I have been out of the scooter loop for a little while and i am ready to get my engine built again. But I have a easy/hard question. When the last time I bought the crank for my engine I bought it from Walter when he has his shop in PR. I forgot the name of his shop but anyways it was a +4 crank and a 180cc "power kit,' per his instruction I had the piston milled down so I did not have to run a spacer. Lon g story short, I am looking to replace the crank in this rebuild. I do believe that I did not install it correctly and it cause a lot of problems. I want to go with a berrter quality crank so I am looking at Taida. Is the 61.3mm crank a +4 or is it a shorter stroke?

Assuming you have a GY6 150cc, it's actually a +3.5!

While i dont sell Taida contact David Bullock. He is the master when it comes to Taida and has all the parts. his facebook is www.facebook.com/david.bullock.3785. Nice to see you around  PS: The old shops name was Scooter Elements. Walter |
