Well I took the old girl on her first ride today after a 14 year layoff....got as far as the end of the road:banghead::lol2:.She used to be a twin but now seems to be a single.Oh well back home to take a look at the rear carb again.I'm starting to think it's electrical though so I unscrewed the spark plug cap and found a pile of rust.Funny though as I was getting good spark when I tested the plugs.New leads ordered.I also noticed my plugs were NGK B6HS instead of BP6HS,"P" being for protuding so I bought a new set.I'll pop it all back together tomorrow and try the new plugs while I wait for the leads to arrive.
Cheers

No joy unfortunately.I'm getting a phftt,phftt,phftt sound from the front carby so off it comes.I also took the manifold and after market manifold "gasket thingy" off.This is the back one.

All looks good.So I'm peering down at the inlet valve and decice to turn the motor over by hand.On the compression stroke I can see small bubbles appearing around the valve seat so I'm thinking about taking the head off and lapping in the valves but first I'll nip around to a mate and borrow his compression tester.Bugger me,150psi in both cylinders with throttle wide open.This is with a cold engine so a warm engine "should" be better.Not what I expected at all.I'll fire her up tomorrow and see what I get with a hot motor.
Poor old girl.No wonder she won't run after 14 years doing nothing but I'll get her running good again.

Looks to me like you have the Mallossi Manifold mounting kit (http://www.mdinaitalia.co.uk/cgi-bin/commerce.cgi?preadd=action&key=0607004310) fitted which is a Very Good Thing; It is 'O' ring based not splitty squidgy plastic and I will be surprised if it is that giving you problems.

Having said that, it seems to be separated from the head with squidgy rubber gaskets. Weird. On mine, you can't see the 'O' ring, just looks like a small gap...

Are your sparks all good?

That's the one...I put them on in May 1986 @ 18,200kms.I write everything I do to my bikes in a book;).I suppose I should check how the O-rings are doing:rolleyes:.The front looked ok when I took the manifold off today.I've got plenty of spark but I did notice something earlier.It was one of those " did that just happen or not" things.I was playing with the throttle cables when I heard a distinct clunk as one of the slides hit the idle screw even though I hadn't lifted the slide at all.Checking the carbs I found that they were a long way out of sync even though I had earlier synchronised them "again".I know the cables were sitting in the top of the carbs ok so I'm wondering if one was sitting out of the twistgrip body and now that I had been playing around with it decided to seat itself back in.

Possibly like this ( I did this for the photo ) but can't imagine it has been like this since I dragged her out of hibernation....could it.

Anyhow I'll fire her up tomorrow and see if it has made any difference.

The other thing that happens with the Verlicchi twistgrip is that the cable nipple twists in the barrel and therefore sits higher that it should, putting the carbs out of synch. It doesn't happen with the Tomaselli though and I've often wondered about how I could fit a different electric start button in conjunction with a Tomaselli and lose the Verlicchi. Problems, problems!

Try this (http://www.ebay.co.uk/itm/DUCATI-848-1098-1098S-1198-1198S-R-H-Switchgear-/201168549774?pt=UK_Motorcycle_Parts_13&hash=item2ed694778e). It is what I was going to do on the GTS, which I converted to dual pull Tomaselli. I ended up using just a 3rd party engine stop switch as I didn't need the starter button...

You'll need to do a bit of metalwork but it shouldn't be too hard. I think it has a lug which needs removing and I think the bevel bars are a little smaller diameter hence you will need a spacer.

Thanks; that's the sort of thing that I've been thinking of, but I don't think that there is enough room on the clip-on for the extra switch, although I may be able to fit one somewhere else.

If i understand you correctly and you have fitted mallossi manifolds you shouldn't have a gasket either side. that's the point of the O ring. If you have 150 psi on the starter motor that is very good. its exactly what i would expect at cranking speed at 9.5:1. The psi is not that important within reason. , more important is that they are the same or withing 10% max. To calculate properly you need to know the swept area, the stroke of the connecting rod by the cylinder diameter (Which gives your base volume) over combustion chamber volume....or how many times bigger the swept volume of the bore is than the combustion chamber volume.

There's no gaskets Paddy,just the o-rings.I was surprised that I had 150psi in both cylinders as I expected a lot less in the front with the apparent valve leakage.I'm more than happy with 150psi.I won't be removing the front head with that reading.

I've got one of those.I had it on a 750 Paso when I put Dellortos on it.

