Re: 665----667---------Neighbour's of the Beast
Ever had days when nothing goes right?
well, I did on Thursday, Friday almost as bad (doctor appointment, physical therapy)
Made several very small parts and managed to lose them, eventually made enough parts to make new throttle cables for both sets of VM carbs, (XS800 and CB378. )
Lost couple of sets of 'crescents' for cam sprocket holes so, after about 4hrs losing stuff, gave up and went to work
Today though, ever had a day when everything goes right, almost by accident, it still goes right ;D
Wife didn't want me getting oily in garage (we had to go 'visit' people) so I only got hour and half tonight
Made crescents for cam sprocket, took about 15 mins (from a 20mm bar.
)
They fill up the space where bolt holes got filed out to slots, sprocket can't move when engine is running (read reports of CB350 sprocket bolts coming loose and/or cam timing slipping)
It's not the correct way to re-time cam but it is less work than doing it correctly and, the timing marks 'almost' line up so there is less chance of getting things wrong in future (correct way is slot one hole only, advance cam one full tooth then adjust timing to where you want it, do second hole to line up with bolt edge on cam)
7mm outside diameter, 7mm inside diameter, 0.064" offset. 8) (this only works for my skimmed head)
dropped cam sprocket bolt Thursday, couldn't find it anywhere, today, almost stepped on it, it was just 'there'
Cam timing is now (at checking lift)
intake opens 10 degrees before top dead center
intake closes 34.5 degrees after bottom dead center
Total open = 224.5 degrees
Max lift 0.320"(not corrected)
exhaust opens 48.5 degrees before bottom dead center
exhaust closes 1 degree before top dead center
total open 229.5 degrees
max lift 0.310" (not corrected)
Surprising, thought it would be substantially more on intake than exhaust?
I guess that's why CB360's don't run as well as CB350's?
Not ready to spend $400.00 on a 'race' cam though, particularly as stock 'mild' cam allows 11,500 rpm
Normally timing mark is completely level with gasket surface, this one 'lifts' to left. You can just about make out timing pin at 6:00 o clock position lining up with factory mark on oilseal housing
How close did I set things?
this close
