After all the mods I did to the wife's MM-80, ''which is now mine'',, because of setting her up with a highly modded electric Lithium Ion MM E- 1000, I ended up getting a jack shaft setup from BMI, which only cost me 90 bucks for everything, including shipping,
The governor gear assy. is completely removed, & the throttle is set with the governor arm & 4 misc. springs...
Intake is custom made by Brad from HRM, & the ''rare'' pipe, is off a MBX-11 , which I also got from HRM.
The gearing is 11t on the clutch, 17 on the primary driven. 13 on the out board driven & 65 on the wheel.
That gives me a gear ratio of 7.727 - 1, from the stock 6.8 - 1.
When I pulled the cover, to remove the governor gear assy, I was surprisingly impressed with the quality of the cam, crank & bearings ect.
Cam is not plastic on this version , & is a pretty decent steel one.
This Lifan 152f-3 engine inside the crank case looks ''a lot'' better than the last 79cc Predator I took apart.
I figure with the mods that have been done ''so far'', the engine is putting out around 3.5hp now.
Am having to spend ''a lot'' of time'' modding the jack shat plate to my liking though. Mostly in long gating the plate mounting holes to accommodate the 11-17t primary sprockets, & to clear the fender ect.
I know that most of you probably think I' am nuts for doing this, rather than converting to a 212,,but I like a challenge that others wouldn't.
Think it will run about 27mph @4,500, after the latest mods,, & pull my 205lb @$$ ''no problem''.
If wanting to go faster, I will just jump on the Harley.
I will post pics tomorrow .
