This is my winter project. I started ripping it apart back in september so it doesn't look like this anymore. It in a million pieces but I wanted to post an official project on the forums. I want to thank everyone who has given me advice and help so far. Updates to come. The engine will be hopefully be completed in the next couple of weeks. Until then thanks everyone.

O yea. Picked this baby up for free,

you should have seen the smile on my face although it was not running.

as an update to my case issues, i ended up drilling straight through the bottom of the case and fitting a spacer and 10mm bolt to seal it. i think it should werk.

Those are called "knock pins" check out the CB750F manual and parts fiche for exactly where they go.

hey bwj, that looks the same as the breakdown i have, its just unclear to me which one the 4 set down in

kenneyginter · « **Reply #10 on:** January 14, 2011, 08:29:15 PM »

are there suppose to be 8 knock pins on the top of the cylinder?

brandEn · « **Reply #11 on:** January 14, 2011, 09:23:11 PM »

Yup 8 of them. 4 inbetween each pair of cylinders each pin gets a seal as well.

kenneyginter · « **Reply #12 on:** January 14, 2011, 09:28:40 PM »

I am reading the "F Supplement" for the Factory Service Manual right now. It specifically notes that the 77 only has 4 of these, not 8 like previously.

Here is a link, the F2 section starts on page 25 and mentions this on 30: http://data.sohc4.net/HSMCB750F.pdf

Another F rejoins the land of the living and nothing will get a project started like a free bike either! Good luck and look forward to seeing the results.

kenneyginter · « **Reply #18 on:** January 22, 2011, 08:34:22 PM »

hey guys. got to werk on the bike this weekend. which one of these goes on top of the piston? is it the bigger ring or the smaller one? i cant find it in any of the breakdowns. thanks

kenneyginter · « **Reply #20 on:** January 23, 2011, 07:31:54 PM »

kenneyginter · « **Reply #21 on:** January 24, 2011, 02:51:56 PM »

can anyone help me out with the order the piston rings go on?

MasterChief750 · « **Reply #22 on:** January 26, 2011, 05:53:49 AM »

i believe its the one on the right, ur not reusing the rings are you?

That should answer the ring question.
Dont forget to stagger them accordingly.

RpBet · « **Reply #24 on:** January 27, 2011, 10:22:15 AM »

Kenny, I am with Masterchief, spend the extra $ and get new rings. But first Hone the barrels. You can grab a honing tool for $20
