Lack of power

[Lax]

Today I took my Deuce out for a drive and noticed it had about half the power it should. It started fine and idled fine but the best I could get was about 1,500-1,600 RPMs in 5th gear on flat land.

The fuel is old and I realized I have not changed the fuel filters in ages. The more I dove it it seemed to get a little better but no where near where it should. Any thoughts? I do think the turbo is working. It does not smoke any more then usual and when I shut down I can hear the turbo wind down too. Thanks for your thoughts

I would try new fuel and change all the fuel filters. Check the tank and filters to make sure you do not have anything growing in it.

And check the fuel tank for crud - you might want to flush it & the lines while your at it.

Great ideas. Can I get to the fuel tank filter through the sending unit in the tank and do you have any suggestions on what I can use to kill anything growing in there or the tank? Thanks.

How long has it sat?

I've noticed if I haven't taken mine out for a while, I havv to run it hard before she behaves like normal. Take her out and run her hard for an hour or more before you do anything. I have military nsn correct secondary filters with the correct gaskets if you decide to try changing filters, pm me.

Thanks for the tip. I'll take it out and flog it a little. Thank you.
