Yammy Nouvo Rough Idle

[JimSiam]

I have very poor idle and the auto is grabbing and trying to go, the bike has poor acceleration to 15kmh then is fine, i have had to replace the carby diaphragm once before because of a similar situation, could it be this again?

[thaicbr]

yes. Are you using gasahol? was it a genuine Yamaha part before? I would take it down the Yamaha shop to get sorted. sounds a bit dangerous as is.

[JimSiam]

Gasahol, no one has regular 91 around here, not sure if it was a genuine part, it has always run rough a bit since I got it, it will also peak at about 98kmh.

[thaicbr]

the reason I'm talking about gasohol is that its known to bugger up carb diaphragms especially if they are cheap rubber. Better to get a genuine Yamaha part they are less susceptible to the gasohol. Also might need a carb clean and tune up.

No regular 91. jeez where are you?

now just got to find a yammy shop, wonder if the boys down the road with the race shop would be any good, they have one that goes not like a nouvo, has hole holes all over the body work, noisy exhaust and sounds like it revs to 20,000 rpm, well 10,000 at least.

[thaicbr]

if you want it to run like a bag of <deleted>. try the race boys. But from experience if you want it to run well and be to Yamaha spec find a Yamaha shop. just my 2 pennies.

HI

I had the same problem, i dont run gasohol but my nouvo was parked for a few months so they had to clean the carb, also happen on my big bike, its like tar coming out when cleaning the carb, dam_n petrol

Yeah even without gasohol the gunk that my bikes seem to get in them from the fuel here..

But I would NEVER put gasohol in any of them.. Sure sometimes 91 isnt easy to get but is the nuovo even suited for gasohol ?? Thought ours had 91 only type stickers under the seat ??
