Gearbox broken - which replacement engine?

[keithcross]

Not to baffeling, different engines at different times.
I didnt think big end failure is normally associated with over reving, I thought the opposite was true. I am probablly wrong though. Maybe the whole problem was caused by oil pump failure, I really am not sure. One tuner I spoke to seemed to think the problem wasinitially caised by big end failure though (not sure of all of his details, but his first name is Steve and he resides in Suffolk I think).
Gearbox wear could be down to many things, I am not sure of the milage of the engie/gearbox unit and any problem may have been agrivated by clutchless gear changes
I am a little hard on engine on occasions though, had have the engine on my 1100 goldwing rebuilt by a specialist engine builder at 25,000 miles, then it failed again at 50,000 miles so I rebuilt it myself. Still going OK at 130,000 miles but it does use a little oil now

I suppose an idiot (not you) could lug the the big end to death....Did you buy it new or used ?
Clutchless gear changes are not bad in theory until they go horribly wrong...
Rebuilding an engine follows my personal maxim :
"Even on my worst day, I do better work than the specialist...."

Cheers..

I brought the bike brand new and used it for fun and commuting for 5 years. I am still unsure why the big end failed on the first engine. Maybe I did use the low down torque to much, I just love the sound of a big single at low revs, but on the second engine big end is fine and that was ridden in the same manner.
I suspect I was unlucky with the bearing that failed.
As for the specialist idea, I am actually a bit of a specialist, but on Honda Goldwings, being the technical editor for the Gold Wing Owners Club of Great Britain I don't however profess to being an expert on big singles.

I suspect the problem was not you....with those credentials.
MZ to Goldwing is a complete swing of the pendulum....
I don't have a clue as what I'm missing in a 6 cyl Goldwing,
all I know is if you have to get somewhere in traffic : take the MZ.
In my scheme : Motorcycles must be able to split traffic, be reliable and reasonably serviceable.

Had to reply to this one

The Goldwing is not that much wider than the my Baghira (maybe 3-4 inches or 100mm), the MZ is actually quite wide due to the type of handlebars fitted. I used to use my 1500 goldwing for commuting to Bushy (near Watford) from the Reading area, using the A312 through Hayes, to Harrow and then to Stanmore and Bushy. No problem with filtering, in fact it may even be easier on the wing as its much more visable and people tend to move out of its was
As for reliability, my 1500 now has 108000 miles on it and my old 1100 has 190000kms on it. While the 1100 has had some engine work done to it, the only time I have had to remove an engine case on the 1500 was to replace the clutch plates and spring at 105000 miles.
I enjoy riding all of my bikes, they all have their plus and minus points. The biggest minus with the Goldwing is cornering, the MZ and Aprilia are up to 50% quicker in some corners

Goldwings are legendary for long mileage...and complexity.
I suppose it's about a love of machinery. I've no experience riding something that heavy in traffic.
I ride the MZ Skorpion which is the Ginzu knife of traffic splitting....

[keithcross]

One of my friends in the Goldwing club reckons his Pan European will cut through traffic better than any other bike. He also reckons no normal road bike has ever overtaken him.. Mind you his Pan has 2 tone horns, blue flashing lights and is white with fluorescent yellow and orange stripes

well I spent good money and two days swapping the motor and a month later the b*****d thing has caught fire!!
Not enough to trigger an insurance claim which is tempting at this point in time, but just enough to totally f**k the wiring.
The loom under the rear of the tank is melted to a mess of plastic.

if anyone in the UK is looking for any Mastiff pasrts I'm now breaking the bike. See my post in the for sale area.

I had a spare engine I gave to a tunerbuilder to see what he could do with it-it had covere 78,000 miles (you read that right). Everything was withing tolerance, except for valve and clutch springs (all a bit tired). Don't know much about the history of the motor, but the builder didn't think it had been apart before, nor had it been lugged around at too low revs-no wear on 5th gear was evident (or something-i just heard him say the engine was perfect and everything else he said sounded like blah blah blah).

One tuner I spoke to seemed to think the problem wasinitially caised by big end failure though (not sure of all of his details, but his first name is Steve and he resides in Suffolk I think).

That would be Steve Ruth, lives in Acton neasr Long Melford. Ace supermono rider, and, like Slipstream, what he doesn't know about the 5 valve XTZ engine is probably not worth knowing. Nice bloke too.
