Title: Honda Barrel with KT stamped near exhaust port
Post by: suzuki27 on November 29, 2011, 06:46:23 pm

Anyone know what 2 stroke aircooled 70's Honda barrel had 'KT' stamped on the outside, in beneath the exhaust outlet? CR, MR , MT ??

Thanks for that Noel. I'm narrowing down the list  of what the mystery engine is in my "CR125". Pretty certain it's not a CR engine from 74-77! Thinking MR, maybe MT.

How many gears does it have,
MT MR only have 5 , CR has 6,
what sort or ignition CR CDI ,  MR MT points,
But all of those things are interchangeable as complete units,
MT  will also have provision for oil Pump in casing near counter shaft sproket
74 cases part number superceded  by 76 cases part number

If you have a 74 /75 barrel put that on and it will be OK pre 75.

Back in the day some people put a 175 cyl on the 125's to make them a 160cc :-X
