Hi all,
Just finished fiddling and fighting with my bike to get a new rear tire inner tube installed... A job that will get simpler methinks the more times I do it.
It was nice to get some help from a next door neighbour - although I think he was more doing it to flirt and satisfy his curiousity about the bike that be useful
- still it was nice to talk to him.
I have also fitted up a new exhaust as detailed in the pics below - this is for a GEBE engine and instructions to make are as follows...
remove stock silencer from Tanaka engine and reverse so fumes blow out to the LHS.
Obtain 2 .140 exhaust elbows for model aero engine exhuasts (the largest they do)
cut the angle off one of these and obtaining a short length of copper piping (maybe an inch to two inches) of the same bore as the exhaust itself make up a joint between the two. You will need a slightly shorter piece for insertion into the angled end with that pointed towards the back of the bike
Attach the straight end to the tanaka exhaust stub - under the top strap with two cable ties to attach.
Take two lengths of 5/32 and two lengths of 1/4 brass piping and tape securely at both ends. (I've used masking tape)
Place a large cable tie inside a small size hose clamp and put this round the 4 pipes - do not tighten fully as yet
making sure that you have attached the tape *very* securely push one end into the angled end brass section - you are aiming for an interferance fit at this point - you may need more or less tape.. then use more of the tape around the joint (again tightly taped) to minimise loss - you dont want the hot exhaust blowing onto the belt.
Using the large cable tie secure the hose clamp to the the GEBE mount as tightly as is possible and then tighten the screw on the hose clamp till the exhaust is held securely.
Parts:
2 x .140/.160 model aircraft engine exhaust angles (heat resist rubber)
2 x small cable ties
1 x large cable tie
2 x 1/4 brass pipe
2 x 5/32 brass pipe
1 x small screw hose clamp
1 x brass pipe (suitable size to be slightly larger than Tanaka exhaust stub)
Masking or heat resistant tape
