Engine Builder

Post by johnu » Thu Jun 18, 2020 2:12 am

Ok so I contacted Ed at ev engineering about an engine rebuild and he is a year out on a total rebuild. He can do the Carillo rod for me in a just a few weeks but that would mean I would have to do the rest myself :shock: I could probably do it but I don't want to mess anything up and also there are so many different opinions on what should be done. My engine as I purchased it is a tr5mx with a 570 kit. What I want to end up with is a reliable engine to use for vintage mx, I am not looking for something fast (I already have that KTM350 sxf). Any suggestions on where I could get a rebuild done or is it doable myself if I get Ed to do the Carillo rod? I am in SoCal and would prefer someone local but I will ship the engine anywhere in the USA if needed.

I did mine myself with lots of questions on this site with good results and I’m no expert. My B50 is reliable and goes well you can see my restoration details on the forum the B50 is a simple motor easy to work on just take your time and do the mods recommend here.

You can contact West Coast racing if you don't want to reassemble the engine yourself.

Thanks Barry. I really think I should give it a go myself, I've built plenty of two strokes but have no experience with four strokes. It will be a significant savings too if I do it myself.

Try Raber's in San Jose. Lots of good British experience, parts and service.

If you are going to do it yourself then Rupert Ratio's book is a great help.

Other than assembling and truing the crank the rest is relatively easy.
