I took it out today for a 80 mile break in ride. The power is there but not like I was expecting...

I think I we install a larger jet and the larger nozzle that came with my Mikuni 42 when I bought it. I'll see what happens.

But I was expecting some reall noticable power, it's just not there! Or maybe it's because I'm being too careful. I don't know...just don't feel all warm and fuzzy...
Stock 88' is 3.750 across or 3 and 3/4 inches, big bore 95" is 3.875 across or 3 and 7/8 inches

Would you KNOW the compression you have in that build?

IF you are lower than 180-190- you don't have enough compression as that Makes POWER...

I would have used the domed pistons and had the Increase in Compression. Hind Sight IS 20/20

IF you have less compression now,,,,,Hard to get more without a piston change OR Milled down CC's in the heads.

Ask builder "IF" they used the .030 head gaskets? Just to see...

Stock cams or ??? in the bike.

Report back the ccc numbers if you would... Thanks and Sorry you didn't get the "Seat Of The Pants Build" you wanted.
