2006 Vk trouble starting

[Harvey Lunnen]

Replaced spark plugs and battery started perfect. Left outside for a week cranks over fine won't start.
Any suggestions?

Spray the carbs with a silicone spray. What I do after mine has set for a while. Better than starting fluid.

Was your machine stored properly over the summer ie: fuel stabilizer or carbs drained, If not you are probably going to need your carbs removed and cleaned then synchronized! This is a must for carbed 2 or 4 stroke engines, more so for 4 strokes do to the machine can run very rich to a point where it will fill the base with fuel resulting in engine damage!

Sometimes it can loose its prime when sitting for a while, try taking the air filter off so you expose the crab intakes and put a drop of fuel down each cylinder then try and start. Good luck

throw a boost pack on it and try a full synthetic oil change. helps it crank faster. might have to pressureise the vent line on the fuel tank to get it to prime again as that motor like to bleed back when not run enough.
