My hobbit was running 'ok' before. Four stoking alot and running very rich. It would get up to 30 but would four stoke and not go much past. Also it didn't like to idle, but i think that was an intake air leak.
When I installed the pipe I put Red high temp RTV (as mentioned by a fellow MAer) on all intake surfaces (reed block-crankcase, intake-reed block, carb-intake).
With the new pipe and intake seal the hobbit runs awesome. It only four stokes when going down hills at full speed. Not sure about the top speed as my speedo cable broke. I assume its around 35 or so judging by traffic.
Low end is really sluggish but once its start moving the mid pull is awesome. Good top speed cruising.
The low end is the biggest issue right now. I think that is attributed to my low compression. the last test i did it only had 90psi. I have new rings and gaskets to rebuild it.
I also was to check out the variator, I don't think its operating at 100%. I think I hear the plastic caps rattling around in there.
Those are the next projects.
But as far as the pipe goes: I would say it was well worth it. Install was easy, build quality is good and it very much improved my ped.
