Loosing power ???

[Fazer99]

TPS was out as so I adjusted. Problem still there. Just had a mate pop over who heard the problem I was having and he thinks it would be worth changing the plugs and air filter as they are at the mileage range where they should be changed and although the plugs look fine they may well be breaking down especially as at higher revs where the problem is, he also pointed out that the air filter is not as clean as I thought it was. So going to order those parts and if still no joy I'll go through what you have listed to check Gnasher.


Thanks for all the help and advice, I'm calling it a day as it's getting on my tits plus I can't do anything until I get the parts. I'll keep you all posted on the progress ??
