So I have been out and about on the bike this week and am loving it.

Question though for all of us that have the fuel mod fitted...what position are you running in this cold weather?

Twin DNA filters, snorkel removed and twin race cans with baffles in and i have it set at 5 o'clock., nice, crisp throttle response.

Fitted one a couple of years (14k miles ago) and left it at 6pm. After removing the cylinder head at 30k I had quite a lot of carbon build up on the piston crown and valve seats. Two valves leaked in a bench-test.

At the same time as fitting the mod I fitted twin GPRs, DNA filter and open top, plus an O2 mod. Valve clearances had always been checked on schedule too.

I'm guessing the xs carbon was down to me and the 6pm setting as the ambient air temp is usually 20 plus here and I must have been running too rich for those two years. I set it at 6 because I , (confession), didn't want to burn a piston crown by being too lean. I should have trusted a 4 pm setting instead.

Interestingly I have an F1 daig tool and have only just found I can see the actual air temp and the 'adjusted' air temp as I dial in the mod.

There is a thread here somewhere about ambient temp / dial position.

Thanks for the replies..its the 'somewhere' that Im struggling with.I have looked .

Mine's been on 12 so I guess that's running lean. I got 12 from here...somewhere..

I think 12 o'clock is actually 'off' according to Kev's install sheet .... https://www.mediafire.com/folder/x1v...T660_Fuel_mods .. or

Thanks for the links..so when the dial is turned anticlockwise to its ultimate stop the units are turned off (position 12)..moving it clockwise to between 4 and 7 for Stages 1 and 2 DNA filters and race pipes is the given range..

It was set to 6...

I have now set it to 4 and will see how she now rides.

Still curious to see what setting others are using.. maybe we could get a list of People who have the mods done and what settings they are using for various temps and obviously what 'stage' the bikes are running..as a STICKIE or reference.
