You have a nozzle on the end which is the LS needle, but you have a tap at the wall which is your HS needle. You open the tap a turn so you have good water pressure flowing through the hose, then you adjust your nozzle so that the water shoots say 3 feet. Now if you go back and close the tap 1/4 turn the water will still come out of the nozzle but it might only go 2 1/2 feet. To get it to go 3 feet again you probably have to go back to the nozzle and adjust it a bit. The exact same thing happens with the carburetors. If you lean the HS needle that means that less fuel is flowing into the carburetor so you have also leaned the LS needle. If you want the same amount of fuel flowing through the LS needle then you have to go back and open it up (richen) slightly to compensate. This is what I was talking about in my last post. The issue that you are experiencing is a typical sign of an engine being set too lean and it basically over heating. So to compensate for that we are going to richen the HS a tad bit which should keep the engine from getting so hot. However you mentioned that when you first go out that the idle is perfect and the bottom is good, so it sounds like you have the bottom end setting good. So to keep this the same if we richened the top a few hours we now need to lean the bottom a bit to compensate just like with the garden hose. Make sense?

I have been using o 97t plugs for breaking, I will be sWitching to werks#5, question is should I expect to have to adjust settings or should everything be ok with the change.

Probably have to retune. Just put ur lsn to flush then in 2 hours n hsn should be flush then 5 hours In. That's what I do. Iv had a super lean bottom b4 running anything other then sirio based plugs, the closest is the p3. Nothing else to me works without a lean bog on bottom. The sirio/werks 5/6 plugs r incredible to say the least, iv had one going for over 3 gallons now n I'm starting to b shocked cause I'm pinned all the time. Hope a filament don't get me keeping it in so long.

Ok guys, I have raced my first race with my new B5 in a Mugen MBX6T, all I can say is this motor has major speed, so much that I will need to reduce my EPA on my throttle to slow it up a bit, this motor has tremendous power, I did have my needles a too lean causing a high idle, my air gap I believe may have been closed too much or not open far enough, I have about a dime size gap and the idle is perfect, no flame outs during racing, if I had to post a negative it would be that I got 9 1/2 minutes run time, this is still a new motor and a bit fat, so maybe i will be able to lean it out a little down the road and get the 11-12 minutes that some are reporting, I am using a 2013 and love this motor pipe combo, I am now a loyal werks motor user and no werks do not sponsor or pay me for my feedback as a matter of fact I am a rookie, but I know I will be beating those guys with the 400 and 500 motors you can take that to the bank.

But the one thing that matters most to me is customer service, and I have not seen the greatest customer service since I have entered the RC scene, but you cannot ask for better support than what Ron provides from Werks on this forum, problems are addressed quickly and solid advice to problems provided even though many variables may exist for everyone using these motors, I will be purchasing a new buggy and guess what is going in it? You got it Werks B6 Pro.

I don't know why they disappeared. I've asked the same question on the B6 side but no answer. They had a special on the b5 pro for 214.99. I grabbed me one. I looked the next day and it just disappeared from catalog. The b6 pro is still available though.

Hi for buggy I'd go with the B6-Pro. Pair that with the 2058 pipe set and you will be dialed! Regarding break in instructions those can be found in the first post of the B2, B5 & B6 thread. It's a pretty simple and straightforward system. Just read through it and if you have any questions let me know!

Ron I was thinking of running the 2057 with my b6, should I be looking at the 2058, I want to order this pipe today. The track I run at is big and technical, it will be changed next month for the nitro challenge.
