If you crank bearing are moving around in the cases you better get them sent for inserts that's bad.  They usually come out attached to the crank. 

Dezsled, ok, so I should also be looking into a new flywheel, is there a purpose to getting a lightened flywheel? or should I stick with stock. I do have a really good deal on machine work so it wouldnt be too bad to have any work done through him.

Iceracer, we were talking about you earlier on here. So Would I be better off getting inserts put into my cases or should I look for some replacement cases? not the cheapest route but its an option, I would like to keep it cheap since that cuts down on time that its in pieces, but still keeping it worthy of being rebuilt.

Or could it be that my bearings are just worn out because of the flywheel not being put on correctly?

I do love stories let hear about the 88 

So because I want this to be an all around bike I should probably stay away from that. Thanks for the education Motoman. Sorry about all the dumb questions, this is the first bike motor that I have ever tore down with the intent to rebuild it, so its a BIG learning curve for me.

So what would cause my bearings to be loose in my case? worn out bearings, or worn out cases?

Ok, So I should take my cases in and have them take a looka at doing inserts, I was looking at different cases on Ebay but, I think your right and they very well could be messed up too. Hopefully its only the 2 crank bearings that are bad. I would rather not pay for every bearing to need inserts.

How are they holding up thus far?

I havent had a problem out of it seen the inserts. I had Jerry Hall do the inserts at hpr. His number is in the service section at the bottom of forum board.

You've gotta cut out the down tub and fab an upside down Y into it for the pipe to go through. Only thing that I'm aware of that needs to be done.

now your talking DR, do the switch..

i think 2 down tubes would work, just take out the center one and put 2 new ones on each side,
and i think thats the only thing you need to do, then you wont have to take top end off to inspect reeds.

And I would have more performance, as well as more options for parts. Everything I read so far has said to cut out the lower part of the post, put complete motor in with exhaust, place pieces that are bent to form the upside down Y around exhaust and aline them so that you can weld bolt locations for the motor mounts. I would probably also weld the mount for the head just to do things right.

Looking at a good chunk of change for the rebuild on this motor, but I think I would save in the long run beacuse it doesent need as much machine work as my 86 motor does. What do you guys think?

Chuck, you should buy my 86 motor  after I get this done, just in case everything goes **** up.

Not to mention I would also need to get a different carb and CDI box, Right?

All of the CDI boxes on ebay show they work from 85-92 So I might be good on that part. arent stock carbs for the 90 34mm?

well figure to get what you want you gotta spend the cash, well oh well if I dont spend it then my wife will on things like clothes that arent stained with oil.

and it will probably be something that I can work on wait for funds, order parts, wait for parts, work on, then wait for funds again.

Ok Ill be buying the 90 motor tomorrow. Ill post up pics when I get her home.

I meant how much for the 86' you will be selling?....... LOL

The only reason I'm not going to do the same with my 86' is only because it was MY 1st quad. If it wasn't for that, I'd make the conversion myself. How much of a difference is there between the 1st generation and the other gen's in terms of HP & FTLB's?
