Andrews CT90 / CH150 commuter scooter "FrankenCycle" 
Andrew sent me an e-mail with details and pics of what I thought was a very sensible "project" bike and one that should serve its putpose well. "Big wheeled" scooters have proven very poular and the advantage of larger wheels on potholed roads or uneven surfaces is considerable. While it's a home project, it looks like a very well thought out and executed one. Andrew lives in an area with lots of winding twisty roads that would make this creature a delight to drive.

Hi Doug:
It is good to see that there are people out there that appreciate the exceptional 1980 s Honda Elite scooters. My situation is a little different. I have a 1976 Honda ct90 , which after blowing the 90 and subsequent 110 cc engines once too often (hard core 44 mile commutes), I am going off the deep end. At the local bike junk yard in kelownas westside, I sourced a 1985 CH150D Engine/powertrain with all the ignition and charging circuit goodies. The next step,I removed the ct90 engine,swingarm, and rear wheel. Then I fabricated new brackets to accomodate the elite engine pivot assembly (after rebushing the seized pivots with bronze inserts and grease fittings). I have installed the engine forward enough that the carburetor sits where the original 6v battery was. The wheelbase of the bike has increased by about 5 inches. The radiator (yamaha 250 dirtbike) is huge but fits perfectly just behind the skidplate downtubes.The 12v battery resides where the original engine was. You would be surprised at how many parts from 2 vastly different bikes can be mixed and matched together. The new 12v electrics are phenomenal compared to the 6v crap. I have named this "thing" the Frankencycle.
I sourced my scoot for info and built an exhaust header out of a 1969 vwbeetle intake manifold, ported a new intake manifold , and installed a huge K&N air filter. This contraption runs superbly, and is almost ready for the road. I will send you pictures of it soon. I think you will get a real kick out of it. Maybe a candidate for an episode of "Monster Garage".
