cam degree questions

Im looking for some good numbers for a starting point with my cams. head is ported nicely sunk valve guides and all. 0.18 cometic gasket. stock head deck. stock pistons.08 race intake with stock 04 exhaust. I had a stock gasket on it with the cams pretty much @ stock timing and the bike ran great. Ive just put it back together with the cams the very same and the bike feels like it has no top end but has mid range and lots of bottom. any help would be great. The bike also had a very good tune on it before so I wouldn't think that would be it.

I had mine at 110/102 and it was too high in the rpm. My HP was still climbing big time at redline on dyno even though I have rev extended 500rpm. I am redoing them now along with some head work. putting the cams at 107/103 this time. Trust me 110/102 is too high.

Ok Well I finally put the cams back to a stock degree and timed correctly ( Very complicated with no markings on aftermarket adjustable gears.lol). I will take the bike down my street in the morning and If all is well after a couple short pulls, Il be off to the track to see what times it puts down with the new thin 0.18 gasket and some tuning. Best before was a 5.72 @124 with a 139 60ft. but had some traction issues at the big end( shock to stiff and tire pressure combination).

Well It did run ...OK, but Im thinking its a a/f issue along with cam degree combination . The bike is running very smooth with good low and mid range. Up top its giving up a little past about 9ish. I Know its not dangerously lean but it is a little lean. Im 185 lbs and will try to go with 109 /105 and get some dyno time. Btw Bike went 5.88 @120 with a 140 60ft best so its a little off considering with the added compression it should be in the high 5.60s at full potential if it was running 5.72s cnsistantly before. As Always Any EDUCATED thoughts or tips are greatly appreciated.
