I have only heard good things about this clutch and want it in my Cobra GT asap. But have a question which shoes is recommended for a Reds M7T-GT motor. I understand that the standard weight komposite bond shoes are for Off road motor used in GT, and the light weight shoes for On road motors used in GT... So which would I buy??

Also going to try the new crank caps

Thanks
Tony

Just a heads up with a cobra gt the 34mm flywheel is to big. It just wants to meet the rear brake disc! Had a 34mm set up off my DM1 and couldn't use it. Iv been running the stock serpent stuff but its junk. Shoes wear out within 1/2 gallon! I need just a 32mm flywheel to put my shoes and springs on if anyone has a spare they want to part with!!!!

34 mm does work on Serpent. Please make sure to install the bigger brake disc in the front and smaller one in the rear so the buku fly wheel won't come in contact with it.

Yes I know smaller brake rotor in the back had it. With the stock gearing it did not fit! Maybe I got an irregular flywheel as mine measure almost 34.5mm. I going to try it again as I now run different gears. Had a couple people say it should have worked and saw with there own eyes it did not!

Buku web site said the fresh bell needs the komposite shoe to break in, is it avaliable from Buku? I didn't find the komposite shoe available.

The clutch systems come with the Komposite shoes. You MUST run a new/fresh clutch bell with them and not one that has already been run with other clutch materials. Run whatever your favorite clutch bell is. Just make sure its new and fresh.

Thanks! What about the break-in process? Starts from low spring tension in low rpm and run on track?

I've had two systems and didn't do any specific break-in on either of them and they work flawlessly. Took it out of the box, installed and dropped the hammer. Haven't looked back. The ability to tune the clutch on the fly is worth its weight in gold.

It's a good clutch.
Anyway, can light version for on road engine use on GT engine?

Guys, I've been running the standard serpent clutch on my Cobra GT (setup 2 composite and 2 alu with hard/x-hard springs) and have been having good results with little wear. I'm now considering trying the Buku GT clutch. Looking at their website there are 2 versions one with standard weight shoes and one with lightweight shoes.

Now I understand that standard weight if you are using an off-road engine and lightweight shoes with an onroad engine however which should you use for a specific 5-port GT engine like the Novarossi ISON-GT or Picco EMX-GT engine?

Thanks for the help guys.

Now I finally got the answer from trial in error. The first set of shoe is just for test (I never play the centri. clutch before). Now I know how to adjust the spring tension.
I think the standard and light weight are for different type of engine. I'm using light weight shoe on 5 port GT engine, it works good.
I tried the light weight shoe on buggy engine, clutch engage very late and car doesn't want to move, so you need standard shoe on buggy engine.

Interesting, this clutch is sequentially engage, the power is more progressive in low traction track.

Default Bukupower still exists?

Gents,

can't seem to get a hold of Buku. Called them 3 times in the morning. No ringing, phone seems to be off the grid. Do they still exist?
RCpit Box in the uk sells them as well but.....

I would like to know whether the Buku clutch is still available and possibly other Companies who sell them as well.

Default Clutch specs for an Xray GTX 8

Hi guys

Can you confirm flywheel diameter I would use for the Xray??
Also from reading this thread I assume you would use the lightweight shoes for on road GT

Thanks

Jeremy
