Having been unconvinced by superbikes as day-to-day transport, I just happened to be passing a dealer on my Hornet 600 that had a 954 outside. An hour later it was in my garage...

it was a littlle impulsive, £4k seemed cheap - its got 10k on the clock and smacked of having money spent on it as it has some nice bits: Arrows 1/2 system, PCIII, MIG rearsets, Sprint damper etc etc, so I took the plunge.
Now using it to commute into London every day it's a nightmare. I have open the throttle very gingerly to stop it stalling until it hits 3,000 revs and then it's off like a rocket.
I've trawled the threads and it looks like it could be anything including:

• A duff PC
• Dirty injectors (is that a big deal to fix? I'm mechanically inept)
• The wrong map. I've tried tweaking the mixture manually but to be honest I don't even know if it’s too rich or too lean that's causing the stalling as it runs great from 3,000 upwards.
• There is sometimes a mechanical clunk, like a quiet version of slipping into first gear and when his happens, the revs stutter. Could something be sticking?
• Just one on those things. Losing the HTEV means it’s really fluffy low down, which is fine apart from the stalling.

Other questions I have:

• can anyone recommend a decent rolling road and servicing in Surrey? I'm happy to pay for decent service but just don’t like being ripped off. I plan to put a road legal can on so presume its best to wait and do that before getting the fueling changed?
• If I gear it down, does it affect the speedo reading?
• As an interim, I want to increase the idle but can't find the adjuster anywhere, I thought it was on the left but can't see it, Can anyone help?

Any thoughts or help would be really appreciated as it's a bit dangerous and more importantly, humiliating to crawl away from the lights behind scooters.
Thanks a million in advance for any comments.

Well i am having a little suspension trouble out of mine i think. But with you, i would wait to remap the PC until you have added the new pipe. If you take a tooth off of the front, you will see a quicker speed reading, which will be wrong. You will actually be going slower than the speedo reads, and you will rack up miles quicker. I am not sure where the idle is, i will get back with you on that one. I havent had to fiddle with mine. But congrats on the purchase and welcome to the site.

If you think the PC may be dead.. unhook it and see how it rides.
Fuel injectors, easiest is to start with a GOOD cleaner. not the $2 bottle that you see in the gas station.
Like the other said if you gear it down the speedo will be off
I have no clue where your idle is (sorry)

[steven0367]

the idle adjuster is on the l h s behind the fairing, if you look just above your front sprocket it is located near the two hoses behind the fairing bracket.

thanks guys, idle adjusted - any hints on fixing the stuttering/low down fluffiness, much appreciated.

I've also managed to strip one of the engine mounting bolts. has anyone managed to retap or fit a helicoil without dropping the engine?

Go to Sussex Rolling Road. They will definitely help you out. They not in Surrey, but Sussex is pretty close.

great stuff, booked in for Sat morn, let me know if you want me drop them your name so they know you're saying nice things about them

[Gaunty42]

No problem. Good luck. There are some pretty good rides around there as well. Try the Long Furlong ride from the A24 to the A27, its a blast and the view is superb.

[Gaunty42]

How did you get on at SRR?

[plyons]

didn't get there, I found a stripped engine mount and couldn't get it fixed in time so couldnt redline it. Will try and go down w/e 21-22.

I've tweaked the map myself and it's fuelling fine now bar the possible vacuum leak. Do you know if a dyno would highlight that?

thanks as ever

[Gaunty42]

Sorry to hear you had a couple of extra problems. In answer to your question I don't believe a dyno would highlight a vacuum leak, although this may manifest itself as reduced HP.

[jhonda41]

to da org.... any progress?

[Gaunty42]

He must have fixed the problem and is now back on the road.
