Hi Billy,

I have finally gotten my hands on a 1983 V65 Magna Project bike. Inevitably, I will need to tear the carbs down to do the cleaning and rebuild. Would you be able to recommend the jetting setup and a kit that I would source from you once I get to this point.
Many thoughts for your expertise in advance.

40 slows, 142, maybe 145 mains. It is hard to dial it in perfect without a dyno/O2 wand up the pipe.
You want the mega or mega + kit. On the website or Billys Place here at the bottom pf the page.

With a stock filter I'd probably stay with the 140, if you're going to put a K&N filter in it then consider upping to 142.

I'm running stock air filter, 70A carbs, laser headers and Mac mufflers. 142 mains and 40 slows, 1HE needles, 6mm float height. At sea level, she ran over 100rwhp with an A/F ratio just at or above 13.0:1. 145s would be fat, especially at altitude and/or on a warmer day. Would the K&N justify 145s with your exhaust? Maaaaybe. With stock exhaust? No way, Jose.

I'd start with 142s.

Many thanks to all for your comments. I removed the carburetors late last night and noted 155 mains and 38 Pilots in all carbs?? Billy I would like to order your super + carb kit. Would it be more beneficial for me to go direct through you on the forum or through ebay. My PAYPAL is djohns4@bellsouth.net. Jetting sounds a bit crazy for a single exhaust kerker pipe...but I need to get this bike up and running before I start changing things? Billy I'll call you to discuss. Contact number please. I welcome any comments from the group. All the best Dave

Sounds like someone didn't know how to jet---that's an unbelievable mismatch.

  On the plus side, if you are having a cookout/outdoor party you can ride your bike around your block a few times and kill off all the skeeters.
