Hi Guys;

Something to look at:

This bike I did every thing myself except the head which is currently in for an o-ring and avgas conversion. Did the crank and spray job :D It has the 105 exhaust modifications, fixed airjet 1.2, 300 rhs 290lhs mains, mods to airbox a few addidtional breathing holes, q4 needle jet, runs on pre-mix and most important zeel ignition that gives it that little extra. Standard pilot and power jets.

Damn
I can't see it because we got such shite signal at the farm.
All I see is the brilliant blue sky and obvious warmth of the sun and my thoughts go out to our European mates right now.
Ed, I have posted it elsewhere a couple times, I found the 3ma made heat with std 17.5 pilot at low throttle high speed cruising. I have 22.5 in there and cleared it up more. I realise yours is a track bike and you have the TCT function to save you on the zeel so maybe nothing. Also my TZ is std with 20 pilots. Different carb I know but the 3MA sugo carbs which came of some japo's race bike had 35 pilots!
There might be something there to consider.

A bit  of the classic 3MA roughness through the middle, but It's going nicely at the top end 8). That long uphill stretch on the freeway looks like an ideal spot for plug chops as it loads the motor well and you can hold it flat for quite a while. Great stuff!

Spring feels a long, long way away as I look out of the window into UK winter gloom... :(


Still Smoking...

Hi Guys;

I will do some pics next year with the fairings on. I have sprayed the fairings myself. Busy re-building the motor see my other post. Have an oportunity to sort out the wiring now with all the other optionals from zeel engine maps and pv maps shift lights etc.

Temp gauge sits high compared to the 3ma's I've had/got.
