Dave Marriners latest build.

October 29, 2011 by mike.cox

Dave is well down the road with his latest build.

The CR project started by mistake when I bought a scrap 550 for a grand for the spare engine casings.
Turned out the motor had been exposed to the rain in its semi stripped state. So I took the lot for a bead blast and when I got it back I thought I'd powder coat the frame and hang it in the roof. The motor didn't look too bad either.
Famous last words and that's how it started.

 

First time at Redstar. October 2011

October 17, 2011 by mike.cox

Red Star.
It went off quite well. 22 members came and rode at this Northern’s track. With families as well we must have had 35 people there? We took every pit along the front.
 
I and I think most found the facilities clean, canteen very price competitive, a large well kitted out bike shop, toilets also clean, soap dispensers paper towels etc. plenty for kids to do what with a swimming pool and playground.

Cadmium plating.

September 21, 2011 by mike.cox

 
Technical.
Some of us do quite a lot or work on our bikes instead of farming it out. One area is plating.
Cadmium is a superior finish and far better then zinc or galvanised finishes. Even worst finishes are rattle-can spray finishes or even Humbrol plastic plane kit paint touch-ups.
 
You can send in and have it professionally done which takes a couple of weeks with the possibility of parts going missing, or do it whilst drinking a cup of tea.

As you can see the piston took a pounding.

Wheel bearings etc

November 17, 2009 by mike.cox

Technical. No 2.
Getting the wheels set-up properly and in line.
 
How are the bearings?
Fit the wheel to the bike without any brake assembly, or set the brakes so there is no binding whatsoever.
Spin the wheel. It should rotate for 1 to 2-minutes or more and never come to the same place when it stops.
If the bearings are shot or too tight, you need to fix this before carrying on.
Most new bearings are sealed, but the older models are not.

Valve Springs

Valve springs and installed height.
All those with two-strokes skip one page, but don’t smirk, check your reeds and clean your exhausts out with a small tissue.

Spark Plugs

November 17, 2009 by mike.cox

Most if not all bike ignitions are poor cousins of the car world.
Minimal energy to fire plugs was quite common on bikes from the year dot right up to the seventies bikes. Only then did CDI and other improved designs arrive.
Bikes need all the ignition help you can give them.
 
Apart from better HT coils and best quality ht leads, the sparkplug can offer increased spark energy if you know what to ask for.

Silicone for bikes.

November 17, 2009 by mike.cox

Silicone sealant as a replacement for paper gaskets.
If you do some research into this remarkable product you will find there are literally 100 plus different types, all specifically manufactured for specific purposes.
 
So is the product sold at hardware stores for general use, suitable for our bike applications?
