ok I guess I have been away from this way to long. Need some help on attaching the carb. I have the carb, the sleeve for the shaft, rubber thing, and a black metal thing that looks like it is 2 pcs. I know it shouldn't be to hard, but HELP:confused::confused::confused::confused:

bguad 11-14-2009 07:14 AM

Oh I forgot to mention I have a Werks B5

Werks 11-14-2009 08:45 AM

Lol, bguard you have been away for a while ;-) So you have the carb, a sleeve for the crank, a rubber thing and a piece of black metal that looks like it is made of two pieces. The sleeve for the crank should be made out of brass and is the collett. The rubber thing that is black and looks kinda like a donut is the exhaust gasket, put this on the engine by the exhaust port. The 2 piece black metal thingy is the carb pinch bolt. It's actualy 3 pieces so start by taking it apart by unscrewing the screw. Once you have this out the 2 halfs of the punch bolt should be loose. Now insert your carburetor into the engine making sure that it is seated fully. Once this is done inser 1/2 of the pinch bolt on each side of the engine case in the wholes situtated by the base of the carburetor. When doing so please make sure that the cut outs in the carb pinch bolt half's (that is designed to sit flush with the round carb base) are facing towards the carburetor. Then insert the screw and tighten drawing together the two half's of the carb pinch bolt until they... Pinch the carburetor lol and it is nice n tight. That's it! For the rest please make sure that you follow the break in directions that I wrote towards the begining of this thread and if you have any further questions do not hesitate to ask.

Regards,

Ron

hey ron...
 
ron, hope you can help me......i was fortunate enough to get a B5 from a-main a few weeks back. followed your break in method, as indicated earlier in this string, step-by-step(including getting the piston to BDC during all cool-downs). problem is that after bout 9-10(160cc) tanks of break-in i now have no pinch and very little "thump" at TDC). the engine seems to pull strongly, though with plenty of smoke running in the 22-230 range on byrons 30% race. my concern is for the longivity of my engines piston/sleeve. i need a strong engine(that's why i picked the B5) for a big race(motorama) in february. can you help out, ron..??

I bought this motor for my truggy and a buddy blew up his OS and needed a motor, so I sold him mine new in box. Well he broke it in this weekend and I cant wait to get my replacement cause this thing is SICK!! Absolutely incredible power, throttle responce and the run time is incredible!! Glad I chose this motor and so is he, it took some convincing to get him to try it but he is glad he did. Great product at a great price;)

Hello alexrckid, thanks for picking up one of our engines. I looked over your post and I'm not quite sure what problem I can help you with. Based on your description it sounds like your engine is just broken in and running properly. Metal pinch is not a good thing as it results in friction which robs power and puts strain on your rod etc. (which often needs to be replaced after break in with other engines). So right now it simply sounds like your engine is fully broken in and as you said "the engine seems to pull strongly, though with plenty of smoke running in the 22-230 range". If the piston/sleeve is worn out prematurely you will see this through a lack of compression which is immediately noticeable through an inability to get the engine to idle properly. As long as you are not seeing this and your engine provides good power and runs properly I don't think that there is anything for you to be concerned about. Just run it at race tune as you have been doing with the expectation that you should get the usual 6+ gallons out of the P/S before needing to replace it. If you see anything less than this just drop me a line and I'll work something out with you.

Regards,

Ron

rooke-e, glad that you and your friend liked it! People just have a hard time believing that you can get such an awesome performing race mill at such an affordable price! Glad that he liked it and thank you for converting him!!!

I'd give either A-main or RC Planet a shot at

http://www.rcplanet.com/Werks_Offroa.../wrxtl21b5.htm

Both of them should have stock right now.

Ron

Does the B5 like the Ofna 053 pipe? What would be the pros and cons of using this pipe on this motor. I have the pipe, not the motor (yet).

greenracing 11-16-2009 02:38 PM

run the motor again yesterday and i made 2 changes: from a 2 year worn down OS 2060 to a new RE10 and from nitrotane 20% to Byrons Gen2 30/9 and WOW!!!! i can say for sure, this beast is more powerful than my previous power-plant (OS Speed)
qualified 5th in the A main but when i was doing warm-up laps the rain started and we were done. This motor has about 1¼ gallons of fuel and it feels awesome!!! later my friend that was pitting in the qualifiers said to me than 5 people asked what motor i put in the 1/8, "it is another Speed? nope..it's a B5" jejeje one of them come to me and asked me if i have a speed block with a B5 head lol i said of course not!! this is a fully Works B5 .21 mill!!! i think there are people that doesn't believe what a 190.00 mill can do!! well more and more people are seeing and believing:nod::nod::nod:

B.C.Ninja 11-16-2009 06:36 PM

Hey Werks, since the mill is made by sirio is there any chance that the conrod would fit a CL7B, I recently purchased a B7 and Wow, it performs just like my JP Eagle did but the eagle lost its wings as well as the lower half of the piston hmmmmm, and now my sirio conrod resembles a fish hook, split the thing vertically right up the middle and now can't find one anywhere hence why im looking at the werks conrod.

alexrckid 11-16-2009 07:31 PM

gotcha, ron..............thanks for your input. lovin the engine......guess i wasn't used to such a quick/easy breakin....
