This has been pretty annoying the past weeks. Whenever engine is warm/hot the idling and low-RPM is rough. When cold, no problems as in smooth.

What has been done:
1. Put in carb cleaner in tank
2. Spray carb cleaner generously into carbs
3. New plugs
4. Cleaned air filter

Where else should I look for ?

Carb's might need balancing.

Damn... then I have to spend $100ish for service or buy a carb balancer from carbtune.

Any other options to balance the carb ?

Can always compare the pressure with your tonque

Which carb cleaner did you use and how did you 'clean' the filter exactly?

Mine ran like a complete dog when I last cleaned my filter because I used filter-oil which didn't get on very well with my stock foam filter. All was fixed by chuking it into the nearest bin and buying a nice K&N replacement.

I also ran in through with that Motul fuel cleaner.

BTW, I wouldn't try and balance the carbs yourself...more of a specialist job that one.

This is true if you don't have a balancer. But it can be done. There are plenty of articles online that should help you make a decision which way to go.

where abouts in melb are you? I've got a carbtune so I could help you out with that ..... especially if you were to shout me lunch

not good to hear mate.... how much is a carb balance (and what is it?! )

the point of a carb balance (or carb sync) is to make sure each cylinder is getting the same amount of fuel/air mixture on each stroke by measuring the manifold pressure.

it's part of a normal service or relatively easy to do if you have the tool.

cool, thx Drooo!!!

I need to balance mine...

me too

I think playing with the mixtures left my carbs out of sync...

someone should organise a spanner day!

ANDROO YOU'RE A LEGEND ...

Where do you live? or optionally let's organise a CARB BALANCING DAY maybe at your place, mine, Dan's (housewarming & balancing??).

I live in Bonbeach (halfway between Mordialloc & Frankston) and happy to cook some indo food for you guys (caveat emptor ). Tools, I have plenty but no rearstand.

Maybe a ride afterwards ??

OOOHHHHHhhhh, I wanna come too, although, i think that you guys live a little far for me and it's COLD down there....
have fun, and the usual if it does go down: pics and report!!!
