430 topend rebuild

Hi guys,i need to freshen up the topend on my 83 wr430,going to 1st oversize(86.42mm) just hoping i could get some tips/sources on piston kit selection etc,i would like to stick with original mahle if i could but also wossner or wiseco,, also i have noticed woosner only list the 430 kit from 84-88 where as the 250 is listed 74-86 no 81/82/83 430 ? i keep hearing about piston seizure on this model, should i modify piston or is it more a fine jetting/tolerance/setup etc issue?any help or input would be greatly appreciated, cheers

I wouldn't know about the later questions in your post, as I'm new to Husky's, but I have seen sources for piston kits. Via a quick google search actually. Have seen the Wossner's, Wiseco's, and on occasion NOS Mahle's out there, in various overbore sizes.

Go to husqvarna-parts.com they have what you need.
