Ok.. time for some brain picking.. Does anyone know which (if any) Wiseco piston will fit an 87 Tecate 4 72mm big bore? Part #439M07200 is supposedly for 85-87 Tecate 3- Wanted to know if anyone has a clue about "interchangability" because I surely don't.. also- what "mods" need to be done to PV's and head? Scored a sleeved 72mm jug and really want to use it! Please and a big THANK YOU!!

I would call Great at Off-Road Innovations. A few weeks ago I was looking for a 74mm piston and he had 72 and 73mm in stock for the big bore. He also has a large selection of the old Wiseco pistons that are lighter weight than the new ones. Give him a shot first, then reach out to Dave at ILR Second. http://www.off-roadinnovation. com/
Thanks Joel.. Greg @ Offroad Innovation is a good dude with those hard to find parts- for SURE! That's most likely where I'll buy from. Just looking for a little insight into the "interchangability".. what has to be done to my PV'S & head? (Sounds like you may know)
If you are running that stroker set up I would run a Sprock head and just make sure your power valves are times correctly. I have a 300 T4 that has the billet power valves ported and I can't tell a difference. That's my .02.
The piston in a 1987-1989 KX250 is the same one as well , if it helps to cross reference
