CHAIN SIZE+ FUEL LINES

[Rain Man]

I'm one of these misfortunates that dosen't have a bike shop around the corner. 2 questions: I have a Penton 125 six day and I believe it has a 428 chain, and the fuel lines are 6 mm.  I got a 57 toof sprocket in the back and my little book says 125 links.  Is this info correct ??  Thanks

Ray;
With the CMF frame it is safer to go with the 132 lengths and then fit the 428 chain.   It depends which size petcocks and carb fitting you have to determine fuel line size.   Make sure you put a good filter in the line also.   The 14 x 57 is good all around gearing for your 125 and your mountains.   Us flat landers and enduro riders use to use the 14 - 54 for more top speed to get back on schedule, or maybe some high speed horse play.

Thanks Doug, I think the fuel lines a 3/16,  and 428 chains should work. One more little order and it should be bringa bringa bring time.  The 4 wheelers are going buy the house now and the trails are still ice and water, won't be long
