400 fse cam/valve clearances
 

Hi
Ive just measured the valve clearances on my bike and they are bigger than what the manual says, my mate says that if the gaps are bigger then its ok and that it's when they are smaller that u need to do something about them is this true?

bit of xtra info:
the manual says inlet 0.15mm and exhaust 0.25mm clearance.
my bike measures inlet 0.20mm and exhaust 0.30mm

i'm just a bit concerned 'cos if the worst happens i wo'nt be able to afford a top end rebuild.

Thanks for ne advice

Is it hard to start the bike?

You should try and keep the clearance to 0.15 in and 0.25 ex.
With the de-comp it is cridical to have the exhaust clearance correct.

On the early 400/450 they had some cam problems so check the shim
buckets and cams are not worn.

Bike starts fine, tho it can be a pain when its freezing.

I check my valve clearance when it gets hard to start when warm.

When cold my bike doesn't start instantly like when warm probably cause of air pocket in fuel line? My tank seems to be putting pressure on the fuel line which sits on part of the frame, it came apart one time on me and started squirting fuel on my leg when it came apart at the clamp. (need to re route it)

I try to keep a full charge on my battery with a battery tender.
