A MINI REBUILD

A MINI REBUILD


A MINI REBUILD
What started out as “a few things to do” post Casper has now become a mini rebuild. First there was the
slow leak in the back tire. Sure enough a tiny pinprick right on the seam so a new tube and a new IRC to
replace the Michelin.

Fresh rubber goes on

The annoying Magicals got the heave ho and the newest Rockshocks arrived. They too seemed a little long
so I’ve shortened them by 1/2 and inch using the other set of ends from the Cub which I had to lengthen!
I have a feeling that the true Majesty or Godden frame uses a longer swinging arm whereas I’m still on
stock.

Not so magical !

Further inspection of SG revealed that the jumping chain which had clattered round on top of the sprocket
had taken a bite out of every tooth, so a new back sprocket goes on the shopping list, and of course that
means a new one up front as well. I have plenty of new chains at the ready but nothing to mount them on
until they arrive from BJ Racing.

The Dentist’s nightmare

Every tooth chipped

As Trialsmasters keep making sections tighter and tighter I’m forced to succumb and get round to using
that dreaded clutch thing which would have had my trials mentor turning in his grave and rapping my
knuckles with his ash twig. However as most of our trials are in the dry I’ll give it a go with a new soft pull
lever and join the “clutchers”.

The “gold plated” chain tensioner block turned up from Lewisport  so I can fit that while I wait for sprockets
and other goodies. One of the strange things is that tensioner blocks ALL have the same fitting with hole
spacing the same as on modern bikes as it is on the old Yam. All that was needed was a little Makita work
to reshape the arm where the block connects.

Ready to fit

The Rockshocks had the shorter ends fitted and were mounted on the lower Majesty posts. The wait time
for the BJ goods has now become excessive waiting on the new engine sprocket so I told them to send
what they have and then I can start as the front sprocket is very useable unlike the back one!!

The Rockshocks go on

Wednesday, 24th October, and the new rear sprocket arrives along with the “soft pull” lever by Moose. I’ve
been using a similar one by Moose on the Cub so I’ll be interested to see how it alters the feel and action
on SG. Only 2 weeks left to Roswell so amid all the other fall activity of wood gathering, pool playing and
winter garden prep better get on before I’m shut down with snow. Really need to get this buttoned up this
weekend and get some ride time.

53 new teeth join the battle

My mentor’s worst fear

In other news I see my fabricator Ray has the Enfield up for sale on the Bay and the bids suddenly shot up
to $8000 when a bidder placed a bunch of test shots at the Reserve price!  We both noted during our chat
on the subject that the prospective bidder has ZERO ebay transactions so this one could be another scam
…..we watch with interest.

Meanwhile the “gathering winter fuel” game has begun in earnest and 4 Cadi loads have been collected
and stacked and by my calculations another 4 should have that mission complete and Brenda can burn
all she wants. The Shade Garden gazebo WILL be taken down this year to avoid the destruction by snow
falling off the roof……. we learn but slowly! Full weekend planned in all departments and school has this
Friday and next off so 2 three day weekends and no excuses!

First load of wood collected and stacked but as I set out for round two it starts to rain so the project gets
the CNX and now its time for bike building. The new parts are laid out, sprocket goes on and time to put
the wheel back in. Interesting to note that with longer shocks fitted, and with the wheel fully forward the
tire just touches the lower frame rail ? Well of course under compression this will move away but still not
a lot of clearance down there. While the wheel was out the spindle and hub were polished and greased
before going back in.

Time to get chained up

Wheel in and the new 428 chain by DID goes on, it gets cut to size and the split link pops on …… but the
fish plate will not fit ??? Yes, the link is good but the fish plate is incorrect being the same as the rest of
the chain and not a flat sided one ??? Put the used plate on from the old link and all is good until I do
the old rotation test looking for fouling and tight spots which can happen with new chains. The chain just
touches the spring on the Rockshock so that comes off and spacers are fitted behind the shock. All put
back and seems smooth enough……… but then I remembered a similar incident when I tried to fit a DID
on the Cub. Those that read the Cub saga will remember that DID chains are WIDER than RK and the
rest by about a fishplate’s width !

These DID chains are a fishplate wider

Fit a new RK, cut to size and everything seems better. Upshot of the story is I now have 2 DID chains
in 428 and 420 that I’m unlikely to use. Moral …… stick with RK.

Arse end complete, new tire and tube, sprocket, shocks, chain and the
bright yellow tensioner

Upstairs and time to fit the new Moose clutch lever in place of the Magura. Cable goes in, and a note for
anyone wanting to use one of these, make sure that the adjuster barrel slot is turned away from the line
of pull or the cable will want to pop out of its slot. The Moose lever cover protects the cable end from grot
ingress but leaves the cable and adjuster uncovered so I’ll be looking through my box to see what I have
in this department.

Is this the maiden’s prayer ?

Well that about completes this phase apart from testing and minor adjustments….will I notice any major
improvements ? Time for some testing and a bit of clutching !
