Hey Luke,
was checking out your youtube channel, nice vids there. Can I ask how you got songs on them? I thought there was some copyright issue?

Born in '94, good year

Started taking apart my engine today, got it completely stripped down today and got a few things done.

Started with basically a stock engine - boyesen reeds, exhaust mod, lighting coils removed and nukaru coils.

Plan is
Get the crank welded
Get the crank/flywheel balanced
remove flywheel ring gear
get the head shaved 1mm
polish pistons, head, ports etc.
yamaha 70 carbs
D1 exhaust tuner
BR8 HIX plugs - Think these are correct for a shaved head?
Mikuni triple fuel pump (reliability not performance)

Here's the coils:


Here's the yam 70 carbs next to the standard D2 carbs:

They're the square bowl type. Very tight fit on the tohatsu! Had to shave a bolt to get them to squish together enough. Think these are automatic choke? Not sure how I'm going to the get that to work...


Another small problem - the 50hp carb bolts are too short, so I've had to order 90mm long ones.


I was speaking to fast fred before I started so I knew this one -

You have to use the link from the tohatsu 50 on the 70 carbs. The 70 ones aren't adjustable whereas the 50 ones are.

Another small job -

You can see the step at the back of the carbs, to take advantage of the extra diameter of the 70 carbs you have to open up the reed block.

Continued to strip it down, first time taking an engine back this far -


Pistons before polishing -


After -

Started wtih 240 grit sand paper then 500 then 2000.


The cylinder head got the same treatment -

Had a go at some mild porting -


Think I'm going to open them up some. The top one here is stock, the middle is after I smoothed it. They had very rough edges when I started and they're already much smoother, but not much larger. Thoughts on this?

Got the flywheel done, weighed 3.42kg to begin with, 2.96kg after. Not much less but all the weight removed was from the outside edges so it has more effect.

Just used a grinder to cut almost to the centre part of the flywheel, the used a hacksaw to finish it. Just popped apart, simple as.

(the tape is to stop anything getting on the magnets)

Job done

Gave the block a clean -


Used the parts washer first with Jizer then pressure washed them

Going to get some primer, not sure what colour to go for yet.

Looking a bit empty back there -

Got a first judge of top speed the other day. Raced a jetski that topped out at 55mph on his speedo & I must of been doing a good 3-5mph faster with two up & 20ltrs of feul.

Do you recon take the outer ring off the flywheel will make much difference?
