Mitchelos Posted March 7, 2014 Posted March 7, 2014 Hi all i am new on this forum and new to motorbikes more or less. Last summer I got 4 motorbikes left to me by a friend who passed away. a 1972 Honda cb 125 twin, 1968 Parilla 125 sport, 1965 Beta camoscio Super Sport and a 1965 Bultaco TSS 125. I am looking for a shop manual for the honda am only able to find manuals for the single cb 125 and not the twin version. Or is it that it is not a cb 125 engine? Quote

fullscreenaging Posted March 7, 2014 Posted March 7, 2014 Welcome in. I've just done a quick Google and came across this. Don't know if it's for the twin though. Hope it's useful http://ebookily.org/pdf/honda-cb125-cb1 ... 69275.html Quote
Mitchelos Posted March 11, 2014 Author Posted March 11, 2014 Hi thnx for the search i had contact with the owner of the site that sells the manuals and this is for a single as far as he knows. And this is the problem I see everywhere that I am un able to find a twin version only thing I can think of is that it is not a 125 cc then but don't know how to figure out what engine it is then Quote
GazzyG Posted March 11, 2014 Posted March 11, 2014 http://m.ebay.com/itm/261420374422Can get the manual from eBay US. Quote
Mitchelos Posted March 12, 2014 Author Posted March 12, 2014 Deso thanks but still need to order then for 25 pounds orso and GazzyG the shipping one from eBay cost me over 45 dollars :S is there no online version?Here a picture of my honda. Only 1 fuel line was connected to tank and carb the other one only to carb and has an filter thingy and other side was not connected so took the tank of and on one side there is a fuel tap with open closed and reserve and the other side just bit of metal tube that is openly connected to the tank. I know the seat and tank are not original on this bike but will keep them on since I dont have anything else. Any advice on what to do with the unconnected fuel line to tank? Quote
Tango Posted March 12, 2014 Posted March 12, 2014 I'd think that the tube on one side would have a tube that runs across to the fuel tap on the other side....a kind of Balance pipe otherwise you'd have a large quantity of fuel on one side of the tank that would never get used...... Quote
Mitchelos Posted March 12, 2014 Author Posted March 12, 2014 Yeah but would expect 2 fuel taps then? and not one side a fuel tap and one side open I can be completely wrong since i have never been busy with bikes and had this and 3 others left to me. Quote

Mitchelos Posted March 12, 2014 Author Posted March 12, 2014 So how does this run exactly then this balance pipe? From there with the other to 1 then a tap and split again to both carbs? Quote
Tango Posted March 12, 2014 Posted March 12, 2014 So how does this run exactly then this balance pipe? From there with the other to 1 then a tap and split again to both carbs?I would guess that would be the case......with the one tap feeding both carbs. I seem to remember that the balance tube actually ran under the frame....so in order to remove the tank it had to be drained as the balance tube had to be disconnected to get the tank off..... Quote
Mitchelos Posted March 12, 2014 Author Posted March 12, 2014 Wont I get any problems then with enough fuel feeding the carbs? Sorry for asking these questions it is just that I am new to this and trying to get the hang of it all and want to be sure what i am (going) to do before messing it up Quote

Mitchelos Posted March 12, 2014 Author Posted March 12, 2014 true but will the carbs just "suck" more fuel out of the tank then or will i need bigger fuel line for the bit where it is joined from 2 to 1 and then split to 2 thinner ones? Quote
Mitchelos Posted March 14, 2014 Author Posted March 14, 2014 I deciphered my engine number any way to get more info through that somewhere?Engine Number is: CB125E 017627 Quote
