Bottom line, is you can test for yourself but I would not use the 25t pulley with a 2mm split. Use the 24 as was suggested.
so do you recomend same size tyre all round for best balance?

If you run the 25t pulley, run the same size tire. Problem is most of the time people wear rear tires more quickly than fronts.

If you run a 24t pulley, try a 2mm split.

Agree, sometimes I use 23T with 3mm split when I need more steering. I feel the car could turn better with 23T for A main final and tire wear rate about equal front and rear.

thanks scott
i found when i tried the 25t the rear tyres didnt wear as much as they do when using the 24t and 2mm split.
seemed to have a little more steering.
i'll see how it goes when i run it tomorrow as they use vht on race days and it will change the handling
cheers
joe

The problem is the two speed shoe too closed to the upper deck connector, by cutting a little bit its rear section, problem solve.
I strip mind 3 of them in the first run, after doing this, never again.
P.S this method is I read from this previous thread.

There are many theories and urban legends developed here to solve this problem. Heres what I have done:

-Installed a monoblock
-Installed the aluminum upper brace
-Replaced the inner 2nd gear clutch balls with some bigger ones (S710's ball diff balls)
-Replaced the 2nd gear clutch shoes with the MTX-3 shoes
-Recheck your engine clutch ball bearings
-Decrease the gap that the clutch bell travels by adding shims inside the clutch bell
-Remove your first gear, do your mesh then install the first gear. (Without the first gear, both clutchbell/2nd gear should move freely.
-Change the aluminum pinions for some steel ones (they last a life time)

Hope this helps.

Default What's the matter with this car?

I am frustrated by this car with the constant stripping of 2nd spur gear.

I gave up running the final in my club yesterday because I stripped a gear in the qualifying and could not be bothered replacing it. This car blows the gear every 2 races, what the hell is wrong with it?

I've already done the following but the problem still exist.

Installed a monoblock.
Installed an aluminum upper brace.
Recheck/replaced the engine clutch ball bearings.
Decreased the gap that the clutch bell travels by adding shims inside the clutch bell, compensated with a tighter clutch spring setting.
Always removed first gear and meshed 2nd gear, then install the first gear. Installed 18/24 steel pinions.
Tapered the 2nd gear housing so it doesn't touch the clutch bell.
Shimmed behind the 2 speed shoe housing pin so it doesn't catch the aluminium brace.

What is the root cause of this nagging issue?

Can someone elaborate on the logic behind these suggesions?

-Replaced the inner 2nd gear clutch balls with some bigger ones (S710's ball diff balls)
-Replaced the 2nd gear clutch shoes with the MTX-3 shoes

-How about going to a 4 mm chassis? Is chassis flex the cause?

Thanks in advance for your constructive input.

if the 2nd speed engages too suddenly (or too late) the spur will suffer and won't hold the higher stress.........
