Yamaha Skyliner won't rev but tick over ok - Yamaha Motorcycles

Since it's ticking along - no need for a spark test. This could be a few different things - if you've not cleaned the carburetor in awhile, you could have a clogged jet. It will idle fine all day long - if you try to get on the gas it spits and sputters. Not enough fuel, timing off, intermittent spark will throw out like symptoms. If you have a multi-meter I can find specs and walk you through making sure the spark is right from idle to throttle & check timing. - First, you would want to make sure that A. a steady supply of fuel is available from the tank - partially clogged filters and in-tank filters can make them starve for fuel, that your air filter is in good shape - and before you can go much further - if you haven't done it in awhile/the carb has to be cleaned and re-installed.

- Proper fuel supply is available
- Carb is cleaned/jets are clear
- ignition tests, timing
- I have to check the book - but that should definitely have a center-stand switch that stalls it out if lowered - but I have a Wolverine 350 Yamaha 1996 - and the parking brake initiates a safety mechanism - the bike will misfire if you go above a certain RPM with the parking brake on. If you can make sure your brakes are off just to rule that out as well - I'll keep an eye out for any messages -

All The Best, Justin M.