When I bought the MHR I had 2 choices.The MHR and a Guzzi MK3 Lemans.They were side by side at the shop and I loved them both equally.The only thing that swayed me was the Lemans was white and I wanted a red one....and the rest is history,except for the Californis I had.I'd still like a MK3 though.

Well I'm not sure what I did but I took her out today for her first run in 14 years and she ran like a dream.I'm really thinking that it must have been a stuck throttle cable as pictured above.I could'nt believe it when she settled into an idle ( of sorts ).I still have to do a proper tuneup but all is good.I don't remember having so much trouble getting my feet up to the rearsets though:D,I actually missed them a couple of times and I'm still trying to straighten up:o.
So now for the problems,or not.The alternator light is staying on.This could be because I've been hammering the battery trying to tune a bike that would'nt idle but I would have thought it would have charged on the "short" ride today.I'll leave it on the trickle charger overnight and see what tomorrow brings
The other issue is the clutch isn't engaging until the lever is nearly all the way out.The clutch "is NOT" slipping and I'm not to worried about it yet but I don't recall the clutch engaging so far out in the past.I was hoping a run today might have cured it.I have put a master cylinder kit through it so maybe there's an air bubble somewhere in the line.I might "back" bleed it and see if makes any difference.

Unless the late ones have a different (proper) alternator light, the 'alternator' light is effectively a 'power' light or 'On' light as it is straight across the battery. It is not a charging light. it is an 'I'm here' light and bearing in mind they blow, the light being out also does not necessarliy mean 'I am not here'.

Andrew2
08.10.2014, 09:15 AM
My model ( the first I think ) did'nt have the alt light permenantly on like earlier models.I've fully charged the motobatt but won't be able to test it again until next week as I'm going away this weekend on the bmw:lol2:.When I get back I'll check all the connections before going for a ride.

Mine's a 900 Paddy but you're right anyway. The light should'nt stay on. It never has before.Cheers Andrew

Yes sorry Andrew, i tend to forget about the the 900 84 engine models, bit of a rarity over here. Nearly a mille give or take a few cc :) Not sure what the situation was over there but here we had Darmah bottom ends elec start, square case kick start and that Mille style 900 MHR's in 83-84. Your engine in 900 form was by far the best and most refined in my opinion of all the bevel twins.

Been a while but still here...just:). I've only ridden the MHR 3 times since registering it so haven't got around to sorting out the alt/reg light issue. I took her for a spin on Sunday and the light did go off a couple of times so I'm thinking it could be a dodgy connection somewhere. The battery is keeping a charge no problem.

Hi Andrew,

The one below has been lodging with me for the past few weeks. I was re-commissioning it to get it back on the road. Passed the MOT test this morning and I delivered it back to it's owner (the long way round). I have to say that with 15% less weight and 15% more power than the GTS it's a very different riding experience!
Are you in the Facebook Mike Hailwood Owner's group run by Al Harper? If not I recommend you join it. Al runs a fantastic group and there's a huge amount of knowledge and information there. And he lives just up the road from you in Sydney.
Cheers,
Derek

Hi Derek,
I didn't even know there was an MHR group....and what's Facebook??:lol2:. Thanks, I'll look it up if I can work out how. How long did it take you to straighten up after riding the MHR?. I had forgotten how uncomfortable it was or maybe I'm just getting older. Did you notice if the alt light stayed on when you rode it. I'm sure they did with that model but could be wrong.

Hi Andrew,
The generator light does stay illuminated on this 1980 bike.
Actually the riding position was not too bad - much better than the 996 I had last year. I sold that as I couldn't adapt to the riding position.
Honestly you should joing Facebook just for the MHR group. There's a whole bunch of them around Sydney. It's a closed group that you have to apply to join before you can open it. The name is "Ducati Mike Hailwood & NCR Enthusiasts Group" and it's excellent. Al Harper is already looking out for you!

Hi Derek,
I applied to join today right after reading your post. Well I think I applied. There was a button that said "join" so I pressed it and then.....well....nothing really :dunno:. It just disappeared and that was that:lol2:. I'm on a couple of other facebook forums ( I think) so I'm sure I can work it out.
I find I keep missing the footpegs when I ride her. I swear they weren't that high 15 years ago:lol2:. It does feel good to ride her again though.
I went to the Barry Sheene Festival of Speed last Sunday and had a great time.Freddie Spencer and Maria Costello were guests of honor and Can Donald was sharing a pit with my mate ( or maybe the other way around:D) Here's a couple of photos I took.
