@meatman, as you found out, the GDU cover has an O-ring so it can be used for many years. The only reason to change it is if it gets nicked or starts to crack. When you do change the o ring you will...

Radical has been studying the gear wear issues in the SR3 Gear Drive Unit (GDU) and released an upgrade kit to help resolve the issues. Take a look at it and make sure to upgrade your GDU at the next...

As standard they were fitted facing towards the inlet of the airbox. To be honest I don't think it will really matter if they are angled off to each side slightly, they just don't want to be backwards...

We have been busy with off season testing and having alot of success. We first completed 2 days at Monticello Motor Club, we beat the publicly posted track record that stood for 12 years! Obviously d...

Those are OEM Gen 1 Suzuki Hayabusa Josh.

@rjbender Morning Rod, they are a custom part and not made by Suzuki so not readily available unfortunately. Its Radical, Jenvey or RLM for them! Just to add Rod those trumpets Josh has are ones that ...

No problems Rod! Larger airbox is better to have. That is the standard set up on the trumpets - don't think you will get the long ones on the ends anyway but the order is not too critical - the SR8 ru...

@ meatman The Forum Search Tool is your friend... .. you are probably using the Motul 75W-140... others use the Neo-Synth 75-90... their are people that have used both and have developed a preference...

Jason, had the car out twice now and getting the hang of it..... You would not be disappointed. Braking and corner speeds are unreal, even compared to a GT3. Sure, faster cars all around in a strai...

G’day All, Thought I’d share this idea for those with OCD tendencies like me… I’m tidying up my brand new SR3 XX and was getting sick of getting copper anti-seize on me when working around each corner...

Yes Josh, that is the correct thread size.

@jwb Firing order from my MoTeC config: 1 fires at 0*, 2 at 180*, 3 at 540*, 4 at 360*, 5 at 288*, 6 at 468*, 7 at 108*, and 8 at 648*. The SR8 engine is a 72* banked V8, which is why the right side ...

I talked to the Hankook tire engineer today who said that the reason you should run your slicks in the correct direction for the first heat cycle is because there are structural elements that run diag...

Hi Ron. I don't have an answer to solve this but I would probably first check your scale accuracy and ensure they are dead level. After I carefully set my ride height, I am typically way off on the ...
