Hi new to site, and it great ! My question is......
I have a 1985 honda spree that runs good, about 3400 miles, and still hits 3o mph with little problem. I bought it used so I have no idea what if any work has been done to motor. The problem I have is after the bike warms up I get a whislte\whine sound from the fan area. I tried to look in without removing the cover and it looks like the fan is not hitting anything.
has anyone heard of this ? and what could be wrong ? I am hoping it is not the crank bearings, but I am leaning that way. What do you think ?

Thanks in advance
Bill

well first, check your crank for play! that will tell you if its the bearings or not. just take off the pulley on the transmission side and grab the crank and see if you can freely at all move it up/down side to side. If you can move 1mm or more in any direction then its the bearings.

and if its running well those bearings may still last a while before finally giving out, as long as the case itself isnt leaking through them.

just things to check and think about.

yes do that first. with me it still ran good, i dont know how much longer it was going to last, but i didnt want to risk it considering bearings are cheap. but i didnt have play, i just had annoying noises.

Once the bearings are out you should be able to source them at any bearing shop.

Well I got the thing apart, and took the crank to a honda dealer to get them to pull the bearings off..... and the guy who works on bikes said all the bearings in the crank look great, no need to replace them unless I have $ to blow...... So I went home to inspect the spree better and found that the oil pump hold down bolt was loose, causing the gear to rub the case.... sound like this could be my problem ? anyone heard of this one ?
