Quote:I will double check the rubbers and clamps. With vacuum pipes, do you mean the ones from the inlets? The funny thing obout those is that if you connec these to the morgan carbtune, the bike will stop after a short while. then you have to put one of the pipes back on the vacuum pump. start it up and then reconnect the carbtune again. :unsure2: Is it suppose to be like this?
Â
'a short while'...how long ? If you disconnect the pipe from the pump then there's no fuel going to the carbs and you are just emptying the float bowls. Having said that it doesn't sound short of fuel when you rev it........but, you have also moved the tank, do you know if the tank filters (internal on the pipe connection) are intact, perhaps moving the tank has disturbed dirt which is now in one of the jets ?
short while = 1-2 minutes. When i filmed the video the vacuum pump was installed thats why only one instrument is active on the carbtune. Hmm maybe dirt but it puffs through both carburettors, so it feels like little bit unlikely?! What about the air/fuel mixture screws?Â

Maybe i should start a new thread...

My understanding is that without the vacuum line the pump isn't working. Then again i think i have read that fuel bypasses the pump anyway, even when it isn't running (but then why have a pump in the first place ?
Â
When I had the mk1 I disturbed debris in the tank and the filters weren't present...the pump diaphragm and pump valve got contaminated which gave similar results
Â
I would connect the vac pipes to the gauges and feed the carbs directly from the tank. but first i would check that the filters are fitted in the tank or else everything else will be a waste of time until you strip and clean the carbs.
I believe gas will get to the carbs so long as you have gravity on your side. When the tank is in place, even if your pump has gone bad, it will work until the fuel level drops low enough it can't make it to the carbs on their own. So if you are balancing your carbs, if you still have the tank connected, it may not be high enough to get fuel to the carbs without assistance from the pump. The only way I can really manage it on mine is with a separate fuel supply suspended above the carbs.Â

Someday, I plan to install T-fittings to remote the vacuum lines to be able to balance the carbs a little easier. But "someday" never seems to come . . .
Jet washed the whole thing, oiled chain and went for a spin to dry it off. Got a bit of water in right spark hole. Had to dry it out. Noticed oil dropping down the side stand, hoping it is just excess oil from chain.
Didn't do anything but ride ! Just returned from an 8 day, 3000 mile camping trip. Left San Antonio, TX and went through New Mexico, Arizona and into Utah. Had a short visit with family and then headed back. Last day was from Gallup, New Mexico to San Antonio, TX and was about 850 miles. Bike ran very well except when above 6500 ft and then it was low on power below 3000 rpms. Gas mileage averaged about 46 MPG with a low of 41 and a high of 51. It was windy most of the time and I ran between 70 and 75 MPH. Used a little over a quart of oil. This bike still brings a smile to my face ever time I ride it !
New Mich PR4s and rebuilt rear caliper. Prepping for my trip next week to the head of Columbia River (from Portland Oregon) in Canadian Rockies. The Banff and Jasper Nat. Park country. This on my Vivid Cocktail Red 1992er.Â

Looks just like yers, Bigmatt. Except not stock exhaust. Two in to one single Delcovic muffler.Â
Had a test ride on a Ducati Scrambler...it's nice and light. Surprised how well those tyres grip, really good fun chucking it around but no fun at high speed, I have a large frontal area......  Then got back on the 9er to ride home and think I like it more than the scrambler
Took the bike out for a decent run in the Peak district, then noticed a few drops of oil under the bike when it was parked up at lunchtime......ooops!
Came back home, and traced the problem to the output shaft (oil seal), so cleaned it all up, ready to ring Fowlers Monday to order replacement seal......
Still......an enjoyable day......and a chance to spend a few more pennies on the bike

What was your bikes recent oil consumption like out of interest ?
No idea fixitstan, I bought the bike last year as a non-runner, and this was the first decent run out on it! So it will be interesting to see what it does once this is fixed.....

I'm pretty sure that mine improved after changing the seal, which i decided to do after noticing the fresh oil behind the front sprocket, despite neglecting to lube the chain for a while !

Stay tuned !.
