TDC #1, degree wheel on crank with pointer on zero, turn the crank back 60 degrees (anti-clockwise) and take the tooth out that is under the pick up. How do you set up your pickup position. Is it more than 60 degrees? What fuel pressure should be at the fuel rail? What cc/minute are the standard K1100lt injectors? Because it has a 36-1 tooth wheel should it be group fired or sequential? As far as the comp tests goes, I was asked was the gauge acurate? I borowed it from the bike shop so I don't know! If all the above is right maybe I need to find someone else to run a fresh set of eyes over it |

megajolt uses a 36-1 trigger wheel and it says 4cyl - 90degrees 6cyl - 60degrees 8cyl - 50degrees I would assume that is pretty standard across the board for 36-1 trigger wheels Sequential requires a cam angle sensor of some sort. Just using the crank position you can't tell which stroke the cylinder is on. |

Thanks that makes sense, its the first time I have come across needing to change the firing order I wonder what other secrets there are. |

Post subject: | Re: Phase two of Clubman Project "Twinky" |
no secrets,,, just a few fiddly things to make, mod & procure then it`s just business as usual same as building any other engine just put it together & you`re away but it helps if you have everything right before you try to start it of course |

slacko wrote: Hi Steve Any news ? Hi Mark Everytime we think we have it sorted it turns to crap. Had to replace $280 dollars worth of AeroFlow black braided fuel hose the other day. I've never seen anything like it, it looked like a garden soaker hose. Fuel was just oozing out the full length of the hose, and it grew a couple of feet longer. Aeroflow said they had a whole container of faulty hose and I got some of it. New stuff is in and we're back to the drawing board. So, the next job is to replace the 150.8cc BMW injectors with 220cc replacements and replace the BMW regulator with an adjustable one. The fuel pressure at the rail is 35lbs, but I think we need more. The fuel pressure was suggested as a problem a couple of weeks ago by one GR's race buddies, thanks Santino. Wish me luck I need it. |

Sounds like you have a good logical way forward. Fuel hose turning to jelly not good: probably a good thing getting 'clean injectors' anyway Keep your head up, just a couple more jobs to go |

So close yet so far. Must be so frustrating to be at this part and not be able to drive it. Probably not what you want to hear, in a way its good because this helps all those others undertaking these types of builds. Enjoying your build look forward to seeing it one day. |
