Update
My HF 50cc engine will out perform my Honda GX35 (35cc) big time ! Let me know what you think between your HF vs. Subaru ! Good luck !
"BIG TIME" is an understatement! I just finished my install yesterday and was riding into the nighttime hours. What a blast!
Coupled to the CVT, this engine really lets the CVT get down to it. The bike accelerates like crazy; don't know the top speed as my speedometer fell off 2 weeks ago and haven't replaced it yet, but easily doing 30+. Was on a 30MPH road last night and was coming up behind a car just before I had to turn. Up hills near my home, it kept pulling strong where the Robin would start to lose it and slow down below 20MPH.
The EHO35 clutch practically fell into place on this motor.
Had to do some re-tuning of the CVT weights and got the thing cruising at 6200RPM. At one point with the lighter variator weights, it revved over 6800 before I backed off of it. And that was with me on the bike at speed, not unloaded with the wheel off the ground! Started easily; primed the bulb, choked, and 3rd pull came to life. Warm engine starts were all 1 pull!
On sale and with 20% off coupon, $80. I did get the 1 yr X-warranty for another $12. So with tax, right back up near $100.
Thanks Porkchop for your input in this.
The Subaru is a great little engine, but I don't get where people claim this huge torque and such with 4 strokes over the 2 stroke. The EHO35 will find new life on my wife's bike as a friction drive again.
Great value; great power/speed; easy installation. Hope it holds up.
