Posted by: @cirrusdriver The lap timer was working briefly until they updated the track in the PDM. ? Do you mean updated the track in the SmartyCam? I just reread your problem, and it sounds diffe...

I may have a similar problem, but if not exactly the same, it is worth mentioning here anyway so others know. I have two SR3 XXs from 2021 with the SW4 steering wheels, Aim GPS09, SmartyCam HD 2.2, an...

@rojid Something does not sound right. Maybe your torque wrench is fouled-up and trying to over-torque the wheel nuts. When I do this by myself, I just roll the car backwards a little while holding o...

Like Charley, I use a big 3/4 drive torque wrench: Mountain 16600 3/4" Drive Click Style Torque Wrench - 100-600 ft-lbs/b> It will help with someone on the brake but it is not necessary. One per...

Hi Clark. I plan to be at VIR next week also with my SR3. Looks like we could see some rain. I'll be in one of the pit lane garages -- let me know if I can help you with anything. See you soon.

Posted by: @motogpwerks I own the most expense Hayabusa in the world ,factory built race bike cost $250,000 back in 1999. What is the story on this bike? Can you post a picture or link?

I have several sets listed on the Radical Parts for Sale tab. I will reduce my price to $600/$500 (from $650/$550) -- for tires with 3 or fewer heat cycles/4 to 5 cycles, shipping to Continental US i...

You may be able to see a part number on that sensor if you take it out. I searched Bosch oil temperature sensor and found a few like the one below. You can use a thread pitch gauge and dial caliper ...

Posted by: @davidf According to race car engineers (e.g. Carroll Smith), the motivation to lowering the ride height is to reduce the amount of roll that occurs during a turn, thus reducing the amount...

This idea did not work out because the pushrods are too long to allow a ride height drop of 5mm. To get around that I would have to either shorten the existing pushrods or replace with shorter pushro...

Has anyone experimented with lowering the ride height of their Radical, and if yes, how does this affect handling and other chassis geometry settings? According to race car engineers (e.g. Carroll Smi...

The the silver ring in your second picture is the spring perch which is used to adjust preload and corner weighting. If there is some sort of set screw on that perch, it is probably used to prevent i...

@azwcat Very interesting. Has anything been said about overall service interval beyond the 40 hours run time recommended refresh for the new series 1500cc engines?

Posted by: @bill-snead Hello- Anyone have a recommendation on a good brand of tie down ratchet straps? So many out there. I will be using the hub tie down locations. Thanks! Hard to go wrong with Ma...

I found the problem and a reasonable solution. Posted by: @davidf It appears that either the valve or the slave cylinder has tapered threads which prevents the bleeder valve from seating/sealing, a...
