[QUOTE="Holmil, post: 15994, member: 293"] I have a BT-H mag on my Rapide which is about 5 years old and has covered 6 or 7 thousand miles. Last night after about 10 miles I stopped for petrol after which the bike refused to start. On checking the plugs, which were new a month ago the spark seemed weak. The journey to the petrol station was ok, the bike started from cold second kick, the only sign of trouble ahead was a miss fire when pulling away from a roundabout a low revs. I suspected an ignition problem, and after an hour or so of letting things cool down the bike started again. I pulled out of the petrol station and headed for home. After two or three hundred yards the bike dropped on to one cylinder and then stopped about another hundred yards later. I had to be carted home in the back of a van. This morning I checked the timing which is exactly as it was set up. There is a spark but doesn't seem very strong. There is fuel getting to the cylinder but the engine will not fire. On the final ride of last year the bike refused to start when warm, but I was at a friends house and after cleaning plugs we got it going and it got me home. I've been out three times previous to last night's outing this year but none involved stopping. Has anyone experienced a similar problem with a BT-H or am I barking up the wrong tree? The bike is displaying the same characteristics as when the original Lucas mag was on its way out. Thanks Donald. [/QUOTE]
