Why not one more. Snowmobile engine deadtail
« on: Jan 29, 2016, 00:34:04 »
This will be a slow going mod podge of bike/ snowmobile parts I have laying around. Cb550 frame with a weld on hardtail. Planning on using a late 60's NOS hirth one lunger smoker engine I picked up a while back. Looking for a 40 spoke 2ls hub. Cvt clutches so she will be an automatic. Gas and brake is all I'll need to wrangle down the road.

Without further adu, here is to one more project.

early 70's NOS hirth one lunger smoker engine …

Could you tell me more about this motor? (We don't have much of a snowmobile culture here in Oz).

I am not the foremost on this motor,but I'll do my best lol. I changed my post, i was made by hirth in the late 60's, and from what dad said, they were a utility engine mainly used for ruining pumps. They were used by several snowmobile manufacturers in the day (boa ski, bolens). Best described as heavy and under powered. Most places say right around 15 horse at the crank. The plan is to 180 the cylinder, hang the carb off the front, and throw a spandy out the back.
