oem pistons with wiseco top rist pin bearings and clips ?

[dirtbike drew]

Hi. I just got some stock std bore cylinder and with oem std pistons. I was wanting to know if I can use wiseco top rist pin bearings. And the wiseco clips for the locking of the pin. ? And I want to know if I can reuse my base and head gaskets that only had 5 hours max of run time on them. There are not ripped or anything. I don't have to much cash at this time so if I won't hurt I want to know if it will be alright to reuse the gaskets. please let me know. Thanks for the help. Drew.

You might be able to reuse your gaskets if you use some type of spray sealer on them. I use copper seal spray on things like that as long as there's absolutely no tears of nicks in them. I don't know if I would chance it though either. Air leaks are bad. As far as your wrist pin question, I don't know. Love your signature. That's the only sticker I have on my shee.

I did use the copper gasket spray on them before and they came off with no tears in them. So I would use the gasket spray again. And I use the koltz benol that stuff smells good all the time. But thanks. Anyone else know about the wiseco bearings and clips. On the oem pistons. Thanks.

I woud think bearings would be same, e-mail or call wiseco to check. I would only use pin clips that are made for a particular piston,there again check with wiseco. Also , I NEVER re-use cir clips.

You need to use NEW Yamaha clips with the OEM pistons and NEW Wisco clips with Wiseco pistons. I would NOT reuse any base or head gasket- once it has been tightened down and ran through a heat cycle it will NOT conform to a new surface. If I was doing a repair ot in the boonies using the same parts then I would reuse them, but you are installing a different set of cylinders against your old cases and head. You really need to have new gaskets. The gaskets and wrist pin clips won't cost more than $60. You can use the Wisce wrist pin, it is the same size as the stocker.

Was out in garage and was looking thru an old Vitos catalog and they listed a 1mm and a 1.5mm clip , so you have to make sure you get correct size.

Ok thanks I took a wiseco circlip and put in my stock oem piston and it fit in there like it was made for it. In my denniskirk catalog for wiseco clips they 16mm clip and for the top end wiseco bearing is 16x21x23. But I don't know what size is for the oem. I had a local bike shop tell me I can use wiseco clip and top end bearings in the oem piston. I guess I will replace my top end gaskets. I still need to get a new crank. I just bought a set of 05 stock std cylinders and pistons and rings noport work with vary little time on the them for $245. Shipped. That was a score. Does anyone know what size oem clips and topend bearings are ? Thanks

You have the size of the OEM bearing listed in your post. The Wiseco bearing is the same as the OEM bearing.The bearing has to fit the rod and the wristpin which are both stock or stock sized.You can use the Wiseco pin in stock pistons because it is a 16mm diameter pin just like the Yamaha one. But, I was told the Wiseco pistons have a different size groove, requiring a different circlip. But, I could be wrong.
