    Try putting 2stroke power valves in a 4 stroke engine they work twice as good.

    Add the power band, that will really make it take off.

    ...and the tighter you wind the band the better it will take off. Flies farther too.

    I always like a good turbo boost.

    The most common (and logical) performance boost for the TW comprises of two stages …..

    First up, (and with a change of sprocket sizes), is the Nitrous kit - Yamaha TW 125 TW 200 E R S Trailway NOS Nitrous Oxide Kit & Boost Bottle | eBay


    6252938.jpg


    This works best on Californian models, where the additional canister carb connection can easily be re-routed. If you’re fortunate enough to have a carb with that “little red button”, then this port can also be utilised. Please ensure the clutch is fully engaged during use, and that a suitable gear is selected. 70mph in 5th is advisable (on a 42 tooth rear sprocket)

    Once speeds of over 80mph are reached, then activate the next stage – the 8AS-200 JATO unit has been superseded by the 12NS-350 JATO, which may be more widely available, and has increased thrust. Both JATO units can be mounted in the usual “tool tubes”, and affixed to the rear rack (recommended)


    200.jpg.. – ..350.jpg


    The 200 motor is on the left – the 350 motor on the right

    If using the JATO motors/s approaching a hill, the firing solution should be obvious – on the flat, we recommend the “bunny hop” manoeuvre for improved trajectory

    Don’t forget – stay safe out there – and above all, have fun …….

    I put that nitrous on the BW200 for a few runs... doesn't last long but it was fun while it lasted.
