RD250

 I posted the image above in closing weeks of 2017 on twitter to thank some sponsors and more importantly; to introduce my next stage of this project... ...Enter the Yamaha TZ chassis. Mounting the engine I have already spoken in depth about the engine in another blog entry so I wont dwell on the hows and whys here. I didn't have a TZ engine for my TZ chassis so the RD lump, in whatever guise it found itself, was going in this chassis. To make this work, some fabricating and welding of brackets would be required and seeing as Andy Green  had the exact same plan with one of his TZ chassis, we decided to do the job together at his garage. The RD***LC engine cases we were using would fit the front engine mounts with simple spacers, the back is the area we are interested in. The TZ rear mount is far too small and in the wrong place so we lopped them off (we are working two cassis remember) and cleaned the area up for welding. Some wide box section was then cut to a ...

Knowing what is going on with your engine is useful to know for diagnosis purposes as well as for how hard you can get away with pushing it on the track. With the addition of these new Koso EGT, tacho and a pair of TTO cylinder head temperature gauges, I will be well in the know at all times! *Spoiler*  By all means read this blog, it is interesting after all (I hope), but I wouldn't plan a build of your own based too closely on this bracket design. Maybe try this on . Mounting Much time was spent offering up different gauges in a variety of configurations to see what would work best, not only to look good, but to fit in the space I have available and present the information to me in a simple easy to read manner. All very important when buzzing round the track like a loon. I decided early on that I wanted all of the gauge faces on the same level. This would be tricky as each gauge was of a different depth. I decided to try making a backing plate out of thin sheet...
