boner Posted March 18, 2008 Report Share Posted March 18, 2008 Was observing at a local twin shock event last weekend, and someone had a Benly powered bike - which for me was bike of the day! It had a lovely sound to it. Missed the chap at the end of the event, as I was still walking back, but found out from a friend that the chap had built the bike himself. Was wondering if anyone else out there had a Benly powered bike? Cheers - Boner. Quote Link to comment Share on other sites More sharing options...
michaelmoore Posted March 18, 2008 Report Share Posted March 18, 2008 (edited) Not exactly an early 1960s 125cc Benly twin, but here are some later 60's CB160/175 twin specials from my website. The first two are in the vintage dirtbike/trials photos: "After two seasons running a 90cc Honda trials special, English dealer Ken Ives built a CD175 engined CB160 trials bike. Low compression, lower gearing, upgraded forks, trials spec wheel diameters and tires made a nice trials bike. Photos from 07 Feb 68 Motor Cycle." http://www.eurospares.com/hon175t1.jpg http://www.eurospares.com/hon175t2.jpg From a page devoted to 160 trials bikes ( http://www.eurospares.com/cb160t.htm ): A special that appeared in a 1969 magazine: Mr. Deeter had overbored the engine to 180ccs, and fitted a single carb head from a 175 Honda. The compression was lowered (method not specified), a milder cam from a Honda CA was inserted, and a brass flywheel fitted to the back of the alternator rotor where the electric starter sprag clutch would normally go. He also built a 2-1 high pipe with fairly short head pipes and a very long tail pipe. The bike was lightened with an aluminum fuel tank from a Van Tech frame kit and Akront alloy rims (19" front/18" rear). A small hub from a Honda S90 was used in the front wheel, and attached to forks from a CL160. The bike was reported to weigh 215 pounds, and Mr. Deeter figured he had a year of part-time labor and $1000 invested in the project. http://www.eurospares.com/deeter.jpg As far as I've gotten with my CB160 Premier Lightweight special inspired by the above bikes: http://www.eurospares.com/160a.jpg http://www.eurospares.com/160b.jpg http://www.eurospares.com/160pipes.jpg I've grafted an 160 alternator (internal) rotor hub into an (external) alternator rotor from an EX250 Kawasaki Ninja to increase flywheel mass. The ports have been filled on both sides http://www.eurospares.com/160ports.jpg Dished XR100 pistons: http://www.eurospares.com/160pist.jpg cheers, Michael Edited March 18, 2008 by MichaelMoore Quote Link to comment Share on other sites More sharing options...

michaelmoore Posted March 18, 2008 Report Share Posted March 18, 2008 Dave, I've noticed that the threads here with a lot of photos (especially where people have "quoted" the original post with the photos several times) take a bit of time to load even with DSL so I thought I'd avoid loading 8 images and slowing things down for others. And anyone who wants to see them can easily click on the links. Old-fashioned Internet courtesy habits can be difficult to break. cheers, Michael Quote Link to comment Share on other sites More sharing options...

Or better yet I've seen so BB software that doesn't allow it. Quote Link to comment Share on other sites More sharing options...
overthehill Posted March 18, 2008 Report Share Posted March 18, 2008 I wouldn't take my Benly anywhere near mud and your right Boner - they sound lovely especially when fitted with original 'race kit' meggas. Quote Link to comment Share on other sites More sharing options...
michaelmoore Posted March 18, 2008 Report Share Posted March 18, 2008 On open megaphones my "CR216" that I designed and built was measured by my local race club at about 130dB. That's pretty uncomfortable to be around in the pits but sounds good out on the track. This photo was at Laguna Seca before I installed the fairing. cheers, Michael Quote Link to comment Share on other sites More sharing options...
peterb Posted March 19, 2008 Report Share Posted March 19, 2008 Hi OTH, I had one of those Benley's about 40 years ago (I were just a lad). I thought the tank was a superb shape, yours is a good example. I seized the big ends, not cleaned out enough during a strip down (well, I was pretty young then), put in another motor then swapped it for a YS 1 I think (Yamaha 100 twin) plus cash - seized that too! Bye, PeterB. Quote Link to comment Share on other sites More sharing options...
boner Posted March 19, 2008 Author Report Share Posted March 19, 2008 Gosh, you look away from your computer for two minutes - and you get loads of posts! Scorpa250 - that's where i saw the bike, at Roger's meet. The bike in perticular was the Gazelle, sounded great - not too sure about the yellow and brown paint scheme though! Didn't spot the other Benly, will keep my eyes peeled on the 13th. Some nice bikes out there - and some serious work. Thanks for the replies. Cheers - Boner Quote Link to comment Share on other sites More sharing options...
