Decided to turn my D&M Spike A/C to the forward position this afternoon from the vertical despite some saying it effected performance. It just looks so much better IMO. Anyway, I notice the fuel line is up against the frame in two spots, upon ispection both spots have nearly worn thru. Man, that could have been ugly had either one of those spots burst thru while riding. I have a steel braided hose that I will be installing. If your bike still has the stock rubber fuel line, do yourself a favor and inspect it.

My Ridgeback would lag at 65 mph when you hit the trottle with the spike facing forward. In a strong headwind it would almost die. With it turned upward I have no issues. I did see one bike with the spike set at 45 degrees off of vertical.

yeah thats what I hear, I wonder if a low pressure area is being created around that cone great enough to buck the air the carb is trying to pull in. In others words at a high enough speed, the air is just whizzing by around that cone shape robbing the carb of air. :loony:

well, nothing worked out to my liking. Spike turned forward created a surge and lag in throttle response at around 70 mph and I did'nt like the rubbing issue I can see with the braided line, plus the barbed fitting on the carb is to short to work with the hose end.
Went back with another stock 5/16 fuel line for now.

This reminds me of the time I sent my tank back to big dog on my 03 chopper. They bull shit emmissions pipe had come loose and they were fixing it. Long story short, I was about half way home when I noticed the tank was dripping oin the head and exhaust! When they welded the tank up, it sprung a leak in the lower bottom corner. I was so pissed that I coerced them into sending me a brand new tank to my front door, painted. :D

its a funny thing how you spot things when your not really looking for them. I'll do that from time to time.............just look the bike over for nothing in particular that is.

I use clear shrink tubing over my braided lines, I also color the braid with a good marker to match the paint before you add the shrink tube.

something like this in the 5/8 or 3/4 ( before shrinking )
my bikes fuel line length is just 21 inchs so maybe a local electrical shop that will sell it by the foot would be a better choice.
