31K pistons because thats what Norbo donated.
We will leave the airbox for now and see how it runs.
I will update on start up and jetting as its trial and error with this set up.

Looking forward to how it goes!  Think the 400 airbox rubber tube would be good if you can fit one, it is closer to 400 than 250 now! You just need to remove the top airbox to change that rubber bit. Good to watch your fun and wish I was down there to run it in!  Cheers

Nice job and well done to all those involved, I was round Pauls at the weekend and Project X looks well ready for the summer.

They are jap pistons i used. They have big port holes in the back for better pick up and they are the best ones for the job before you go in to real money pistons like forged pistons etc.

Tomorrow is the big set up day.

RDnuts will be around my workshop by about 10am and we will set the timing to 3.5mm BTDC and set the Zeeltronics to Curve 2 and start her up and see how it runs.

The Zeeltronics has now been wired direct to the ignition fuse so its only on with the ignitiuon on.

Today I just had to do a couple of little jobs before the set up tomorrow.

1st job was to correct the oil line as I had a complaint from the club vice chairman for using zip ties to secure the lines at the pump end.
Thats all I had at the time but I ordered the correct clips and replaced the zip ties just to keep the Little bloke happy.




The next problem was the side stand hitting the exhaust pipe.
This is because the pipes sit differently with the new 350cc barrels.



This is the stopper martin made for the original set up so I removed it and bent it down a bit in the vice.



And now its perfect.



Then there was the damaged mirror, this mirrow was damaged before it went on the bike as I donated them from my RD350LC (they were on the bike when I got it)

It really annoyed me so I ordered a new one for Project X out of my own money.






A nice shiney new one.





Then I found the YAMAHA sticker that Norbo gave me so I stuck it here.





Oil pump now primed (thats so much easier with the 350 pumps) and we are all ready to run it up tomorrow.

Hate to say it Paul but the pipes from the pump are incorrectly routed - They should all go over the guide bar as shown





From the 250 / 400 C/D manual


Just as well they are easy to bleed  ;) ;D




EDIT - They are put over the guide bar so that nothing interferes with the cable.

I knew the two feed pipes went in front of the guide but I did not realise the main oil pipe went there as well.

O well another job for tomorrow

I have not fitted the cover yet anyway.

I will have to do the same on my 400F as well.

5 min fix, no need to undo oil pipes.


Undo cable from pulley
Route pipes over bar
Route cable behind bar & attach to pulley


Jobs a good 'un

First job this morning was to move the oil lines to the correct position before RD nuts comes round for the start up.



All done 2 minute job.

Then RDnuts arrived so we scoffted dowm a load of bacon buttys and a cup of tea before work started.

Set the timing to 3.5 BTDC









With that done its time to put it back together.



Now its programe the Zeeltronics, we decided to use the pre-set curve 1 installed on the computer and limit the revs to 9000 RPM.
This was just a matter of pressing a few buttons and pressing enter, job done.



Then third kick and it burst into life.



A little test up the drive.







Its a lot louder than before and all apears fine, sounds nice and no rattles.

RDnuts had a little go.









I put it back on the ramp and some bugger stole the seat, anyone seen it?



I will take it for a blast when the rain stops and run it in for a FREE MOT compliments of Braishfield Garage Ltd

Thank god its all finished, I will be glad to get it of my ramp.
RDnuts and myself started doing this before Christmas but waiting for parts etc takes time..

Why 3.5 btdc seems a long way from standard, or is that because og the zeeltronics?

Thats what we thought so we read the Zeeltronic instructions again and it is 3.5 BTDC so then I contacted Botut at Zeeltronics and he confirmed this.
I also spoke to Gazzatt2 as he fitted the system and he had set it to 3.5 as well.
He had checked the setting twice as well.

Good to see the full 350 mod.  Any chance of putting it on the hot topics Sticky?
The zeeltronic is interesting.  Any chance of saying what the program curve actually is (in degrees/rpm)?  Cheers
