have some breaking in issues (like a misaligned sprocket or something). Once that stuff is fixed.... well how does it do?!??!?

Default Re: how far have you gotten??

Five years ago when I first starting riding my motorized bicycle it was about thirty miles when I decided to change my chain. I was having to adjust it on every ride.

I commuted to work everyday for five years and three months. (too far to commute today)

Two years ago my throttle cable broke on a very long ride.

This summer on my fifth year and well over 4,000 miles is when I started having trouble. First, I had to replace my rear wheel due to breaking spokes on almost every ride.

Second, my rear mount broke...hmmmm...thats it.

I'm using the same studs...same gaskets...same no bearing chain tensioner. I ran the stock plug and wire for over four years and with no fuel filter. My kill switch lasted three 1/2 years before it fell apart. And I never installed the stock clutch lever just used a brake lever. Still using the stock clutch cable. And I've never had to adjust my clutch.

The only real problems I have had is from my own fault. Like I forgot to tighten my tensioner one time and it got into my spokes. I always seem to forget to bolt my brake arm for my coaster brake and you know what happens when you go to use the brake

So I've had a bent rear sprocket for almost a year now and no chain problems what so ever.

So five years and some 4,400 miles...Chain, kill switch, rear mount, rear wheel, and a throttle cable.

Only once I had to pedal home and that was when my tensioner fell off. Even when my throttle cable broke I still managed to reach my destination with a little road side fix.

Oh, and I have had three flats two in the last couple months.

I also lost my rear brakes comming down a Mountain and almost hit head on to uncomming traffic when I was going to fast to make a turn...I now have front brakes but mostly to make everybody on the forum feel better I like to live on the edge

At 700 miles, my clutch pads were worn down so far I had to replace them. Put in new pads and I quit climbing the mountain passes with the 36T and have racked up 3,500 miles since then. Same clutch pads. I lubed my clutch bolts and changed my springs to 45's when I replaced my clutch pads. Total down time 20 mins. I decided I would have to put on a larger sprocket if I ever decide to climb the mountain passes again. Changed the oil 2000 miles ago.Replaced both primary and secondary chains around 300 miles ago when I installed a 41T. I did not need to replace the long chain but the Gear box chain was stretched so I replaced it. ...That is it for my Titan..

The other problems have been the bicycle. Broken spokes at 300 miles and replaced the rear wheel with a Diamondback 36 spoke wheel and that fixed the spokes problem. Several flat tires which stopped with thorn resistant tube and then lined with 2 old tubes total of 3 tubes in each tire. No more Flats !!! O yes.. A rear brake shoe that wore down to a metal piece and this metal piece dug into my alloy rim !! Yikes !! I replaced the one pad and had to hand sand that side of the rim to make it smooth again. So.. Now I am looking for 4000 plus miles.. Today it was 64 degrees and beautiful.. The next week is going cold.. Looks like my 4000 miles will happen in spring.. I will get some fenders so I can do some Slush Snow weather riding.. Enjoy the ride...

I've got the same problem, but I think that is the norm with these engines, from all that I've read. I think that once the bugs are worked out they'll just go and go. Mine seems to be running good and strong finally and all I can say is, "It's about time!"

I think one trick of keeping it going longer is to keep the R's at mid-range, but I'm no expert. Everytime I had run full throttle, ripping up the neighborhood, for hours on end is when I seemed to attract problems with this engine. Now it's snowing everyday and I have to run slower to keep from wiping out on the ice and my MB has no problems whatsoever, outside the fact that it doesn't like cold starting.

I have had the normal problems everyone seems to have untill you beef up eveything. Rear wheel bearings lasted 50mph, put loose bearings to replace bearing race, plug fouled at 75mph because the rich oil mix for break-in, intake and exhaust gaskets fell apart, front fender bracket broke, Tires blew and replaced with heavy duty Bell self healing. and evething vibrating loose. But if I keep the rpm down and run where the motor likes to run, I avoid most of the vibration problems. There is a learning curve with these bikes, but I am enjoying it more and more as I figure out the small bugs.
