i only wanted to go to rockingham this weekend to end the summer off in style and give the hybrid a good thrashing-all i had to do was sort some jetting issues with the jet kit i had on friday and load the van and go- how hard could it be?.i didnt make saturday as the hole in the power above 9000rpm was horrible-not a problem on the road but on track it would have been hideous,there was a nasty flat spot as the motor came fully on cam.on saturday i tried every jet and needle combination in the known universe but to no avail so that meant that sundays trackday was out as well.during all the testing (the road by my house) i also suffered the embarresment of running out of petrol and having to push to a freinds house and beg for some gas as i had left my 3 children on their own with the words"dad will only be 10 minutes" to see if the bikes ok and wanted to be home before my wife came in from shopping and saw what my child minding skills were really like.i rebuilt the airbox.checked every lead and electrical connection,checked for air leaks in the airbox,exhaust,carb rubbers-everything you could think of i checked,rechecked and finnaly gave in and rang the samaritans who said"that will teach you to ruin a perfectly good motorcycle" which by that point i had to agree.any way,by this point i had come to the conclusion that it wasnt the fu*&%ng fuelling after all but something else that would probably be very expensive and probably terminal as well just to punish me for having the nerve for interfering with a perfectly good motorcycle.so i tried to change the plugs as they were the ones the motor came with as i forgot to change them as they could have been donkeys years old.but now the motor sits higher in the frame my plug spanner fouls the bracing between the frame spars-no problem ill just shorten the plug spanner and drill some holes in it,which i did and now its too short to get a purchase on to unscrew the plugs so i had to drop the sodding engine to put £24 worth of cr9e plugs in which i now know i diddnt bloody well need.with the plugs in i thought before i put it back together i would take off the flywheel cover as a last resort and check out of desperation and guess what-the flywheel had cut one of the three wires in half no wonder it wouldnt rev out so a quick session with the soldering iron sorted it out,throw it all back together,put my leathers on and it fucking pisses down- i must have been adolf hitler or dr shipman in a former life to deserve all that and just to think if i had taken the flywheel cover off on friday this post would have been very different telling you about two days on track and how well the hybrid went.oh well-we dont do these things cos their easy-we do them cos their hard,cest le vie

s'not just me this shit happens to then ?

ahh well, its fixed now, and just think .. had you fixed it friday, this could have been a "highsided my bike to bits and am in hospital for 3 weeks" thread.

chin up :)

thats the first thing to make me laugh in 4 days-thanks zim!

At least you found the problem.

The forcast is good for this weekend

Headaches, oh yes!
Fustration, been there!
Stress, absolutely!
But when all runs well its soon forgotton. Its so worthwhile.
Nothing ventured, nothing gained

... and we are talking about a 90% gain in power .... sweet !!!

ive calmed down now,its just that ive sampled 80% of what its capable of and desperately want to be able to give it a good seeing to(ooer!) and ride it with it working at 100% cos i know that chassis and 80/85 horsepower will make me smile so wide that i may be in danger of swallowing my own ears.cant ride tonight as the wifes working late but tommorrow better look out!!

Cant wait to give mine a good spanking on Friday (ooer)!
Good weather forecast! Cadwell park, life is good!

its now running ok after alot of messing about and i ended up with 115 (118 standard) main jets,needle clips at the top(weakest position) and mixture screws 3 and half turns out and it now pulls smoothly from the bottom of the rev range to the redline with just a hint of fluffiness now.so until i get it on the dyno and have a look at the mixture and the power curve im going to leave it alone.one interesting point is that it much prefers the 3tj intake trumpets to be pushed over the 600 velocity stacks like in a standard 400 airbox,it seems to give better midrange and a more linear power curve(by the seat of my pants anyway)so ive left them on.its a hell of a thing and ive fallen in love with it all over again and ive forgiven it now for its bad behaviour-a true street sleeper!
