Drat!

That's a bugger, wanted to go up this weekend and test the bike.

I'm told it's fixed. No more wobbles, fade and bottoming out;)


Is the 5th September really the first time we can get on the track??

Oh poor guy, I'm sure there is something else you can complain about!!:twofinger :twofinger
Seriously, for your sake I hope the problems are gone though.

Well champ, the bill probably!!!

I don't know what they have done, but they did mention flying brake parts in from Aus so I hope we're talking seal kits only.

It seems all my woes were down to sticky pistons and I hope they're right! One or more of them weren't returning properly. Not sure how that caused the vibration but certainly pad wear and fade seems logical.

That being the case, then here's a list of things I didnt need to buy over the past two months or so:

1 x New Disc
1 x Set wheel bearings
1 x Head stock bearing
4 x Sets of pads
18 x Gallons of brake fluid

The good news was the front suspension, nought wrong with it. I'm afraid the bottoming out was down to poor setup. I only have myself to blame!

As a bonus, they found some minor stuff with engine. Valves needed adjustment badly as they well out of spec. Pots 2 & 3 were being fed treakle instead of fuel mixture which wasnt helped by the overgenerous fuel map I had downloaded from the web!

They say they've re-calibrated the injectors from 'cake mix' to 'fuel' but even so, the map was a bag of wank and I have had to promise never to be smart and try 'shot-in-the-dark' mapping again.

The vibration was when you applied the brakes, right? So it was probably due to the pads not being forced equally and squarely against the disks, either because they were sticking under pressure or because of uneven wear caused by not releasing properly.

Isn't that what Boycie just said Trevor......

Ladies.....ladies....please!

I think the proof of the pudding will be on 5th September when its gets ragged around the track. If the vibration goes, then I'm happy to notch this one down to sticky pistons. If not then carry on....!

You may want to talk to Armand Ali (7) about a similar problem- it really sounds like a set-up issue.

His bike was so hard that when I jumped on it I almost squashed me nuts- and I'm 20kg heavier than him. He was complaining that the bike was running wide out of Turn 5. His mechanic backed off all the settings- preload, compression and rebound all at once mind and now the front is really chattering on heavy braking although this has cured the problems on the other turns. Previously he used to brake at 150m on the front straight without any problems.

I told him that if the chattering occurs in dynamic state (change of acceleration), ie when feeding in the brakes it's most likely an issue of damping. However, if it happens when the suspension is settled down on a heavy braking section like turn 1, then it has little to do with damping as the suspension will be on the spring.

He is fitting a full Race-tech damping kit front and rear and changing the springs to suit his weight- you may want to ask him to see how this fares unless you have already done the same in which case he will probably want to hear from you!

Oooops sorry Bullet, just called Kumar and it seems that there is a private session all day on the 4th Sept. followed by drag races in the evening. Unless you want to practise your quarter miles and shag your clutch plates to get better race starts...

Well...

Not that I am a set-up guru boycie, but the vibration may well have been the headstock. I only learnt this the hard way, after complaining of serious vibrations under braking, and then being thrown from the bike at Gudang.

Turns out the first diagnosis of a dodgy disc/stuck piston were all crap - the headstock bearings were completely fukked, a point that was completely miseed the first few times I complained about it. Caused by too many wheelies apparently (not by me I hasten to add) Just my :2cents:

So how are you all?

Finally got my bike this week. Took it for a careful ride - Can't wait to get it to Eastern Creek, then off to PI to see Dave....:D

I doubt that a whole day track day is going to be on the cards because of the cars in the afternoon. On top of that how many people will pay RM180 for a double session and do you really want to do 20 laps at 2pm in the sun after a morning session?

Mind you I suppose it will be good practise for Round 5 & 6 but what will I do with my suit after, burn it? :hurl:

What about extending it. Starting at 8 o'clock and lasting till 1 in the afternoon, charging some extra for that.

Starting early is no problem as long as there are enough takers. Let me chat to Kumar to see if we could get an extension.

How many would be interested in starting at 8am?
