What clutch would you guys recommend for a b5 pro. In a mugen mbx6?
I have not raced in a few years and see a lot of new clutch designs out there.

ok i have a little question about the back plate on the b5. what size are the screws and how can i get them?:confused:
i made the dumb mistake of leaving them all out and running the motor. needless to say i had to replace piston and sleeve lol. yeah i know dumb right. but i just relized i cant find any screws to fit the back plate grr..

Werks Medium flywheel. with stock settings to start.
I personally ran the 32mm on the mugen even though it comes with a 34.

I've been running a 4 shoe M2C clutch, the only complaint is the shoes seem to wear out fast. Just got a new Reds Racing clutch to try out, I'll keep you updated on how it works out. The Buku clutch and Werks is also nice

Not sure the size, but I bought these and they work.

I am trying to break in a brand new engine. However the carb retainer o rings are broken. I see two extra ones in the baggie but they seem too small to stretch over the carb retainer. Are these correct? Should I use them instead?

Yes they are small. You might want to smooth out the top of the retainer before sliding them over. They are sharp ends and will likely break the new ones. I stretched mine over a pen or something similar in size and slid over from there.

I don't think I have the right o-rings with my engine. I got my package from tower today. The o rings were broken. Here is a picture, the two smaller ones were in a bag separate and uninstalled.

So can I just put any orings on there? Say a shock one which fits? is there a part number if possible. Should I contact tower to send me a new one?

Those are the correct o-rings. From machining the edged of the groove that they fit into can be a little sharp. So when installed at the factory it is possible to nick them (which just like if you put a little snip in a rubber band) can eventually lead to the o-ring separating. So to avoid any potential issues we are including a few spare carb pinch bolt o-rings with every engine that we ship. As Joe mentioned just lube the o-ring up well with after run, slide it over the angled ball end of a cheap ballpoint pen, then put the opposite (flat end) of the pen against the pinch bolt and slide it off onto the pinch bolt.

cool I used the ballpoint trick and it snapped right on properly. thanks!!

Cool, I came up with that idea while I was reading your post lol! Glad it worked out!

LOL my B2 had the same issue as well as one of my Orions. Too bad I didn't have any extra's, so I had to buy an RB o-ring kit. Funny thing though I have always used the pen trick, first try I tried to use tweezers but kept sending them flying and had to hunt for 5 minutes, so then I tried the pen, I actually have one cut down just past the bevel and it is in my tool kit, just Sunday someone asked WTF it was :nod:

It is funny how things work out sometimes as I have found that quite often the solution to a problem is right in front of you. I think that often we over think / over complicate things when trying to find solutions to problems. In this case just thinking about things while sitting at my desk the solution was literally right in front of me lol, I just looked down and the light bulb went off :D

Did the lightbulb go off when I mentioned it in my post above :)

I use the term "over engineered". I use that term a lot at my work!!! LOL!!! Sometimes the simplest methods are the best.
I've got a few little tools or gadgets in my tool box, that I have made out of other things. For instance, broken drill bits do not get thrown out. They get ground down to a point and used for a center punch, or (depending on the size of the bit), it gets used in my Dremnel as a cutting bit for soft materials like plastic.
