Haha. That's a nice problem to have. Great collection. That green Yamaha looks like my very fist bike, a 1972 DT250. Same color too.

Thanks.

Green bike is 1973 model DT3 - 250cc and the frame dated stamped as manufactured in 1972. The silver bike next to it is a 1972 model RT2 (360cc). My 1974 DT360A is currently in the greenhouse!

Good morning and Happy New Year everyone!

I've finally got around to reorganising the garage and the GS550 is now in the "working" area!

I still can't find any sign of the igniter box.

Photo of under the right side engine/crank case attached - should I be able to move one side of what that spring is attached to?

Anyway, a different approach might be for me to list my issues and then maybe someone can point me in the right direction.

1) Bike starts readily enough. I started it this morning using a remote tank - petrol tank removed and therefore (vacuum?) hole on the top of the carbs open.

2) It won't rev above about 3k.

3) To my mind, it is running hot - at least it appears hotter than other bikes I've owned.

4) Brand new Delkevic exhaust system fitted. In "road" standard, so baffle in place.

5) I would say that the bike ran hot and didn't really rev out before I swapped the original exhaust for the Delkevic. By the way, if your wondering why I changed it, the original left side disintegrated when I removed it to get to the rear wheel axle!

6) New air filter fitted, but issue remains whether or not the filter is present.

Any pointers would be much appreciated and apologies for taking so long to pick up the thread.

Thanks.

When using the aux fuel tank you need to plug that vacuum port on the front of carb# 2, or plug the hose coming from it might be easier.

The ignitor is somewhere around the airbox. You might want to remove both side covers and the chain guard, that should provide enough vewing room to find it.

Also, put a fan in front of the engine. Never run an air cooled motorcycle more than a few minutes without air flow.

Huzzah, found it!

Steering me to look past the chain guard is wot dun it. It is attached to the underside of the air filter housing - sincere apologies if someone had suggested this to me previously, but I was too daft to understand.

Next question, would a dodgy igniter box cause my symptoms?

Thanks again.

Can't say what's wrong. What I can say is that you may want to read through the Newbie Mistakes thread linked in my signature. It's likely to help you...

???

Am I missing something?

Thanks to all for your replies.

Looks like my non revving above 3k issue was down to a stiff advance/retard mechanism - ie it wasn't working as it should.
