I recall the bike was plenty fast last time at Riccione... Is it faster even, now?
No, Its still the same as it used to be. Its been doing that since before Lostallo. But I had no solution at that time and was left to pray that it doesnt break at the wrong moment. In Riccione I used 8 spurgears, about one per run. Just seems to pass down to the weakest link each time I do a step forward.
Tightening the pinion less makes it fall of the motor. But I think it was just junk looking closely I saw its a cast not machined pinion.

Change brands of pinions would be my approach.

Hi Edi,

Its strange,because i would of thought 4wd touring cars put more power and grip through the spur gears than our bikes.??,and they dont seem to have much trouble in breaking 48dp spurs??

cheers simon

Edi, are you breaking teeth off the 48p spurs or chewing them up? I've never broken teeth off an HPI graphite spur, even with a 3-turn motor and no slipper. Or even with a 4S pack in my speedrun bike.

I think it is because the slightest mishap directly hits the spur gear.
The drivetrain hardly has any possibility to flex.
A 4WD has softer tires then the driveshaft, Differential then a belt and then it is
at the Spur gear.....enough play and twist to compensate hard hits from the track....

I had this when i tryed a motor on the swing arm, any small movment or twist in the swing arm stress the spur and it would fail after a while.

You use carbon plates clamped with spacers for a swing arm could be it just worn the holes alittle and your getting movent when i under load. You got alot of componants doing the job of what would normally be 1 machined piece, could be alot of things.

I doudt it going to be down to the power and grip the TC guys put more load though the gears then us on accelration and braking and they use the same stuff as us.

One thing we did used to do,with the 32dp spurs was cut a little bit of fuel tubing and put it in each screw hole on the spur gear then screw to the spur holder.acts like a bit of a cush drive......

It is very common to KP bikes, before they started using the slipper... Here's my KP09 (nowadays converted to KP10), using RW spurs. Inside those washers are the fuel tubings. from Formby Models.

Nitro's have the same problem with spur gear hitting the floor,Inside right hand curbs smash them to bits. A metal gear is the easyest solution, it add rotational mass but it wont be noticable, it will lift the wheels of the floor if it touch's, As for the belt they can fail just fun for no real reason or many reason, Im surprised if there failing every run or other run like you say your persisting with them and not swapping to chain.

anyway probily best not to take my advice as i cant stop my wankel stripping gears at the moment

Congratulations Edi und Thunder Tiger Team Mates !

Here some more of my/our Pictures from the German Open Indoor Masters at Friedrichshafen

The young boy in the Black Shirt is my son and also drived there :-)
I`m very proud of him, because he got up in 7-Minute turns from 6 rounds on Friday up to 16 Rounds on Sunday
with his 10 Years! He was only 2 rounds back from the most next drivers and the Girls in C-Final.....
I took the 7th Place in A-Final as the only one in A-Final with real Stock Bike Configuration! (>1900gr / 17,5t BL / no Front Brake).

I also made some videos, come up next.....
