Go-Tech Engines Thread
Ok guys, I'm planning some changes for 2011. One of the things I want to address is the lsn on the race engines. To my knowledge, we here in the US are the only ones that use the short/blunt lsn. 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.

The needle is a $5 part, i would think they could throw them in for nothing at whatever they cost to buy by the 1000. It probably ends up running about $1-2/needle by the time you buy that many.
occasionally would just die when i got to the 1st corner
is this after just refuelling ?
If so, run a longer pressure line than your fuel line.
+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.

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].
Just a tip - when fitting the new nitrile seals (particularly to the HSN) make sure you put a dab of lube or O Ring grease on them before installation.
With the newer GX double O Ring HSN's the upper (last O Ring to go in) can be very tight, and it is easy to damage or shred this O Ring trying to put it in dry.
