On Inspection

Hello my tightfisted bretheren, Last time we met I had just finished on the dyno and had given it some death on a road test. I was very pleased with the build so far but the power curve was bothering me a bit. The shape of it meant that it was running lean at low revs and rich at high revs. I need to consult a tuning Guru at some point as to why this should happen as it is more usual to run rich at the bottom end and lean at the top.

Still not to worry yet, it was more important to dive into the gearbox and have a look at the issues in there. I needed to re-shim the end float and see what was causing the rattling noise as you change down. It will not come as much of a surprise to you say that i had knocked a tooth off third gear. I was taking a risk with an early pacemaker box which are renowned for a weak third gear but i did not think i was making enough power to bother it too much. I was obviously wrong and so replaced it with a li150 box which i had for a rainy day. I then re-shimed the box from a 1.67mm shim to a 2.25mm one which meant that it was a little on the tight side but it turned fairly freely and would bed in as i used the engine a bit.

Now while i am tinkering about with the gearbox, fellow blogger Paul Green is trying to put together a practice session for us poor scooter riders as the BSSO are on a months summer break and he was not very pleased with his last race times. So i have messaged him and think i will take the bike along and try it out. Roll on the 23rd of july.

Woof ya kipper its.......

TightWads Alternative Tuning (T.W.A.T)

Not much to put in this week as the bike is pretty much finished so we are going to tune the riding tactics. When racing into a head wind, simply turn around on the bike and you will have the wind behind you.

That's it for now, so tune in next week when i will be stealing 50 drain covers and selling them for scrap so i can pay for a litre of petrol.
