125cc 2 stoke victa

it was very old though, 35+ years
iwas told that ir would run at some 5500 rpm so i geared it low but it had no grunt

 

[my_mini_bike]

i got the throttle setup worked out yesterday and im now moving onto the brake cable, but i had a problem.. my cable was seized so i tried lubricating it... didnt work... infact just made things worse. just when i was about to buy a knew cable i had a great idea .. de-greaser!! works a treat, slides smoother than ever


seized cable..? hit it with some de-greaser

 

[2or3wheels]

Nice

 

[robin]

you shud lubricate any cable with light oil did you use grease ? if you did thats why it was sticking

Why not just buy a 3/4 sprocket instead of making a sleeve

Why not just buy a 3/4 sprocket instead of making a sleeve

i dont know the size of the chain/sprocket or how to work it out or where to get a new sprocket to be honest [without having to go overseas]. i had these two sprockets laying around so i figure just use them

 

[2or3wheels]

why not ship one, but i do like that your using what you have. where are you?

 

[my_mini_bike]

I surmised this when you said

125cc 2 stoke victa

it was very old though, 35+ years

I've been trying to get a 160cc Victa for a while now. Almost impossible to come by here in USA.

whats with the pipe?

 

[Russ2251]

Looks like attempt at 'Ram Air'? Might actually work with larger diameter pipe.

 

[2or3wheels]

might be. but think about this, your going forward and the motor intake is behind a motor which breaks the wind, so buy haveing it up front it may work even with just the same diameter tube. Just a thought.

 

[kibble]

I break the wind all the time, it doesn't stop me...

You're not playing with matches are you Mr. Kibble?
