Re:Cobra Speedsters installation 5 Years, 5 Months ago  
So the consensus is that the TV protrudes more than the stock filter housing? I hope not. My leg rubs it too often for me. (6ft.) I thought I read somewhere that it didn't stick out as much as the stock box? Hmmm

Oh well, this far in dollar-wise, it's too late to stop now. Already bought the Twin. I looked at all of them and thought it was the best compliment to the bike's looks as it is now. The BAK almost had me sold until I read how the Twin Velocity is supposed to feed air more efficiently. I also saw a magazine write-up somewhere that said the Twin produced more power and flowed more air than the BAK. Hmmm Maybe I read it wrong. It's easy to get corn-fused these days.

Anyway, the Cobra pipes went on pretty smoothly. The loctite was tough on some, but nothing was over-tightened. A few too many pits and imperfections on the pipes for my taste, but the price was right. I paid and even $300 on Ebay including shipping. The sound is awesome! Probably louder than I wanted though. It's definately on it's way to becoming a hot rod and I love it.

My neighbor, who is the reason I bought a street bike after not having ridden for almost 20 years, is green with envy at this point. He bought a C50 Boulevard a couple of months ago and the sound of him pulling out every afternoon after work was jut too much for me. So I went looking and came home with this beautiful candy red Roadstar. His first words were "So you just had to buy something bigger, didn't you?" I told him I wasn't purposely trying to out-do him. I just fell in love with it when I saw it and knew it was right for me. His Suzuki is nice, but I'm glad I bought something big enough for my wife and I to cruise on. I would have been upgrading quickly if I had bought something smaller.

Next is the Twin Velocity and carb jetting. That should be interesting. I have an Innovate Motorsports analyzer I purchased for my drag car I plan on using to get the air/fuel right. It should make it easier. Haven't finished my drag car yet so I'm looking forward to using these new tools and my laptop to get the v-twin tuned up.

I did get a DynoJet kit for it and welcome any suggestions, tips and general flibber-flabber on the subject.

Happy Riding!

If you're 6ft you might try some floorboard extensions if you find out you're rubbing to much on your new air box. Might help.

Start a new post. It will be easier to keep track of your progress.

I'll be most interested to see what the analyzer says for the carb setup.

The feedback that I have received is that there's very little difference between the airboxes. Just go for whatever turns your crank.

Re:Cobra Speedsters installation 5 Years, 5 Months ago  
Well, once again I learned the hard way. Or should I say, the expensive way. If I had only waited one more day to buy a breather kit I would have read and learned from posts here that the Twin Velocity sticks out quite a bit further than the stock box and may cause problems for some riders. It's really in the way when I try to get on the rear brake in a hurry. I guess I'll get used to it.

I'm not really happy with the quality/fit/finish either. Specifically, one of the chromed tapered washers was not round and the elliptical shape caused the fastener head to fit so tightly that when turned it chipped most of the chrome off the washer! Add that to the fact that I had to go to 5 places to find the 12 point 1/4" socket needed to remove the cover screws during assembly and this just wasn't a smart purchase IMO.

I test drove it today and it definately adds power, but I'm just not happy with it sticking out so far and the fact that half the intake holes are covered by my pants leg.

I'm thinking maybe I can move it in by fabbing a new bracket with legs that stand-out less from the carb. Question is whether the rubber boot will be sustain its shape when compressed approx. 1" inward? Probably not.

My other option is to purchase forward controls for an additional 300 clams. Probably the only option that makes sense at this point.

Anyone want to buy a used (for one day) Twin Velocity breather? Price is right!
