Indeed. Shame to get it all scuffed and dirty inside the engine really.

Would look lovely mounted and framed and displayed as a ‘talking piece’...

Not sure my 3 females would agree however...
 
Eddie, why would you put a motor like that into a Manx replica chassis ? Would it fit into a particular race class as a cheater ? - Otherwise I cannot think of a good reason for doing it. A Seeley frame would probably cost the same and would be lighter and handle better.

Before we start, will you stop talking about racing? I’m an ex racer, so I get the interest, but the key is EX!

Three simple reasons:

1. The manx chassis is bigger than a Seeley, which are freakin’ tiny, and I’m a biggish bloke.
2. I’ve seen and felt how good a good manx type set up can run.
3. Because I like them and, well, just because...!

Hi Nigel, looking forward to some torque figures from your 920, im getting ever so closer (very slowly though) to getting the 880 going.
6 x broken ribs and 1 x shattered scapula from my last racing round has slowed me up a bit!!!
Regards Mike
 
Whoa Mike, sorry to hear that, I don’t know that mate! When was it?

I’ve done a scapula before. I never got it set right though so now it gives me grief by agrovating my tendons there. My advice... make sure it sets right now Mike!
 
If ya ride some risks are beyond full control. Very rare do even severe local injury linger past expected healing time so usually turns out to be ignored spinal injury that takes some time to wear down from joint aligning posture ligaments damage eventually choking cord blood to inflame nerve paths to pain site, like a hidden snipper. Dr. hobot says wrap or tape rubbery magnets over direct injury sites and learn how to or find a clinic that offers traction & train in regrowing neck back to pretty darn good. Joints take 7-9 mo's or more to remodel - if doing corrective stuff, otherwise distinctly decays worse over each few seasons. I'm 66 with many severe injury form enjoying cycles, worst take like 3 yr not to be vunerable to some flair up but fnally resolve that even new injury is minor tempory annoyance between feeling way better that stupid young people.

Oh yeah if not eating enough bowls of heavy duty greens, grass and roots, bark, berries and seeds plus grubs and insects or chewing all the semi raw grissle off bone/joints then cracking em to suck the marrow out - likely should take lots of multi-mineral complex to avoid more bone minerals stolen to keep ya alive but still hurting and nil left overs to repair bone or connective tissue well. Btw 1st thing I ask new patients no matter what entered for is how their upper gut behaves as best indicator I know of for upper cord/brain stem issues being the priority to attend too.

I watched Wesley use him self up with bad foods and ignored my offer of neck training and mineral support so last year about this time, a series of exertions occurred to his upper and lower cord which then inflamed to shut down organs. I racked brain on what I could of missed when he limped in, as no dangerous pathological signs at the time. This mystified hospital Dr.s who did autopsy but no cause of death found. MD's usually only aware of bullets turmors, infections that stick out. He did not realize how bad he was as took over night delay for crest of inflamation to hit. His last ride could of used 920 power but said keeping WOT boiling on his '71 ex-HiRidder he could keep up with a hot to trot visitor on 1200 BMW. Said best thing he did was put on light alloy rims.

I can well envision using tire wearing zooms back to cruise speed after pretty hard braking for crests or turning blinds to enjoy the easy quick shove back to cruise or to confidently zip around some sluggish traffic w/o taking much extra risk than just sitting on a running cycle.

To me what's more fun than fast road work is fairly low speed stunting with right now rear spin which if 880-920'a work as intended should automatically occur to use grimacing restraint to avoid or cracking a tight grin practicing more of it.

I've given some thought to how I want power band, pretty tame low down off idle, decent low mid range for sane communing and tricky traction conditions of all kinds yet with throttle blips above 3500 making hook up or wheelie thrill limiters.

About only time frame matters is hard cornering under power or trail braking and rough off road play with heavy cargo not bee line zooms or in line braking for some smart old fart play.

if pain source is from beyond where ya feel it then magnets won't help putting them on area, and hardly anything locally done make much lasting difference, which is why so many prior resarch said they are BS, but fact is not good enough neurologist to recognize.
Sheeze some times I have to treat or send to surgeons d/t missed heart angina causing shoulder pain assummed to be from an old injury, which just makes more vulnerable but not the cause.

Doesn't matter what class, cheating or otherwise, but the one thing UK classic racing is really short off at the moment is Norton twins!
 
No twins class now Steve. Its been dropped, just classic up to 1300cc.

So you not doing much riding this summer then Mike ?
What are you doing for bores and pistons for a 880
 
Splatt, probably not over the next few weeks until I can at least get out on the Roadster.
next race meeting is the first weekend of February, have entered so better be ready!
If not I can always defer the entry fee to the next round.
I have a set of cast iron barrels that Jim Comstock inserted a raw set of 880 liners.
Piston are JSMS light weights, same as I have in my current race motor.
FA head and JS2 cam.
Regards Mike
 
Are the piston specials, 79 mm? , I have a bit of a dream happening in my head that needs to be put in to reality
 
Yes 79 mm
Probably as they took awhile to be supplied after I ordered them.
They are the same CR as my current ones 10.5:1
Just waiting on a crank to be made as the one I had on the bench had to go in the race bike earlier in the year.
In fact the race meeting I crashed at was the first outing with the new crank.
Regards Mike

Bugger! That means I rode in the last CRMC 1300 twins race! Making it even more likely I won't race with them again!

Best I get mine over there then !!!
Thanks Steve will look into it

See Chris' comment Mike, you will have to run with 930 triples! Though there seems to be fewer of those anyway!

For my part I will race in Belguim at least once and work on my French licence. Oh! and I will avoid racing against methanol powered bikes o_O

Better get that 750 of yours running again and come to Belgium! Your big banger will run as post classic!

Chris / Steve, if there are hardly any Norton’s, and fewer big triples, what’s the main contenders these days?
 
Steve A , mine is not on methanol, was on avgas, now trying 50/50 avgas/91 unleaded. There a lot of guys using methanol in my class.
Once my dyno is finished I will be doing runs on different fuels to see what comes out the best.
It is way easier buying fuel at the pump on the way to race meetings than having to borrow a fuel card and head out to the airport before each round.
