If the TPS tests ok then unfortunately the next item is the ICM

No, the official workshop manual which you can download (the links are here somewhere!) but the haynes one may do.

Ahhhh my bike was called Holly - dunno if pikeman will rename her now.

Them there aint carbs, they be throttle bodies and no, i will not make you a ECU !!

Ohhh i see my name mentioned..... :) The symptoms that you have described IMHO only point to 1 thing and that is the ignition advance, the 3500-4000 rpm you mentioned is the point where the engine will start to splutter if the ignition timing is static. Carry out the tests in section 17 of the works...

My pleasure Matt, anymore questions you know where i am

Just thinking out loud here.....

Your problem of "mis-firing" was first at 5000 rpm, you cleaned the carbs and it moved to 7500 rpm, now that seems to indicate to me it is not an ignition fault and the problem is still with the carbs.

Tony, my ex said to get them both but she had £ signs in her eyes :roll: Next time i see him, i'll ask the price for both. Parts are cheaper then Honda and some of the common problem areas, valves and final drive gears were re-done in the last few years :) Now i just have to raise some money :(

Theoretical speed of 149 mph

On my way to the local shops i got chatting with a guy who has 4 Guzzi's in his garage, he mentioned last year that he wants to get rid of the 2 oldest ones, an 82 V50 Mk3 and a Spada. It hasn't run for a couple of years and needs some work doing to it but overall it looks a sound bike, he wants £3...

It seems like Igor has almost cracked it

Next step, get them carbs balanced before trying anything else

errrr thats not right, the butterfly governs the air flow, which produces vacuum which lifts the slides to govern the fuel.

The choke doesnt move anything in the carb, it allows fuel to enter the engine via the holes at the top after the butterfly in the inlet side.

Nope, coz B162M is not there

Try this one......... http://www.vsource.org/VFR-RVF_files/BH ... tCodes.htm

Your yellow may not even be a Honda one, so you could be back at square one if you buy the later model paint!

Take part of the bike into Halfords and get them to mix it to match.

HTH

If the starter is not engaging it could be the sprag clutch. I believe a few others have had the same problem, try a forum search.
