Speeders Only!

I thought I would ask all of you about the speeds you can reach with your bikes. Please list your model - your top speed - and any mods done to engine or carb - or anywhere else.

My 1970 ST70 - 50 MPH - No mods yet other than a K&N ait filter. Bought her for $1200.00 US and she was in pretty rough shape but 3 weeks of cleaning and pilishing and lubing brought her around to life again.

ST50 - 1976 - 10" Michelin S1 - 15/35
Honda 50cc AB27 4-speed manual clutch, all original except carb (Shengway 16mm) - 40mph

ST70 - 1972 - 10" Michelin S1 - different sprocket set-ups, mostly 16/32
ST70 all original 3-speed: 40mph
same engine ST70 manual clutch: 40mph
Honda SS50 4 speed, Honda CB manual clutch, 18mm Keihin carb: 45mph
Honda ST70 with Kitaco Ultra Clutch, 88cc Takegawa OT Superhead, Monkey 4-speed, 18mm Keihin carb: 50mph
Honda z50j 4-speed with Takegawa 106cc OT Superhead, Takegawa OT special 4-disc clutch, Mikuni VM26: 70mph
Same engine with R-stage head and Keihein PE24: 65mph
Honda AB02E engine with new head, fast cam, 85cc, original manual clutch and 4-speed: 50mph

Sure I have forgotten about some of the engines.

This is very interesting. At the end we can do an average just for fun!

I took my standard air filter box off and put on an open type K&N air filter and the speed went up from 45MPH or so to over 50MPH right away with just more air. I had to adjust the mixture and idle but that was real easy. Lubing the chain seemed to help a bit also. I've a feeling a lot of them out there are not getting full throttle due to adjustment being not set right on cable. Just my opinion.

That said, I like the stock look of the standard air box and still have it for replacement.

Have fun and dont go too fast
