Well,I finally got to dyno my bike.Not real good or real bad.Time to redo my worn heads.The valve springs are too weak to set the valves properly.

Are you internally stock? Sounds like 120 plus ain't too bad for internally stock....

I bored it out 2 winters ago and went with 87 mm yamaha pistons.Stage 7 and HMF exhaust.
I have it at Rods shop right now.We are doing a compression check and leak down test tonight before tearing the heads off.These are my stock heads,41k on them.I did the bores at 36k.There's more horse power to be had in there.

Sean was right ,I meant 77mm not 87mm bores.

Roughly, what should these bikes be putting down? Say for a stock 97'.

From what I understand they can be anywhere from 100 -130hp depending on the bike and state of tune.

So, Shawn, what are you having done? Are you getting into the bottom of the engine, or just head/valve work?

We tested my compression last night and it was 155lb.,so the bottom end is still in pretty good shape.I only have about 6k on the bottom end since rebuilding it.
I am not toally sure what all we are going to do yet.Porting and cam sprocket slotting for sure.I am letting Rod decide ,He is the motor horsepower master.
I took the heads off last night after that.The bores still look really good.

Are you sure you didn't bore it to 78mm?????

Still looked about right on numbers from what I could tell on your sheet.
