TDR starting problem

[rolz82]

So same again today, was hard to start, once started it would idle fine then the idling would get faster on it's own? The gradually go back down, then it would do the same again, had it idling on the stand for 15 mins and temp was way over half way

@rolz82 does it have the expansion bottle in the rubber manifold between carb and reeds? Mine raises and lowers its idle on its own with that bottle, originally I thought it was an air leak and tried all sorts, once I plugged the axpansion bottle off it would idle perfect, but did lose abit of power so put it back on.

@glynn123 lol are you trolling?

@rolz82 clean the carb, check the reeds, check plug.

[rolz82]

I've checked the plug it was oily, I'll have to clean the carb tomorrow and check the reeds

@irongamer727 don't know what you're getting at, I'm referring to the boost bottle, think they called it the YIPS system. Stores fuel and air mix for throttle blips and high loads, hence why it raises and lowers idle itself as the pressure settles in the boost bottle. Also helps with stalling etc.

@glynn123 think it's called the yeis bottle ( Yamaha energy induction system) something like that

So my DTR never started without choke. That's considered normal for these engines.

@calum sometimes with a fresh plug mine starts without choke although extremely rare for me
