#68 pilot

...despite the suggestion from Baja Designs to leave the stock pilot in my 650R after the power up kit, I put in a #68 pilot last night...and WOW...tons more bottom end (as if this bike needs any MORE low end), and lights off easier as well.

I hate to publicly disagree with such a good company (and no I'm not on their payroll) but I tried it anyway, and it really did help.

Did you get the 68s or the 68? Supposedly the 68s works better.

I didn't know there was a difference in any of the pilot jets??? What's the difference?

If so, please let me know that way I can get the 68s.

Thanks

I plan on putting in a 68 pilot jet too. My bike pops when I back off the gas. I put the needle kit in and did all the mods but not the pilot jet.

Here's a picture of the two side by side.

Thanks! I'll be pulling mine back out to see if it's an "S" or not.

does anybody have a part number by chance for the 68S?

Billy,

Please check this part number (68s pilot jet 99105-MBN-0680)against the 68 pilot jet part number that you already have.

Let me know if they are different.

This came from a search on a another site but I cannot confirm it on Service Honda as different from a 68 pilot.

I can provide a reliable source: Arrowhead Motorsports

I went to install the 68 pilot jet and I found the little plug on the intake manifold was missing. That is why I here poping when I back off the gas. I'm sucking in air. I know I put it on when I did the smog up grades. I might wait to see how it runs again before I change the pilot jet.

side by side, you will see that the "s" is shorter. I can't see why this would make any difference, it doesn't really stick out much past the body of the carb. It is highly unlikely that the size of the hole in the jet is different between "s" and "non-s"

I'm replacing the old "50s" with a "58" today, I'll let you guys know how it works.

That's all i'm changing this time. I hate to only make one change at a time because of what a pain it is to take the carb out, but yet if I change two or three things at once, I have no idea which change did what...

I don't recall one being any shorter than the other and certainly don't get that from looking at the picture in the link I posted earlier. The main hole through the jet should be the same between the 68 & 68s, but the emulsion holes between the two are definitely different sizes (68 = larger / 68s = smaller).

Does it help the snap off the bottom end? Sometimes I have hard time getting the front end up when I come to clearing an obstacle. I just did the standard uncork carb mod, main jet and needle. Guess mine still stock.

Using the right size pilot jet for your riding environment (altitude, temperature & humidity) that also best matches your bikes performance can make a huge difference in the bottom end performance. Now whether the 68s is right for your needs is something you'll have to try for yourself, but it only costs a couple dollars and it's easy enough to swap out (definitely worth trying!).

You can get the stock carb dialed in to where the off idle performance is fair with good bottom end performance just above idle, but you'll need a pumper carb to get the most from the off idle performance.
