Installed Cool Head with 20cc dome

[richybanshee]

A few weeks a go I called Fast Farm Toyz to purchase a CoolHead with 20cc domes, K&N filter and a timing plate. They did not had the Cool head, at the time so I waited like a week before I was pm about it (No problem, since I was not in a hurry). The service was great. Shipment took just 3 days (US PS). So, this past weekend I installed the cool head.

Installation just took me like 2 hours, and I had never installed one of this before. Note: I did my assigment and reed alot before actually doing the job, and also purchased some needed tools like a torque wrench, and Compression Tester (optional), among others.

 

 

After taking the gas tank out of the way I did a compression test with an Actron Compression tester. Since my bike is basically new, only rode it like 10 times I was specting compression to be between 100-120. As I had spected, compression was 110 constantly on both cylinders. Altitude is like 700 feet over sea level.

When I finished the head installation and filling the shee with new coolant I checked the compression and it was bump up to 150. This is a gain of 40psi over stock. Did not rejet. Still I will checked to see If I can get more power.

 

Now, the real test ... riding it.

The power at lower rpms was bump up, with this mod you can feel the difference. I went trail riding the bike felt stronger and without the need to shift toomuch.

Importanly, the bike never overheated.

 

I really recommend this mod.

 

My mods:

CPI inframe pipes

K&N filter with outwear

stock airbox with lid removed

Noss Machine Cool Head with Fast Racing Logo (silver) and 20cc domes

jetting: 320 mains, jet needle in 4nd clip position (2nd notch from top to bottom), pilot 2 turns out

fuel: 93 octane ... any brand

temperature is like 87 F

 

Next week I will install the timing plate, set it to +4 degrees, rejet and see what this baby(the bike) can do. :biggrin:
