Happy New Year all,
With work and poor weather behind us i managed to fire all my vehicles up yesterday and took the Avanti for a Blast!
After upping pilot jet and tweaking there is no real noticeable power drop at low end compared to standard ( Dyno done b4 jetting change).
Gearing wise its running Li 150 4.99 ratio and pulls well in top gear from low revs and also a nice lazy ride in urban areas
Surprisingly the 4 plate std type clutch with special springs is coping well all though a little heavier on operation than AF 6 plate but does not slip at present.
Looking forward to the sprinting and rally season
Sash
TUNED AVANTI TT3 30+

May Update
The 4 plate did start to slip even with big bike springs in, however was using nipple type spider and it fused to clutch cam in end, so GP type casing is put on with 6 plate clutch. Was hoping to have Cyclone in but that will have to wait for now. Also put the inspection camera into engine for a look and all seems fine with no issues on plating, bridge or BGM crank.
Also took advantage of changing gearing to std LI set up 15 x 46 (5.21)to see how another tooth of front would perform
Only been local so far

all is good with engine and running fine built this July 2012 and thrashed it to be fair, only real hassles have been af clutch gave up at elvington due to poor manufacture had 50% area on lower pressure plate, slots in bell for clutch ears tapered and recess in teeth not deep enough. Ended up with mec crown wheel, surflex 4 plate with llw springs and holds power fine and easy on hand. 2nd major issue was exhaust, rear bracket snapped back from mersea and although Mr Francis replaced, it did cause other issues such as looser stub mounting, crack where tail pipe joins main pipe and main bracket has split. Other than rebuilding forks its still running sweet temptation is to push it further given its ability to shift heat

Thanks for the update. Mine is still going well too (Avignon and daily commuter use) but, like you say, the temptation is still there to muck about with it The performance is fine in standard form and me mucking about with it will probably result in me losing more than I gain (!) but I'm still itching to see this kit show what it can do in other roles/configurations
Cheers for now,
Adam

Rite we've had this beauty apart for maintenance and gotta say all is good with minimal wear to rings and bore also changed gearbox li 150 to af close ratio, reworked the af clutch so it actually works ( filing crown wheel slots and new lower plate as original one was cap from new and had approx 50% contact area) new engine mounts, rebuilt forks and wheels are perfectly in line after much tinkering last part is to rework exhaust flange as its so sloppy and a pig to seal, i have made up ones for rb franspeed with great success. The franspeed avanti pipe needs to be modified on pipe itself as stub end of pipe isn't perfectly round but hey I'll get there

Another year and mine is still running so well (that's done it) that I've not even had it apart to check ring gap, etc. The old 'If it aint broke' adage is the one that I'm sticking to
Done anything more to yours? I noted your 'tempted' comment (likewise) and wondered whether you'd given in?

After last years shootout and getting 4th in class I'm happy with it, handling is sorted out with no hands at 80mph so gonna leave alone apart from maybe a change of pipe to try and gain little mph. It's a tried and tested engine of 3 yrs now and raising the power further needs consideration of parts and time. I've been trying to get a rapido 250 motor finished for this year.
I'm always curious what others are doing and will have an weekend in summer for like minded people with top speed/hp challenge
