Carb differances o7 anthe new 08 on

Trying to find another carb to replace the o7 that I fumbled on to the cement and broke the low speed idle needle housing. Theres a lot of newer carbs available. Whats the difference or can one easily mod an o8 on?

I've had both in the garage at the same time but hadn't thought to try swapping. The only difference I've noticed is that the vacuum port to the fuel petcock has two outlets on the Gen2 to also provide vacuum to the air injection.

Has anyone started a list of differences between the bikes and posted?

Don't you mean Gen 2 having the split vacuum port?
I am new here and have looked around but not seen a thread on the Generation differences.

Yes, I meant Gen2 but if you go back and review my post you will see that's what I said. (Ignore the "edit" notation...that's not important)..

To the best of my knowledge, the only other difference in the carbs is that the '12 and up have the fuel inlet and the vent elbows permanently attached.

There are no other major differences that I am aware of that would prevent interchange.

Of course, the Gen 1 vs Gen 2 jetting is different but it's easy to swap the jet out, along with any other changes you may have made.

I see a body for sale and its a 2008 on Ebay for $48 delivered from sparkingdogg
Got the one I have patched up with couple layers of JB Weld and looks and runs good now but don't like the "I should have" feeling if I leave the county let alone if I haul it to Belize

Lucked out and a buddy tracked a 07 carb down that supposed to just need a cleaning and only $50 so that and a rebuild kit for $30 and hopefully will be back on the road without patches and have a fist of spare parts. Now to see about a newer battery.

I agree, especially when the guy who did the repair on the original carb probably won't honor the warranty. ;-)

Got the used carb apart after I got home yesterday and after some cooking and total stripping down and of course all needles and passages cleaned up the used carb fired up without any issues and only a tweak of the idle adjustment was needed. No rebuild kit and probably wont install one till something warrants it. Now the battery is the last major item on the list. Might get the bike on the road for around $100 this season. Picked up a pair of pelican style cases that now need mounts for $100.
