i did the scar mod and pair removal. I have no vacuum leaks and I followed all directions with adding three washers. I'm running a velocity stack and open exhaust.The plugs look perfect according to the picture chart. The more I turn the a/f screw out to richin it up, the worse it gets.It idles and starts perfect but as soon as you put a load on it the carb starts popping.I'm at the end of my rope.

Gottr' dun thanx.

Gottr' dun thanx.

Share with us! What was the problem?

 

[CUZMOTEEFOOSWA]

I doubled the foam filter and this added more restriction.The problem I have with this is that the plugs were always black like the carb was set too rich,but now it runs fine and the plugs look good.Retro Rich says if I'm runnung the true velocity stack, that I will need to put new jets in and maybe shim those.I will see when I put the new exhaust next week.

 

[Retro Rich]

Well, here's what I would do---if it runs good and the plugs indicate you're A/F is correct, keep an eye on your plugs. If the continue to look good over the next tankful or so and it's running the way you want it--I'd leave it alone. Any pics of your set-up? That would give me/us a better idea and ballpark estimate of what type of air your pulling. If it starts to indicate lean on your plug checks, then you'll want to look into moving up in jet size.

 

[CUZMOTEEFOOSWA]

I'll send some pics after I put the exhaust on.The problem is that my camera has such a high resolution that I can't shrink the photo far enough.If you want to host them I'll send them to you.I do have some in the 1300 gallery under MIKE'S BIKE.

 

[CUZMOTEEFOOSWA]

Actually, if you go to the 1300 gallery, it's the white C model.

V Stack

It's hard for me to see the bike running rich with a 195 and a V-Stack. What type of V-Stack are you running?? Any pics ?? Wow, I run a 203 with a standard Hyper no problem. Maybe we are looking at the wrong spot. :hmm2: :hmm2: GG

 

[Green Ghost]

I see It

Actually, if you go to the 1300 gallery, it's the white C model.

Well I see it. Good looking ride!! Are you sure the bike still has the stock 195 main in there? Spring Cut? Pilot Size? What kind of filter material are you putting over it? How do the plugs look after a 100 mi. ride?? Man I can't belive it would run at all sucking all that air with a 195. 55. GG

 

[Retro Rich]

Agreed GG; I looked at your pics Mike, with that set-up I think a stock 195 main would be rich, even shimmed. That V-stack will pull as much air, if not more, than most aftermarket airkits out there. What type of filter are you using on it? Even with a foam or oiled gauze element it wouldn't indicate to me that it would run rich from that little bit of air restriction (from the filter) with a stock main and pilot in there.

 

[CUZMOTEEFOOSWA]

Do you mean it should run lean with that much air?I'm using an oil foam from Thunder cycles.

 

[CUZMOTEEFOOSWA]

This is the exhaust that I am putting on this week.No baffles.Considering the stack and the open exhaust what should I start out with for jets?

 

[CUZMOTEEFOOSWA]

I have the hardest time postin a picture on this site!

 

[CUZMOTEEFOOSWA]

Here it is.

 

[Retro Rich]

Do you mean it should run lean with that much air?I'm using an oil foam from Thunder cycles.

Yes, sorry--typo error. That much air and a 195 stock main and stock pilot should be really lean IMHO. I don't see how it could run rich with that type of set-up; with those pipes you're putting on with no baffles, you will most likely be lean. My guess, you'll want to go with anywhere from a 200 Keihin up, probably a 205 or 210 is my guess since you probably have little to no restriction on intake or exhaust. I'd order all three mains, then start to experiment.

 

[CUZMOTEEFOOSWA]

Hey Rich, I can't find anyone who offers a larger main than 200.Any suggestions would be helpful.What is the model of carb we have?

 

[Lukester]

I had a simular problem on my 06 when i Put pipes and a jet kit in. tried riching the A/F but it also made it worse. Strang enough but when I leaned it out just a little more then when I made the first adjutment the proble was gone. no more poping and it runs better than ever.

 

[Retro Rich]

cuz,

You have a Keihin CV carb, you want a 393 series Main Jet. I'd call Factory Pro (go to factorypro.com website to get their number), you can buy individual main jets from them for like $3-4/each and shipping them is cheap since they have miniscule weight. Rage Performance was my other resource, but they had trouble getting a 200 for me and don't get anything bigger than that anyway.

 

[CUZMOTEEFOOSWA]

Thanks Rich,I ordered a 205 and 210 as per your advice,and I feel confident that this should cover it between shimming and a/f screw.Thats a heck of a deal for 7 bucks to my mail box.Let you know what happens.Next we will tackle the variable pitch turbo!!!!!
