Carb Identification

[Anonymous]

Thanks for the info Keith. A couple of questions. The manifold o rings?Are you talking about the rubber boots that go from the carb to the head? And the part # you gave for the Dynojet kit is that what I should use? I saw that they have a stage 3 kit for stock bikes with pipes but I didn't take note of the part #. Your bike is highly modified right?. I'll take a look through the carbs for condition of O rings. I have the carbs off now and the float bowls off and it is obvious that these carbs have been re built very recently. I know the timing is right I have checked and re checked it per the Dyna ignition instructions. I have checked the charging system and need a new regulator/ rectifier. I had planned on replacing the whole system with an Electrex system. It charges and runs okay but when you bypass the voltage regulator it still only puts out about 12v. Will it be neccessary to do that before doing all the jetting. Electrex kits are about $200 and the parts you listed are about $250 so it might be a couple of months before I can do all that. I'm willing to lay out the money if you say it can be done and done right. I'll check the valves although I've got a feeling they'll be okay, I have alot of receipts for maintanence on this bike. Looking forward to this project. Thanks.

The manifolds are between the carb and head. When you take them off you'll see the o-rings in a groove on the engine side of the manifold. Replace (unless you can't see any cracking) and apply some hi-temp' bearing grease to help them last. If you get new Allen bolts to replace those Phillips, torque to 6 ft/lb.
The stage 3 DJ jet kit for your bike is # 3304. It's designed for use with K&N pod filters and a quality pipe.
I bought the Electrex Reg/Rec, part # RR10. It was $110 4 years ago. Just be sure you've got good spark before jetting is what I'm saying. I listed all those things to check because that's how I do things. Not knowing the true condition of your engine I have to mention anything that can effect the re-jetting and make it more difficult. The costs can stack up, but you have to at least check all the things I mentioned and if you have to spend money, that's the price you pay for tuning the engine for more power.
The up side is the money/time spent on re-jetting will make the bike run well and not be too lean or too rich, which would cost you a lot more down the road. There are so many people out there that slap pods and a pipe on a bike, change just the mains 8O , and say "done".
