ZXR Sports Production Race Bike
Hi there, new to this site so if possible give me some help. Have a 'Hot Start' problem with my race bike. Starts from cold fine but when pull in after race for tyre check etc it will not start.
H model with L engine and SP cam. Everything looks ok on dyno carbs and power good. Running mid range Spark Plugs NGK CR9EK.
Have heard this is a common problem when the SP cam is fitted and not much you can do about it!
Any ideas greatly appreciated.

Not only can you ride a bike, you can fiddle with it ! Quality

zxr's 400s and 750s were known for hot starting problems, as robB says leave it to cool for a few minutes but i guess you don't have the time whilst racing?

that was the problem, the engine gets hot and evaporates the fuel in the carbs, are you using ram air?

you need to direct more cold air towards the engine which was the original purpose of the hoover tubes, just too much may cause the opposite problem of carb icing, does your bike have the heater tubes running beneath the carbs?
