Northcust becomes UK/EU distributor for Tuneboss ECUs \o/

Ok so I’m quite excited about this. It’s been in the works for coming up to a year now but till we reached a particular point where we were both happy, I’ve had to keep things kinda under wraps.

Several years ago, sparked off by a conversation with Legend of Legend’s Garage (who used to do a fair bit of R125 stuff), I learned about Tuneboss ECUs, which seem to be quite popular in the R125 racing community (in europe anyway).

I got in touch with Tuneboss but since the previous ECUs were a limited run there were simply none to be had.

3 years pass and then I get an email asking if I’m still interested in buying a few ECUs. At the time I was just looking to buy 2 or 3, mostly for my own usage but perhaps for a few other friends if they were interested.

Either way, we got chatting and things escalated and whilst the UK/EU market is small compared to the Asian market, they wanted to have a presence here.

Finding crankshaft balance factor on YZF-R125

going further down the crankshaft-rebuild rabbit-hole and getting on with the crankshaft rebuild for my new motor…

In this video we’re looking at trying to calculate the balance factor for the old 125cc setup vs with the big-bore kit, to see if that maybe explains why it’s run a little differently since going big-bore.

The logic is based on this video from 2StrokeStuffing (thank you!): https://www.youtube.com/watch?v=0hoE_…
