pix of hf

Okay- I'll take pix of it tomorrow and post it. These engines are MUCH easier to hook up to a throttle than a B/S flathead...

 

[jonesie8807]

Thanks again guys. Im almost done. I just have to line the chain up properly. When im finished i will post some pics.

 

[I like karts]

I kept the stock gearing

which is.....? I would like to know this gearing

 

[Jerryburger]

Ooops. Let me go look.....12t on the clutch, 66t on the rear wheel. (5.5:1). The HF 6.5hp is almost overkill on this thing, but since it's cheaper than other alternatives, why not? Right now, the gov. is set at 3100 rpm, because the kids keep biffing it on this thing.

 

[jonesie8807]

Yeah, I had to drill a new set of holes so the engine would line up... the motor doesn't hang out as bad as you'd think. If you want I can post a better picture of it from the top....

Hey man do you think you could tell me where you drilled your holes for the engine? like how far from where and stuff like that. I need to drill my holes but i want to make sure i get it at least close to the right spot before i start drilling. thanks

 

[Jerryburger]

Sorry about the wait, Jonesie! Here is a close-up of what I did...

What I did was "eyeball" it and line up the engine/clutch sprocket with the rear. The holes/slots ended up being 5/8" to the right (sitting on the minibike, looking down). If you had the little Lifan 2.8hp like I did, then you'll need to remove the spacer-block that sits under the Lifan Motor. Check and double check before you start cutting. Also, I have an old B/S block that's been gutted; I use it as a template for the mounting holes.
That's how I did it.

Thanks man. HUGE help!! ill let you know how it goes. OO and one more question lol did you use the kill switch on the bike? cuz the switch on the engine is an on/off not a kill so i wasnt sure if it would be compatible. Also there is only one visible wire coming out of the engine and the doodle bug kill switch has 2. thanks again

 

[Jerryburger]

I definitely have to go out and look. If I remember right, I wired one of the wires from the DoodleBug switch to ground, the other to the HF's kill knob. If the kill knob is "on" the DB's switch doesn't work. This was to preserve the function of the low-oil sensor. I'll trot out tomorrow morning and check my connections. Good luck with the set up.

 

[jonesie8807]

I finished my bike. WOW it accelerates quick i almost flipped it lol. thanks for your help jerry. Now i just need to attach the kill switch.

 

[Jerryburger]

See what I mean? That's why the 80-100lb kids keep biffing it on mine. If I can find a decent motor of less hp, I might put it on and use the Blue Terror on something else.

Hey guys! I am new here, but found your forum by searching for input on the HF blue motors. I just bought a used Manco Interceptor go-cat for my son and found out that the carb was bad. Ended up buying the Blue Motor for it instead of a new carb (it was cheaper that way). Anyway, the point is that the salesman was trying to sell me the extra warranty ($35 for 2 years, $20 for one) and I said no. He then said that he would knock off an extra 15% if I wanted it. I already had a coupon for the engine for $97, so I said what the heck. Come to find out, he gave me the discount on the total purchase, which made the two year warranty only cost me about $13! I just thought that some of you might be interested in checking in to this for your next blue motor. He said that if anything at all goes wrong with it, you simply bring it in and walk out with a brand new one, no questions asked.

 

[kibble]

Ha ha! So apparently this site is jammed packed with references to the, as Jerry said, Blue Terror. You got that motor for fairly cheap!

 

[jonesie8807]

Hey Jerry, do you have any kind of cover over the clutch and chain? and did you check your connection of the kill switch?

 

[ironman]

good deal there. Alwaysssssssssss....... get the warranty you can not go wrong.

 

[Jerryburger]

Sorry Jonesie, I spaced getting a picture of the connections,. I'll go look and post it very shortly. No- I took off the chain guard/clutch cover even before I swapped motors, because it was kinda deformed and constantly getting banged by the chain.

 

[jonesie8807]

No worries im just trying to finish up the finishing touches. thanks and does your engine die when you take corners? i think my low fuel sensor is messing with me.
