07 800 Rev Performance Question

[sl*dhead6]

What can I do to "cleanup" the bottom end, it doesn't seem to spool the motor very rapidly. Meaning it seams a little sluggish from an idle. All stock expect for SLP can and regeared to 19/45. Thanks for any help.

Richen the main jets.

Mine does the same thing when it idles for awhile, feels like it loads up on the bottom but cleans up once I get it going. Apparently ^^ thats the fix?

How would increasing the main jets cleanout a bottom end thats sluggish?

Mine was doing the same thing I pulled my reeds and one of the corners was broke off. Put new reeds in and it is runnung perfect

DO NOT richen the mains. The mains will richen the entire carburation range to some degree. My recomendation, add compression. You could also try turning the fuel screw in a quarter turn at a time to see if it helps. If it does, drop one size on the pilot.

Much better approach to a lower rpm bog

That's what I was thinking also!

Thanks!

Bob, it should be just brutal off the bottom, even with all stock jetting. If anything they are a bit lean stock at out local altitude, especially down below 3,000ft.
The reed chip/crack is a possibility. How about correct spark plugs and gap? Belt deflection too loose?
Hopefully we get a chance to ride together before this year.

Plugs, Gap and Belt setup seem to be good. It has been this way since new. I was just wonder if there is a way to help it without porting and piping.
Thanks all.

WB, let me know next time you go out maybe we can get together.

mine was bogging, swapped out my belt and changed my plugs helped alot with the low end power., I also have some clutch update issues but that only shows on the top end under load
