Saddo pt2... The 100 version

[Wrigsby1]

Not only did I become a wee smelling saddo with my R80RT ("The Insipid" copyright Mark Farmer) project but I bought another one... A scruffer R100RT Mono with plenty of history and a new MOT... It was West of Glasgow so I managed the whole trip in 36 hours with a return ferry trip totalling 24+ hours...
So for those of you who moan about a 75 miler to get a good deal and you "haven't the time"... I left Shetland 1900 one night, coach/bus to get to the bike 150 miles+ away from the ferryport and then rode it back to catch the same ferry back to Shetland...

It's 80% the same as the 80 but totally different as the engine is a cracker... 100k miles and loose and torquey... Will need a timing chain fairly soon but holds 80 easily and returns 50 ish mpg... Which is impressive as both the chokes were slightly on as the cables were too tight...

So now its whether I make a R80 stealth 100 out of the two or a bit of a done up rat 100 to overtake 3/4 of the Wasserheaders with...

PS One of the wierdest things I have spotted that possibly make it an ex-plodski bike is that the bolts that hold the handlebar clamp on are spot welded in position.... Is that an early HSE police mod to stop the riders adjusting the bars to an unsafe position...

Long Live the Fairing...

See what I mean about the 100 compared to the 80?

You need to change the engine sprocket at the same time as the timing chain or it wont last half as long as it should.

Mine's an R100RT too and I was thinking the same thing today, about how remarkable strong the engine is

All hail the glorious RT fairing!

Can't even get your name correct... Thanks for the tip re the sprocket as that seems to be half the size and do twice the work...

Rather than the 80 wanting to be over 4.5k revs or at anything over 40mph... The 100 will go from 3k and takes off at 3.5k... Easy peasy mid range just like a Boxer should be and even though it's a few donkeys down on the 1100's it shows some of the FI generation where the torque should be (apart from not giving you the odd cough to catch like my 11's were prone to)... You never have to really rev it and the five speed box works great with the power...

Try a 'heavy flywheel' RT... they're just wonderful

whats years are the heavy flywheel bikes then as I don't know ?

whats years are the heavy flywheel bikes then..?

Pre '81 had the heavy Flywheel; there were big changes for the '81 models (running 'till 1984).

Main points:- Nikasil bores, deeper sump, different Clutch, different air filter box, unleaded 'Heads, revised crank case breather, and much lighter Flywheel.

These '81 to '84 Boxers are reckoned to be the best, but I still love the feel of the heavy flywheel engine...

And the pre '81 bikes (although flawed in some ways), just seem to have a higher build quality.

Heavy flywheel engines are smoothest of all ..
imho the 900 is top dog..
Later lighter flywheel engines also suffer from crankcases made of a cheese like substance, hence all the bolt threads pulling out when you torque down barrels and heads.....
iirc the torque was reduced by 8ft/lb to stop it happenin g so often !!
