In my GX-7R (bought in China), I'm running at idle gap 0.7mm, 0.5 turns HSN, LSN 2 turns, 7mm restrictor, 100 degrees(C) and go2072 pipe. I can not more than 8.5 minutes of the tank.

Fuel Byron 25% - 4 shimm - OD97T
XRay 808, 17T clutch bell

Sorry my bad English!

Hi Alex, the run time thing has a lot of variables. Track surface (amount of dust and wheelspin), fuel type, ambient conditions, tuning, and a quite throttle finger are the main culprits

If your on a dusty track with a 7mm restrictor your times are probably not too far off. Your needle settings sound about right for the long needle carb (which you will have seeing the motor was purchased in China)
In the summertime when our track is pretty dusty and slippery anything over 9 mins with the 2072 pipe and 7mm restrictor is pretty good for me (I don't run my motors on the limit as a rule, so I am probably a little down on some others run times).
The only way I get 10 min on our local tracks with normal ambient conditions is with a 6.5 restrictor and 086 pipe. The bottom end punch is a little less than the 2072, but run time is much improved.
I have tried the 086 on the 3R, 5R and MG66, but not on the 7 Port. With the top end on the 7 Port and the high end 086 pipe it might be a sweet combo.

With the 2072 pipe, try running the 6.5 restrictor and going down to .4mm of head shims (remove 1 x thin copper .1mm shim - leaving 1 x .3mm alloy and 1 x thin .1mm copper). This should give you a little extra run time.

I know some guys are getting over 10 min in buggy and around 12 - 13 min in truggy, so hopefully they will pop up on here and reveal their secrets

HE IS A VERY BUSY GUY!...AND GO ENGINES ARE GETTING BIGGER SO HE HAS ALOT OF PEOPLE TO TAKE CARE OF BIENG ONLY 1 GUY....HE WILL TAKE CARE OF YOU FOR SURE!

hey... as I stated in the email, I entered your zip code wrong and UPS neglected to notify me they couldnt deliver. I did send you another setup w/ the long LSN as requested.

For any of you guys in the states that are interested.
