A 46mm in that stock cylinder would heat over so fast it wouldnt be funny. The walls would be tooooo thin.

Re: NEW MEMBER, NEWBIE QUESTIONS
I thought the Taz 44mm BBKs were manufactured specifically for this purpose. Is this thread just saying that he gets brand new Honda cylinders and bores them to 44mm?

Re: NEW MEMBER, NEWBIE QUESTIONS
What do the 44 and 48mms up the cc's to? Also, I was wondering if these little engines respond to mild port work?

Inattentive in Geometry Class
Greetings:
I too paid little attention to Mr. Flaherty in geometry class. Too busy testing various smoke between periods. Stupid days of youth.
AN-ee-how, the Volume of a Cylinder. Pie Are Squared times Height.
You know the diameter is - let's use the 48 BBK - 48 mm. That means the Radius is 24mm. You want the result in ccs, so that's 2.4 cm radius.
2.4 x 2.4 equals 5.76. That's your r-squared.
I use pi = 3.1416. It's close enough.
5.76 times 3.1416 = 18.095616. Thet-thar's your area of the circle. Now you multiply by the height, which is the crankshaft stroke of 37.4mm, or 3.74 cm.
18.095616 x 3.74 = 67.67760384 cubic centimeters. Call it 68.
Now your turn using the 44mm bore kit. Practice makes perfect!
