got a ? just put a losi 8t fly wheel on and it rocks on the shaft at tdc tight. i hold the nut and it rocks some. the nut is way tight .

You were right. No pro b5 and it's one of Neil's motors. Wish I was aware of it. But nxt question, on amain a new b5 is $199 new complete and parts such as a new piston/sleeve, rod, and wrist pins clips/pin will come close to $199 also, well a few bucks less. Just curious on how pricing is worked out? Seems like I'm better off buying a new b5 and keeping the crank shaft and bearings as back up. Not sure what to do with an extra case, carb etc maybe sell it new and get money back. Is there anywhere to buy the sleeve set complete without spending the cost of a new motor?

Never heard of the fly rocking. Did you place the Losi small collet on first then fly wheel then Losi nut? You have to make sure all the parts are Losi. I use to forget that rule all the time and wondered why the bell never shimmed right. But it sounds like you are missing something.

I believe a Losi fly wheel requires the use of a Losi collet (different angle). Someone else can confirm. I don't involve myself with Losi, but I believe I read it on an old post.

i used the parts that came in the kit not with the motor. . i can hold the nut and the fly wheel truns some 1/16 to 1 /4 play i tryed to tightin the nut but is way tight. i think its in the rod play

If you are talking at TDC then all engines do that. There is a position between roughly 11pm and 1am on the clock face where the crank pin when the crank is rotating stays on the same horizontal plane.

Hi truthfully the answer is simply that we are selling the B5 for less than what we really should be. The most expensive component inside an engines is the piston & sleeve, followed by the crank and the carb, Most of the time when the majority of the internals nee to be replaced I just advsie the customer to pick up a new engine. That way you have fresh equipment but at the same time you have a back up parts if needed at the track.

Ahh I see now and muched agreed and hate to say it in fear that it will go up but yeah very under priced for the performance it puts out. But thanks I understand now. :D

The fly moves whiles the crank is held? I would assume the fly isn't fully on the collet and you might have more room to go to making it tight. If the nut and wrench you are using are in new shape(not stripped or worn), you might want to see if u can go tighter but don't strip it. Wanna post pics of the collet used and flywheel?

I had the B5 w/ Losi 4-shoe flywheel and HAD to use the Losi collet. I think it was a shorter (could be the different angle you were talking about too).

I don't think the problem is the collet, shortness or angle. I run mugen and just sold my Losi stuff but still have a lot of Losi items left like clutch set ups. The collet only effects where the fly will set on the Losi roller. He has play or a section of slipping. I'm using on my truggy I'm using a mugen collet with a Losi flywheel for the four shoe with a mugen bell. Works fine but had to shim it right. It's a temp Til I can go m2c but no play. His problem is something else. Try another collet to see if the problem is still there. I think something is not matching in the set up.
check the pics to see if your 8t parts match the ones posted
Small collet is for Losi 8ights

its all losi stock set up.

My first race with the new B5 was this past Saturday and all I can say is WOW. This motor screams down the straights and has plenty if not to much power to rocket out of the corner. I installed this animal on my Losi 8ight 2.0 and I had to add the 6mm venturi to calm her. During my heat, I BLEW out my front foams from the tires and was amazed. Oh yeah, I started last out of 20 buggies and I pulled home a win for Team Werks Racing.... YEAH BUDDY...

Thank you for picking up one of our engines and congrats on the results! There is nothing better than taking home a win the first time out with something new! The B5 in buggy is going to be a beast with punch galore! Here are some tips if you are trying to alter the power delivery. To reduce bottom end go with a heavier weight flyweel, lighter clutch springs, less grippy clutch shoes i.e. if a hard & soft aluminum shoe is available run the hard or run carbon shoes. To reduce the top limit throttle opening or reduce venturi size. Hope this helps!

Thanks
 

Thanks for the congrats. I added the 6mm Venturi to reduce the intake and that seem to do the trick. I purchased the werks racing (medium) pro clutch already and I truly love that thing... Any chance you would know what springs should I change to help power delivery. I think the package came with silver and black... And I can't find instructions on those any where... Thanks alot
