      Hey Pablo

      Sorry to bother you, but I thought you could help. My 66cc is doing very well, but after I ride I chop plug to see how its burning. I've got 400 mile on this engine and it has always been a good chocolate color. I took out other day a few miles and checked plug after ride. The plug (NGK B6) was snow white in center. So, bike still idled well, ran out well, but white>? Confused? I've picked bike apart trying to find a air leak. Bike runs as well as it ever has still????????
      Glen PS- Someone said when they burn perfect, they self clean?
      I've always used Amsoil synthetic also.......................... Thanks?

      Um sorry, can you email or PM me? VM's don't autonotify and they are kind of not the best form of communication. I did not even know you had asked me another question.

      Ultimately you won't lose a LOT of power if it's not perfectly tuned to the pipe, but sounds like your plug is good. I don't know if you mentioned it, but are your headers matched to your jug? This will give you a decent gain.

      I will tell you once I get it.. :P
      I finally decided to leave the exhaust as is because it's new and I don't want to mess with it, but will I lose alot of end power in return? (It's kinda really bothering me.)

      Maybe - how hot does it feel?? (I never checked!!)

      perfect chocolate tan at top speed and a little darker at idle..
      Can I put a sticker on the stinger of the exp. chamber without it getting melted?
      If not is there any other place on the new exhaust that is cooler??

      What is your spark plug telling you?

      Of course I read them before asking you but thanks anyway.
      I think it's all about triall and error now.. :)

      There is no one best length - please read the tuning instructions under downloads on our site. It will probably be a bit shorter than as received. Thanks!

      Hi Pablo -

      Disregard complaint of previous message. I looked at the bike in better lighting. The clutch-side 3-bolt bracket has twisted upward to its limit, allowing the jackshaft to become off-horizontal. That's my problem. The jackshaft frame is not twisted as I stated.

      I just have to work some way to keep that left-side bracket from twisting upward. Maybe use a bolt through the strengthening angle and tighten using a turnbuckle arrangement. Anchor the fixed end to some bolt on the engine crankcase....

      Anyway, thanks for your time.....

      Hi Pablo -

      I wanted to run this one past you...

      I purchased one of your shift kits back in mid-2009. It works as advertised. Last week, I corrected some problems internal to my Frankenmotor (a Nantong 80/66 pot-metal engine from some backyard Chinese scrap recycler. Maybe you know the type....)

      Anyway, I tightened all connections, put on some vibration-damping weights on the seat tube and down tube, squared the engine and jackshaft frame to the bicycle frame, and decided to wide-open the throttle in 3rd and 4th gears. I finally broke through the 4500 rpm "vibration barrier" and took the engine over 5500 rpm several times. I use a SenDec Tachometer.

      The engine has not exploded or imploded yet. I am waiting for it to happen.

      After the run (42 miles) on secondary paved roads I noticed the jackshaft chain between the bottom bracket chainring and the 12-tooth shaft sprocket had way too much slack it it. I thought "The chain could not have stretched that much, not after 42 miles and it was good and tight before the run."

      I was right. What happened was the vertical jackshaft brace, the one that is u-bolted to the seat tube, had TWISTED to behind and downward from its default position. Maybe 5 degrees, but visibly noticeable. Because of the rearward slant of the seat tube, the driving 12-tooth sprocket is out of place, cannot tighten the chain, and will not return to its installed position. The chain slack allows me to very simply slip the chain off the bottom brack chainring.

      Now I know that these pot-metal engines should not have heaps and gobs of horsepower, especially where I live at 6200 feet above sea level, where we derate engine max-power output to 75% of sea-level power.

      I did not expect the kit plate to distort like that. I am now thinking that I will place idler sprockets on both up-go and down-go sides of the chain to keep it tight and from flying off the chainring.

      Have you ever seen this before? I am riding a 1993 Haro V3 mountain bike of 4130 steel. Could the tubes have distorted that much to induce twist in the jackshaft frame? Any other advice you may offer?

      Thanks,
      MikeJ

      Pablo: I purchased a SBP black expansion chamber a month or so ago and there was a SBP sticker in the box. I would like two more! (My 5 year old daughter must have got it) I want to put them on this build. How much are they? PM me back, and keep up the good work!!! ...............THANKS.................Dan

      We are working on a couple items for the 4T engine now that we have the 4 stroke shifter kit. We just run out of time every day, every week, etc. I wish someone could have videotaped me busting arse making today's shipments. I was humping.....it's become almost robotic...I'm like a shipping animal.
