went out tonight on the bike got onto a nice strip of private road opened the bike up to 100+ mph rolled off the power and dropped it 2 coggs for a bendy bit rolled on the power and it just bogged it was revving to the red but just no power any ideas
Joking.
Its either fuel or spark. One of the carbs might of had something go amiss,and its running on one carb. Might explain lack of power, but no major or obvious problem _________________ Winning isn't everything, but loosing isn't anything
the funny thing was with it it has done it before and i just put it down to being in the wrong gear at the wrong time but took it out this morning down the m60 only doing 70ish and the some thing again. last night when i got back i went round it had a look at the plugs,choke,carbs,plug caps,ht leads,wiring loom,tank breather,fuel supply,cylinder compression and found that they were all ok ...................................
Dude,
Had a very similar problem with my MC11 on it's first ride out post-crash (the crash was near you neck of the woods, on the A640 at the back of Scammonden going towards Huddersfield).
It kept losing power after a good thrash. One cylinder was clearly dropping out as every now and again it would kick back in. Luckily this only started to happen within 1/2 mile of home.
Might be related, but then again might not as the MC11 and MC21 share nothing except the v-twin configuration and nikosil cylinder plating.
I think on mine it is most probably fuelling. I haven't stripped the airbox or carbs since it went down the road, so it could have either eaten the filter element or knocked some of the sediment out of the botton of the carb and blocked the jet. Alternatively, it could be the ATAC valve as it is the front pot that is cutting out.
Haven't had time to check it out yet, probably get round to it one night in the week or next weekend. I'll post what was wrong when I find out.
The choke was stuck open but the plug colour was good? _________________ MC21SP Plaything

Sorry dude I got a lift (from M62 J30!!) in today so I can't stop on my way home, shame really........
Still working on some contacts for a job for you if I can find them, I think it is the agencies that are taking on right now
Your "private road" wasn't the A62 to Marsden by any chance????? (Don't expect an answer to this one, "take the fifth!")
If it is be careful, as you approach Marsden there is a speed camera near the 30 limit sign, and the police sometimes speed trap before and after too. (But I'm guessing you know that already)
Used to live in Huddersfield, that's how I know the A62 and A640....... is the big "STOP" snow warning sign still at the bottom of the hill on the way out of Oldham on the A62 before you start the main climb?
