I got some cheap Alumiweld stuff at Harbor freight for cheap just to try it out. Well , I cleaned the peice that broke off to test it and used a wire brush to make it shine then porceeded to heat it with propane and I actually got a really good weld on the one peice that was broken. Then I clamped it on to a cleaned crankcase and tried but I could not get nothing to melt.Then I went and got some Mapp gas held it in certain spots for minutes and still couldnt get the stuff to melt. If I could just get the the case hot enough I could weld it and I bet the stuff would work , but I think the heat dissipates so quickly. It would also work better with the crankcase off , but if I am going to go through all that trouble I might as well send it off to Myspree.
Just messin around

I never thought of that

I stayed away from the center for the most part(I was welding with the bike upside down)
Just a question , Is it absolutely nessesary to have the muffler on the bike? I have the broken peice witht he pulse generator mounted on the muffler but if i were to relocate the pulse generator pickup and use no muffler , would that work? Just temporary?

you wont have hearing for long and you run the risk of smearing your piston

Ill just leave it be

I wish I could just install the muffler another way , mount it to another location. Any ideas on how and where? Will the muffler mount some where on the right side( i know it sounds stupid)
Any ideas? And Kenny , by smear the piston , what exactly do you mean?

Dude just do it the right way. Get yourself a steering wheel puller (I used a timing gear puller) to pull the flywheel off and to pull the right side of the case off. You won't even need to take the engine off the scooter.

If you find a right side case with a good bearing and seal you won't even need to replace them (I would though). Get yourself a new crankcase gasket, lube up the crank and case, tap the right side gently onto the crank until you can thread the bolts back into the left side and gradually pull them together. Done.

Is this a spree? Here ya go:

Would I need to mess with the piston ? You make it sound real easy. I can get a puller , and buy a new gasket.

I have heard on here and elsewhere that some of the years of Honda Spree motor parts will work on my 88 Elite.

If anyone knows, Which years and models?

Thanks for all the help guys!

you need to remove the jug and headbeause they help hold the case together

Would this be hard to do? I got pretty good mechanical skill , but never any thing with a motor like this. If everything looks good inside do I just replace the gasket?
Any info is very helpful thanks

BTW what is the jug?

Kenny_McCormic · Post by **Kenny_McCormic** » Sat Jul 07, 2007 5:09 pm

the jug is the big rusty finned metal thing that sits between the head and the case. removing it isnt hard after you remove all the shrouds and the muffler just take the 4 bolts next to the spark plug off and the head will pop off then the jug comes off.

I just recieved a puller but need to get the right sized bolts from the hardware store.
Since the crankcase is jacked anyway ,Do I still need to get a big puller to remove it? any tricks?

What spree model crankcases will fit my elite?
The one listed above on ebay?

Scooter Therapy has one , anywhere else I might look?
Thanks

I believe you are going to need 6mm bolts to pull the flywheel. Your head bolts may work with the puller, try them. Just make sure you don't thread the bolts too far into the flywheel or you may damage the alternator/cdi.

I had never done this before, but it is just a matter of doing it once to get the hang of it.

Re: Pulling flywheels
There are pullers designed specifically for the flywheel. Take a look at your flywheel, there is an internal thread just outside the nut in the center of the flywheel. The puller threads into that, then a screw tightens down to push the flywheel off the crank. It's a more robust puller anchor, because it threads into the flywheel hub.

The honda spree manual shows that style puller in the photo showing how to remove the flywheel.

My flywheel was really stuck (rust). I started with a puller and bolts like being talked about here, but when it didn't break loose easily, stopped and bought the correct puller. It was about $15.
