How's the bike running after the rebuild? What did you have done?
Bike has been running great after the rebuild. I actually had the top and bottom end rebuilt after drowning it in a river. It basically deteriorated over time and started burning through oil. Doesn't feel as touchy on the throttle as it used to but I assume that was because of the SS valves that were put in instead of titanium.
Learn to do it yourself, with the tank/shrouds off it takes all of 20 min. It is very very easy. Watch this (go to 2:50)
Firstly, thanks for the vid.
I sacked up and gave it a whirl - checking the clearances anyway. Bought myself some feeler gauges and started pulling it apart.
The valves were way too tight! I checked each one about 10 times to make sure I wasn't messing up the measurements (I could still be wrong). Anyway here's what they worked out to:
0.076mm (.003") - 0.051mm (.002")
0.152mm (.006") - 0.127mm (.005")
From the manual they're supposed to be between (imperial values rounded):
0.100mm (0.004") to 0.150mm (0.006")
0.200mm (0.008") to 0.25mm (0.010")
To give you an idea of the gaps between the sizes of the gauges, they went up in the following order: 0.051(.002"), 0.076(.003"), 0.102(.004"), 0.127(.005"), 0.152(.006"), 0.178(.007")
OK so my question is, is this a serious problem? Has it been bad for the engine running on such tight valves? Strange that it has been running fine.
I guess I'll go get some pads and install -0.05mm(0.002") on every valve seat except the rear right exhaust
valve where I will install -0.1mm(0.004")?
It's been an interesting experience so far. I hope I am able to do it all myself.
