Ya hoping the same thing. If not then the pilot jets sell for like $20 for 4 on bikebandit: http://www.bikebandit.com/keihin-21-...lot-jet?m=2049. Pretty sure those are the ones.

I got this one: Motion Pro Syncpro Carburetor Tuner - Street Bike - Motorcycle Superstore

Was debating between that and this one though: Emgo Carburetor Synchronizer - Street Bike - Motorcycle Superstore


Both have good reviews and either one will work fine, but I just liked the liquid one better for some reason. It doesn't have numbers on it like the guage one, but I think I read in the instructions that the notches go in intervals of 5.

Thanks for the links stealthy, that liquid one looks nice! I thought it might have been the long screwdrivers you can get to reach and adjust the mixture will the bike still built.
I hooked up the gauge version to check mine before I stripped it but all was good, uploaded a quick video from my phone at the time...

Ya I was debating on that too, but I'm running out of money lol. Which is another reason why I'm waiting on buying new pilot jets. Need new tires more

My bike sat for a week before I got my jets and started working on it, but I tried starting it to do the same thing you did and it started once and had terrible throttle lag and I would have to open the throttle all the way to get it to go up in rpms. Once it got up though it ran perfect, but would die when I tried to let it idle again so I feel more confident it's my pilot jets.


Nice video too. Was it easy to set up the gauges?

The gauges couldn't be easier to setup, just pull the four pipes off the air box and connect to longer pipe going to gauges.

I did this again after cleaning my carbs a second time, also installed the Dynojet stage 1 jet kit with k&n filter.

Bike runs well but still hesitates below 3000rpm. I'm writing another post about a sub-air filter pipe I'm not sure is connected properly as I'm now clutching straws to the problem.

Get your pilot jets out for a clean it costs very little for some carb spray and a can of compressed air/foot pump.
