First off. find out what parts are available. All lower gaskets and head cover gasket, exhaust gaskets. Cam chain and tensioner assy plus guide. You need to remove the motor and have a huge place for all the parts to lay out in order. Very slow and careful will do this job. Take notes of EVERYTHING and where it goes. With the motor out, I'll take you step by step. The secret is in being orderly. Measure each bolt and note where it came from. Becuse of the time this will take to do not assume you will remember details. Put the motor mount hardware back into the frame where it came from while the rest of the job is in progress. Enough for now. Do not start this job unless you have parts. The real Honda shop manual should be at hand. There are links to sites with them for free. For top-end work, any manual for a like model will do. 550sc,650sc,700/750sc, late model 750. As you progress, you can even degree the cams and make it really worthwhile. Many resto jobs I have done have come to naught because of parts availablity. That's why I insist on have parts first. Go slow, do it right.

There was an improved cam chain tensioner for those (now only part available if at all) I would replace the cam chain and tensioner at that mileage. Now the trick is to do it without disturbing anything. As long as it doesn't smoke and runs well, I would avoid messing with a good thing. What am I talking about ? The manual says to remove the upper end and a ton of stuff to do this. There is a better way. I can walk you through the process. BUT, you have to accept that this requires you to remove the engine. If you're up for it. my method will leave the head and cylinder block in place with the pistons still in place. For a skilled tech this would take about eight hours. For a novice, expect it to take up a lot of room for and time. Good winter project. --- On Fri, 2/13/09, Dominick <[email protected]> wrote: From: Dominick <[email protected]> Subject: [Nighthawk Lovers] 84 650 Cam Chain Adjuster, SS Valves or Chain? To: "Nighthawk Motorcycle Lovers!" <[email protected]> Date: Friday, February 13, 2009, 5:20 PM 54K miles on bike does not smoke, runs like a bear but noticable rattle at lower rpms & idle. The bike seams to be bullet proof. Searching NML history I've read about CC Adjuster, Chain or Stainless Steel valve guides. We just ordered a Clymers not received yet. Would it smoke if the valve guides were bad & has anyone heard of a chain breaking or jumping? Is there a breif description or online illustration to verify the tensioner first - I'm goin in.... --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Nighthawk Motorcycle Lovers!" group.
