Does anyone happen to have basically a revision list of the things done differently on the engines newer than 1984? I know the cases changed, but I don't think the cylinders or head did. I'm wondering if anything internal changed; gearbox, crank, chains, gears, etc...
Thanks in advance!
Your best bet is use a parts fich and compare part numbers through the three years.
One that shows the original part number and what replaced it.
Obviously some changes are done in sets, like the transmission gears and shift forks.
There are quite a few updates but it's hard to determine if the part number change was design physical or just change of supplier.
Mostly, the old will match with the new...but not
entirely.
