thanks, I have had two road stars and really enjoy the bike. Hopefully, someday I can get a nice paint job.
Thanks for all the good advice..

No you don't need to rejet. You may, but I doubt it, have to adjust your PMS. But ride it for a while and see how it runs.
Curious, Musky......My PO put the Longshots on my bike and I know he said that he had it rejetted (I believe he said the next larger size). Do you think his choice was 'overkill'? Again, I'm not much of a wrench turner and I haven't had the bike long.....but it does seem to 'struggle' to idle and runs with much more vibration thru the floorboards than I ever felt on my Warrior. I assume the filter is stock (the cover is), but I guess I should check that as well.
Thanks

Yup. The 1700's are plenty rich stock. It helps to lean them out just a tad putting on pipes. You for sure don't need to go bigger. What else did they change? Needle? Pilot? What are the settings if they did change more than the main?

Whilst looking over the vacuum pump/ carb stuff in the Technical section, I went to the Mikuni website and found a good amount of info. I recommend it, but print out a section of the carb (either from the tech section or Mikuni's PDFs) so you know what they are talking about and where it is located. All those cables, screws, floats, pilots and jets make for an interesting flight.

Question - If you have carbon build-up due to manifold leaks, lean or rich burning, how long does it take to clear the carbon deposits out using carb cleaner and spraying until stall, leave soak overnight, etc?? Or should that initial process clean out all deposits? Could it take two or more treatments??

Depends how thick it is.
I've found that if the buildup is not thick then a single ovenight treatment is sufficient to correct the problem.

I have very rarely seen a carb with significant carbon deposits Rayjay. The ones that did have some were running too lean and kind of 'cooked' their carbs.
If your not in that position, then you should be able to do fine periodically spraying cleaner directly into the throat, around all the pilot holes bottom below the butterfly valve, the front pilot air hole, and at the base of the needle where it slides into the needle jet.
If you cooked it, you might need to get it off the bike and disassemble it to do a satisfactory job.

Thanks guys.
I was referring to carbon build-up in the cylinder head areas. But you answered that one for me.
