Branden,
That Tarozzi  fork brace your fitting does that fit your  K lower legs OK ?  I was looking at their website ages ago and thought they only done  braces for F legs.  If they fit my K legs  I'll grab one , saves dikking around trying to machine it.
cheers Johno

They fit over the 77-78 K legs. I installed 78 forks just so I could install a fork brace. The 77-78 K fork lowers are a bit taller and don't use fork gaiters.

So this is my first attempt at timing a cam and I "think" I got it. If anyone can check my work I would appreciate it.


Mega Cycle 125-65


A duration at .040"


Lobe center 103.5 deg


intake open 25 BTC
intake close 52 ABC


Start at TDC






Measure until I have .040" of lift measured at the intake retainer





Verify I am at 25 deg BTDC





Find lobe center to be 103.5 deg




Am I doing this right?

Glad the MEGA wheel and tools worked out, thanks for the beers!  8) Looks like you did everything correctly and great picture documentation ad usual.  Hopefully some of the other engine gurus will chime in since I have only degreed twice.

Damn B, your frikkin nuts working in this heat, does S stand next to you with a spray bottle and mist you while you wrench???  :o

Wow that would be nice this time of year.
Up here the heat doesn't bother me as much as the humidity when it does get hot. I am originally from Northern California (Chico and Redding) and it gets above 100 F routinely during the summer but its not nearly as humid.

So after some reading up on the Web Camshaft site and a few helpful posts from this forum I got a better understanding of this whole cam degree task. I came home from work and double checked everything and measured total lift and crunched some numbers and calculated duration. I compared everything to the cam specs and it matched right up. Confident I got everything where it needs to be I applied some blue loctite to my cam sprocket bolts and snugged them up. Next I will adjust the valve lash and recheck everything. It feels good knowing how to do this! I have read that on the SOHC to adjust the intake and let the exhaust side fall where it does. I plan on doing this but I also plan on measuring the exhaust side just for the experience and to know whats going on with that side of the cam.

I'm curious about one thing. You are timing the intake side and letting fate rule the exhaust side. I think I read this somewhere too. But I think I also read to split the difference. Did you see that anywhere?

Yea actually I have read a few posts suggesting that. I went with a suggestion from Mike saying just go with lobe centerline, so that was what I focused on getting right. Hopefully I did it right!

If the cam is ground at all accurately it should line up pretty much exactly to the specs. There shouldn't be much "splitting the difference" involved. Not a bad idea to check though.

It looks like your degreeing process is OK. If your numbers lined up with your cam specs then that is good reassurance that you did it correctly.

Yes but you have to check the both sides.....the lobe seperation can be off a small amount which will effect the LC numbers....that's when you "split" the difference. Also...keep the indicator shaft parallel with the valve stem to avoid side deflection. ;) That retainer is plenty large enough... ;D

I am jealous that the 750 rockers are attached to the head and not the cover, so you can adjust them with the cover off instead of having to fit the damn feeler gauge in the little access port like I will have to do on my 550.
