Jezzzzz, my ears HURT! the little fella is sounding SWEET ! just a little hesitaion off idle, sometimes, but once I get some serious heat into the engine within the next week during a test run,,,,
Oh yeah,,,,NO BLOODY OIL LEAKS , excluding the clutch cover gasket which had been on and off a zillion times the past few weeks, a newie will cure that.

Progress was halted yesterday when the fuel pump died, but the auto shop was open and gladly took my money in return for a new pump.
But,,,,,,,
Test run completed today, and it STILL GOES !
That's an improvement on last year, I just froze my nuts off @ 6.30 am and probably did 3 miles or so, moderate revs with a few 10 grand changes with a total of 6 takeoffs.
The important outcome being I seem to have cured the oiling issues that pulled me up real quickly at the lake last year.
Still have some carb jetting issues to address (pilot circuit) but I feel confident enough to now nominate , hopefully it wont cost me $1 per metre this year !

It sure is Rob, I spent much of the day looking for a new home for the fuel pump, and throwing the holley regulator back on, the bypass setup still leaves too much fuel pressure for the needle and seat to handle.
Finding spare spaces to mount the pump is proving damn near impossible, but maybe it'll fit between the battery box and the rear tyre, just to make fitting the battery more difficult than it already is (if that's possible)
Early night tonight I recon
The cheques in the mail

It's funny stuff this alcohol, all the tricks Iv'e learnt over the years jetting carbies for petrol just serve to confuse me when playing with Meth.
Yesterday,my biggest prob was a stumble off idle when blipping the throttle, once cleared, it responded fine, pulling like Glenelg tram @ anything over 1/8th throttle.
The textbooks will tell you this is the pilot / air circuit's job, and their partly correct,,,,but,,,even @ idle, with the throttle fully closed, there is still fuel bleeding through the main jet.
Here's why,,,,after hawkwinds lean condition mishap, the fear of melting something convinced me to up the jetting from #310 main, and #55 pilot, to #340 main,,and #65 pilot.( the bike ran fine last year)
While tracking my current prob, I went back to #55 pilot, leaving the #340 in, this helped, but the stumble was still there,,now, not having a #55 pilot and 'cost dropping the needle is an ablolute pain, I threw a #320 main in ,,,problem solved !
Now, if the main jet doesn't have an effect on the idle circuit,as Prof Julius Sumner-miller would say,,,, why is it so !

Tiny i melted 2 heads in the US this year, bloody methanol is unforgiving stuff ..... but does it go
going to give it one more try, better ign system to make sure it all burns and can run richer without putting out the spark
also learnt to index the plugs so the earth strap is not on the hot exhaust side of the chamber,and double washer to put the tip into a cooler zone
remove any edges that can cause a hot point in the head like the ridge between exhaust valves
Spare head arrives this week then it back onto the dyno

Now I dunno why he's been so cagey about it , but Tiny sent me some shots of his new bodywork, I don't know why he didn't just post them here, It's a good looking job, I just wonder that it may run a little hot, nice muffler though...it should be a "pearler"
ya see , he even went to the trouble of putting his name on the seat....what a trooper
