Hi Vince

YES it was definitely worth the wait and the $$$

Its been too hot here to ride everyday but I have had a few good runs and its a different bike.
The new rear spring and ride height have made a huge change to how it corners and I already thought it was great but we ran out of time and $$ to strip the front forks and fit heaver springs and oil and now with more weight on the front end they are are now the weak link ( excluding the rider )

Now that the motor has been checked and after the dyno run I find myself redlining a lot more but mine hits the limiter at 11,000 not the 11,500 on the clock anyone else have this

The combination of the ignition advancer and all the carb set up and airbox mods have made for a nice fat smooth power delivery

We changed the jetting and are now back on 95-98 octane gas before I had to run on 91

The only problem apart from having to re tighten the bodywork allen key bolts after the first proper run was when it started missing and not running clean one day last week, I was giving it beans to try and clear it out when I noticed sparks below the clocks
The battery leads that cross over had rubbed through and were shorting out

This is my SMACO quick fix till the next time the bodywork is off its now running strong again



Only got the bike back after my mechanic worked through to the small hours to finish it after the dyno run, he packed up his van and drove to the other end of NZ for the first round of NZ Superbikes arrived a day late no practice had to start off the rear of the grid battled through the field to 5th had a great race and then had his front wheel taken out trying a pass, down he went broken kneecap
Sad end for a real top bloke who lives and breaths his racing and stayed behind so I could have my Bimota back to ride over summer.

The rev limiter on that engine is actually under 11k rpm, think 10500 from memory, but OE tacho's tend to read optimistically. The tacho may be used on the 750 too, not sure if the SB7 used the same clockset, but your limiter isn't cutting in early, just the slightly inaccurate reading of the tacho.

On the Dyno, it show's up a lot more, some bikes tachos over read by quite a margin. I believe Yamaha had a few issues when they claimed one of their bikes rev'd to something like 17k rpm, but in truth it was only about15k, it was just the tacho telling lies.

Years back it was the done thing to run the 1100 on the 750 ECU to extend the revs a little, but not sure which 750 it was now that we robbed the ECU from.

Yeah, never did it with a stock motor, and there is little point really as the motor has peaked and given it's best already, so all you'd achieve is to add a little over-rev.

Think it was a water cooled 750 we used the ECU from, maybe a WP, and it advanced a little more too, so made it a little shaper as the revs grew.

That’s really terrible about your mechanic…
That you don’t fix with flowers….
I guess you have to do your own maintenance in the future

He's not a flowers kind of bloke, nor am I unless I need some extra points with my GF
As for doing my own fettling I left school a long time ago to be a bike mechanic and found out I was shit at it
Just as well I found some thing else I'm ok at so although I enjoy watching you guy's pull your bikes apart in your man caves
I am happy to let a pro do the hard stuff and I will just wash it ride it and maybe adjust the chain

Working on your bikes is the best way to get to know your bikes. If you do simple stuff you'll soon get knowledge and confidence to do more as you go. If you know the bike well you'll know instantly if somethings not quite right.

Give it a go i recon... there's always plenty of advice on this forum, some of it's even good advice

Well its been about three weeks and a 1000ks since I got my baby back and I've been out riding almost every day

Today was awesome a 180ks of 2nd 3rd and 4th gear sweepers on a back road and not much traffic

The new set up is a bit firm in the rear so we might revisit the spring weight
and I still need to upgrade the front forks springs for something a little firmer but even so its great fun to throw into the corners

Looking at the weather in other parts of the globe I feel the need to get out as much as possible while the weather here is a sunny 25c to make up for all those who can't

I got the final bill for all my work so far and I can see why you guy's do it yourself with 44 hours of labour so far

But I'm happy to spend it when it all works so well and nothing falls off when I'm pushing on

The bugs were out today so my baby needs a wash



So it's all nice and clean for tomorrow
