Hayabusa first crank problems
Got the oil cooler all plumbed in, filled up with oil and went to crank it using the starter wire and earth lead to a battery pack. The starter just
spins but won't turn the engine. It's in neutral, any ideas?

sounds like you have connected the battery pack up back to front. if you did, the one way clutch will simply disengage.
If it can't be fixed with a hammer then its probably an electrical problem.

then you need to check the one way starter clutch. try removing the inspection cover from the starter cover and turn the crank backwards. In this
direction, the starter should be heard turning with the engine. rotating the crank forwards should hear nothing. if you can rotate the crank in both
directions and you can't hear the starter clutch turning the starter motor, then you have a one way clutch issue.
If it can't be fixed with a hammer then its probably an electrical problem.

I've removed the inspection cover to find half a tooth missing on the large reduction gear that meshes with the gear on the end of the starter.
Put it all back together and now it does crank the engine but i'm worried about the half broken tooth.

I was sold it as a 2002 but i'm certain it's a 2001.

i would replace that mesh gear mate i wouldent take the risk off it knocking anymore teeth off that gear as the brocken bits could end up falling
inside the engine.

OK.
Engines prior to 2003 could suffer with a starter issue. Usually caused by a low battery, the engine could backfire whilst being started. This could
cause serious damage to the starter gear or in the worst case break the crankcases. You must check this out. Do not try to run the engine with this
tooth broken.
There is a modification that you can do to fit an anti kickback clutch without having to buy a new starter motor. Check out Big CC online. They sell a
kit and so do TTS and I think SBD. All of these kits will protect the crankcase against backfire but more importantly, if you spin the car and go
backwards, the starter clutch can destroy the starter. Using this kit will protect the starter as well.

You mean this? sprag starter
I've spent so much on this motor already another £220 is getting a bit much. Think i'll have a word with Yorkshire engines on Monday and
see what they have to say about the missing tooth. According to their site they gave me a 'realistic warrenty' with this engine,
i'd call a broken tooth realistic.

Yes that is the item from Big CC.
If you bought the engine from Malc then he should look after you. If this is the first time you have cranked the engine, then tell him what you have
found. I would take the cover off this weekend and remove the damaged parts. If you could photograph the damage, I would be interested to see it.
Anyway, we seem to have found the problem and hopefully, it can be fixed va Malc.

Strongly suggest you update to the 2003 and later factory starting system, anything else is simply a band aid on the problem.
The earlier systems will definitely self destruct the first time you spin the car.

call nova racing direct as that's who everyone buys the parts from to sell on like extreme engines/big CC.

All sorted now. The broken reduction gear was replaced but it turned out the main fault was a faulty starter sprag clutch. Malc sent both parts to
me and now it cranks as it should. Can't recomend Yorkshire Engines highly enough, thanks Malc.

I just thought I would continue this post by asking if there is anyway to identify the later type starter from the early one? I tink Malc supplied me
with a later starter on a 2001 but I am not sure??

Part Number for 99 starter motor is 31100-24F00 which then superseded to 24F01. 03 models onwards were fitted with 31100-24F10.
I think the part nos are written on the starter or at least the last part of the number. Hope this helps.

Thanks Cosmick, you truly are a wealth of information! I am fitting a sump baffle and wondered if you knew the main end bearing bolt torque settings?

Sorry dilley you have lost me there. Are you tightening the main bearing bolts i.e. the large dia crankcase bolts either side of the crankshaft or
Big end caps inside the engine. If you are fitting a baffle in the sump, you shouldn't need to undo any big end or mainbearing bolts.
If it can't be fixed with a hammer then its probably an electrical problem.

The baffle has come from extreme engines, and from what I can make of it fits under the 3 crankshaft retaining bolts that can be seen with the sump
removed. I'm not keeen on removing them them to do this as I do not like to disturb things that don't need to be disturbed!

OK. Check out the thread size of the bolts and follow the chart below
6mm Initial 6NM Final 11NM
8mm 13NM 26NM
9mm 18NM 32NM
10mm 28NM 50NM

And by fitting that sump baffle my friend you will invalidate any warranty with malc, try saying the mains are rumbling and my answer would be well
you loosened the mains bolts.

Well, its a good job I did really as the clutch bolts were hand tight.
