Hi Larry, Sorry to hear that you are still having problems with the car. I strongly recommend that you send your engine to one of the Radical Overhaul centers to be inspected. I strongly suspect tha...

@rjbender Here's another link to that sensor (same color too): Bosch Temperature Sensor - Race Spec (racespeconline.com) Note that it's available in two different threads. One metric 12x1.5, and one 1...

Problem solwed!!! The magnet in nr39 was lose. Now when its is changed its shift perfect. Thanks for all help.

@raider89 - the 40 hours is total run time - not load time, so you are right to be asking about a rebuild around this time.

No I do not think so. The previous owner drove the first two hours after the renovation. Then I drove two more hours. The problems have since come in the last minutes and have gotten worse and worse I...

@rlm-dan Lots of things to try. I have not had time to look at it since a week ago, so I have not checked spark plugs yet. I had not thought about the fuel, but it is possible that I selected the w...

Hi @jonasr1, Where are you located and who did you have inspect your gear box? Also how many total hours are on your engine? The reason I ask this is because the symptoms you are describing are often...

G'day All, Competed in the first of four Rounds of the Tasmanian Circuit Racing Championship last weekend, held at my local track, Baskerville Raceway. It's a 2km circuit and has a lot of really good...
