So I’ve had this 07’ StreetBob for about 14 years and I got around 37K out of my 07 96/107. Had the stock compensator go bad which caused trans issues requiring the trans to need rebuilding. When that was done, I began to notice what I would call excessive vibes at low to mid-range RPM. Changed a few things and still couldn’t fix it. So, long road to a tiny house: I decided the 107 was tired since it was still a stock bottom end and 07 wasn’t a great year for cranks. Decided to go with the Zipper’s 124 muscle, DH crank, Timken, with a bunch of other good stuff. Finally got the motor back and started putting it together today. Stand by for more….

Ready for teardown






Short block mounted. I’ll piece it together over the next few days.

 

Nice... That's a lot of motor for a small bike.. Should be a hell of a lot of fun..

 

Who did the work ?

 

Zipper’s Performance

124, Dark Horse Man-o-War, HPI 62mm throttle body, Red Shift 657 cams, stage 4 heads. Should be fun…

 

Sick, definitely be a ripper. Is that the stock suspension on it?

 

I like the way you remedy "issues".

 

Progressives front and back

 

That is some very nice work with your upgrades! Sadly, it's above my pay grade. LOL

What brand of lift is that you are using? Looks like i does a good job.

 

The lift I got from harbor freight about 10 years ago. It does the job but isn’t the best quality.

 

Slowly making progress
