The best shops for P81 parts are A Main, Brooklyn, Mico, PRV Racing ((718) 938-8434) or direct through Motonica USA. More shops will be added to the list on the where to buy page later this week.

Play with the angle of the carb and position of the ball stud at the end of the carb. The linkage will go in between the bent part of the roll bar and the tank.

Are you looking for a clutch nut adjustment tool? If yes, I think the YBSLOW tool works fine.

By gaps, do you mean clutch settings? If yes, then start with enough shims between the inner bearing and threaded part of the crankshaft so that the bell spins freely without rubbing the shoe. Once that is set, set the end play/gap at about 0.4mm. Recheck after first couple of tanks.

I had my first test this past weekend with the P81. I tried different tire shores
with Garen's crystal park set up with very positive results. The car was so easy to drive . I did make some small changes that worked for me. My next test will be here in vegas this sunday. Thanks for coming out Garen.

Yes, it's a bit of a pain the first time, but not that difficult once you figure it out. You can loosen the spring by carefully bending it with pliers. For the nipples, I use a Hudy wrench (5.0mm?) and it gets them in with ease. Also be sure to apply some sealant to the nipples as a precaution.
Feel free to send me your tank and I'll put it together for you.

You will enjoy driving the P81. The track looks sweet.

I have a gearing question, i am using the stock gearing (p8.0r) with a tire diameter of 76/70. last race someone suggested using smaller tires during the qualifiers. i tried 63/67 and the car felt better to drive. But how small can you go on tires (guess this also depends on tire wear) and when do you have to change the gearing?

The smallest I have run is about 67/60. Too small and the chassis will bottom out and you will lose speed. I would not go any smaller than that.
There is a gearing/tire size chart on motonica.com for the P81, but you can use it for reference for the P8.0R 08.

checked the chart and took me a while to figure out how to read it, If i am correct then the speed using a 76mm rear tire with the 49 spur and 16t pinion would be 85, when i true or wear the rear tires to 73mm with the same spur and pinion the speed would be 81, so to get the same speed with the smaller tires i should use the 47t gear? Is this the correct way how the chart should be used?

Also the chart doesn't have any values for the 17/20t pinions, are those no longer used on the new car?
