Dna Filter
 

Hello Kev, thanks for having responded. The 6mm increased XT600E I took the cylinder recamisado, was placed in an oven, very hot after the hole was removed, the piece was machined and put a new hole, was as much torque and the most interesting result is that the bike vibrates less during the journey, it was more comfortable.
The filter DNA has two versions, the 2nd version turns the whole box of the air filter in and works with a reservoir area of screening much more facilitating the entry of air. The 1st version appears fit on the same site of the original, perhaps it facilitates the passage of air. These filter versions of the same quality and efficiency as the original? The filtering of air, if not good, injures more to life, compared to other preparations.
The control valve that you used in your motorcycle was produced by yamaha?
I noticed that you had another command, Tornado, has already been tested?
Here in Brazil is easy, parts for preparation of small type 125cc bikes, 150cc and 250cc, for XT660R has nothing.
With my XT660R the maximum speed was 172kph, she leads.

The best result is by using DNA stage 1 & 2 filters.

These filters last longer then paper filters, the filters are to be cleaned & reoiled to retain their sealing, I do mine every 6 months.

You say control valve are you talking about the throttle body? If so, yes it is a Yamaha throttle body bored +2mm.

You are correct, I run a Power commander PCIII to adjust the fueling.

Hello Kev, all right?
The power commander III, is installed on the bike?
He changes the original information of electronic injection?
I can choose in which RPM I want him to change the injection electronics?
This cam Tornado is good that you showed?
Good luck buddy!

Right Said Fred....

I do not know anything about this cam, one thing it is very expensive.

Me being me, I can't leave things alone. So with just over a year & 10000kms on the big bore, she is pulled down again.

Last night I pulled the motor out stripped off the head & Raptor cylinder. I have refitted the standard XT660 cylinder with a ported head. Strip down & reassemble & running 4hours & 45mins.

I will do some work on the head with some different cams to see what we can get out of the standard motor. I have plans for the removed Raptor cylinder & cylinder head, this is the main reason for stripping the motor again.

The ported XT head that is now fitted, this was the first stage before polishing. The XT's heads are really bad with big steps around the valve seat area that will disrupt the air flow big time.

looking good Kev. As far as I can see the JE piston still looks in good conditions, the head too.

The JE piston did develop a rattle at start up for 5 seconds from cold. I measured the cylinder to piston clearance today & it is still well in spec, Kenny did warn me of the off set pin on the JE piston so I knew what the noise was & did not worry to much.
