Mark Retrostar

It cuts out just over 60, only been at that speed for a short while. Started up on second attempt when stopped. Will check the items you highlighted. Project bike at the moment, back wheel out and rebuilding rear brake caliper. Going to fit new tyres whilst wheels are out. I think it is fuel starvation, so will add you suggestions on my to do list. Forgot to say that last owner took baffle out of the exhaust and it is running without one. Do not have it, so can't put it back in. Thanks for your help.

I have just joined the forum, so will have to get use to how you use it. I have recently purchased a Sinnus Retrostar 250cc which has been made to look like a vintage Triumph bike. Happy with it, but twice it has cut out at around 60mph and had to coast to the side of the road and restart. Thought it maybe fuel starvation as okay at speeds below this one maybe electrics. Has any one else come across this problem? Bike is a 2016 model and looks like it has been well looked after, only has around 4000 miles on the clock. Any help would be welcome Cheers Mark
