I am building a CB350 engine for a dual sport creation. By next spring I will have a street legal air cooled twin Honda in a CR500 frame, under 380lbs out and exploring the back roads of Montana.
My question(s) and why I joined this site was to tap into the knowlege base on this motor.
I had one get me through college and more, but can I duplicate that reliability (mostly) with 362cc's and a cam/head work, perhaps a pair of FCR carbs, and a stator rewind for some HID's?
Thanks . . . . . . . Hank

How are you getting it "street legal" in a frame that is not DOT compliant, and marked as such?... The VIN tag clearly states "Not for highway use"....Just wondering as a similar design/modification insanity is on my mind.... ;)
However, I have no doubts that the modified bike will need constant attention to maintain its reliability.... Just like a race bike.....To gain performance you usually sacrifice some of the reliability.....Steve

Steve, several states allow bikes like that to slip through the system. I see guys slip CR500's and KX500's as supermotos, through the system all the time..



Same wheels, hubs, and tires as I've got..

In Virginia, you must have proof of insurance to get/keep it plated..... It's not so much the state I'm worried about....It's the insurance companies.....Their computers "spit" back as a "non-streetable" and your insurance does NOT cover anything...It's Voided....
Here you have to surrender your plates as soon as the insurance expires or face a large $ fine ($1000), plus have to "self-insure", an extremely expensive proposition.....
Plus, every year, there is/will be a hassle getting it inspected.....

Please don't take this as a brag (maybe the pride of low population+high liberty) but the big brother concerns are those of the "coasts" (for now anyway). I know as I am one from the left coast - happy refugee. But I have very contently settled in a state with less than one million residents. My YZ is plated. Hell ranchers plate their quads.
Life is a little different here.
Anyway I rode the snot out of an SL350 through college, no problems, (except a broken femur) I'm curious if any ya'll have a long relationship with the 362cc overbore.
A (possibly) +- 300lb 7/8 scale Paris-Dakar dual sport would be a hoot, yes? Dual HD's a must . . . . . maybe red/white/blue mmmmm

Hank, anything you do to a motor to increase the HP will affect the life of the engine. I have a cl350 that I bought when I got home from Nam and it still is in original condition cept for the seat cover. I have it stored for cold weather but it will kick right off when it gets warm. I will keep it until I can't ride it or my son wants it. Left is stock condition they will run forever if taken care of.

Hank. I have a Boretech 362 SL350 . I understand the increase in hp versus stock longevity theory. My bike has had a few problems. It was built with very high quality parts. I don't see any problem operating the motor under reasonable conditions on the street . I try to avoid high heat operation. The sleeves are thinner and it is air cooled. It is a very good running bike. Also I don't think a stock engine would be any less fun to ride. They are great running motors. Either way they're going to be a lot tamer than the CR500.

Hank don't care ... he hasn't been seen since 2009.
It is good to hear about your bikes though!
