Yes I did mention in my last comment I have done a throttle body sync/ start valve sync please excuse my terminology.

I do have some information about when I did my throttle body sync I noticed that it started really easy with no difficulty. When I watched other people doing the videos they had great difficulty. I then attempted it the second time round another day and it was really difficult I had to apply the throttle to keep it going. This is not normal could it be a faulty map sensor?

Thank you for your help. I am yet still to sort this problem. I think my next thing to do would be the throttle position sensor.

-Put it all back together I am going to take it apart again and re check everything. -I did check all the hoses and they seemed fine no cracks etc. put some silicone grease on them to soften them up a bit. -gt85 the linkages and pushed in and out to help lubrication they didn’t seem stiff or seized. -Funnily when I put it back together there didn’t seem to be any flashing of the FI it just went on and off as normal when I turned the engine on. do I need to reset it could the fact that it needs resetting be an issue? -when I got the bike (1 month ago) it had fresh oil on spark plugs so I replaced the seals around the spark plug and it stopped leaking. Cleaned up the plugs with some heat and put them back in. Apart from the oil they didn’t seem bad. -When I first got the bike it struggled to start first time. After emptying the tank of previous fuel I put in v power fuel and some redex to clean and it now starts first time just rough to start with throttle hesitation. -I thought it was fuelling issue but will come back once I have done further investigation. thanks for your support I didn’t realise forums were so helpful. Hopefully I get this sorted had nothing but problems with it since I got it. To be honest it has put me off Honda. I’ve had all major Japanese bikes and this is the only one where the issues keep coming. I am only persisting because of the lovely v4 engine sound. kind regards. Shane

Thank you for your help. I did what you said. When I start the motorcycle still it hovers around 1000rpm as soon as I touch the throttle it dies. I turn it back on it goes up to 1750rpm (warming up) after 2 mins it goes around 1200rpm and runs like a dream and throttle is okay. Is this normal?

Thank you I will try this and update you. Can I say one thing in the Haynes service manual it says not to dismantle the wax idle unit. Should I spray into without touching it or should I dismantle it? Many thanks shane

Could I have some advice. I have a 2002 Honda vfr800 vtech when I start it’s rough and when throttle applied it wants to die. After 30 seconds it jumps up to 2000rpm and throttle is fine. No issues after that I can turn it off and back on and there is no problem.Any advice or help would be helpful?
