D.N.K Posted February 16, 2013 Report Posted February 16, 2013 I have bought a set of brand new keihin carbs. Me question is, is there a cross over tube on these carbs like stock? I see a pipe coming out of the carb on top of the intake and I wanted to know what this was. Also do i need to run tubes from all the pipes coming out of the carb? Thanks so much. Been going on this forum for a long time (3 years) and decided its time to join. Quote
vulvafan537240 Posted February 17, 2013 Report Posted February 17, 2013 No crossover tube on keihins since they both have chokes. The other fittings are for overflow tubes. Quote

Starwriter Posted February 17, 2013 Report Posted February 17, 2013 Are you talking about this brass tube? I think that's for an autolube pump line. If you have it and don't cap it, you'll have a severe air leak. Quote

Starwriter Posted February 17, 2013 Report Posted February 17, 2013 Auto parts stores have rubber "vacuum caps" in all sizes. Throw a small zip tie on it for extra insurance that it won't fall off. Quote

D.N.K Posted February 19, 2013 Author Report Posted February 19, 2013 What did you pay for them and were, I have been looking around for them Try ebay. Some sellers are cheaper than others and some offer throttle cables so shop around. Quote
jscharphorn Posted February 19, 2013 Report Posted February 19, 2013 I thought someone said you can get them for like $250, ebay is $350 Quote
vulvafan537240 Posted February 19, 2013 Report Posted February 19, 2013 Buy them used. I paid a little over 200 for my 35's. Quote
Starwriter Posted February 19, 2013 Report Posted February 19, 2013 Just beware of the knockoff Keihins. Some people have had problems with them. Some people say they work great. They do take a different main jet. The 1st clue of a knockoff is the steel splined looking idle speed screw like pictured here. The genuine Keihins have a black plastic speed screw. Of coarse it's always possible that someone could have changed that. Quote
jscharphorn Posted February 19, 2013 Report Posted February 19, 2013 Thats just Great, something else to have to watch out for. Quote
sheerider11 Posted February 19, 2013 Report Posted February 19, 2013 Holy shit. Those are really fake? Quote
D.N.K Posted February 19, 2013 Author Report Posted February 19, 2013 Thats just Great, something else to have to watch out for. Something that I got from a website are: -serial number is clear and stamped in proper -Plastic idle screw -Inside the float bowl there is a marking saying "pwk" -needles will have a code as following: Letter/number/letter -A star/"k" logo on the slide -A star/"K" logo on the main jet Quote
