Yamaha RD500LC
« on: February 08, 2018, 06:52:36 PM »
Hi all

I’m need of some help with the Rd500, it only runs on the bottom 2 cylinders, on the top it’s had new coil, ht leads, plugs and plug caps,
When I got it it was running on 3 cylinders, it now only runs on 2, I've emptied all 4 carb bowels to check if it had water in there. All had clean petrol pouring out. The air filter is new.

I’ve had the bike running and poured petrol into the top carbs and it still won’t run on the top cylinders.

So I’m at wits end with it, would anyone know a possible cause for this non runner on the top cylinders or know of anyone  that’s a dab hand with these V4 engines..........

Many thanks

Tony at AJ's in Hull knows the 500's inside out, certainly worth a call.   ;)      https://www.facebook.com/AjsVaopurClean/?hc_ref=ARR8LRsMvBribhx5XvKUZl-h4qHSqviTo8bLJN57G3S-HsKnV_Lax_vADdqPDMT23j8

Hi Dave

Spoke to Tony last week what a top bloke he was, drove half way down south to meet me to collect the bike on Saturday, just have to sit and wait for the phone call from him on the verdict on the problem of only running on the bottom two pots.

Soon as he lets me know. I will update on the problem.

Many thanks Dale
