maybe bit of a long shot. But this bike was given to me by my father. Stould still for years. Got the carbs cleaned by local shop. Synchronised and so on. But stil does not run that wel. Ot runs nice on static and if you slightly open the throttle it does rev but once you fully open it it starts acting bad. Anyone can point me in a direction where to look at? Feels like it cant burn its fuel. ?

blocked fuel filter in tank ?

that should be cleaned by the shop. will look in to it. noticed now that the rear cilinder sparkplugs have a very weak spark ( yellow) maybe it is that it cant burn its fuel proper?

i was thincking of a test. take a blok of wood drill a hole in the centre and to nails that meet in the centre hole spaced 7 mm of each other. 1 side connected to the spark lead and the other to an earth point... spark should jump right?

So i made that thing with 2 screws in it spaced 8 mm out of each other. The sparks went from one point to another without a problem and were nice and bleu. Do i may presume that it are only the sparkplugs that are worn out? Since some of those give a more yellow spark.

I have experienced this before on my bike , it turned out to be knackered plugs , worked fine in a test but once under strain e.g high revs they couldn't keep a decent spark . Not saying this is the solution but it could be a possibility

i'll get some new ones tomorrow. needs new ones annyway.

so got the new sparkplugs in ( garage had put in different plugs for each cilinder. ) also screwed the pilot screw out and gave it a light rub but the bike does not perform anny better. guess shop did a bad job cleaning the carbs
i do can get it pretty high in revs giving it just a kwarter of trotle but the second i give it full it just gos down. it keeps running with the trotle wide open but more with a on of kind of way. ( 800 rpm up to 1400 back to 800 up to 1400....)

blocked jets in the carbs ?I know my bike if left for a while gets a really gritty deposit in th carbs and it blocks the idle jets to the point where it won't tickover , its quite tough to get out of the jet too . ,maybe they missed the mains or something .

drove it today just to show at a mate wat is wrong and when i put it back in the shed and wanted to show how it jumps up and down i got this... flames spitting out the exhaust instead of going up and down the revs?

cleaned the carbs and it is much better but long way from good. Still spits and runs bad in lid rev ( like it runs on 1 cilinder for a few seconds. Than pulls again in higher revs. Now i drove it a bit and took the sparkplugs out. Thr rear ones collor good the front ones don't while i have opend up the fuel a full turn more on the frontt then on the back. Thr front does not seem to collor at all. I'm out of ideas now. All i can think of is that it now runs on a batt of 8,5 ah instead of the original 10,5 or 12,5 ( cant remember exact) next is maybe a headgasket blown ( please say no) but i have no white smoke at all.

hmmm, some of the jets can be a bit difficult to clean ramie , are you sure all the jets in the front carbs are clear ? also is the air filter stock ..and no air leaks in the pipes to the carbs .

Old / bad HT leads? I replaced my old ones after similar problems. I was convinced it was a fuelling problem but was just luck that I saw an arc from the lead to the front cylinder.

Edited by PhilR on 20th Jul, 2014.

Pretty sure unscrewed them all for cleaning. Tought about air leaks... how to test? Ht leads are original from 97 but only have 8000miles. Stock airfilter but brand new.

15+ years is quite a long time for the leads. My HT leads we're also original from 1995 Resistance was fine, but plastic insulation was starting to age harden. Only had to replace the wire as the ends are screw on. Even if they still ok now, they are a serviceable part and they'll fail at some point, so for a few euros I'd change em.

what about air jets and other jets in the body of the carbs ? didi you unscrew the idle mixture screws and bast carb cleaner dow the orifices ?

Medusa + injection = too much torque for the dyno ..https://youtu.be/qg5o0_tJxYM

so update. new leads in (resistance on the old were still good) but the same trouble. carbs open again i i seen that the needle valve sticks up a bit when the ( dont know the word) plastik thing that gos up and down with the fuel) is not attached. ordered some repair kits for them. i'm pretty sure now its al down to the carbs.


what are orifices?

orifices are holes , when you unscrew the idle adjusting screws you are looking at a threaded hole ,spray the carb vleaner down it , it should come out of the little hole inside the bore of the carb ,somewhere near the butterfly .also it may come out of a hole at the inlet , block this with your finger to make sure it cleans the inner hole .
