Worksman bikes!

Ray,
Thanks for the measurements. How's that 4 stroke run?

Dave,
It's runs so well I bought another one last month.

At 3 3/4" spacing you could possibly squeeze a 3 1/2" Dia tank between the bars which is about the proportions of the Merkel.

Just a quick question, can the drive system you have attached to the engine be rotated 90 degrees clockwise. That would put the drive directly beneath the engine, just an idea I had about positioning a kit type engine and drive system where the output to the wheel is inline with the bottom bracket.

Mike,
Not to detract from what Ray might say but I believe the variable sheave transmissions from Comet can be mounted in about any orientation if you have clearance on the motor base, frame, etc. Mine is the 40 series and came in pieces with no backing plate or cover like the 20 series does.

I think you can take the 20 parts(smaller overall and rated up to 8HP) and treat them the same way. You can orient the parts as you wish as long as you align them as shown in the link.
Here's a couple sites that show some specs and alignment necessary.

Nice thread. Love the Merkel.

Dave,

Thanks for the link, I am somewhat familiar with the torq-a-verter. What is confusing is that some of these small 50cc 4 stroke engine kits appear to have an intergal clutch mechanism built into engine such as the GRUBEE Drive kit. The one Ray has is from EZ Motorbike and is made in the USA. It appears to be similar to the comet drive but maybe custom made for the 50cc 4 stroke Honda or clone with an intergal clutch. Just a thought I had that if this kit could be rotated around where the drive is below the engine and the cover plates are dressed up a bit could be an easy start on a belt drive, stretched, Worksman Bike project.

Here is a great looking build on the EZ Motorbike site.

Hi Mike, You could but the pedals would have to go if it was put on my bike.
