I can not find anything on the net regarding camshaft for 1 piece heads. Does anyone know if they are different or all the same.

Does anyone know the dimensions of the xl185/xr200r bore. Might be a cheaper option to bolt one of these on, are they the same length as the sl125 bore? Will the crank and Conrod from the xl185/xr200r fit in the sl125. This is another option. Next will be the debate about horsepower vs torque.

After much searching and good luck I have found that people are building bucket racers out of xr200r engines. For bucket racing 160cc is max size. Unfortunately people do not elaborate on exactly what they do to down size the engine. Instead of building a hand grenade (maxing a sl125 engine)...

This is all great info. Will do search on gearbox ratios. Might have to transfer gearboxes or have a play with gear ratios between the two engines. Will not start spannering until I have a game plan. Good thing these engines are basic to work on. Will have to go old school and lube my gaskets...

Will bolt the k&n filter on. Just have to get the 26mm intake manifold adaptor. Can anyone tell me why the sl125 is knocked for its straight line speed.

Thanks for the info. Does anyone know why these bikes hate pod filters. Was going to bolt on my 26mm mikuni, but having second thoughts now. Will just stick with The 122cc with the xl125 head. Will give it a port (match the intakes and exhaust for better flow) and maybe see what lighter parts...

Bucket racers is a term used in OZ and NZ for old school low cc modified racing bikes. The comp is called super lites now but it is commonly called bucket racing. Been mini motard racing for years and want to step upto bucket racing. Mini motard racing is quite advanced with roller rocker heads...

Hi guys, just wanting to know a heap of information that is very hard to find. As the thread suggests I am wanting to make a bucket racer. Engine wise I have a cb100 and sl125 engine. I have read that the cb has more go than the sl. Is this correct and if so why. My thoughts are to fit an xl125...
