TY250 Mono pistons
Posted: Thu Aug 17, 2017 11:20 am
Hi guys,
I haven't been on here for quite a long time so my query may have been addressed previously - sorry if so!
I have one of the original 1984 TY250 Monos - red frame/steel tank model (#53Y) which is currently getting a
tidy up so I can have a play again next season.
My question relates to the piston fitted to these bikes - I have been told by a UK supplier that the piston from
a Pinky will fit with no mods & will make a huge difference to the way the bike runs. (ports in rear of piston
are different apparently?)
Does anyone here have experience with doing this - I don't really want to buy a new piston assy to find that it
doesn't work & haven't got a Pinky piston I can look at to compare either.
I'm also tidying up the ports in the barrel as per Stan Stephens (UK tuner) in an effort to sort out the rattling &
clanging that these motors suffer from.
Thanks in advance for any info, Andy
