16.10.07 Gear Ratio Testing & Oil Flushing with Mineral 75W80
Belt Notes
The new Dayco belt seems too short as it sits about 10mm in the contra pulley even though it's a 747, & yet Shelley's belty is a Bando 747 yet sits well high on the contra pulley. Tried 788 from the Monza, & of course it's too long, but I can get an idea for a guestimate for a better fitting Dayc belt. Guessing a shot at a 760 might do the trick.
New oil
A little paddock ride & some revving.
Estimated K's 1.00
Flushed oil which had ali particles in it.....looked dirty.
New Oil
Ran the bike in the shed, & revved it with back end lifted by straps.
Flushed oil again, & still some particles came out.
Oil appeared airated, but OK colour
New oil
UpGear Kit in there which gives about 10% higher gear.
4.4g weight was alot of revving but topped 85 on the flat.
Accelleration didn't seem that dynamic.
3-Way Torque Pulley is set as race setting which apparantley in effect gives the bike another powerband as it holds onto a low gear for half the range then tips into higher gear.
Climbing the hill outside was over 75.
Estimated 4 K's
Flushed oil
New oil
6.5 weights the bike seemed over-geared with mediocre take-off.
Climbing the hill outside was struggling at 60.
Bike was getting hot....temp read 55C, but it is quite hot out there at the moment.
Flushed oil. Still getting fine ali particles though less & less with each oil change & increasing K's, There were a few small shards of steel.
Estimated 10K's
New Oil
5.6 weights feel more like it usually does on the road. Looks like 4.9g for racing. Reasonable take-off though it's missing that powerband lurch I enjoyed...maybe the UpGear has smoothed that out. Not really sure how it compares with accelleration....will have to ride with Shel to get an idea. Will have to get Shel to watch my variator whilst riding alongside me with my gearbox cover off, to see how far up the belt is at 80+....maybe she can even video it.
Temps were still high, about 49-53C, but maybe the old fuel & running semi has something to do with it, & it's still new rings & piston.
18K's done.....
Will do 50K's with this shot of oil. 100K's for the next shot. Then a track night on the final shot of mineral. Then after that will be fully syn.
Have to ride with caution, checking the coastability & temps frequently.
I'm bothered @ how short the belt is. It's a Dayco 747 length, yet Shelley's Bando Belt 747 length sits all the way to the top of the torque pulley.
Mine looks like it should be at least a cm longer. I tried the 788 from the Monza, & of course, it was too long. But at least I can gauge what Dayco length I can aim for if the same length numbers in the respective makes mean that Dayco comes out shorter.
