Title: Primary Chain?
Post by: hayabusa2785 on August 09, 2010, 11:48:51 AM
Hi everybody. I have a question, does GS500(2004) have primary chain. How the crankshaft transfer the power to clutch?

hayabusa2785,

I can't think of any motorcycle that transmits power from the engine to clutch by way of a chain.

The clutch basket sits on the end of the transmission input shaft. The basket and friction plates are driven off of the crankshaft, and the steel plates drive the transmission.

I can think of about a dozen that use a chain for primary drive  :thumb:.....all over 50 yrs old though  :D

I am sat down right now with this months copy of Classic Bike and it details the overhaul of the `Burman` type chain driven clutch found on the 1929 Ariel 557cc side-valve single.

Fair enough. A lot of Harlies are belt primary drive, now that I think about it... But again, that falls under 50 years old...

My Z750 has a primary chain, it's a '81 model.

The 1967 Cadillac Eldorado had a primary chain driving the gearbox, and front wheel drive.

But it wasn't a bike!

I know I'm not, I just paid $350 for a new primary chain to rebuild the bottom end.

Burning, quite a few bikes (and the Eldorado!) use a morse hy-vo chain for the primary drive, they are not a roller chain like the final drive, they have multiple link plates with internal 'teeth' and engage with a sprocket that looks more like a gear wheel.

Okay, cool. Disregard my overgeneralised statement.

The wierdest primary drive I ever rode was on a bike the kid next door made out of water pipe and steel angle, when I was at school. It originally had a two-stroke lawn mower engine and chain final drive. It was a bit slow, so he 'stretched' the frame and added a second motor, linked to the first by a V-belt. As you rode along, the slip in the belt meant that the relative timing of the two motors would gradually change, leading to weird cycles of vibration and a very strange exhaust note. :thumb:
