Main Jet 1983 gr650

[Scudder]

Anyone out there converted to pods? I'm wondering if someone can give me advice on where to start on main jets when using pods on my gr650 project. I know it's a hit and miss deal. I've switched to pods on other bike, but I'm wondering where to go from the 132.5 main jets that I found in the bike. I assuming 132.5 is stock. In the past I've started two sizes up and then started trying to adjust things from there. Is that in the ball park for a gr650. Unsure about the air induction system and how removign all that can effect the mains.

I would probably start with 140's if you are still using the stock exhaust.

Thanks. I have a straight pipe that is pinched to create some back pressure. Should I go a bit larger than 140's with this exhaust set-up?

With NO MUFFLERS, all bets are off!
Sell it to someone that is going to use mufflers.

It is not loud, like straight pipes, but does have a deeper tone, but not offensive. I have a cafe racer, that has the same muffler set-up and I run a stock air box. Crazy, but I pinch the exhaust tips down to make it sound good and create enough back pressure to make it run right. I guess I'll start with 140's and see what happens. If I can't figure it out, I'll return to stock.
