« on: January 28, 2012, 11:13:23 AM »
:-[G,day Guys,,,
I,ve asked these questions on a couple of other forums but havent got an answer from anywhere yet .
So what I would like to know is , can any of you guys tell me the compression for a 1970 T100C and same year TR6C, stock barrels and pistons, 9.0 to 1 from memory compression ratio, out of the box, meaning new specs.
And the other question is , some of you guys here know that I,ve got the above bikes amoungst others and that the T100C is a twin carb, and before everyone says Wrong, thats how it was ordered from the factory for the West Coast of the USA by Jo Mo.
What I,m trying to find out is the correct main jet size for the twin carbs, I,ve looked online and in two different workshop manuals that I have and have found 4 different sizes.
I just looked up under daytona but found such a big variation
Now I could buy 20 or so jets and start testing but I would have thought there would be a spec somewhere, or at least two places that said the same size so I could use as a starting point,,cheers and thanks in advance,,,
