Are you guys that are running 30mm carbs getting it into the stock boot from the airbox. It fits into the intake manifold fine. Also it has a 145 main in it now... would that be a decent starting point for my mods?
 
I put a blow dryer on it for a bit until it was soft and it went right on for me. I'm no tuning expert yet, but I think 145 would be a good starting point but does sound like a rich starting point. I have porting and stroker crank on mine gonna start with 150 and 42.5 pilot. And do some chops to see what's up.

Thanks a lot... thats what I figured I would try, well a heat gun. I thought it was good ball park but wanted someone to verify! Thanks
 
i used a heat gun on mine to stretch it. otherwise you can do a little cutting and stuff and use a short piece of pvc and a fernco coupler
