thanks  ill be sticking with the 103

Even staying with a 103"er, we've had carbed machines,(EFI will roll off more, as the ability to tune more) of this cubic inch, tuned at a outfit in PA, push off 119/119.

i ordered the cam conversion kit yesterday and my indy recommended the 55n andrews cam

i cant wait to start tearing into it

[MILLER82]

i havent ordered the head gaskets yet      should i order the cometic .030 or go with stock size since i will be milling the heads    my tech said he could just mill off based on wich one i get

wich one would be the best

Anyone answering this is just guessing until you fill in the blanks.

What pistons are you using?  Do you know the CC Value of the piston such as -1.5 cc or +7 cc ...   
How many CC's are the heads?
Are you at 0 deck height ?    If not, how far in the hole are the pistons?
Are you switching the pistons?
You need to know what compression the cam will handle.   
What compression do you want for the bike when your done?   

This all plays into the scenario.

The .030" head gasket is always a positive, as long as it is factored in to the compression equation, as the closer you can put the piston to the cylinder head during normal operating temps, without contact, the better you are able to control/eliminate detonation.

started the process last night i removed tank exhaust tb manifold rocker covers and arms. it wasnt too bad of job  the part that worries me is the cam chest   
i got the conversion kit from andrews with the 55n cam

i hope i can finish it!

With the correct tools....no problems

Just be careful of the o rings when reinstalling

i saw an oring on the back of the cam plate

now im finding out i dont have the cam bearing tool     does anyone have they would loan   i would pay a little bit to use it

If changing cams you'll need more than a bearing removal tool.  Separate tool for bearing installation.  Another to align the cams to press them in to came plate.  You're in need of several things actually.  Would loan you all mine but they're already on loan to someone else right now. 

Check out Heartland Products on Amazon.  Not sure they offer everything.  But what they do offer is usually quite a bit less expensive than the other sources.  Or, for very good tools from a place that will have everything, check out George's Garage.  You could call George, tell him the job you're doing, and he'll send the tools you need for the job.  Good guy, fair prices and very good tools.

I understand that it's a bit late in the task for this kind of homework.  Sounds like this is your next required step though.  George's is a good source.  Also, those connectors at the fuel injectors are sometimes a bit delicate.  The wires have been known to break where they make the turn down to the injector.  Rather than just twisting everything up there on top of the frame might be worthwhile to actually remove the TB and let the harness relax more.

got the bearings pulled on lunch with auto zone blind bearing puller

got the new ones installed

not sure about the press to press in new cams

[MILLER82]

so i got the motor all sealed back up and all i have left is to put manifold on and tb

my question is   the gut who done my heads is out for a week and he milled 60 off my heads     how will i know what the compression is? has any one milled 60 off these heads and have a figure?

[Twolanerider]

With the data known can't know with any accuracy.  Are pistons the same?  Any other work done in the head pockets?  Also, it's a little late in the process to only now be wondering about something as important as what the CR is going to be.  All the significant engine specs should be decided as targets before you start and the parts and build done accordingly. 

However....  You've got another issue to pay attention to.  Assuming you've changed to some higher lift cam.  You're now saying the heads have also been cut nearly a 1/16".  Hopefully you're not using a thinner gasket also.  Whatever you're using, however, you need to check very carefully for clearance.  It would suck to find out at first (attempted) start-up that a valve was now hitting a piston.

nothing was done in the pockets  i watched the head guy measure -lift of cam and the travel of valve/spring   

and he said there was still more room left

That "head guy" doing all the measurements with the parts in front of him should be your best source for a CR spec.  What's he say?

forgot to mention   pistons are the same    54n andrews cam  555 lift      238 duration
