Bigger jets in stock Keihin carb?

I'm going to put in 58/165 jets in my 05 650L so it runs better with aftermarket exhaust, uncorking, etc. (Right now I have 55/158 and it leans out at 70-75 mph or so.) But I see Keihin jets that go WAY WAY bigger than that. Are any of you running bigger jets than 58/165? If so, what mods have you done?

I just put a dynojet kit on my 2006 XR650L I have a wileyco exhaust and K&N filter and have desnorkeled it. The improvement in trottle response and top end was outstanding! The kit cost $43.00 on ebay and it was well worth it! :thumbsup: It was a 165 main jet that I put on.http://photobucket.com/albums/e388/kelleyseiler/

A few questions for you... What's your top speed now? Stock gearing? Will it power wheelie in 2nd?

top speed is 85 to 90 but I really only got it there for a sec or two 2 fast for me on a dual sport. I run stock gearing as of now. And yes it wheelies too easy in 1st and super in 2nd

I was running a 58/160 keihin with a full com exaust and it ran fine. With the new mikuni it runs even better but it still wont power wheelie in second.

Ummmm it toped out at 85-90? thats horrible. She should do at least 105.
