misfire

Recently rebuilt a 1980 CT125, had high rev misfire, ( similar to "4 stroking") appeared to be due to cam shaft journal wear "bouncing" the points so had bearings made and fitted, still had a misfire which stopped when the advancer was locked, Someone previously had welded the original advancer...

Riding home this afternoon and noticed my orange ignition light began to dimly glow. As I carried on, the light began to get brighter. She's been running rough for some time and the person who was supposed to look at her for me has let me down. Got a photoshoot with Adventure Bike Magazine in...

Anyone else have surging / misfiring issues with a cabr model xl1000v ? The bike surges and almost feels like misring around the 3000 rpm area. I have fitted new plugs , air filter and fuel pump and also balanced the carbs but the problem persists. Is this a mixture problem ? As it seems like a...

Just cannot find the source of the misfire on this bike so going with basics and process of elimination. Having the cdi, coils, leads and caps tested hopefully. Waiting for a friend to come back with contact details. Regarding the carbs. Any of you guys/gals able to point me to a company with a...

Got a problem with a sort of misfire / rough running engine at the moment. Its not run smooth since I bought her, with this problem but changed plugs recently and it seems to have made matters worse. I'm thinking perhaps its a lead or coil breaking down as when you give her a handful, the...

Hi Guys Had a misfire when warm on my 700, so a quick browse of the forum suggested new plug caps be required. So just changed - and while I was in there put new NGK Iridium plugs in too. Now this is my first time doing any maintenance on this bike, and noticed not one but both plus were...

I know this one has been done to death- but i have just finally got my bike up and running in Australia. It was totally ruined by the Indian shipping company. But know i have it on the road and am leaving Brisbane Friday, only problem is an awful misfire- it happens at low rpm, making it hard...

Took my bike out yesterday and did 100 miles no problem. Today, it managed to do 3 miles, about long enough to warm up then developed a serious misfire on one cylinder and refusing to rev over 4000 and intermittently not firing at all. Managed to limp it home but I'm baffled and just thought I'd...

I'm after some advice as a relative bike newbie. I've posted previously about a persistent misfire between 3-4000 RPM - the bike isn't at all happy riding at below 3000 (chugs along as if in too high a gear). I took the bike apart last night to check the condition of the spark plugs after...

Guys, I've just got an NTV650 - so lets just say it's a Transalp engine ! Only 8000 from new and less than 1000 miles in the last 10 years, quite a find.:D Bike starts & runs well, but starts misfiring when you get to 60 or 50 if going up a hill. It won't go any more than 60. I've cleaned...

Hi. On my way to work this morning my bike started to misfire, last fueling was about 350km ago so I was afraid it was empty. But after some misfiring and almost stop it running normal again, so I took the shortest road to a get some fuel. I filled 18,5 liter with fuel. My Haynes manual says...

Hi folks I've finally come to my wits' end with my '98 XR400. I bought it a few months ago all working just fine, and a weekl later bundled it into a van with my brother's KTM, off to Wales to do the Yamaha Off Road Experience. (We had an awesome day by the way, I can totally recommend it!)...

Chaps, I'm trying to sort out the fueling on my 1999 S reg XR400 RX. Since making some baffles to make it quieter it runs a bit rough. According to the manual, 1996 and 1997 bikes have Keihin PDK1A carbs. 1998 and newer have PDK1C. The number on mine reads PD, and then below that reads K1FAMI7...

Hi guys, I was in the Paddy Dakar recently and found that the bike (RD07a) was cutting out after taking a few moto-x type jumps. I'm suspecting it's a fuel thing as it would start again after a few seconds. I also lobbed it onto it's side once during which time it was running for a few...

ok so my africa twin has started misfiring and spluttering it has had all the basic service work done and checked, oil and filter, air filter, spark plugs, choke plungers it seems to be a intermiten fault and dosent always happen but some times below 3000 revs it splutters and coughs, but...

Hi Everyone, Just bought an XR400 "03" I'm new to this kind of bike so stick with me. On the way to work there seems as if the bike is either making a slight misfire noise (only slight on full excelleration) or I could describe it as a slight popping noise? It does not seem to effect the...

Hi all, after putting the new airbox rubber on the RD03 and making sure there were no air leaks i went out on it last weekend i noticed a small misfire once but thought nothing else of it........................ however i went out on it today and on 3/4 to full throttle it holds back and...

Hi, Fitted heated grips direct to battery last night on my TA 650 All looked ok until this morning. A bit of a misfire at start of journey, but after 20 miles it was firing about once every lamppost. Rev counter bouncing around all over and on zero a lot of the time. Obviously disconnected...
