What are you trying to do exactly?? I mean, sorry - I know what you're asking about, but I guess my question is "why"? What's going on with the intake valves that you're looking at The Foam?

Sorry Cindy! I didn't preface that with any info. No problems with my bike. Just wanted to know how it's done, simply.

I know our bikes are set on the lean side from the factory and carbon buildup is not usually an issue in the intake, head and valves. I've just seen threads about it especially on cages, jeeps, etc. Was just wondering how it's done on our bikes if anyone had done it.
I know on the 1500's, especially the FI's, it is recommended now and then when they get hard to start. Someone here asked me on another thread and I thought I'd post the question here.

You can remove an air filter an pour Seafoam in a squirt or spray bottle and inject into the surge tank.

A clean dish detergent bottle works just fine.

So you rev the bike, give it a spray, keep the revs up hit another squirt etc. right? Is the surge tank the same as airbox?

The air box connects to the surge tank on the VN750, most bikes just have an air box. The squirt bottle works best, keep the rpm's up using about a half a can. Then at idle squirt in Seafoam until engine dies, pour Seafoam in the fuel tank and let set for 15-20 minutes the start the engine. You can put Seafoam in the tank before you start the process.

I'm a little slow and need even more clarification. What I think I understand is: gradually add 1/2 a can of SeaFoam to the surge tank with the engine running at high revs, then let it idle and add more SeaFoam until it dies. Put the rest of the SeaFoam in the gas tank, wait 20 minutes and start the engine. Is this correct? I understand you could add the SeaFoam to the tank to begin with.

I'm keepin' all the left over parts. I'm gonna use 'em to build another bike!

How do you add seafoam directly to your intake?


A large hypodermic syringe.

You just "inject it" into the intake boot between the carb and the clynder. Then seal the hole with a tiny machine screw when your done.
