Drilling pistons on X11 - Setup ?

[andys]

One for Kev I guess

I've finally bought the drillbits to drill my pistons, so they will have 2 holes like the new team softer ones.

As i'm running kit X11 springs, what weights oils should I go for for tracks like Bury / Southport / Batley etc (grass, astro and bumps)

Cheers. Andy.

I THINK this is Kev's latest starting set up..

Rear
Red spring with compensator spring
middle hole on wishbone (thats with the longer shaft, may need lower hole)
Additional 57 hole in piston (standard one is about 57 also)
25-30wt oil depending on temp
Hubs high
Roll bar in short link (rear hole in wishbone)
wing forward no gurney- see picture
toe-in 3 degs
1 deg camber
ride height - 21mm (which is wishbone just below level)
max droop (measure with shuey mini spikes) - 45mm

Front
Spring - Yellow
Additional 57 hole in piston
Oil 30-35wt
ball joint done up on shock just showing thread
push rod turnbuckle - 34mm - mounted on top of yoke
top wishbone fully back (max caster)
ride height 19mm
max droop (measure with shuey mini spikes) - 40mm
Roll bar in short link (front hole in wishbone)
camber 1 deg
Slight toe out

Extras
Motor Tekin Redline 5.5 geared on 18/72
One-way shaft
Bumper cut down to improve ground clearance on landing jumps
Cone washers used on front hub ball joints to prevent them popping out of position

Hope that helps

I have a bit of an update to that but I haven't had chance to write it down yet.

If you haven't drilled your pistons yet I'm now running the additional 57 hole in the front and a single hole at the rear drilled out to 55. Starting point for oils with these pistons would be 32.5 front and 25 rear. It's probably worth carrying 22.5 through to 37.5.

Springs i pretty much run all the time are blue front and red rear.

I'll get that update sorted soon!

I've some older x10 springs, they are redish, sort of brownish red ! Are the x10 springs the same as the X11 springs? Also do you run the compensator spring front or rear ?

Cheers

[KevLee]

The x10 springs I have in the shop are identical. The only difference being that they are black... Not sure why yours are that colour..

Anyway, this is the order

Soft 6.5 turn (red)
medium 6.0 turn (yellow)
hard 5.5 turn (blue)

then there's silver that is extra hard but I wouldn't bother with that for outdoor

hope that helps

Nearly forgot, just run the compensator spring on the rear.
