Hope everyones enjoying a sunny bank holiday weekend 🍻 As the weathers good ive decided to give the bike a bit of a check over as ive done quite a bit of repair maintenance etc to keep her going well. One thing id like to check is valve clearances as i seem to get an exhaust effect from the air filter, mostly when the bikes cold? I will check timing and change fluids as well. Any advice, or opinions would be great as cant seem to find info on the 604 only suzi,s? Thank you |

If memory serves, I believe it's stupidly tight. 0.015" rings a bell... |

I drink too much, I swear too much, I ride too fast and I crash too often. It is a universal impossibility for me to leave my tools alone and my bikes standard. 'It must go faster!!' | |

Manual says 2 thou ( I recon thats too tight), So I set them up at 4 thou in, 6 thou ex, its worked for all my rotaxs with no tapping noises, also these settings are used by many other rotax owners. Edited by Monty, Apr 30 2016, 12:45 PM.

Would i potentially be along the right path? Miss fire type effect and almost stalling gone down to a 40 pilot from 50 on advice but problem seems to have got worse. Small amount of fuel in breather below float bowl? Problem has appeared since ive fitted a pumper carb. Poss too light slide spring? |

Why don't you give Gary a ring at Sportax as he is pioneering the pumper and should be able to give you some invaluable advice. |
