    What about one of these and some nitrous?

    Small Engine Turbo Charger - Small Turbo Kits | RHB31 VZ21 Turbo charger

    I bet you could gear the piss out of it, and get at least a couple of good passes that would be quite impressive.
    It ain't easy bein' fat and greasy.

    I will look at the link after I finish doing my bit for lung cancer..... sadly I think I already know that there are no available turbines to match a 125cc peak flow.....

    I do however know that small engines take well to sniffs of compressed gas.

    Gear it to do what you want and then rev it and slip it and rev it and rev it.

    Yorkshire Lavender...... It's quite a specific colour.......

    Had a chance to look at the specs of that turbine and sadly it's a no go for a 125. The manufacturer says it is nearly up to the spec of the RHF3 which doesn't start to boost until the engine is flowing 1.5 cubic metres of air, which on a 125cc running 100% pumping eficciency equates to 12000 rpm. I like the look of it for a 250 or a 400 but I reckon it's not gonna be of much use on a low revving 125 such as this. I will keep it in mind for when the CBR150 motor goes out to 197cc.

    Got a chance to strip it down and get it out of the way. Exhaust, forks, yokes, handlebars went straight in the bin as they were all junk. Before I got too far in I offered up the rear wheel and it will go on with no major dramas:

    Once I was down to a bare frame I whipped out the angle grinder and did the first wave of chopping:

    I hate angle grinders, especially those fitted with the wrong sized el cheapo disc and no guard.

    I've already spotted a couple of pit bike front ends that I fancy and I'm even tempted to go the extra few quid for adjustable front upside downeys. Some nice low rise bars will also be finding their way onto it.

    I'm also gonna get one of those fuel tanks from India, that a lot of people seem to be scared of, to see whether they are any good or not. If I stick to a budget of £500 I reckon I can build a nice machine for wifey to ride for a few months and then sell it for triple that to a hipster at the height of the season.

    Alright guys, im new to the scene but looking at getting a cg125, for anyone that has one built and running, if youse have got rid of the rear mud guard and air box, as most people seem todo if they've turned the standard cg in a cafe racer. How do you keep the shit off the roads going into the carb? Thanks in advance!

    Keep the standard airbox. One of it's primary functions is to stop shit getting in the carb.

    When are you looking to buy a CG and how much are you looking to spend Moody-98? I'm not too far from you so any help you need I'll be glad to assist.

    Main thing to do is not buy a pos and not turn what you buy into a pos.
