that is going to be one sick setup when you get done with it.. one place you should check out if you want to get a big bore kit or motor mods done to your bike is Eric Gorr of forward motion.. he did my buddies bike and took his motor from being a big rust bucket when he bought the 500 to being the fastest thing ive ever ridden.. just a thought. :-P

The first bike I did was a 525 with an eric gorr jug. Umm... I wasnt really that impressed with his work. The cylinder had little pock marks & I paid for porting & he wouldnt touch it. When it came back it took a couple hours porting for me to call it useable. Slag around the rim of all the ports was bad, & the powervalve areas needed serious help. He did get it back quick though, & refunded the cost of the porting. This will eat it's lunch though.
I still cant figure how to get decent work done I pay in advance & try not to pressure but, crap work is just that. I'll have the bike I've been trying to get for the last 2 years soon though.

d**n.. sounds like you have have had a F****d up time with motors..when Gorr did my buddies it was clean and porting was done to make her scream.. i also had him do my top end and it was great.... but maybe you just know more about what its supposed to look like then me.. lol.. well if you find someone that does a quality job let me know.. thats one of the many things i wanna do to my 5hunny in the future... hope you get your bike to where you want it

You could go 91mm if you use the 88 or older cylinder, thats what I did. Haven't got the head right yet but when I get it I think it will be a pretty sweet combination
