Since I recently got LEGO Technic set 42036 and didn't built anything out of Technic for a long time I've decided to rebuild this motorbike into vehicle with four wheels. It was bigger challenge than I expected. I had to use few uncommon asseblies:

1. replace front wheels by gears with chain
2. replace connector in crankshaft by liftarm
3. replace pair of bevel gears by bunch of connectors - this solution was proposed by Victor Imaginator

Finished dragster features just V4 fake engine with moving pistons. I planed to add steering but I didn't have enough parts for it.

I can't see your pictures.

I can see them on different devices and when I am log out too. I don't know where is problem...

Really nice build! Hard to believe this came from a motorcycle.

Wow!

Very cool C-Model. I should build two of them) Also, nice to see that solution inside)

Nice idea! especially your solution to the front wheels  

That's a smart solution for the front wheels. Your c models are always the best

Thank you all for your comments. I'm happy you like my dragster.

Cool!  That reminds me of the B-Model from 8422 Circuit Shock Racer from 1995!

Ah, I can see your pictures now. Good job! it looks almost as though the set was a dragster, not a motorbike.

I've really used this set for inspiration. Main difference between my dragster and dragster from set 8422 is that mine has seat in front of engine and dragster from 8422 has it behind engine.

Wow, thats a very impressive C model with very nice styling. I didn't think it was possible to change a motorbike into a dragster 

I've just released building instructions for this dragster. You can download them at buildinst.
