Personally, I made the switch to the longer lsn and like the linear power curve. I also like the tuning characteristics of the longer lsn.

So... the 3 choices I have are:
Leave as-is and continue to offer the long lsn as an option.
Order all motors from here out with the long lsn and offer the short as an option.
Include both and slightly increase the dealer price and MAP of the motors and combos.

My JPX and RB engines have the short needle. Are you saying that they are special US models?

I persinally couldnt tune the long needle for crap. I can tune the short needle like no tomorrow. So i would like to see come with the shorts and have the longs as an option part. to keep the price of the motors down. Just my 2 cents

One thought, even though I'm not experienced with the long needle, if you made all future orders the long needle we would all tune by the same method worldwide.

Hi sorry to ask a simple question but what do you mean by flaming out on the track??? as mine just started doing that on sunday
The buggy would idle all day great and have plenty of decent low and high end power but occasionally would just die when i got to the 1st corner :weird:

Seriously- replace the seals in the carb. Up to gen 5.5 were reddish brown rubber seals. These degrade over time- even sitting on the shelf. The new black nitrile seals are a different world. You can validate this by taking out your lsn or hsn and looking at the seals. Shoot me an email at [email protected].

+1 It would certainly make explaining things on here a lot easier if everyone is reading from the same page.

Those who do struggle (which they shouldn't if they follow the recommendations properly), can still use the shorter needle to no ill effect.

Going on our experiance here, I would have the long needle fitted in the imported motors and offer the shorter needle as an after market option.
I think once customers use the long needle carb, they will be sold on it's smooth performance, and ease of tuning once they have the hang of it.
