@Calum always amazes me how much difference a carb can make to a bike, I always remember my old dt50r when I upgraded the exhaust from standard to performance how untuned the carb was to the exhaust, turned a nippy machine into an sluggish horrible mess

@markus-w thanks for this

@Calum ill bet You £7.50 it doesent 😂 no it's just a project bike haven't ridden it more than 10 minutes at this point

@SpookDog how it smells 🤣

@markus-w I had put the cylinder of a TZR125 2RH on my DTR,complete with piston using the DT's stock base gasket,did not mount the head.I wanted to take measurements to make a custom gasket in case I was going the TZR way and not the Athena170. Everything aligned like the stock,piston bdp was same level with the ports floor and at tdp was level with the cylinder.Put it out and started measuring the height of the cylinder and was the same with my 3MB and the Athena. Didn't do a full port map.

@Calum I didn't have 2RH crankcases to do the reverse measuring.I assumed that the 0.7 is from the cases.
I had the belief like everyone that was from the cylinder.
