I get a feeling that the mixture screw should be 4 turns out?
That info may of come from Beta uk ssdt preparation list.
Try less oil on your filter. Often they are over oiled.
Unfortunately a lot of selfish fathers instil this selfish attitude in young riders. Often in youth national trials where times are tight you will see daddy holding the bike in the queue whilst little lad walks about in the section till the last minute so the rider can be onto his bike waiting at the front of the queue for him. Only the rider can get the bike round the course so this should be stamped out at an early age.
Something I had never really noticed in the past was the amount of wear on discs. This has caused me numerous problems.
Once pads were worn down anywhere near half thickness the brakes would be sticking on and binding. I assume because the pistons were too far out.
Check your discs for a distinct lip on the edge.
I'm have tried a new type IRC that isn't supposed to deflate.
Starting pressure on lap 1. 4 psi
Finishing pressure. 3.5 psi
Starting pressure on lap 2. 4 psi
Finishing pressure. 2.5 psi.
This was a rocky two lap road trial. Probably better result than older IRC but still far from acceptable.
I have now given the bead two coats of Tip Top bead sealer to see if it will help.
Lomax road trial on Monday will test it!
Paul rides a few trials still. And uses the same trials gear now that he did back then! Still tighter than most Yorkshire men could even dream of!
He does play golf more though.
The electric bike is helping to get youngsters in to trials.
Kids want something they can easily play a out with on the drive and garden at home. Petrol engines prevented that to a degree. This will only grow as newer and better bikes come along.
300 cc bikes are good enough to do world rounds. Some makes are pretty gentle but others are very powerful.
A 250 is more than enough to do any club or national trial in the UK.
A 250 you will control the bike.
A 300 the bike will control you.
The vast majority of riders have more power than they can use.
I did the SSDT on a 160 sherco many years ago and it was no problem. That's 100 odd miles a day on roads and moors.
There's a hell of a lot more Montesas about at club trials nowadays than compared to perhaps 5 years ago.
But they are mainly on the easy and middle routes.
No problem with doing whatever you want if it works for you. A nice clean throttle tube and handlebar with a little light lubricant is plenty light enough for me. There must be a point where you can make it too light and lose the control over the bars. Does it make it very light?
