Possible transmission problem

Postby Gnosistika » Sat May 21, 2016 6:31 am



Hi guys.

This is more of a question to confirm my suspicions.

Sometimes when I pull away from a stop too fast there is a terrible sound - a grinding sound or something that is flying around. This happens intermittently. Transmission?

This is the last ghost I have to lay to rest to get the old girl running smoothly. Am I right in my assumption?

Thank you in advance.

Could be the primary chain rattling due to the carbs needing synched......

Here's a test: when going up a hill, slow down, then shift into a gear that is too high for the speed you're going, so that you're lugging the engine. Open the throttle wide - does it make the same rattling noise? Then it's the primary chain. A carb sync will usually go a long way to helping if not fixing this problem.

It's amazing just how smooth these old machines can run when you've got everything spot-on. I see on your profile that you're also into BMWs...my last bike was a 74 R90/6. It took me 27 years to wear it out. I was hoping to keep it and restore it when I retired but couldn't make it happen so i sold it to a friend who will get it running someday.

@Overdog -
Sadly I have retired my BMW now. The cost of upkeep here has become too steep [only BMW sells parts for these bikes]. Her clutch failed and the cost to replace was $1200 four years ago, with our current exchange rate I am looking at almost double that. But as you rightly say, when these old machine are maintained they are things of beauty. I am hoping that I can keep the Goldwing running for a very long time, but SA's situation at present is only compounding the difficulties.
