I'm looking into what it would cost for custom pistons to be built over here in Canada, once I get the price I'll compare it to Honda's stock piston and post that info. Considering the price that Honda wants for pistons and rings it may be one avenue for new pistons. The 1200 piston are approximately 75.5 mm or 2.97" in diameter. BTW, your most recent pics show up pretty good. Have you checked the cylinders for taper yet? Vic

haven't checked for taper, and may not. no news is good news. if I get too deep into this I will wind up spending more than I want. the trans parts I got off ebay look primo and now just waiting for the gasket set(also from ebay).

With the tops of the cylinders still having the cross hatch, I would bet there is no taper.

Gambler... you are right about the cost of rebuilding an engine.. However, there are a lot of factors to concider when overhauling... A recip aircraft engine is completely overhauled to bring it back to either "within tolerance" or "new" condition.. M/C eingines fall into the same catagory.. It all depends on how much you want to spend and what you're going to do with the finished product.. Rebuilding is certainly not cheap, BUT, you know what you've got. The engine can be brought back to the condition it was when it left the factory, retaining the original serial numbers, performance and longevity of service.. Used, or what we call LKQ (Like Kind & Quality) engines may be cheaper, BUT, what are you getting? Possibly an engine that's had the S__T beat out of it, not properly maintained with regular oil changes, improper maintenance and repairs etc. Also, you could install it in the bike and after starting it up, find it has a problem which requires it to be pulled again.. Warranties mean nothing if you have to do the job more than once. I know it takes a lot of work to overhaul one of these engines, but the built in quality of design is worth the price of the replacement parts..By the way, the ring price from the Bike Bandit is per cylinder.. I've bought many sets to know... The gasket sets range an average of $100 for each the upper and lower sets from a company in Italy... If you do the job correctly, it may be slightly higer than a used mill, but the results are well worth it.. Above all,,,, Have Fun!!!

The engine can be brought back to the condition it was when it left the factory, retaining the original serial numbers, performance and longevity of service.. all true, but this is a 200.00$ goldwing, and I could see spending 1500.00$ in parts or more to replace everything just for the engine. I've been thinking, hypothetically speaking, if you roll into your local honda dealer with say 30k miles on the clock and you have a trans gear problem. and it was still under extended warranty, would the factory authorise replacing all the rings and bearings and roller bearings? I don't think so, after all these engines were designed to go more than 100k mikes with the original parts. it's a gamble reusng so many old parts but I think it will be ok. if not, I still have other bikes to ride. and too, I would like to see if this is feasable, and if so maybe more 'wings will be put back into service for less than the cost of a new bike.

Replace gaskets and O rings. I thing other parts will be fine to reuse.

You're doing a great job, replace what must be replaced, reuse the rest of the parts. Keep up the good work and keep the pictures coming.

if anyone needs a specific shot of something, let me know. has anyone ever spun the alternator drive while it's out of the case, mine makes a clicking noise. it's not the bearing, it's coming from inside. it was not making noise when it was in the case and the bike was running so I think it is normal. maybe a one way clutch or gear reduction inside the unit. the bike was charging, so what about the stator? looks good as far as that goes but like anything electrical it could fail at any time. I found one on ebay for 155.00 new, and may order that soon. opinions?

I ordered a complete gasket set from ebay, 116.00 shipping included, hasn't arrived yet so no comment on the quality. supposed to come with all the o-rings also. where are you guys getting your water pumps from? mine has some play in the shaft so needs replaced.

I took this shot to show the differences between the 86 and the 87, the parts I needed were the shift drum and fith gear(which has the dogs which engage second gear)(thats the broken gear on top. these are the countershafts, looks like you can only use 5th gear(lucky me) Attachment: goldwing rebuild 091 (Small).jpg (Downloaded 434 times) Last edited on Sun Aug 21st, 2005 07:30 pm by Gambler ____________________ 87 GL1200 Interstate(reborn )

Gambler, have a look here for the water pump; http://www.powersportspro.com/ Click on the big fish to open the registration page, register, then once you're in your garage on the site, select 87 Gold Wing, then look under transmission cover in the pop up menu, item number 3, the water pump is $135. If you order in August they are offerenig a 15% discount. I've dealt with these folks in the past and found them to be reliable. I wonder if you could get a little clearer pic of the differences in the gears in that last shot? The lighting and the newspaper make it hard to distinguish the differences.

andrewns5, why don't you try checking for better pricing on those parts over the internet? On occasion I have found it cheaper to bring parts across the border myself (and pay the duty and shipping) than it would be for my local dealer to get the same parts. I think what happens in these cases is that the local dealer doesn't have the parts I need, so he would order from the internet himself and mark up the price of the parts by 25-35% after duty, exchange and shipping to sell my something I could have bought much cheaper if I did the ordering myself without the dealers help.

An old Cornbinder, if I remember right. A 1965 International Carryall we had at Kotzebue, AK blew the oil pan clear off due to gas collecting in the sump. Probably more from running too cold to get the gasoline evaporated out, but it was sure spectacular. Big bang, and a bunch of smoke. Watching the four guys bail out of it was comical too.
