Probably a little too lean on top. Long LSN settings - HSN .25 to .5 max in from flush. LSN 1 to 1.5 in from flush.
Read back on this thread a few pages about how the long LSN carb tunes. Basically set the HSN at .25 turns in and leave it alone. Do all your tuning with the LSN, maybe tweaking the HSN a screwdriver width as a last adjustment to get the last 15% of the rev range nice and crisp.
The 086 pipe suits the 5 Port better then the 053, but it will run fine with this pipe.

do you think its also good idea to shorten my long HSN on my 5 port or just leave it alone? what are the disadvantages/advantages upon doing so?
thank you
Don't mess with the HSN needle.
It is only the long 1.6" LSN needles that can throw people off when trying to tune the GO motors.
If you read the explanations and follow the instructions on the last few pages of this thread, your motor will run fine on the long needle. If you prefer a more traditional style of engine tuning (easier for most to get right I feel), then shorten the LSN down to 1.42" and away you go. With this needle fitted the GO motors will tune just like any other nitro motor.
