1998 Magna Carb problems

[Billinva]

When I bought my 1997 Valkyrie Tourer three years ago, I decided to keep my 1998 Magna 750(27,000 miles). During the last three years, I have changed the gas on the Magna and run the motor several times,but have ridden it only once or twice(Insurance and tags removed). Yesterday, after a year of sitting,  I tried to get it running, but it would only idle on full choke with the front two cylinderds firing. There was no heat on the rear cylinder's pipes.

 What should I do next? Is there an easy fix or do I remove the carbs and clean the float chambers and jets?

              Thanks for any suggestions.

You missed the opportunity to drain the gas tank and carburetors and just let the bike set.

Now you have to get the crud out from within the carburetors and the gas tank which is causing the problem.

I suggest to use a gasoline additive in a heavy dose insuring the fuel mixture gets in the carburetors and letting it sit for a bit of time.

You should also ride the bike until you feel it is back to it's proper riding condition as it was prior to letting it sit for so long.

If you finally get it back running properly and intend to store it for an extended period, I strongly suggest to drain the gas tank and also all of the float bowls of the carburetors.

Good luck

Pull the carbs, remove the slow jets and throw in the garbage, remove the pilot screws and soak down the entire slow jet circuit with carb cleaner spray and let sit for just a bit. Blow through all the slow jet circuit orifices with compressed air (about 30psi is plenty) and then spray again with carb cleaner spray and let soak. Do this spray and blow and soak several times until the the spray comes out readily from the other orifices. Install new slow jets, check float levels, reinstall carbs and synch after starting bike. Should take care of your problem. One more thing, dump the gas if it's old (run in lawn mower) and put fresh in.

Thanks for the info. Today I removed the carbs on the Magna and checked the jets. The four slow jets and two of the main jets were completely plugged. After a year even with ethanol additives, the carbs were  really gunked up.

Next time, draining the float bowls should be the better way to go. I plan to try to keep the Valkyrie from getting in that condition.

That is how I came to be a Valkyrie owner.  Went to pick up my 2002 Magna from the dealer/service shop after they serviced the carbs [$$$].... traded it in for a 2000 Valkyrie that was on the showroom floor.
